Cisco 300-515 Implementing Cisco Service Provider VPN Services (300-515 SPVI) Exam Practice Test

They add an additional tag to VLANs that allows up to two switch ports to use the same globally configured VLAN ID.

They redefine the VLAN tag to include classification, forwarding, and QoS using MPLS labels and EXP bits

They separate the classification and forwarding concepts for VLAN tagging which allows multiple switch ports to use the same VLAN ID without it being configured globally.

They assign VLAN IDs to VTP domains so that the same VLAN ID are used more than once globally.

The loopback0 interface must be in OSPF area 0.

The network statement under the routing process must have a wildcard mask of 0 0.0 255.

The OSPF network type must be changed on loopback0 to point-to-point

A static route to null 0 must be added for the loopback interface and then static routes must be redistributed into OSPF

by converting CE routes into VPNv4 routes and exchanging them using MP-BGP

by establishing BGP neighbor relationships between all connected CEs to exchange routing information

by learning IPv4 routes from connected CEs and redistributing them into the global IGP

by converting CE routes into VPNv4 routes and exchanging them using the global IGP

asymmetric mutual authentication with PSK

The STP mode must be RSTP or PVST+

Bridge domains must be mapped to a different VLAN.

The STP mode must be MSTP

Bridge domains must belong to different MST instances.

Layer 2 VPNs use IPsec tunneling, but Layer 3 VPNs use L2TPv3 tunneling.

Layer 2 VPNs use AToM, but Layer 3 VPNs use MPLS/BGP.

Layer 2 VPNs use BGP, but Layer 3 VPNs use VPLS.

Layer 2 VPNs use L2TPv3 tunneling, but Layer 3 VPNs use GRE tunneling.

Layer 2 VPNs use IPsec tunneling, but Layer 3 VPNs use pseudowires to provide tunneling.

The model is suited for nonredundant configurations.

The configuration on a newly added site PE is updated automatically.

Provider routers know the customer network topology.

The customer specifies the exact site-to-site traffic profile.

Routing information is exchanged between the customer router and one or a few PEs.

The CSC-PE and CSC-CE must each be able to ping an interface in its respective global routing table.

The CSC-PE and the CSC-CE must support IPv6.

The CSC-PE and CSC-CE devices must be able to send labels to one another using BGP.

The CSC-CE must support OSPFv3.
