Discuss Nokia 4A0-C02 Exam Topic 1 Question 59

When deploying an Alcatel-Lucent MPLS network with QoS, how are the EXP bits set?

AThe first 3 bits of the DSCP value are copied directly into the EXP field on the first network egress.

BThe EXP bits are set on the first network egress, based on a combination of the SAP-ingress classification and the network policy applied.

CThe 3 priority bits are copied directly from the dot1p header into the EXP field of the first MPLS header.

DThe EXP bits are set based on a default map that translates DSCP codes into internal forwarding classes on SAP-ingress.

Suggested Answer: A, B

D seems a bit off to me. Default maps can be tricky.

I always thought it was A, but I guess I need to double-check!

Wait, are you sure about that? I thought it was C.

Definitely B! Makes the most sense with QoS.

I think the EXP bits are set based on the SAP-ingress classification.

I have a vague memory of a default mapping for DSCP codes, but I can't remember if that's the main method for setting EXP bits in this context.

I practiced a question similar to this where the dot1p header was mentioned, and I feel like that might be relevant here too.

I think the EXP bits are set based on the ingress classification, but I can't recall the specifics of how the network policy plays into that.

I remember something about the DSCP values and how they relate to EXP bits, but I'm not sure if they get copied directly or if there's a mapping involved.

Hmm, this is a tricky one. I need to carefully analyze each option and think about how the lack of negative testing could lead to those symptoms. I'll make sure to choose the three most relevant ones.

This seems like a straightforward question about measuring the return on investment for the company's social media marketing efforts. I'll focus on identifying the key metrics they're trying to calculate.

This seems like a straightforward question. Configuring the firewall on storage1 to only accept connections from Vnet1 should meet the goal of allowing VM1 to access storage1 while preventing it from accessing the other storage accounts.

Removing attention sounds like it could be effective, but isn't that more about reinforcement than punishment? Just trying to connect the dots here.
