Hydrogen embrittlement could be a factor too, right?

Wait, 740 F? Isn't that too low for 885 F embrittlement?

I think it's more likely sulfide stress corrosion cracking.

Wait, I'm confused. Isn't a SYN/ACK segment part of the three-way handshake to initiate a connection? I think the answer is A, but I'm not 100% sure.

Querying the AsyncApexJob object sounds like a good approach, but I want to make sure that's actually one of the correct answers. I'll need to review the documentation to be sure.
