E sounds right, synchronized instances are key for canary deployments.

I have a vague memory that the database isn't locked during the copy process, so I'm hesitant about option D being correct.

I practiced a question similar to this, and I think option B could be misleading; I don't recall traffic increasing significantly just because of a new instance.

I'm not entirely sure, but I feel like the database needs to support all versions of the service during a canary deployment, which makes me lean towards option C.

Oof, database questions are not my strong suit. I'm going to have to really focus on this one. Maybe I can eliminate a couple of the options and then make an educated guess.

Ah, this is a good one. I'm pretty confident that C is true - the database schema needs to be compatible across all service versions. But the other options have me a bit stumped.

Okay, let's see here. I think A and B are both true, but I'm not sure about the other options. Gotta be careful with database schema changes and increased traffic during a canary rollout.

This looks like a pretty straightforward IPSec VPN question. I think the key is remembering the two-stage process - the first stage is about establishing the identity of the peers, so the answer is probably IKE SA.

Hmm, I'm not entirely sure about this one. The options cover a few different responsibilities of the Service Desk. I'll need to think through each one to determine which is the primary responsibility.

E is a must, you need that second database instance to handle the traffic. Otherwise, your whole deployment could go up in flames!
