An ESXi 5.x host disconnects within 60 seconds after the administrator adds it to the vCenter Server inventory. The administrator determines that the issue could be related to a networking problem.
Which networking port should the administrator check for connectivity from the host to vCenter Server?
A. 902
B. 903
C. 443
D. 9443
Correct Answer: A
Explanation/Reference:
Explanation:
A: Port 902 is the port that vCenter Server assumes is available for receiving data from ESXi. It is the port that the vSphere Client assumes is available when interacting with virtual machines. The vCenter server uses this port to send data to the ESXI servers it manages. The listening process (vmwareauthd) on the ESXI server handles the flow of traffic.
Incorrect Answers:
B: The vSphere Client uses Port 903 to provide a connection for guest operating system MKS (mouse, keyboard, screen) activities on virtual machines. Port 903 connects the vSphere Client to a specified virtual machine configured on ESXi.
C: The vSphere Client and (software development Kit) SDK use Port 443 to send data to vCenter Server managed hosts. Port 443 is the port that clients assume is available when sending data to ESXi. VMware does not support configuring a different port for these connections.
D: Port 9443 is the default port tht is used when enabling VSA Access for the vSphere Web Client.
