AS 65540 routers are iBGP fully-meshed. Prefixes advertised by router R2 have a local preference of 200. Router R1 advertises the prefix 192.168.1.0/27 to routers R2 and R3. Assuming that router R3 is configured with "advertise-external", what is the expected output of "show router bgp routes" when executed on router R4?

Not sure about that, seems off to me.

I think Option A is more likely, but who knows!

Wait, R3 is set to "advertise-external"? That's interesting.

Definitely going with Option B!

R2 has a local preference of 200, so that matters.

I’m a bit confused about the fully-meshed iBGP setup. Does that mean R4 will see both prefixes from R2 and R3?

I think the local preference of 200 from R2 should influence R4's view, but I can't recall if R3's configuration changes anything significant.

I remember something about local preference affecting route selection, but I'm not sure how it plays out with iBGP.

This question feels similar to one we practiced where R1 advertised a prefix to multiple routers. I think I need to focus on how R3's "advertise-external" impacts R4.

This is a great question! I think the key benefit of organizing code into modules is that it enables the reuse of code, which can save a lot of time and effort.
