   A VCF administrator is troubleshooting an ESXi host that is not appearing in vCenter Server's inventory. The host is reachable via SSH, and the vpxa service is running. The administrator checks the vpxa log and finds repeated 'SSL certificate verification failed' errors. The host's SSL certificate was recently replaced by a third-party CA. What is the most likely cause of the host not appearing in vCenter Server?

   • AThe host's clock is out of sync with vCenter Server, causing authentication failures.
   • BThe host's management network is misconfigured, preventing communication with vCenter Server.
   • CThe vpxa service is not configured with the correct vCenter Server address.
   • DThe third-party CA certificate is not trusted by vCenter Server.

   A VCF administrator is troubleshooting an ESXi host that is failing to connect to vCenter Server. The host is reachable via SSH, and the vpxa service is running. The administrator reviews the vpxa log and finds repeated 'Connection refused' errors when trying to connect to the vCenter Server on port 443. What is the most likely cause of the connection failure?

   • AThe vCenter Server service is not running or is not listening on port 443.
   • BThe host's SSL certificate is not trusted by vCenter Server.
   • CThe host's management network is misconfigured, preventing communication with vCenter Server.
   • DThe vpxa service is not configured with the correct vCenter Server address.

   A VCF administrator is investigating why an ESXi host is not conforming to the workload domain's standard network configuration. The host's vSwitch0 has a different number of uplinks than the other hosts in the cluster. What is the most likely cause of this configuration drift?

   • AThe host's storage configuration is incorrect, causing the network configuration to be applied incorrectly.
   • BThe host's CPU is overloaded, preventing the configuration from being applied.
   • CThe host's vpxa service is not running, preventing it from receiving the standard configuration.
   • DThe host was manually reconfigured outside of the VCF lifecycle management tools.

   An ESXi host in a VCF workload domain has lost connectivity to vCenter Server, but VMs on the host are still accessible via the network. The host can be pinged from the management network. The vmkernel log shows no errors. Which configuration should be verified first to diagnose the management connectivity issue?

   • AVerify that the management VMkernel adapter is configured on the correct VLAN and has a valid IP address.
   • BReview the hostd log for authentication failures with vCenter Server.
   • CCheck the physical switch ports for errors or administrative shutdown.
   • DVerify that the vpxa service is running and configured with the correct vCenter Server address.

   An ESXi host in a VCF workload domain is showing as 'Not Responding' in vCenter Server. The host's management network is reachable via ping, and the host can be accessed directly via the DCUI. The vpxa service is running, but the hostd service is not responding to requests. Which troubleshooting step should be performed first to restore the host to a managed state?

   • AReboot the ESXi host from the DCUI to force a full restart of all management agents.
   • BCheck the vmkernel log for storage timeouts that may have caused hostd to become unresponsive.
   • CReinstall the ESXi host using the VCF lifecycle management tools to restore the management agents.
   • DRestart the hostd service from the DCUI and verify that vpxa reconnects to vCenter Server.
