Establishing adjacencies with both R1 and R2 could work too, just saying.

I’m surprised that IGP adjacencies aren’t the go-to option. Seems risky!

Wait, why not option D? More sessions could mean better data, right?

I think option C is the best choice. BGP-LS is key for topology info.

I have a hunch that BGP-LS with R3 and R4 is the best way to gather all the necessary info, but I need to double-check my notes.

I feel like IGP adjacencies with both R1 and R2 could be a viable option, but I can't recall the specifics.

I remember a practice question where we had to establish BGP sessions for topology info, so maybe option D is the right choice here.

I think establishing IGP adjacencies is important, but I'm not sure if just R2 is enough.

I've got a good feeling about this one. Based on the exhibit, I think establishing BGP sessions using the BGP-LS address family with routers R3 and R4 is the way to go.

Okay, let's think this through. The key seems to be obtaining the necessary topology and traffic-engineering information, so I'll focus on the options that mention IGP and BGP-LS.

Hmm, I'm a bit unsure about this one. I'll need to review the concepts around PCE and IGP/BGP-LS to make sure I understand the requirements.

This looks like a tricky question. I'll need to carefully analyze the exhibit and the options to determine the best approach.

Hmm, I'm a bit unsure about this one. I know we need to configure the prerequisites, but I'm not sure if creating an Azure Service Health alert rule or enabling the Application Insights Agent are required. I'll have to double-check the documentation to be sure.

Ah, I see. This is asking about the browser options when previewing a page in a GUI HTML editor. I think I know the answer to this one, but I'll double-check the choices just to be sure.
