Huawei Exam H13-623 Topic 1 Question 84 Discussion

Actual exam question for Huawei's H13-623 exam

Question #: 84
Topic #: 1

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.

I think both options B and C could be correct. The use of a differential bitmap seems crucial in this scenario.

I'm not sure about that. I think option C makes more sense, with incremental data synchronization.

I disagree, I believe option D is the correct answer. The storage array in data center B should take over services.

I think option A is correct, UltraPath should disable all paths to data center A.

I still think option D is more practical, it ensures quick service takeover in case of failure.

That's a good point, Maybe option A is the right choice after all.

But what if the storage array in data center A fails? Wouldn't it make sense for all I/Os to be redirected to data center B automatically?

I'm leaning towards option D, it makes more sense to me.

Good question. I'm not entirely sure about option D either. Perhaps it's a trick question, or there's some nuance we're missing. We should discuss this as a group.

I believe option D is also valid. It makes sense for the secondary storage array to take over if the primary fails.

I'm not so sure about option C. Will the synchronization process really be seamless?

I agree with you, Dacia. UltraPath should handle the path switch to data center B.

I think option A is correct. UltraPath would manage the failover automatically.

What about option D? I'm not sure about that one. Does the storage array really send a command to the other data center to take over services?

Yeah, that makes sense. And option A seems correct too, as UltraPath should automatically redirect I/Os to the healthy data center.

Hmm, let me think about this. I believe options B and C are correct, as the HyperMetro solution uses a differential bitmap to track changes and can automatically synchronize data after recovery.

I agree. The question is asking about what happens when the storage array in data center A fails, which is a critical situation that we need to be prepared for.

This question seems to be testing our understanding of the HyperMetro active-active data center solution. It's important to know how the system behaves in different failure scenarios.
