Question 2

An architect is designing a VxRail solution for a customer who needs vCenter HA.

Which vCenter Server platform options supports this requirement?

Options:

A.

Use an existing VxRail-managed vCenter server

B.

Use an existing Customer-supplied vCenter server

C.

Use an existing Customer-supplied vCenter server

D.

Use a new VxRail-managed vCenter server

Question 3

Which VxRail Dynamic Node configuration supports a VxRail-managed vCenter on the local cluster?

Options:

A.

PowerMax 2000 connected via FC-NVMe

B.

PowerStore 5200T connected via NVMe/TCP

C.

PowerFlex R750 connected via SDC

D.

Unity XT 680 connected via NFS

Question 4

A VxRail architect is designing a 6-node VxRail Cluster for critical applications.

Which two combinations of fault tolerance policies ensure availability of cluster if there is a single data center failure? (Choose two.)

Options:

A.

Site disaster tolerance=None – standard cluster

Failures to tolerate=1 failure – RAID 5 (Erasure Coding)

B.

Site disaster tolerance=Site mirroring – stretched cluster

Failures to tolerate=No data redundancy

C.

Site disaster tolerance=Site mirroring – stretched cluster

Failures to tolerate=2 failures – RAID 1 (Mirroring)

D.

Site disaster tolerance=Site mirroring – stretched cluster

Failures to tolerate=2 failures – RAID 6 (Erasure Coding)

E.

Site disaster tolerance=Site mirroring – stretched cluster

Failures to tolerate=1 failure – RAID 1 (Mirroring)

Question 5

What are two requirements for automatic node discovery? (Choose two.)

Options:

A.

The switches must be configured to allow IPv6 multicast traffic.

B.

The internal management VLAN must be configured on the switches for the nodes.

C.

The switches must be configured to allow IPv4 multicast traffic.

D.

The management IP addresses must be set on the nodes.

Question 6

What are three reasons that a customer would use VxRail Dynamic nodes? (Choose three.)

Options:

A.

To use vSAN storage from an existing VxRail vSAN cluster

B.

To use existing supported storage arrays

C.

To use only vSphere Standard Switches

D.

To optimize or reduce licensing costs

E.

To use external storage in addition to local vSphere vSAN for tiering

Question 7

What are two rules for witness on a VxRail stretched cluster? (Choose two.)

Options:

A.

The Witness appliance is the same for vSAN ESA and vSAN OSA architecture.

B.

It must be the same vSphere version as the VxRail nodes.

C.

It must be deployed in advance.

D.

It can be managed by a separate vCenter than the one managing the VxRail cluster.

E.

Only a virtual appliance is supported.

Question 8

A customer is planning to expand an existing VxRail vSAN cluster. Their current rack is full, so the cluster has to expand to an additional rack. Due to networking requirements, each rack is a Layer 2 boundary, so the new nodes require new management, vSAN, and vMotion subnets.

When designing the solution, what are two considerations that the architect should consider? (Choose two.)

Options:

A.

Automatic node discovery is not supported; manual discovery must be used.

B.

VxRail Manager must remain in the first rack.

C.

vSAN ESA is not supported. Only vSAN OSA is supported.

D.

VMware Cloud Foundation is not supported.

Question 9

Which tool can be used to gather application and virtual environment workload of an existing environment?

Options:

A.

VxRail Sizer

B.

Live Optics

C.

VxRail Configuration Portal

D.

Secure Connect Gateway

Question 10

Which document from the VxRail Configuration Portal can be used to validate site readiness before a deployment?

Options:

A.

Getting Started Guide

B.

Pre-deployment Checklist

C.

Deployment Planning Guide

D.

Configuration Report

Question 11

A customer has an existing VxRail vSAN OSA cluster consisting of 5 x E660F nodes.

Which two node types can be added to that cluster? (Choose two.)

Options:

A.

E665F

B.

P670F

C.

E660N

D.

E660

Question 12

When leveraging an external DNS for a VxRail deployment, which components must have valid lookup records?

Options:

A.

VxRail Manager, vCenter Server, iDRAC

B.

ESXi hosts, vSAN addresses, vCenter Server

C.

vCenter Server, VxRail Manager, ESXi hosts

D.

vCenter Server, ESXi hosts, discovery addresses
