C is interesting, but not sure if everyone knows how to use internal DNS.

Wait, can clients really use internal DNS like that? Seems risky.

I think A is better for direct access, less complexity.

Option B sounds solid, using Cloud DNS is a good move.

I feel like option D is a bit off. We discussed API versioning, but I don't recall using the instance name directly for external access. It seems like it wouldn't work for multiple clients outside the VPC.

I’m a bit confused about the internal DNS options. Option C mentions using the instance name, but I thought that was only for internal communication. Would clients really be able to connect that way?

I remember practicing a similar question where we had to set up DNS records. Option B sounds familiar because it involves using Cloud DNS, which could be useful for clients to connect by name instead of IP.

I think option A makes sense since it mentions using a static external IP, which is something we covered in class. But I'm not entirely sure if that's the best approach for multiple clients.

I'm pretty confident that the correct answer is to create a user-assigned managed identity. That's going to be the key to authenticating and authorizing the SBD.

I'm a bit confused by this question. I'm not entirely sure what process exceptions are used for. I'll have to guess and hope I can eliminate some of the options.
