I disagree, I think it should be 1548 to be safe.

Wait, is it really just 1526? That seems low for GRE.

I thought it would be higher than that, but 1526 seems right.

Definitely going with 1526 for the MTU. Makes sense!

The service MTU is 1514, so we need to account for GRE overhead.

I practiced a similar question, and I think the minimum MTU should be 1526 to accommodate the GRE overhead.

I’m not entirely sure, but I feel like the answer could be 1548 since that’s a common value for GRE.

I remember something about needing to account for the GRE header, which could mean we need at least 1526.

I think the MTU for GRE encapsulation adds some overhead, so it might be higher than 1514.

The key is understanding how GRE encapsulation affects the frame size. I'll work through the math step-by-step to determine the minimum required Ethernet MTU.

I'm a bit confused. Is the answer just the service MTU plus some additional overhead, or is there more to consider here?

Okay, I've got this. The service MTU is 1514, so the Ethernet physical network MTU needs to be larger to account for the GRE encapsulation.

Hmm, this is a tricky one. I'll need to think through the layers and encapsulation to figure out the right answer.

I'm pretty confident the answer is B. The GRE encapsulation adds 24 bytes, so the minimum Ethernet MTU would be 1514 + 24 = 1538, which rounds up to 1526.

Ah, the point-to-point interface configuration on Router1 could be the key. I'll focus on that and see if changing it to the correct setting resolves the issue.

I'm a bit confused by this question. How exactly do user stories relate to the Fundamental Test Process? I'll have to review my notes on that.

E, definitely E. 1536 bytes sounds like the perfect MTU for a Layer 2 service. Why? Because it's the magic number, that's why!
