I agree with B, node failures can spike IOPs.

Wait, isn't D a bit of a stretch?

I think A could also be a factor, but not sure.

C seems unlikely, resync throttling usually helps, right?

Definitely B and E, those make sense.

Changing the FTT value seems relevant too, but I’m not clear on how that directly relates to backend IOPs.

I practiced a question about resync throttling before, and I feel like that could also impact IOPs, but I can't recall the details.

I think a node failure could definitely lead to high backend IOPs, especially if it's trying to rebuild data.

I remember something about DRS settings affecting performance, but I'm not sure if "Aggressive" is the right choice here.

Hmm, the DRS threshold and node failure seem like the most straightforward answers here. I'll start by evaluating those and see if I can rule out the other options.

I feel pretty confident about this one. The vSAN policy protection level change from FTT=0 to FTT=1 is definitely going to increase backend IOPS as the system works to maintain the new protection level.

I'm a bit confused by the vSAN Resync throttling and object repair timer value options. Not sure how those would directly impact backend IOPS. I'll have to think that through.

Okay, let's see. The cluster DRS threshold and vSAN node failure seem like the most likely culprits here. I'll focus on those two options.

Hmm, this seems like a tricky one. I'll need to carefully consider the different factors that could lead to high backend IOPS on a vSAN cluster.

I think it could be a combination of both the vSAN node failure and the Resync throttling.

That's a good point, Starr. It's important to consider all possible causes.

Haha, imagine if the correct answers were A and D. The cluster DRS threshold set to Aggressive and the object repair timer value increased? Sounds like a recipe for disaster!

I agree with B and E, but I also think C could be a factor. If vSAN Resync throttling is enabled, it can lead to increased IOPs during the resync process.

Yes, I agree. C could also be a factor if vSAN Resync throttling is enabled.

I think the correct answers are B and E. A node failure can definitely cause high backend IOPs, and changing the protection level from FTT=0 to FTT=1 would also increase the load on the backend.
