An administrator adds an ESXi 5.x host to the inventory of a vCenter Server that is configured with a vSphere Distributed Switch. The vSphere Web Client indicates that the host is not responding. The administrator determines from the command line that the vpxa agent is stopped.
What should the administrator do to resolve this issue without affecting the uptime of the virtual machines running on the host?
A. Restart the management agents in the host’s DCUI
B. Remove and re-add the host to the vCenter inventory
C. Restart the vCenter Server service
D. Type /etc/vmware/vpxa start from the ESXi command line
Correct Answer: A
Explanation/Reference:
Explanation:
A: When you run the Direct Console User Interface (DCUI) in Lockdown Mode you will be able to restart the management agents without affecting the uptime of the virtual machines because users who were logged in to the ESXi Shell before lockdown mode was enabled remain logged in and can run commands.
Incorrect Answers:
B: Removal of the host inevitably will result in downtime of the virtual machines that are running on the host.
C: Restarting the vCenter Server Service will also restart the vpxa agent as this is a part of the process of enabling the DCUI Lockdown Mode because Lockdown mode is only available on ESXi hosts that have been added to vCenter Server.
D: It is fine and well starting up the vpxa agent from the ESXi command line, but you will have to be a root user and first log into the DCUI and place it in Lockdown Mode else you will have dorntime on the virtual machines that are running on the host.
