I didn't realize a stateless PCE had those limitations, that's surprising!

A is definitely correct, link-state IGPs are used for that.

Wait, are you sure about D? I thought stateful PCEs just manage LSPs.

I think C is the false one. Stateless PCEs can't do that.

A stateful PCE does monitor LSPs, that's true.

I have a vague memory that a stateless PCE has limitations, so C could be the false statement, but I’m not completely confident.

I practiced a similar question where the PCE's role was highlighted, and I think option D about reserving bandwidth sounds correct.

I'm not entirely sure, but I feel like stateful PCEs are supposed to monitor LSPs, so option B might be true.

I think I remember that a stateless PCE can't handle cross-area LSPs, so maybe option C is the false one?

This looks like a tricky one. I better read through the options carefully and think about the PCE functionality to nail down the right answer.

I think the key here is understanding the capabilities of stateful vs. stateless PCEs. I'll review my notes on that to identify the false statement.

Okay, let me see. The PCE can get topology and TE info from IGP or BGP-LS, that sounds right. And a stateful PCE does monitor LSPs and trigger repairs. But I'm not sure about the stateless PCE and cross-area TE paths.

Hmm, I'm a bit unsure about the differences between stateful and stateless PCEs. I'll need to think this through carefully.

I think using AWS Glue and Athena might require the least effort since Athena can query data directly in S3 without any heavy transformations.

Hmm, this seems like a tricky one. I'll need to carefully review the details about the Azure Cosmos DB and Azure Functions setup to determine the right property to change.

Hmm, I'm not totally sure about this one. I know a prima facie case is when the evidence seems to support the claim on the surface, but I'm not confident that's the right answer here. I'll have to think it through carefully.
