Huawei H13-624_V5.5 Exam - Topic 4 Question 18 Discussion

When delivering a flash storage project, Huawei engineers introduced the arbitration mechanism of HyperMetro to the customer. Which of the following statements is false about the arbitration modes?
C) In quorum server mode, the quorum server can be deployed only on physical machines and not on virtual machines.
A) If no quorum server is configured, HyperMetro works in static priority mode. When an arbitration occurs, the preferred site wins the arbitration and provides services.
B) In static priority mode, if the preferred site of a HyperMetro pair breaks down, the non-preferred site does not automatically take over HyperMetro services. As a result, the services stop, and the customer must forcibly start the services at the non-preferred site.
D) In quorum server mode, if the link between storage systems is down, each storage system sends an arbitration request to the quorum server.

When delivering a flash storage project, Huawei engineers introduced the arbitration mechanism of HyperMetro to the customer. Which of the following statements is false about the arbitration modes?

Show Suggested Answer Hide Answer
Suggested Answer: C

The HyperMetro feature in Huawei storage systems, such as OceanStor Dorado, provides active-active data access with arbitration mechanisms to handle site failures. The *HCIP-Storage V5.5 Training Material (Module 4: Storage Design and Implementation)* details HyperMetro arbitration modes:

- Option A: True. The material states: ''In the absence of a quorum server, HyperMetro operates in static priority mode, where the preferred site is designated to win arbitration and continue services during a failure.''

- Option B: True. The material explains: ''In static priority mode, if the preferred site fails, the non-preferred site does not automatically take over to avoid split-brain scenarios. Services stop, and manual intervention is required to forcibly start services on the non-preferred site.''

- Option C: False. The material clarifies: ''In quorum server mode, the quorum server can be deployed on physical machines or virtual machines, provided it meets the performance and network requirements.'' This makes the statement that it can only be deployed on physical machines incorrect.

- Option D: True. The material confirms: ''In quorum server mode, if the link between storage systems fails, both systems send arbitration requests to the quorum server to determine which site continues providing services.''

Thus, option C is false.

No, B is correct. Manual intervention is needed if preferred site fails.

I feel B is misleading. Services should auto-switch, right?

I think option C is false. Quorum servers can be virtual too.

C is definitely the false one. Virtual deployment is common.

I’m leaning towards A being false. Static priority should allow auto-switch.

I feel like option C is the false statement, but I can't quite recall why. Maybe we discussed virtual machines being used for quorum servers in class?

I vaguely recall something about static priority mode, but I can't remember if it really stops services completely if the preferred site fails.

I think option B sounds familiar from practice questions, where the non-preferred site doesn't take over automatically. That one seems true to me.

I remember studying the arbitration modes, but I'm not entirely sure if the quorum server can only be on physical machines. That seems a bit strict.
