I always mix up those port numbers, but yeah, 4784 is right.

Nope, it's not 3784 or 5784, just 4784.

Wait, is it really 4784? I thought it was something else!

I’m pretty confident that the correct answer is A, 4784. It seems to stick in my mind from the study sessions.

I’m a bit confused; I thought it was 3784, but now I’m second-guessing myself after reviewing the material.

I remember practicing a similar question, and I believe it was also about BFD and UDP. I think the answer is A, 4784.

I think the destination port for multi-hop BFD control packets is 4784, but I’m not completely sure.

This seems like a tricky one. I'm not entirely sure what would happen if the developer forgot the Test.setMock() step, but I'm guessing it would cause the test to fail in some way. I'll need to carefully review the steps and think through the possible outcomes.

Hmm, I'm a bit unsure on this. I remember the fundamental characteristics, but I can't recall if verifiability is one of them or if that's an enhancing characteristic. Let me think this through carefully.

Hmm, this looks like a tricky one. I'll need to think carefully about the key requirements of the Reliable Messaging pattern.

I think we need to block the malware directly, so option D seems like the right choice. But I'm not entirely sure if a file policy is what we use for this.

I'm a little confused on this one. I know the FASB framework covers a lot of ground, and these qualitative characteristics can get tricky. I'm going to have to review my notes and think it through step-by-step. Hopefully I can narrow it down from there.
