Huawei H35-210_V2.5 Exam - Topic 4 Question 92 Discussion

Actual exam question for Huawei's H35-210_V2.5 exam

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 .

Wait, why would you use Stacking for this? Seems off.

Sub VLANs? Really? That doesn't sound right at all.

I think QinQ could work too, but not sure it's necessary.

Common VLANs are usually the way to go for service types.

"Stacking" doesn't seem to apply here since we're only dealing with one campus and one VLAN tag. I think it's between "Common" and "Sub."

I practiced a similar question about VLAN tagging, and I think "Sub" could be relevant since it deals with subnets, but I'm not completely confident.

I feel like "QinQ" is more about stacking VLANs, but this question seems to focus on a single VLAN tag. Maybe it's not the right choice?

I remember studying VLAN attributes, but I'm not entirely sure which one fits best here. I think "Common" might be related to standard VLANs?

The key here is that the services are identified by a single VLAN tag, so I believe the correct answer is Sub.

I'm a bit confused on this one. Is QinQ the right approach for a single campus network with service-based VLANs?

Okay, I think I know the answer here. The VLAN attribute we need is Sub, since the services are identified by a single VLAN tag.

Hmm, this seems like a tricky VLAN design question. I'll need to think through the details carefully.

Ah, the joys of VLAN design. I'm feeling like a true network wizard today, so I'm gonna go with B. QinQ. Who needs sub-VLANs when you can just stack 'em up, am I right?

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.

Let's go with C. Sub then. It seems like the most appropriate VLAN attribute for this scenario.

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?
