   In a VxRail cluster, what is the primary role of the top-of-rack (ToR) switches?

   • ATo provide power distribution to the VxRail nodes and other rack-mounted equipment
   • BTo provide out-of-band management access to the VxRail nodes' iDRAC ports
   • CTo provide the physical network connectivity between the VxRail nodes and the rest of the data center network
   • DTo manage the VxRail cluster's virtual machines and storage resources

   What is the role of the network interface card (NIC) in a VxRail node?

   • ATo provide the physical connection between the node and the network switches
   • BTo provide power to the node and other components
   • CTo process and execute virtual machine instructions
   • DTo store virtual machine data and provide storage capacity

   A VxRail cluster is being deployed in a data center with two ToR switches that are not stacked. The customer requires that the cluster can tolerate a failure of one ToR switch without any downtime. The network administrator proposes using STP with PortFast and BPDU guard on all node-facing ports. Will this meet the requirement?

   • ANo, because STP blocks one of the redundant paths, and failover may not be seamless.
   • BYes, because STP will automatically reroute traffic to the other switch in the event of a failure.
   • CNo, because STP is not supported in VxRail environments.
   • DYes, because PortFast and BPDU guard will speed up STP convergence to less than a second.

   What is the purpose of configuring link aggregation (LAG) on the ToR switches for a VxRail cluster?

   • ATo segment the network into multiple broadcast domains
   • BTo provide a single point of management for all switches
   • CTo enable Spanning Tree Protocol to prevent loops
   • DTo combine multiple physical links into a single logical link, increasing bandwidth and providing redundancy
