Nah, I think it’s 4 because of the hidden secondary.

I’m confused about the hidden secondary. Does it count or not? I thought it was 5, but now I’m second-guessing myself.

I'm not entirely sure, but I remember something about hidden secondaries not counting towards the replication factor. Could it be 3 then?

I think the replication factor is the total number of nodes that hold a copy of the data, so maybe it's 4 since we have 1 primary and 3 secondaries?

I practiced a similar question where the arbiter didn't count towards the replication factor. I feel like the answer might be 4 in this case.

The log file seems to have a lot of information, but I'm not sure what the logging level is. I'll need to read through it carefully.

Definitely go with B. Traceability is the way to track how changes in one requirement affect the others.

I'm a little confused by the wording of some of these options. Do I need to enable Data-In-Transit encryption first, or is that a separate step? I'll need to double-check the documentation to make sure I fully understand the requirements.
