Refer to the exhibit.
Traffic corresponding to a layer-3 VPN arrives at router PE1 marked with a dot1p value of 4. The SDP carrying the traffic uses an MPLS transport tunnel. Given the policies applied on the routers in the diagram, what is the EXP value of packets arriving at router PE2?

Just to clarify, the SDP is using MPLS, right?

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

Definitely going with option B, seems right to me!

I think it should be 5 based on the policies.

The dot1p value of 4 usually maps to EXP value 3.

If I recall correctly, the dot1p value of 4 usually maps to an EXP value of 5 in MPLS. I hope that’s right!

I’m a bit confused about the policies applied on the routers. Did we cover how those affect the EXP value? I hope I remember correctly.

I think we practiced a similar question where we had to determine the EXP value based on the incoming dot1p. I feel like it might be 3, but I could be mixing it up.

I remember something about dot1p values and how they map to EXP values, but I'm not entirely sure how that translates in this scenario.

I've got a strategy for this. Since the traffic is using an MPLS transport tunnel, the EXP value will be derived from the dot1p value based on the policies configured on the routers. I just need to carefully analyze the information provided.

I'm a bit confused on the relationship between the dot1p value and the EXP value. I'll need to review my notes on how MPLS header fields are mapped to ensure I understand the right approach.

Okay, let me think this through step-by-step. The traffic arrives at PE1 with a dot1p value of 4, and the SDP uses an MPLS transport tunnel. I'll need to figure out how the EXP value is set based on that information.

Hmm, this looks like a tricky one. I'll need to carefully review the information about the layer-3 VPN, MPLS transport tunnel, and the policies applied on the routers.

Ah, I think I see it now. The dot1p value of 4 will map to an EXP value of 3 based on the policies. I'm confident I can work through this step-by-step and arrive at the correct answer.

Okay, let's see. I'm pretty sure the ACCS SGM Management Client would be one of the tools, since it's directly related to the ACCS system. But I'm not sure about the other two.

I think the Nominal Group Technique is mostly about helping a group reach consensus, but I might be mixing it up with another method.

Okay, let me think this through. VRRP advertisements are used for redundancy, so they're probably sent from both the master and standby routers to ensure the backup is ready to take over. And they definitely include timer and priority info to coordinate the failover process.

I'm a bit confused by the difference between the HTDS SOAP and custom SOAP options. I'll need to research those approaches more to understand the tradeoffs.

Okay, I've got this. CL Foods is targeting a wide range of locations and customer groups, so that points to an undifferentiated or broad-based strategy. I'll go with option B.

Wish we had more details in the question. I'm between 2 and 3. Leaning towards 2.

Not so sure, but 5 looks probable given typical QoS mappings.

I feel confident about option D, 6. The transport tunnel might be remapping values.
SY
Sylvia

Nah, I read somewhere that it should be 2 because of the MPLS classification policy.
KE
Kerry

I think it's 3. The dot1p of 4 should be mapped directly to EXP.

This question seems tricky. Any thoughts on the EXP value arriving at PE2?
