Wait, why is there an arbiter if there are only 3 secondaries? Must be a trick question. I'll go with D just to be safe.

D definitely seems right. The hidden secondary doesn't count towards the replication factor, so it's 6 nodes in total.

So, the replication factor for this cluster is indeed 6. The hidden secondary doesn't contribute to the replication factor count.

Yes, that's correct. The replication factor is calculated based on the number of visible nodes in the cluster.

I agree with Solange, the hidden secondary and arbiter are not part of the replication factor, so it should be 4.

I think the answer is D. The replication factor is 6 since there's 1 primary, 3 secondary, and 1 arbiter.

No, the correct answer is B. The replication factor is 3 because only the secondaries count towards replication factor.

The replication factor is 4, because we count the primary and the visible secondaries.
