Examine the exhibit.

Which of the following statements about the operation of EVPN VPWS 4 is FALSE?

APEI brings the SAP in VPWS 4 operationally down.

BPE3 sets the P flag in its advertised A-D per EVI route to I.

CPE2 receives a single A-D per EVI route. The route is originated from PE3.

DPE2 receives two A-D per ES routes: one from PEI and another from PE3.

Suggested Answer: B

PE3 does not set the P flag in its advertised A-D per EVI route to 1. PE3 sets the P flag to 0, indicating that it is not the DF for EVI 20.PE1 sets the P flag to 1, indicating that it is the DF for EVI 201.

C seems right too, PE2 gets that route from PE3.

Mohammad 11 months ago

B is correct, PE3 does set the P flag.

Wait, are we sure about D? Sounds off to me.

I agree, A is misleading.

A is definitely false. PEI can't bring the SAP down.

I’m leaning towards option D being false since I thought PE2 only gets one A-D per EVI route, not two from different PEs.

I have a vague recollection that PE2 only receives one A-D per EVI route from PE3, but I could be mixing it up with another scenario.

This question feels similar to one we practiced where PE3 advertised routes. I wonder if the P flag is really set to I in this case.

I think I remember something about PEI bringing the SAP down, but I'm not entirely sure if that's the right answer here.

Hmm, I'm a bit unsure about this one. I know Azure AD is a cloud-based identity service, but I'm not familiar with SAP Cloud Platform and how it integrates with Azure AD. I'll need to review my notes on identity management across different cloud platforms.

If I recall correctly, private blockchains focus on permissioned access, which makes it an interesting fit for routing attacks, although I need to double-check that.

This seems like a straightforward question about the supported log formats. I'll go with the most common option, which is JSON.
