I’m surprised there’s no option for just warning instead of auto-deleting!

A makes the most sense, but C sounds interesting too.

Wait, isn't it B? I thought parent keys can't be deleted if children exist.

Definitely A! That's how cascade works.

Hmm, I'm a bit unsure about this one. Creating a separate CloudWatch Logs stream for each microservice might get unwieldy as the number of services increases. Maybe option C, configuring VPC Flow Logs, could be a better solution to track the communication between the services.

I remember calculating total receipts from previous exams, but I'm not sure if the January figure is $245,000 or $320,000.

I feel pretty confident that B is the right answer here. The Analytics Builder is designed for reporting and analysis, so that's where I'd expect to find the comprehensive data I need to answer this question.

I feel like we practiced a question similar to this, and it mentioned that immunizations are covered, so that's probably not the right choice.
