Sulphide stress corrosion cracking? That’s a new one for me!

I've seen leaks happen from this before, so B could be true too.

I’m leaning towards option C, but I wonder if there are any exceptions based on temperature or concentration that I missed in my notes.

I feel like sulphide stress corrosion cracking is a different mechanism, but I can't recall the specifics right now.

I remember practicing a question about stress corrosion cracking in stainless steel, and I think it involved chlorides too.

Hmm, I'm a bit confused by the wording here. I'll need to review my notes on the different types of stress corrosion cracking to figure out which one applies in this case.

Okay, let's see. R5 has a local preference of 200 on its prefixes, and R3 is advertising 192.168.1.0/27 to R5 and R6. I think I know where this is going, but I'll double-check my understanding.

Okay, let me think this through. Polygraph is definitely one type of lie detection test, but I seem to recall there are a few other options as well. I'll have to carefully consider each choice.

Okay, let me see. Role-playing is meant to simulate real-world situations, so I'm guessing the answer is A. It's the most direct way for participants to experience audit-related scenarios.
