   A VxRail cluster has 6 nodes of model E560 with 10GbE networking. The administrator needs to add 2 nodes to increase capacity. The only available nodes are model E660 with 25GbE networking. The compatibility matrix confirms that E660 nodes can be added to an E560 cluster. The administrator is concerned about the network speed mismatch. What is the best course of action?

   • AAdd the E660 nodes as-is, as VxRail Manager will automatically handle the network speed difference.
   • BCheck the network switch capabilities and the VxRail compatibility matrix for supported network configurations, then decide whether to use 10GbE or upgrade the switches.
   • CAdd the E660 nodes and configure them to use 10GbE to match the existing cluster.
   • DUpgrade the existing cluster's network to 25GbE before adding the E660 nodes.

   An administrator is expanding a VxRail cluster from 8 to 12 nodes. The administrator has already staged the new nodes and connected them to the network. The administrator runs the 'Add Node' wizard in VxRail Manager. During the pre-check phase, the wizard reports a warning about the vSAN health check. What should the administrator do next?

   • AProceed with the node addition, as warnings are informational and do not block the expansion.
   • BContinue with the wizard but select the 'Skip vSAN health check' option to avoid delays.
   • CReboot the new nodes and restart the wizard to clear the warning.
   • DCancel the wizard, investigate the vSAN health warning, and resolve any underlying issues before retrying.

   How does adding nodes to a VxRail cluster typically affect cluster performance?

   • AIt can increase overall performance by adding more compute and storage resources.
   • BIt only affects storage performance, not compute.
   • CIt has no impact on performance.
   • DIt always decreases performance due to increased overhead.

   A VxRail cluster is being expanded from 6 to 8 nodes. The administrator is concerned about the impact on cluster performance during the expansion. What is the most significant factor that can affect performance during the expansion?

   • AThe vCenter server's performance.
   • BThe network speed of the new nodes.
   • CThe number of VMs running on the cluster.
   • DThe amount of data that needs to be rebalanced across the new nodes.

   An administrator is adding 2 nodes to a VxRail cluster. The administrator has started the 'Add Node' wizard and is at the point where the wizard asks for the vCenter credentials. The administrator enters the credentials, but the wizard fails to authenticate. What is the most likely cause of this failure?

   • AThe new nodes are not powered on.
   • BThe VxRail cluster is in a maintenance mode.
   • CThe vCenter credentials are incorrect or the account does not have sufficient privileges.
   • DThe vCenter server is not reachable from the VxRail Manager.
