I believe intermediate routers follow the best IGP path, not just any path.

Definitely, a tunnel can use both Node-SIDs and Adjacency-SIDs.

Wait, can a tunnel really be defined by multiple Node-SIDs? That’s new to me!

I disagree, I think it can vary based on the configuration.

A Segment Routing tunnel defined by a Node-SID does use the shortest IGP path.

I’m a bit confused about Adjacency-SIDs and Node-SIDs; I think they can work together, so option C might be correct.

I feel like option D could be the false statement since I recall something about intermediate routers not always following the best IGP path.
BE

I think I saw a practice question that mentioned multiple Node-SIDs can define a tunnel, so maybe option B is true?
MA

I remember studying that Node-SIDs are used for defining paths, but I'm not sure if they always use the shortest IGP path.

I've got a good handle on Segment Routing, so I'm feeling confident about this one. I'll just need to double-check my understanding of the details.

I'm a little confused by the wording of the question. I'll need to read it a few times to make sure I understand what they're asking.

Okay, let me break this down step-by-step. I think the key is understanding how Segment Routing tunnels work and the role of the different SID types.

Hmm, I'm a bit unsure about the differences between Node-SIDs and Adjacency-SIDs. I'll need to think this through carefully.

This question seems pretty straightforward. I'm pretty confident I can figure this out.

I'm pretty sure the key data object associated with the Service Portfolio functional component is Conceptual Service, so I'll go with option B.

Option D sounds like it's trying to trick us. Of course an intermediate router would forward the packet based on the best IGP path. I'm confident that's the false statement here.

Yeah, I think so too. Option D doesn't make sense in the context of Segment Routing tunnels.

I agree, it does seem like a trick question. Let's go with option D as the false statement.

D) For a Segment Routing tunnel, an intermediate router will always forward the packet based on the best IGP path.

I'm stumped on this one. Is the answer E) All of the above are true? That's my best guess at this point.
EV

Haha, this question is a real head-scratcher. I'm going to go with C - a combination of Node-SIDs and Adjacency-SIDs sounds like the most comprehensive option.

I agree with you, C seems like the most comprehensive choice.

But D makes sense, the best IGP path should be followed.

I think C is correct too, it covers all the possibilities.

LE

I think C is correct too, it covers more possibilities.
YU

I believe the correct answer is D as well, because sometimes an intermediate router may have specific policies or constraints that affect the forwarding decision.
TR
Tracey

I agree with Chandra, because an intermediate router may not always forward based on the best IGP path.
CH
Chandra

I think the false statement is D.
MI

I think B is the correct answer. A Segment Routing tunnel can definitely be defined by multiple Node-SIDs.
CA

Option D seems off. Why would an intermediate router not forward the packet based on the best IGP path? That doesn't make sense to me.
