I thought BOOLEAN could only be TRUE or FALSE, but I guess not!

Wait, can you really use 't' and 'f'? That's surprising!

BOOLEAN is definitely not an alias for INTEGER.

I’m pretty confident that D is correct since TRUE and FALSE are standard keywords, but I’m unsure about E and how INTEGER values interact with BOOLEAN.

I remember practicing a question where BOOLEAN could only be TRUE or FALSE, so I think B might be correct.

I think option A is definitely incorrect because BOOLEAN is not an alias for INTEGER, but I'm not completely sure about the second one.

I feel like I've seen something about using 't' and 'f' for BOOLEAN values, so maybe C is wrong?

Hmm, I'm not too familiar with the Avaya Aura Media Server, so I'll need to think this through carefully. Let me re-read the question and options to make sure I understand what it's asking.

This looks like a straightforward NPSP configuration question. I'll review the options carefully and think through the memberships feature.
