Question #: 92
Topic #: 4

A school uses the POL networking and has only one campus. During VLAN design, VLANs are divided by service type and services are identified by a single VLAN tag. In this case, which VLAN attribute should be used?

ACommon

BQinQ

CSub

DStacking

Show Suggested Answer

Suggested Answer: A

VLAN Attributes :

Common VLAN : Used for standard VLAN tagging, where a single VLAN tag identifies the VLAN.

QinQ VLAN : Adds an additional VLAN tag for double-tagging, typically used in carrier networks.

Sub VLAN : Part of a Super VLAN configuration, used for IP address conservation.

Stacking VLAN : Similar to QinQ, used for double-tagging.

Scenario Analysis :

The school uses a single VLAN tag to identify services by type (e.g., student, faculty, administration).

Since only one VLAN tag is used, the appropriate VLAN attribute is Common .

Why A?

Common VLAN is the simplest and most suitable choice for scenarios requiring single-tag VLAN identification.

Thus, the correct answer is A .

Dude, this question is giving me flashbacks to my networking class. Definitely gotta go with C. Sub, unless the professors are trying to trick us. Hmm, maybe I should just ask Siri for the answer.

I'm not sure, but I think the answer might be C) Sub because it divides VLANs by service type.

Ah, the classic VLAN tag dilemma. I bet the answer is A. Common, because that's the most generic option, right? Wait, did I read the question correctly?
