Wait, does SLB really eliminate all SPoFs? That seems too good to be true!

D sounds a bit sketchy, I don't think SLB does rsync.

C seems off, I don't remember needing an SLB agent on all instances.

I think B is true too, new IPs are assigned when recreating.
RE

A is definitely correct, health checks are crucial!

I don't recall anything about rsync in relation to SLB, so I'm leaning towards option D being incorrect. It seems like a different function altogether.

I practiced a question similar to this, and I think option C is definitely correct. The SLB agent needs to be configured on the ECS instances for it to work properly.

I remember that Health Check feature being really important for SLB, so I think option A is correct. It helps keep the service running even if some instances fail.

I'm not entirely sure about option B. I think when you recreate an SLB instance, it might keep the same IP, but I could be mixing that up with another service.

Okay, I remember learning about this in class. Let me see if I can recall the key elements that go into determining the Maximum Tolerable Downtime.

Ah, I see what they're getting at now. The remaining technological life is actually an important factor to consider, so that can't be the one we exclude. I'll go with option A, remaining legal (or legal protection) life.

This seems pretty straightforward. I just need to figure out the total rent received in advance and the portion that relates to the period after 30 September. I'm confident I can get the right answer here.

I'm a bit confused about the difference between HDT and HDP pools. The third option mentions enabling Active Flash on HDP pools, but the second option was specific to HDT. I'll need to double-check the details on those pool types.

Okay, I've got this. The rules of evidence are all about ensuring the reliability and admissibility of evidence in legal proceedings. "Non-admissible" is the only option here that doesn't directly relate to that.
