[All 2V0-21.23 Questions]

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.

4095? That sounds a bit off...

No way, it’s gotta be VGT!

Definitely VGT for VM-level tagging!

VLAN ID 4095 means all VLANs, right?

I’m a bit confused about the options. I thought EST was for external tagging, but since the question says tagging is at the VM level, I lean towards VGT.

I think the answer could be VGT because it specifically mentions tagging at the VM level. But what if there's something I'm missing about the switch configuration?

I feel like I saw a similar question in our practice tests. If the VLAN ID is 4095, that might mean we need to use VST, but I'm not completely confident about that.

I remember studying VLAN tagging modes, but I'm not entirely sure which one applies here. I think it might be VGT since the tagging is done at the VM level.

I'm not sure about this one. The VLAN ID of 4095 is throwing me off. I'll need to review the concepts of VLAN tagging and see if I can figure out the right approach.

I've got this! The requirements clearly state that VLAN tagging must be done at the VM level, so the answer has to be Virtual Guest Tagging (VGT).

Hmm, I'm a bit confused. The question says the VLAN ID must be 4095, but that's not a standard VLAN ID. I'll need to double-check the details.

Okay, the VLAN ID on the switch port group must be 4095, and VLAN tagging must be done at the VM level. I think Virtual Guest Tagging (VGT) is the way to go here.

Okay, let's see. We need to allow administrators to access the session hosts, and they have private IP addresses, so we'll need some kind of intermediary service.

I'm feeling confident about this one. The client-side scripting API is the GlideUser object, so I'll go with option B.

Wait, I'm a little confused. Does this mean all current cryptography is at risk from quantum computers? I'm not sure if that's the case - I think there are other mathematical problems that are still hard for quantum computers to solve. I'll have to review this more closely.

Candidate 1: I think we have reached a consensus then. A) External Switch Tagging (EST) is the required tagging mode for segregating VM traffic by VLAN on a vSphere standard switch.
