   A systems engineer is preparing to deploy a new 4-node VxRail cluster. The engineer has a spreadsheet with each node's iDRAC IP, service tag, and root credentials, but the nodes have not yet been connected to the management network. The engineer wants to populate the node list in VxRail Manager before racking the servers. Which approach should the engineer use?

   • AManually enter only the service tags, then let VxRail Manager query the nodes after they are racked.
   • BUse automated discovery with the VxRail Discovery Tool, pointing it at the management subnet.
   • CUse automated discovery with the VxRail Discovery Tool, pointing it at the iDRAC subnet.
   • DManually enter each node's iDRAC IP, service tag, and credentials into the VxRail deployment wizard.

   After manually entering node details in the VxRail deployment wizard, the administrator sees that one node is listed with a 'Not Ready' status. The other nodes show 'Ready'. What should the administrator do to resolve the issue?

   • AIgnore the status and proceed with deployment, as the node will be configured during the deployment process.
   • BRemove the node from the list and add it again with a different service tag.
   • CReboot the node and immediately rerun the validation.
   • DReview the node's validation errors, which may indicate a firmware or hardware compatibility issue.

   After manual node entry, the VxRail deployment wizard shows that one node has a 'Validation Failed' status. The error message indicates that the node's firmware is not compatible. What is the appropriate next step?

   • AReboot the node and re-run validation.
   • BProceed with deployment, as the firmware will be updated automatically.
   • CUpdate the node's firmware to a supported version and re-run validation.
   • DRemove the node and add it again with different credentials.

   A VxRail architect is planning a deployment where the management network uses a dedicated VLAN for iDRAC traffic. The nodes will be connected to this VLAN. The architect wants to use automated discovery. What must be true for automated discovery to succeed?

   • AThe nodes must have static IP addresses on the iDRAC VLAN.
   • BThe VxRail Discovery Tool must be able to reach the iDRAC VLAN.
   • CThe iDRAC VLAN must be the same as the vMotion VLAN.
   • DThe nodes must be on the same subnet as the VxRail Manager.
