One peer failing sounds too risky for me.

No way, zero peers can fail!

Wait, can four really fail? That seems off.
JO

Yeah, I agree with that!

I think three peers can fail before data is unsearchable.

I’m confused about the relationship between RF and SF. If RF is 4, does that mean we can only afford to lose 3 peers? I’m leaning towards option C.

This question feels familiar. I practiced one where the RF was lower, and we could lose more peers. I think here, it might be just 1 peer that can fail safely.

I’m not entirely sure, but I feel like the search factor of 3 means we can lose some peers without losing access. Maybe 3 peers can fail?

I think I remember that with a replication factor of 4, we need at least 4 copies of the data to be available. So, if 4 peers fail, it might become unsearchable?

This question seems straightforward, I think I can identify the steps in Lewin's model of change pretty well.

I'm feeling pretty confident about this one. Based on my understanding, cloud-init provides its own startup mechanism that replaces the instance's original init system, so I'm going to go with option C.

This seems like a straightforward question about business continuity. I'll think through the options carefully and choose the one that best fits.

Wait, so if four peers fail, we can still search? That's like trying to find a needle in a haystack, but the haystack is on fire. Good luck with that!

This is a tricky one, but I think the answer is B) One peer can fail. The replication factor of 4 means we need at least 3 peers to search, so if one peer fails, we're still good.
BE

Yes, losing one peer out of 10 should still allow us to search the data without any issues.

Good to know, thanks for clarifying!
DA
Dana

That makes sense, with a replication factor of 4 and a search factor of 3, we can afford to lose one peer.
DE
Deonna

That's correct, as long as only one peer fails, we can still search the data.

I agree, the answer is B) One peer can fail.

I agree, the answer is B) One peer can fail.

I'm not sure about this one. The replication factor seems to be the key here, but I can't quite figure it out. I'll have to think about it some more.

A) Zero peers can fail.
AB

Well, if 4 peers fail, that means we'd still have 6 peers left, which is above the search factor of 3, so I think D) Four peers can fail is the right choice.
JO
Joana
1 year ago
Hmm, let me think about this. With 10 search peers, a replication factor of 4, and a search factor of 3, I'd say that C) Three peers can fail is the correct answer.
DE
Denise

That makes sense, one peer can fail without affecting the searchability of the data.
RA
Rachael
1 year ago
I agree, C) Three peers can fail is the correct answer.
ET
Ettie

I'm not sure, but it makes sense that if we have 10 search peers and a Replication Factor of 4, we can tolerate losing three of them before data becomes unsearchable. So, I'll go with C) Three peers can fail.

I agree with Paola, because with a Replication Factor of 4 and Search Factor of 3, we can afford to lose up to three search peers.
