- Question 1Select 2
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)
Show answer & explanation
Correct answers: A, B
The vSAN network requires a starting IP address (which will be incremented for each node) and a VLAN ID to segregate the storage traffic. Hostnames are not assigned to vSAN interfaces, and a Default Gateway is typically only required if routing vSAN traffic (L3), but starting IP and VLAN ID are always required.

- Question 2
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?
Show answer & explanation
Correct answer: B
An MTU mismatch during pre-install validation almost always occurs because the deployment configuration specifies Jumbo Frames (MTU 9000) for vSAN and/or vMotion, but the upstream Top-of-Rack (ToR) switch ports have not been configured to allow frames larger than the default 1500 bytes.
- Question 3
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?
Show answer & explanation
Correct answer: C
For a 4-node cluster with internal vCenter, you need 7 Management IPs: 4 for the ESXi hosts (one per node), 1 for the VxRail Manager, 1 for the vCenter Server, and 1 for the optional but highly recommended VxRail Log Insight / syslog integration (or historically, PSC if separate, but 7 is the standard baseline count for core management components).
- Question 4
During a pre-deployment network validation, the VxRail Manager reports that the NTP server is unreachable. The network engineer confirms that the IP address is correct and the NTP server is online.
Which of the following is the most likely reason for this failure?
Show answer & explanation
Correct answer: A
NTP operates over UDP port 123. If the NTP server is online and the IP is correct, a firewall blocking this specific port is the most common reason for NTP validation failure during pre-deployment.

A customer is providing a customer-managed vCenter for a new VxRail deployment. To ensure the VxRail Manager can properly configure the cluster, an account must be provided in the deployment wizard.
What minimum permission level must this account have in the customer-managed vCenter?
Show answer & explanation
Correct answer: C
For a customer-managed vCenter, the VxRail deployment requires an account with Administrator privileges applied at the Datacenter level (where the VxRail cluster will be created) and set to propagate to children. Global root access is not strictly required, but Datacenter-level admin is mandatory.
- Question 6
A deployment engineer connects to the VxRail Manager interface at 192.168.10.200 but sees no nodes listed for discovery. The hosts are powered on, and the cables are securely connected to the ToR switch.
Which switch port configuration issue is the most likely cause of this discovery failure?
Show answer & explanation
Correct answer: A
VxRail nodes send discovery traffic untagged. The ToR switch ports connecting to the nodes must be configured as trunk ports passing all required VLANs, and the management VLAN must be set as the Native (untagged) VLAN. If configured as access ports, other required VLANs (vSAN, vMotion) will fail, and discovery may fail depending on how the switch handles the untagged traffic.
