vCenter reports a connectivity problem with a ESXi 5.x host that is not a member of a cluster. An administrator attempts to connect directly to the host using the vSphere Client but fails with the message “An unknown connection error occurred.” Virtual machines running on the host appear to be running and report no problem.
What two methods would likely resolve the issue without affecting the virtual machines? (Choose two.)
A.
Enter the service mgmt-vmware restart command from either SSH or local CLI
B.
Select Restart Management Agents in the Direct Console User Interface (DCUI)
C.
Select Reboot Host in the Direct Console User Interface (DCUI)
D.
Enter the services.sh restart command from either SSH or the local CLI
In my opionen correct answers are: A & B

This is a tricky one, the key to this question is “without affecting the virtual machines”
We all agree that B will do it, but so will both A and D…
The problem with A is that if Automatic Startup/Shutdown of virtual machines is enabled, you risk rebooting the virtual machines.
services.sh restart on the other hand restarts the inetd service, wich will in turn restart the Management Agents, without affecting the VMs.
So the correct answer is:
B & D

Nice. Thanks for the explanation. To further clarify, this article specifies using the “service mgmt-vmware restart” command may reboot the VMs.
link: kb.vmware.com/kb/1003490
To restart the management agents on an ESX host:
Log into your ESX host as root from either an SSH session or directly from the console.
Run this command:
service mgmt-vmware restart
Caution: Ensure Automatic Startup/Shutdown of virtual machines is disabled before running this command or you risk rebooting the virtual machines. For more information, see Restarting hostd (mgmt-vmware) on ESX hosts restarts hosted virtual machines where virtual machine Startup/Shutdown is enabled (1003312) and Determining whether virtual machines are configured to autostart (1000163).

The main confusion in this question is ” vCenter reports a connectivity problem with a ESXi 5.x host” not the ESX host.
service mgmt-vmware restart command exist in ESX only Ref: KB 1003490
So the correct answer is B & D
