Adding/removing defaults is tricky, but it’s still backward.

Wait, is it really backward? I thought it was forward.

I vaguely recall that removing a field is usually breaking, but adding one with a default might not be. This is tricky!

I feel like this might be a forward evolution since defaults can help with new readers, but I could be mixing it up with another concept.

I remember practicing a question about schema evolution, and I think it was related to how defaults help maintain compatibility.

I think adding or removing a field with a default is considered backward compatibility, but I'm not entirely sure.

I'm a bit confused by this question. I know the CiscoCertUtil tool is used for certificate-related tasks, but I'm not sure of the specific functions. I'll have to guess and hope I get at least one right.

I went over a similar question in practice where the focus was on avoiding unnecessary transformations too, but I feel like there's more to consider with the service relationships in this case.

I'm a bit confused by this question. Is client access the same as user access or are they different? I'll need to review my notes to make sure I understand the concept properly.

Hmm, I'm a bit unsure about the difference between REST and Query requests. I'll need to think this through carefully.
