Question 1

A customer requires their new VxRail cluster to be deployed using an existing, customer-managed vCenter Server. The implementation specialist is validating the prerequisites on the external vCenter.

Which logical object must already exist in the customer-managed vCenter before initiating the VxRail first-run deployment?

Accepted Answer

A Datacenter object with a unique name

Answer

An empty Resource Pool

Answer

A placeholder vSAN datastore

Answer

A pre-configured Distributed Virtual Switch (VDS)

Question 2

A global enterprise is planning a Layer 3 (L3) VxRail deployment across multiple racks. The architect has mapped out the subnets for Management, vSAN, and vMotion.

Reviewing the architecture, what is a mandatory requirement regarding the VxRail Manager and vCenter Server IP addressing in this topology?

```mermaid
graph TD
subgraph Rack 1
Node1[VxRail Node 1]
Node2[VxRail Node 2]
Node3[VxRail Node 3]
end
subgraph Rack 2
Node4[VxRail Node 4]
Node5[VxRail Node 5]
end
Router[L3 Router]
Node1 & Node2 & Node3 --> Router
Node4 & Node5 --> Router
```

Accepted Answer

They must be deployed in the same broadcast domain (VLAN/subnet) regardless of the L3 topology for the ESXi hosts.

Answer

They must be placed on the vSAN network to prioritize lifecycle management traffic.

Answer

They must reside on different subnets to ensure isolation between management and application traffic.

Answer

VxRail Manager must use a public IP address to communicate across the L3 boundary.

Question 3

True or False: When preparing DNS for a new VxRail deployment, both Forward (A) and Reverse (PTR) records are strictly required for the ESXi hosts, VxRail Manager, and vCenter Server.

Accepted Answer

True

Answer

False

Question 4

During the pre-deployment phase, an engineer is filling out the configuration parameters. Which TWO pieces of information must be provided specifically for the vSAN network? (Select TWO)

Accepted Answer

Starting IP Address

Accepted Answer

VLAN ID

Answer

Hostname prefix

Answer

Default Gateway

Answer

NTP Server IP

Question 5

A deployment engineer runs the pre-install validation tool on a VxRail Manager before starting the build. The tool reports an error regarding MTU mismatch.

What is the most common cause of this specific validation failure?

Accepted Answer

Jumbo frames (MTU 9000) are configured in the VxRail JSON but the ToR switch ports are set to MTU 1500.

Answer

The Loudmouth protocol is dropping packets larger than 9000 bytes.

Answer

The VxRail nodes have older firmware that only supports standard frames (1500).

Answer

The vCenter Server is deployed on a network that does not support Jumbo Frames.

Question 6

When planning IP addresses for a standard 4-node VxRail cluster using an internally deployed vCenter Server, how many IP addresses MUST be allocated for the Management network, excluding the network gateway and broadcast addresses?
