HP HPE7-A01 Aruba Certified Campus Access Professional Exam Exam Practice Test

The correct built-in AOS-CX management role is administrators . HPE Aruba Networking defines the administrators group as the default role with full management privileges and explicitly assigns it privilege level 15 . Members of this group can perform firmware upgrades, modify switch configuration, view sensitive configuration information, add or remove local user accounts, change passwords, and use all supported REST API methods. Aruba Networking

The existing auditors assignment does not satisfy the requirement. The auditors group is intentionally restricted to audit-related operations and is assigned privilege level 19 , not 15. Its CLI access is limited to the auditor context, and its Web UI and REST API permissions are similarly restricted to logging and auditing resources. Aruba Networking

AOS-CX also documents the mapping used with TACACS+: privilege level 15 maps to administrators , privilege level 1 maps to operators, and privilege level 19 maps to auditors. Aruba Networking

Therefore, because this user needs both firmware-upgrade capability and privilege level 15 , the appropriate default management role is administrators .

The correct answer is A. SNMPv3.

SNMPv3 is a protocol that is used to retrieve data stored in a Management Information Base (MIB), which is a database of managed objects in a network. SNMPv3 provides security and access control features that are not available in earlier versions of SNMP. SNMPv3 can also use encryption to protect the data from unauthorized access or modification.

According to the Aruba Certified Professional – Campus Access document 1 , one of the skills that this certification validates is:

Implement and Analyze the output from common network monitoring tools

Configure Port Mirroring to collect PCAPs

Configure NAE agents 9.4

Configure UXI sensors for internal and external tests

Describe how API scan be used to configure, manage, monitor, and troubleshoot your network

The document also mentions that the candidate should have a distinguished understanding of different protocols across vendors, which implies that they should be familiar with SNMPv3 and how it can be used to access MIB data.

a) Support up to 10 devices per stack - >   VSF  

b) Support two devices per stack - >   VSX  

c) Individual ISL links up to 400G are supported - >   VSX  

d) individual ISL links up to 50G are supported - >   VSF  

e) A maximum aggregate ISL bandwidth of 200G is supported - >   VSF

To allow a new VLAN 100 between VSX pair inter-switch-link 256 for port 1/45 and 2/45, you need to use the command  vlan trunk allowed 100 in LAG256 . This will add VLAN 100 to the list of allowed VLANs on the trunk port LAG256, which is part of the inter-switch-link between VSX peers. The other options are incorrect because they either do not use the correct command or do not specify the correct port or VLAN.

This is an Aruba-recommended best practice for hardening that only applies to Aruba CX 6300 series switches with dedicated management ports. A dedicated management port is a physical port that is used exclusively for out-of-band management access to the switch. A dedicated management VRF is a virtual routing and forwarding instance that isolates the management traffic from other traffic on the switch. By creating a dedicated management VRF and assigning the management port to it, the administrator can enhance the security and performance of the management access to the switch. The other options are incorrect because they either do not apply to switches with dedicated management ports or do not follow Aruba-recommended best practices.

VXLAN is a technology that can be used to meet the requirement of using a legacy application that communicates at layer-2 across a layer-3 network. Static VXLAN is a feature that allows the creation of layer-2 overlay networks over a layer-3 underlay network using VXLAN tunnels. Static VXLAN does not require any control plane protocol or VTEP discovery mechanism, and can be configured manually on the Aruba CX 6200 switches. The other options are incorrect because they either do not support layer-2 communication over layer-3 network or are not supported by Aruba CX 6200 switches. References: https://www.arubanetworks.com/techdocs/AOS-CX/10.04/HTML/5200-6728/bk01-ch03.html https://www.arubanetworks.com/techdocs/AOS-CX/10.04/HTML/5200-6728/bk01-ch05.html

AOS 10 Gateways can have the following personas: Mobility, Branch, and VPN Concentrator 1  However, the Mobility persona is only available when configuring a Gateway-only group, which is a group that contains only one gateway device 2  The Mobility persona provides Overlay WLAN and (or) wired LAN functionalities for campus networks 1  The Branch persona provides the Aruba Instant OS and SD-Branch (LAN + WAN) functionality for branch and microbranch networks 1  The VPN Concentrator persona provides VPN termination and routing functionality for remote access networks 3  The Edge persona is not a valid option, as it is not a supported device persona for AOS 10 Gateways.

OSPF (Open Shortest Path First) is a routing protocol that uses link-state information to calculate the best path to each destination in the network.  OSPF establishes adjacencies with neighboring routers to exchange routing information and maintain a consistent view of the network topology 1 .

To establish an OSPF adjacency, the routers need to have some common parameters, such as the area ID, the network type, the hello interval, the dead interval, and the authentication method 2 .  The routers also need to have a matching subnet mask on the interface that connects them 3 .

In this case, the Aruba CX 6300 VSF stack has an SVI (Switched Virtual Interface) on VLAN 10 with an IP address of 10.1.1.1/24 and a LAG (Link Aggregation Group) on port 1/1/1 and port 2/1/1 that connects to a neighboring device. The SVI is configured with OSPF area 0 and network type broadcast. The LAG is configured with OSPF passive mode, which means that it will not send or receive OSPF hello packets.

The neighboring device has an interface with an IP address of 10.1.1.2/24 and a LAG on port 1/0/1 and port 2/0/1 that connects to the Aruba CX 6300 VSF stack. The interface is configured with OSPF area 0 and network type broadcast.

Since the Aruba CX 6300 VSF stack and the neighboring device have the same area ID, network type, subnet mask, and default hello and dead intervals on their interfaces, they will be able to establish an OSPF adjacency over SVI 10 with LAG 1. The OSPF passive mode on the LAG will not affect the adjacency, because it only applies to the LAG interface, not the SVI interface.

802.11k is a standard that provides mechanisms for APs and clients to dynamically measure the available radio resources in a wireless network. 802.11k defines radio resource management (RRM) functions, such as neighbor reports, link measurement, beacon reports, etc., that allow APs and clients to exchange information about the RF environment and make better roaming decisions. The other options are incorrect because they describe other standards, such as 802.11r, 802.11v, or 802.11ax. References: https://www.arubanetworks.com/assets/wp/WP_WiFi6.pdf https://www.arubanetworks.com/assets/ds/DS_AP510Series.pdf

The correct answer is B. Spanning-tree instance VLAN mapping.

To load-balance VLANs with MSTP, you need to configure the same VLAN-to-instance mapping on all switches in the same MST region. This means that you need to assign different VLANs to different MST instances, and then adjust the spanning tree parameters (such as priority, cost, or port role) for each instance to achieve the desired load balancing. For example, you can make one switch the root for instance 1 and another switch the root for instance 2, and then map half of the VLANs to instance 1 and the other half to instance 2.

According to the Cisco document Understand the Multiple Spanning Tree Protocol (802.1s) , one of the steps to configure MST is:

Split your set of VLANs into more instances and configure different MST settings for each of these instances. In order to easily achieve this, elect Bridge D1 to be the root for VLANs 501 through 1000, and Bridge D2 to be the root for VLANs 1 through 500. These statements are true for this configuration:

Switch D1(config)#spanning-tree mst configuration

Switch D1(config-mst)#instance 1 vlan 501-1000

Switch D1(config-mst)#exit

Switch D1(config)#spanning-tree mst 1 priority 0

Switch D2(config)#spanning-tree mst configuration

Switch D2(config-mst)#instance 2 vlan 1-500

Switch D2(config-mst)#exit

Switch D2(config)#spanning-tree mst 2 priority 0

The above commands create two MST instances, 1 and 2, and map VLANs 501-1000 to instance 1 and VLANs 1-500 to instance 2. Then, they make switch D1 the root for instance 1 and switch D2 the root for instance 2.

The other options are incorrect because:

A. Spanning-tree bpdu-guard setting is a security feature that disables a port if it receives a BPDU from an unauthorized device. It does not affect load balancing with MSTP.

C. Spanning-tree CIST mapping is not a valid command. CIST stands for Common and Internal Spanning Tree, which is the spanning tree instance that runs within an MST region and interacts with other regions or non-MST switches.

D. Spanning-tree root-guard setting is another security feature that prevents a port from becoming a root port if it receives superior BPDUs from another switch. It does not affect load balancing with MSTP.

On an AOS-CX switch , REST API authentication uses the HTTP POST method against the login resource. Aruba specifies that a REST API session is initiated by sending the username and password through a POST request. After successful authentication, the switch returns session information that is used for subsequent API requests. Aruba Networking

For changing the administrator password, Aruba documents the use of PUT against the user resource, for example PUT /rest/v10.xx/system/users/admin, with the new password included in the request data. Therefore, D correctly associates POST with login and PUT with changing the management password . Aruba Networking

Option A is incorrect because AOS-CX does not provide comprehensive semantic validation for REST writes. Aruba explicitly warns that configuration errors written directly to the database can destabilize the switch. Aruba Networking

Option B is also incorrect. Read-only mode blocks writes to most resources, but exceptions exist. POST is still permitted for functions such as login , and certain PUT/POST operations remain available. Aruba Networking Option C simply reverses the correct HTTP methods.

Study Guide Topics: AOS-CX REST API, REST Authentication, HTTP POST/PUT Methods, API Access Modes, Read-Write versus Read-Only Access.

The correct answer is C. Create a new SVI and use attach command.

To create a new SVI for a separate routing table, you need to use the attach command to associate the SVI with a VRF (Virtual Routing and Forwarding) instance. A VRF is a logical entity that allows multiple routing tables to coexist on the same switch. Each VRF has its own set of interfaces, routing protocols, and routes that are isolated from other VRFs.

According to the AOS-CX Virtual Switching Framework (VSF) Guide 1 , one of the steps to configure VRF-aware VSF is:

Configure the VRFs on each member switch and assign the SVIs to the respective VRFs using the attach command. For example:

switch(config)# vrf red

switch(config-vrf)# exit

switch(config)# interface vlan 10

switch(config-if-vlan)# ip address 10.1.1.1/24

switch(config-if-vlan)# attach vrf red

The above commands create a VRF named red and assign VLAN 10 SVI to it. The SVI has an IP address of 10.1.1.1/24.

The other options are incorrect because:

A. You cannot attach a VRF to a VLAN directly. You need to create an SVI for the VLAN and then attach the VRF to the SVI.

B. You cannot create a new routing table manually. You need to create a VRF and then use routing protocols or static routes to populate the routing table for the VRF.

D. You cannot attach a routing table to a VLAN directly. You need to create an SVI for the VLAN and then attach a VRF that has a routing table associated with it.

The component that is used by the Aruba Network Analytics Engine (NAE) is D. Current State Database.

The Current State Database is a database that stores the configuration and state information of the switch, such as interfaces, VLANs, routing protocols, statistics, and more. The NAE can access this database through the AOS-CX REST API and monitor the values of any data point using monitors. The NAE can also track the history of the values in a time-series database and correlate them with network events or configuration changes 1 . The Current State Database provides NAE with direct visibility into the entire current state of the device, which enables intelligent troubleshooting and automation of network tasks 1 .

The other options are incorrect because:

A. JSON-based scripts: JSON is a data format that is used to exchange information between applications. It is not a scripting language that can be used by NAE. NAE scripts are written in Python, which is a popular and powerful programming language 1 .

B. Lisp-based agents: Lisp is a family of programming languages that are mainly used for artificial intelligence and functional programming. It is not a language that can be used by NAE. NAE agents are instances of scripts that run on the switch and collect relevant network information and trigger alerts or actions 1 .

C. Ruby-based scripts: Ruby is a general-purpose programming language that is known for its expressiveness and elegance. It is not a language that can be used by NAE. NAE scripts are written in Python, which is a popular and powerful programming language 1 .

Aruba CX 6300 switches support various features to control the port access for different types of devices, such as client mode, device mode, and multidomain mode. These features can help limit the number of clients that can connect to a port and prevent unauthorized devices from accessing the network.

This is because option C shows how to configure the client limit and the auth-mode for a specific port using the interface command and the aaa authentication port-access command. The client limit specifies the maximum number of clients that can connect to a port. The auth-mode specifies the authentication mode for the port.  In this case, option C sets both parameters to multi-domain mode, which allows only one voice device and one data device to be authenticated on a port

These are two benefits enabled by LLDP-MED (Link Layer Discovery Protocol - Media Endpoint Discovery). LLDP-MED is an extension of LLDP that provides additional capabilities for network devices such as VoIP phones and APs. One of the capabilities is to automatically configure voice VLANs for VoIP phones, which allows them to be placed in a separate VLAN from data devices and receive QoS and security policies. Another capability is to request power as needed from PoE-enabled switch ports, which allows APs to adjust their power consumption and performance based on the available power budget. The other options are incorrect because they are either not enabled by LLDP-MED or not related to LLDP-MED.

The correct action to fix the issue is C. Change the SSID to WPA3-Enhanced Open.

WPA3-OWE is not a valid SSID type in Central. OWE stands for Opportunistic Wireless Encryption, and it is a feature that provides encryption for open networks without requiring authentication. OWE is also known as Enhanced Open, and it is one of the options for WPA3 SSIDs in Central 1 .

According to the Aruba document Configuring WLAN Settings for an SSID Profile , one of the steps to configure a WPA3 SSID is:

Select the Security Level from the drop-down list. The following options are available:

WPA3-Personal: This option uses Simultaneous Authentication of Equals (SAE) to provide stronger password-based authentication and key exchange than WPA2-Personal.

WPA3-Enterprise: This option uses 192-bit cryptographic strength for authentication and encryption, as defined by the Commercial National Security Algorithm (CNSA) suite.

WPA3-Enterprise (CCM): This option uses 128-bit cryptographic strength for authentication and encryption, as defined by the Counter with CBC-MAC (CCM) mode.

WPA3-Enhanced Open: This option uses Opportunistic Wireless Encryption (OWE) to provide encryption for open networks without requiring authentication.

The other options are incorrect because:

A. WPA3-Enterprise (CNSA) is a valid SSID type, but it requires 802.1X authentication with a RADIUS server, which may not be suitable for the company’s use case.

B. WPA3-Personal is a valid SSID type, but it requires a passphrase to join the network, which may not be suitable for the company’s use case.

D. WPA3-Enterprise (CCM) is a valid SSID type, but it requires 802.1X authentication with a RADIUS server, which may not be suitable for the company’s use case.

The calculated Equivalent Isotropic Radiated Power (EIRP) for AP1 is 17 dBm.

EIRP is the measured radiated power of an antenna in a specific direction. It is equal to the input power to the antenna multiplied by the gain of the antenna. It can also take into account the losses in transmission line, connectors, and other components. The formula for EIRP is:

EIRP = P + G - L

where P is the output power of the radio, G is the gain of the antenna, and L is the loss of the cable and connectors.

For AP1, we have:

P = 10 dBm G = 9 dBi L = 2 dB

Therefore,

EIRP = 10 + 9 - 2 EIRP = 17 dBm

The default value for config-revision on Core-1 is 0. Config-revision is a parameter that indicates the configuration version of a VSX pair. It is used to synchronize the configuration between the VSX peers and to detect any configuration mismatch. The config-revision value is set to 0 by default on both VSX peers and is incremented by 1 every time a configuration change is made on either peer. The other options are incorrect because they do not reflect the default value of config-revision. References: https://www.arubanetworks.com/techdocs/AOS-CX/10.04/HTML/5200-6728/bk01-ch07.html https://www.arubanetworks.com/techdocs/AOS-CX/10.04/HTML/5200-6728/bk01-ch02.html

To create a new OSPF configuration for a separate routing table, you need to create a new OSPF process ID with vrf name. This will create a new OSPF instance that is associated with the specified VRF and its routing table. The other options are incorrect because they either do not create a new OSPF instance or do not associate it with a VRF. References: https://www.arubanetworks.com/techdocs/AOS-CX/10.04/HTML/5200-6728/bk01-ch02.html https://www.arubanetworks.com/techdocs/AOS-CX/10.04/HTML/5200-6728/bk01-ch03.html

Client IP address : This factor can be used to determine if the client is on the same VLAN as the AP or not. If the client IP address is on the same VLAN as the AP, then the client traffic is bridged locally.  If the client IP address is on a different VLAN than the AP, then the client traffic is forwarded to the gateway cluster through a secure tunnel  1 2 .

Client VLAN : This factor can be used to determine if the client belongs to a specific VLAN or not.  If the client belongs to a specific VLAN, then the client traffic is forwarded to that VLAN based on its IP address and security profile  1 2 .

This is the most likely cause of the issue where the access points in a Microbranch group are online in Aruba Central, but no VPN tunnels are forming. A Microbranch group is a group that contains both APs and Gateways and allows them to form VPN tunnels for secure communication. The VPN tunnels use GRE (Generic Routing Encapsulation) as the encapsulation protocol and IPSec as the encryption protocol. If there is a firewall blocking GRE traffic between the AP and the gateway, the VPN tunnels cannot be established. The other options are incorrect because they either do not affect the VPN tunnel formation or do not apply to a Microbranch group. References: https://www.arubanetworks.com/techdocs/ArubaOS_86_Web_Help/Content/arubaos-solutions/gateways/microbranch.htm https://www.arubanetworks.com/assets/tg/TB_ArubaGateway.pdf

The required optimization is to use IEEE 802.3az Energy Efficient Ethernet (EEE) across the AP deployment. Aruba documentation states that 802.3az allows supported APs to consume less power during periods of low data activity , which directly matches the scenario of reducing nighttime energy consumption. Aruba Networking

However, Aruba explicitly documents that 802.3az is not supported on the AP-315 or the 330 Series , which includes the AP-335. Aruba Networking Consequently, those older AP-315 and AP-335 units must be replaced with models supporting EEE. The AP-515 belongs to a newer generation and does not fall within Aruba ' s documented EEE exclusions, so replacing the AP-515 is unnecessary.

After installing EEE-capable replacements, 802.3az should be enabled across the AP environment , allowing Ethernet links to reduce power usage during low-traffic periods.

IPM is not the primary mechanism for this requirement. Aruba describes Intelligent Power Monitoring as dynamically restricting AP functions when AP consumption approaches or exceeds its available power budget . It is primarily concerned with operating an AP within available PoE resources, rather than automatically exploiting nighttime Ethernet inactivity. Aruba Networking

Study Guide Topics: Energy Efficient Ethernet (802.3az), AP Ethernet Link Profiles, AP Power Optimization, Intelligent Power Monitoring (IPM), Campus WLAN Sustainability.

A failed VLAN Probe indicates that the gateway cluster members do not have the required common Layer 2 connectivity for those VLANs. When the VLAN probes fail, the relationship between cluster members is effectively treated as L3-connected rather than L2-connected . Aruba’s clustering documentation distinguishes these two operating conditions very clearly.

For an L3-connected cluster , only APs are fully replicated . Client/user information is not fully synchronized between cluster members, and high-value application sessions are not synchronized. Aruba’s official ArubaOS 8 Fundamentals Guide summarizes the distinction as follows: for L2-connected members, APs and clients are fully replicated, users and high-value sessions are synchronized, and failover occurs without deauthentication. For L3-connected members, only APs are fully replicated , users and high-value sessions are not synchronized, and users can be deauthenticated during failover. Aruba Networks

Therefore, option B precisely describes the outcome when VLAN probing fails across the required VLANs. Option A requires L2-connected clustering. Option C describes full L2 redundancy. Option D is reversed: L3-connected operation does not provide hitless client failover and users may be deauthenticated during a gateway failure. Aruba Networking

Study Guide Topics: Gateway Clustering, VLAN Probe, L2-Connected vs. L3-Connected Clusters, AP/Client State Synchronization, Stateful Failover, High-Value Session Synchronization.

The reason is that AOS 10.x does not support clustering gateways with different versions in the same cluster profile. A cluster profile defines the configuration settings for a group of gateways that are managed by Aruba Central.

According to the Aruba documentation 2 , “You can combine 7200 Series and 7000 Series gateways in the same cluster with a maximum size of four devices with reduced AP client capacity on 7000 Series gateways.”

The correct answer is B. An event log message is created.

The do-not-disable parameter is used to prevent the switch from disabling the port when a loop is detected by the loop-protect feature. Instead, the switch will generate an event log message that indicates the port number and the VLAN ID where the loop was detected. The switch will also send a trap to the SNMP manager, if configured 1 .

The other options are incorrect because:

A. Port status will not be validated once status is cleared. The port will remain enabled even if a loop is detected, unless the loop-protect action is changed to tx-disable or tx-rx-disable 1 .

C. The network analytics engine will not be triggered by a loop detection. The network analytics engine is a feature that allows users to monitor and troubleshoot network issues using scripts and agents 2 .

D. Port status LED will not blink in amber with 100Hz. The port status LED will indicate the normal port status, such as link speed and activity, regardless of the loop detection 3 .

The best option to enhance security for the new IP cameras and scanners in this environment is C. MPSK provides for each device in the WLAN to have its own unique pre-shared key.

MPSK stands for Multi Pre-Shared Key, and it is a feature that allows different devices to connect to the same SSID with different pre-shared keys. This improves the security and scalability of the network, as each device can have its own key and role without requiring 802.1X authentication or an external policy engine. MPSK can be configured either locally on the AP or centrally on Aruba Central 1 2 .

The other options are incorrect because:

A. MPSK Local is a feature that allows the user to configure 24 PSKs per SSID locally on the device. These local PSKs would serve as an extension of the base MPSK functionality. However, MPSK Local is not suitable for this scenario, as it can only support up to 24 devices per SSID, while the client has 250 devices 1 .

B. Aruba ClearPass is a network access control solution that can perform 802.1X authentication and install certificates for devices. However, this option is not feasible for this scenario, as the new IP cameras and scanners do not support 802.1X authentication 3 .

D. MPSK Local will not allow the cameras to share a key and the scanners to share a different key. MPSK Local will assign a different key to each device, regardless of their type. Moreover, MPSK Local can only support up to 24 devices per SSID, while the client has 250 devices 1 .

This is the correct explanation of how roles can help keep consistent policy enforcement in a distributed overlay fabric. Roles are used to assign group based policy IDs (GBPs) to devices after they authenticate with ClearPass or a local database. GBPs are then used to tag the traffic from the devices and send them to the ingress VTEP, which applies the GBP on the VXLAN header. The egress VTEP then enforces the policy based on the GBP and the destination device. The other options are incorrect because they either do not describe the correct sequence of events or do not use the correct terms.

To onboard a new UXI in an existing environment with 802.1X authentication, you need to use the UXI app on your smartphone and connect the UXI via Bluetooth. The UXI app allows you to scan the QR code on the UXI sensor and configure its network settings, such as SSID, password, IP address, etc. The Bluetooth connection allows you to communicate with the UXI sensor without requiring any network access or cellular connection. The other options are incorrect because they either do not use the UXI app or do not use Bluetooth.

The capability that enables plug-and-play provisioning of access points in an HPE Aruba network is the UCC Service. The UCC Service is a cloud-based service that allows the access points to automatically discover and connect to the Aruba Central management platform without any manual intervention. The UCC Service also provides zero-touch configuration, firmware updates, and monitoring for the access points 1 .

The other options are incorrect because:

B. LLDP-MED: LLDP-MED is a protocol that enhances the interoperability between network devices and IP phones. It does not enable plug-and-play provisioning of access points 2 .

C. SRTP: SRTP is a protocol that provides encryption and authentication for voice and video traffic. It does not enable plug-and-play provisioning of access points 3 .

D. CSMA: CSMA is a protocol that regulates how devices share a common medium, such as a wireless channel. It does not enable plug-and-play provisioning of access points.

Policy Manager uses Group Policy Identifier (GPID) to carry policy information in traffic for in-line enforcement. Policy Manager also integrates with Cloud Auth, ClearPass, or third-party solutions to provide flexible network access control.

The correct answers are C and D.

MPSK (Multi Pre-Shared Key) is a feature that allows multiple PSKs to be used on a single SSID, providing device-specific or group-specific passphrases for enhanced security and deployment flexibility for headless IoT devices 1 . MPSK requires MAC authentication against a ClearPass Policy Manager server, which returns the encrypted passphrase for the device in a RADIUS VSA 2 . ClearPass Policy Manager is a platform that provides role- and device-based network access control for any user across any wired, wireless and VPN infrastructure 3 . ClearPass Policy Manager can also use device profiling and posture assessment to assign roles based on device fingerprint information 4 .

MPSK Local is a variant of MPSK that allows the user to configure up to 24 PSKs per SSID locally on the device, without requiring ClearPass Policy Manager 5 . MPSK Local can be combined with EAP-TLS (Extensible Authentication Protocol-Transport Layer Security), which is a secure authentication method that uses certificates to encrypt the wireless traffic between the IoT devices and the access points 6 . EAP-TLS can also use device certificates to perform role-based access control 6 .

Therefore, both ClearPass Policy Manager and MPSK Local with EAP-TLS can meet the customer’s requirements for wireless authentication, encryption, unique passphrase, and role-based access for their IoT devices.

MPSK and an internal RADIUS server is not a valid solution, because MPSK does not support internal RADIUS servers and requires ClearPass Policy Manager 7 8 9 . MPSK Local with MAC Authentication is not a valid solution, because MAC Authentication does not encrypt the wireless traffic or use fingerprint information for role-based access 2 . Local User Derivation Rules are not a valid solution, because they do not provide unique passphrase per device or use fingerprint information for role-based access 10 11 12 .

This is the appropriate solution for this scenario where wireless 802.1X authentication will be against a RADIUS server in the cloud and the security team is concerned that the traffic between the AP and the RADIUS server will be exposed. RadSec, also known as RADIUS over TLS, is a protocol that provides encryption and authentication for RADIUS traffic over TCP and TLS. RadSec can be configured on both the AP and the RADIUS server to establish a secure tunnel for exchanging RADIUS packets. The other options are incorrect because they either do not provide encryption or authentication for RADIUS traffic or do not involve RadSec.

The persona role option that should be selected to deploy a Gateway and take advantage of all the SD-WAN features is A. ArubaOS 10 Branch.

ArubaOS 10 Branch is a persona that enables the Gateway to provide both LAN and WAN functionality for branch networks. The Gateway can act as a wireless controller, a router, a firewall, and an SD-WAN device. The SD-WAN features include route and tunnel orchestration, dynamic path steering, forward error correction, SaaS traffic optimization, SASE orchestration, and more 1 .

The other options are incorrect because:

B. ArubaOS 10 VPN Concentrator: This is a persona that enables the Gateway to act as a VPN concentrator for remote access or site-to-site VPN connections. It does not provide SD-WAN features 2 .

C. ArubaOS 10 Wireless: This is a persona that enables the Gateway to act as a wireless controller for campus networks. It does not provide SD-WAN features 3 .

D. ArubaOS 10 Mobility: This is a persona that enables the Gateway to act as a mobility controller for campus networks. It does not provide SD-WAN features.

The likely cause of the issue of weak Wi-Fi coverage in the office is that the AP is using a directional antenna. A directional antenna is an antenna that radiates or receives radio waves more strongly in one or more directions, creating a focused beam of signal. A directional antenna can provide better coverage and performance for a specific area, but it can also create dead zones or weak spots for other areas. The other options are incorrect because they either do not affect the Wi-Fi coverage or do not match the scenario.

This is the best practice for handling voice traffic with dynamic segmentation on AOS-CX switches. Dynamic segmentation is a feature that allows AOS-CX switches to tunnel user traffic to a controller or another switch based on user roles and policies. For voice traffic, it is recommended to use switch authentication and local forwarding, which means the voice devices are authenticated by the switch and their traffic is forwarded locally without tunneling. This reduces latency and jitter for voice traffic and improves voice quality. The other options are incorrect because they either use central authentication or tunneling, which are not optimal for voice traffic.

MPSK Local is a feature that can be used to set up 15 headless IoT devices that do not support 802.1X authentication. MPSK Local allows the switch to automatically generate and assign unique pre-shared keys for devices based on their MAC addresses, without requiring any configuration on the devices or an external authentication server. The other options are incorrect because they either require 802.1X authentication, which is not supported by the IoT devices, or WPA3 encryption, which is not supported by Aruba CX switches.

Splitting a larger OSPF area into a number of smaller areas has several advantages for network scalability and performance. Some of these advantages are:

It increases stability by limiting the impact of topology changes within an area. When a link or router fails in an area, only routers within that area need to run the SPF algorithm and update their routing tables. Routers in other areas are not affected by the change and do not need to recalculate their routes.

It reduces processing overhead by reducing the size and frequency of link-state advertisements (LSAs). LSAs are packets that contain information about the network topology and are flooded within an area. By dividing a network into smaller areas, each area has fewer LSAs to generate, store, and process, which saves CPU and memory resources on routers.

It reduces bandwidth consumption by reducing the amount of routing information exchanged between areas. Routers that connect different areas, called area border routers (ABRs), summarize the routing information from one area into a single LSA and advertise it to another area. This reduces the number of LSAs that need to be transmitted across area boundaries and saves network bandwidth.
