Agreed, A and B seem like the right choices here.

E can't be true, there's always some protection possible.

Wait, if R2-R3 fails, how does R3 become a PLR?

Berry 1 year ago

I think B is correct, but C seems off.

Glenn 1 year ago

R1 is definitely the LSP originator.

I’m pretty confident that none of the nodes can be protected with FRR, but I should review that section again.

I feel like R3 becoming a PLR if R2-R3 fails is a possibility, but I need to double-check that concept.

Lili 1 year ago

I remember a practice question about detour paths, but I can't recall if R1-R4-R5-R2-R3 is correct for one-to-one protection.

Sheridan 1 year ago

I think R1 being the LSP originator makes sense, but I'm not sure if it also acts as a PLR.

I'm a bit confused by the wording of the question. Let me re-read it a few times to make sure I understand what they're asking.

I think the answer might be DataExtractors? They sound like they would transform input data.

Arlene 1 year ago

Hmm, this seems like a tricky one. I'll need to think carefully about the implications of changing the element ID on the NMS.

Ellen 1 year ago

Hmm, I'm not sure about this one. The options seem a bit tricky - Session Id and Connected Apps don't seem directly relevant to managing external URLs. I'll have to think this through carefully.

I'm pretty confident about this one. I think the incorrect statement is D - users can log in on any computer in the domain, not just their own machine.
