Why would PE-B need a different SAP id?

Option A looks correct based on VLAN IDs.

Wait, are you sure about that? Seems a bit off.

Totally agree, that's the right setup!

PE-A needs 'sap 1/1/1:200' and PE-B needs 'sap 1/1/1:300' for VLANs.

I feel like option D could work too since it uses a wildcard, but I don't recall if that’s valid for direct communication between different VLANs.

I'm a bit lost on this one. I thought the SAP IDs could be generic, but now I'm questioning if they need to specify the VLANs.

I remember practicing a question like this where the SAP IDs were tied to specific VLANs. A seems to fit that pattern.
RE

I think the SAP IDs need to include the VLAN tags, so maybe A is the right choice? But I'm not entirely sure.

This is a good test of my understanding of VLAN and SAP configuration. I think option A is the correct answer, but I'll double-check the details to make sure I'm not missing anything.

I'm not entirely sure about this one. The VLAN IDs and SAP IDs seem to be related, but I'm not sure I fully understand how they need to be configured. I'll have to review the material on VLAN and SAP configuration again before answering.

Okay, I think I've got this. The key is that CE-A is on VLAN 200 and CE-B is on VLAN 300, so the SAP IDs on PE-A and PE-B need to match those VLAN IDs. I'm pretty confident option A is the right answer.

Hmm, I'm a bit confused by the different VLAN IDs and how they need to be mapped to the SAP IDs. I'll have to re-read the question and think through the options carefully.

This looks like a tricky VLAN configuration question. I'll need to carefully consider the VLAN IDs and how they relate to the SAP IDs.

I'm going with option C. It's always good to keep things simple, and 'sap 1/1/1:0' sounds like a nice, clean configuration.
KI

Option C does sound simple, but we should double-check if it will allow direct communication between CE-A and CE-B.

I'm not sure about option A. Maybe we should consider the other options before making a decision.

I agree with you, option A seems to be the most logical choice for configuring the SAP ids.
RE

I think option A is the correct one. We need to match the VLAN numbers for direct communication.

Wait, what's a SAP ID again? Is this some kind of secret Sith Lord code we need to know? *chuckles*

B) PE-A will require a SAP id of \'sap 1/1/1\' and PE-B will require a SAP id of \'sap 1/1/1\'.

It's not a secret code, SAP ID stands for Service Access Point Identifier.

A) PE-A will require a SAP id of \'sap 1/1/1:200\' and PE-B will require a SAP id of \'sap 1/1/1:300.

But A makes more sense because it specifies the VLANs for direct communication.
AN

I disagree, I believe the answer is C.
DE

I think option D is the correct answer. Using a wildcard SAP ID like 'sap 1/1/1:*' would allow communication between any VLANs on the PE devices.

I see your point, it's all about balancing flexibility and security.

That's true, but using a wildcard could simplify future configurations.
RO

But wouldn't it be safer to specify the VLANs like in option A?
RO

I agree, option D seems like the most flexible choice.
JE

I think the answer is A.
ME

Option A seems logical since the question states that CE-A is on VLAN 200 and CE-B is on VLAN 300. The SAP IDs should match the respective VLANs.
KE

Yes, PE-A needs to have a SAP ID for VLAN 200 and PE-B needs a SAP ID for VLAN 300 to allow direct communication.
KE

Option A is correct. The SAP IDs should match the VLANs of CE-A and CE-B.
