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.

User 2: 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.
