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 details
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.

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 details
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.

The command to export the configuration payload from the VxRail Configuration Portal is generated in which file format for import into the VxRail Manager first-run wizard?
Show answer details
Correct answer: C
The VxRail Configuration Portal generates and exports a .JSON file. This JSON payload contains all the networking, naming, and configuration settings, which can be directly imported into the VxRail Manager first-run wizard to automate the deployment.
- 4
During pre-install validation, the wizard halts with a "Duplicate IP" error. The engineer confirms that none of the target IP addresses are currently assigned to any active devices on the network.
What is a potential cause for this false positive duplicate IP error?
Show answer details
Correct answer: A
If Proxy ARP is enabled on the gateway/router interface for the management subnet, the router may respond to the ARP requests generated by the VxRail pre-install validation checks, making VxRail Manager incorrectly believe the IPs are already in use.
- 5
An implementation engineer is preparing a Top-of-Rack (ToR) switch for a new VxRail deployment. To ensure that the VxRail Manager can automatically discover the unconfigured nodes via the Loudmouth protocol, which specific networking feature must be enabled on the management VLAN?
Show answer details
Correct answer: B
VxRail uses the Loudmouth protocol for node discovery, which relies on IPv6 multicast. Therefore, IPv6 multicast traffic must be allowed on the native VLAN (or the designated management VLAN) connecting the VxRail nodes. MLD snooping or an MLD querier is often configured to manage this traffic.
- 6
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?
Show answer details
Correct answer: C
When deploying VxRail with a customer-managed (external) vCenter, a Datacenter object must exist prior to deployment. The VxRail deployment wizard will create the cluster object (or it can be pre-created, but the datacenter must exist) and the VDS during the installation process.
