I’m a bit confused about the NAT gateway; I thought it was mainly for outbound internet access, not for connecting to RDS, so I’m not sure about option D.

I practiced a question similar to this, and I think whitelisting IPs is usually necessary, so option B might be correct too.

I'm not entirely sure, but I feel like connecting the VPCs through CEN could be important for private communication, so maybe option C?

I remember something about security groups being crucial for allowing outbound access, so I think option A makes sense.

This seems like a straightforward question about email security policies. I'll carefully read through the options and think about the most likely reason the email was filtered.

Ah, I see now. Save, compile, and then freeze the definition. Got it. This exam question is straightforward if you know the process.

Okay, I've got this. The question is asking what needs to be decided before considering the treatment of risks. That means we need to establish the criteria for determining risk acceptance first, which is option A.
