An administrator is in the process of deploying a new ESXi host.

-The host is able to be added to the vCenter Server-s inventory, but after a short period of time it shows as disconnected.

-The administrator is able to reconnect the

host but it then disconnects again after a short period of time.

Which is the problem?

A. Port 902 UDP from the host to the vCenter Server is blocked

B. Port 443 TCP from the host to the vCenter Server is blocked

C. Port 902 TCP from the host to the vCen

ter Server is blocked

D. Port 443 TCP from the vCenter Server to the host is blocked

Explanation:

On 902 port managed hosts send a regular heartbeat to the vCenter Server system. This port must not be blocked by firewalls between the server and

the hosts or between hosts.
