Nokia 4A0-104 Exam - Topic 7 Question 72 Discussion

Actual exam question for Nokia's 4A0-104 exam

Question #: 72
Topic #: 7

A customer requests that their Layer 2 Ethernet service be configured to forward frames up to 1514 bytes. The service provider is using MPLS encapsulation and RSVP-TE fast-reroute with facilities bypass on their redundant IP/MPLS network. What is the minimum MTU setting for the network ports?

A1514

B1528

I thought it would be higher with all that encapsulation!

Nope, it's definitely 1514.

Wait, isn't it 1528 with the MPLS overhead?

Totally agree, 1514 is the standard for Ethernet frames.

The minimum MTU should be 1514 bytes.

I vaguely recall that the MTU needs to be larger than the maximum frame size to accommodate any additional headers, so maybe 1540 is the right choice?

I feel like the answer might be 1536 bytes because that includes the Ethernet frame and some overhead, but I could be mixing it up with another topic.

I practiced a similar question where we had to consider the MTU for MPLS. I think it was something like 1528 bytes, but I'm not entirely sure.

I remember that the standard Ethernet frame size is 1514 bytes, but I think we need to account for the MPLS overhead too.

I'm feeling pretty confident about this one. The key is understanding the MPLS encapsulation and how that affects the frame size. Once I've got that figured out, the rest should be straightforward.

I've got a strategy here. I'll start by calculating the maximum frame size with the MPLS overhead, then add any additional overhead from the RSVP-TE fast-reroute. That should give me the minimum MTU setting I need.

Hmm, I'm a bit confused on how the MPLS and RSVP-TE fast-reroute with facilities bypass impact the MTU. I'll need to review my notes on those technologies to make sure I understand the implications.

Okay, let me see. The customer wants to forward frames up to 1514 bytes, and the provider is using MPLS. I think the answer has to do with the overhead added by the MPLS encapsulation.

This looks like a tricky one. I'll need to think through the MPLS encapsulation and RSVP-TE fast-reroute details to figure out the minimum MTU.

I'm pretty sure Arista uses the .swix extension for EOS extensions, so I'll go with option A.

This seems like a tricky one. I'm not super familiar with the Trusted sites setting, so I'll need to do a quick review of that before answering. Hopefully, I can figure out the right solution.

Power Automate is definitely the way to go here. It's the perfect tool for creating workflows that integrate with Microsoft 365 apps. I feel pretty good about this one.

I've got this! The key is that the pattern grants authorized external services direct access to internal services. So even though it hides internal services from unauthorized consumers, it does provide that direct access for authorized ones. The answer is True.
