Huawei Exam H13-623 Topic 4 Question 89 Discussion

Actual exam question for Huawei's H13-623 exam

Question #: 89
Topic #: 4

In the HyperMetro active-active data center solution, data centers A and B are deployed. If the storage array in data center A fails, which of the following statements are true? (Multiple Choice)

AUltraPath automatically disables all paths to data center A and forwards all I/Os to data center B.

BThe storage array in data center B uses a differential bitmap to record newly received I/Os.

CAfter the storage array in data center A is recovered, the active-active relationship is automatically restored. Based on the differential bitmap, incremental data is automatically synchronized without affecting upper-layer applications.

DIf the storage array in data center A takes the initiative to power off, a command is sent to the storage array in data center B, asking the storage array to take over services.

Option A sounds like it would leave us with a single point of failure, which kind of defeats the purpose of an active-active setup. I'm going to rule that one out.

Yeah, it seems risky to rely on just one data center in case of failure.

Wow, this exam question is really testing our knowledge of HyperMetro! I bet the engineers who designed this system had a lot of fun coming up with these crazy edge cases.

I'm going with B and C. The differential bitmap to record new I/Os and the automatic synchronization after recovery sounds like a solid disaster recovery solution.

Having automatic synchronization after recovery can save a lot of time and effort in restoring services.

I'm not sure about option C though. Can someone explain why incremental data is automatically synchronized?

D doesn't make much sense to me. Why would the storage array in data center A power off by itself, and how would that trigger a takeover in data center B? Seems like an odd scenario.

I agree with you, Emelda. Option A seems like the most logical choice in this scenario.

Option C seems like the right choice here. The active-active relationship should be automatically restored, and the data synchronization should happen without any disruption to the applications.

So, if the storage array in data center A fails, the data should still be synchronized without any disruption to services.

I think option A is correct because UltraPath should redirect I/Os to data center B.
