   A VCF administrator notices that an ESXi host is not appearing in vCenter Server's inventory, but the host is reachable via SSH. The vpxa service is not running. The administrator checks the vpxa log and finds an error indicating that the service cannot connect to the vCenter Server. What is the most likely cause of this issue?

   • AThe vpxa service is configured with an incorrect vCenter Server address or credentials.
   • BThe host's management network is down, preventing vpxa from reaching vCenter Server.
   • CThe vCenter Server is in maintenance mode, preventing new hosts from connecting.
   • DThe hostd service is not running, preventing vpxa from starting.

   A VCF administrator notices that a single ESXi host in a workload domain is experiencing high latency for all VMs running on it. vCenter Server shows the host's CPU usage at 95% and memory usage at 90%, but the other hosts in the cluster are below 50% utilization. The vmkernel log shows no storage or network errors. What is the most likely cause of the performance degradation?

   • AA storage array performance issue is affecting only this host's datastores.
   • BResource contention on the host is causing CPU scheduling delays for the VMs.
   • CA network misconfiguration is causing packet loss on the host's VMkernel adapters.
   • DThe host is experiencing memory ballooning due to overcommitment in the cluster.
