An administrator is asked to segregate virtual machine (VM) traffic by VLAN on a vSphere standard switch The following requirements must be met:

* VLAN ID on the switch port group must be 4095.

* VLAN tagging must be done at the VM level.

Which tagging mode is required?

Show Suggested Answer Hide Answer
Suggested Answer: C

The tagging mode that is required is Virtual Guest Tagging (VGT), which allows VLAN tagging to be done at the VM level. VGT requires that the VLAN ID on the switch port group be set to 4095, which is a special value that indicates that packets from all VLANs are allowed to pass through.

Candidate 3: I think both of you are wrong, the correct tagging mode is A) External Switch Tagging (EST) because the VLAN ID on the switch port group must be 4095.

I'm not sure, but I think External Switch Tagging (EST) could also be a valid option.
