Wait, how is it 4? I thought it was 3.

Yep, 4 makes sense with 1 primary and 3 secondaries.

If I remember correctly, the replication factor should be the number of primaries plus secondaries, but I’m confused about the arbiter's role here.

I feel like the hidden secondary might not count towards the replication factor, but I can't recall exactly how that works.

I remember a practice question where we calculated the replication factor, and I think it was something like the total number of nodes minus the arbiter.

I think the replication factor is related to the number of nodes, but I'm not sure how the hidden secondary affects it.

Wait, I think the hidden secondary does count. So the total number of copies is 1 primary, 4 secondaries, and 1 arbiter, which makes the replication factor 6.

Okay, I got this. The replication factor is the total number of copies of the data, including the primary and all secondaries. So with 1 primary, 3 secondaries, and 1 arbiter, the replication factor is 5.

Hmm, I'm not sure about that. Doesn't the hidden secondary still count towards the replication factor? Let me think this through again.

I think the replication factor is 6, since there's 1 primary, 3 secondaries, and 1 arbiter. The hidden secondary doesn't count, right?

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.

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.
