Refer to the exhibit.

After an abrupt power outage, an administrator receives a number of alerts indicating disks are failed. Prism Element shows a large number of disks offline as seen in the diagram. This single block, four node cluster is configured FT1 with an RF2 container holding all user data.

What number of drive failures on different domains (node, block, or rack) could this configuration have tolerated prior to seeing data unavailability?

Nope, it’s actually 4 failures, check your facts!

Definitely 2, RF2 means redundancy across nodes.

Surprised it can only handle 2! Seems low for a 4 node cluster.

I thought it was 3 failures, but I guess not!

I’m leaning towards 1 failure being the max, but I need to double-check how that relates to the nodes in this setup.

I feel like RF2 means it can handle a certain number of failures, but I can't recall if it's 3 or 4.

I think we practiced a similar question where we had to calculate tolerances based on node configurations. Could it be 2?

I remember something about fault tolerance, but I'm not sure how many failures RF2 can handle.

Based on the information provided, I believe the answer is C. The configuration can tolerate 3 drive failures across different domains before seeing data unavailability.

I'm a bit confused by the terminology here. What exactly is "FT1" and "RF2"? I'll need to make sure I understand those concepts before I can answer this.

Okay, the question is asking about the number of drive failures this configuration could tolerate. I think I need to consider the replication factor and the cluster setup.

Hmm, this looks tricky. I'll need to carefully read through the details and think about the redundancy and fault tolerance of the configuration.
