Definitely leaning towards B for the minimum test cases.

Wait, can you really cover all decisions with just two cases?

A is too simple, it won't cover all cases.

I think C is better for coverage.

Option B gives both true and false paths.

I thought option C looked good too, but I’m not confident if it covers the false condition properly. I guess I’ll have to double-check the logic.

I practiced a similar question where we had to cover all paths. I feel like we need to ensure that both conditions in the if statement are tested.

I’m not entirely sure, but I think option B might be right because it has two test cases that could cover both branches of the if statement.

I remember we talked about decision coverage and how we need to test both true and false conditions. I think we need at least two cases for this.

I'm a little confused by the different SQL injection types mentioned. I'll need to review my notes on SQL injection techniques to make sure I understand which ones would work best for this scenario.

I'm pretty confident that option C is the best answer here. The key point is that the invoice-related services are not using a centralized and standardized invoice service, which is a core principle of the Contract Centralization pattern. The other options don't seem to fully capture the issue.

This seems straightforward. I'll focus on the key details - the admin server has crashed and we need to start the managed servers in MSI mode. The question is asking which two files need to be copied from the admin server to the managed servers.
