Which arbitration mode does Huawei's active-active (HyperMetro) solution support? (Multiple choice)

Question

Options

• AQuorum disk
• BQuorum server
• CHeartbeat
• DStatic priority

Explanation

Huawei HyperMetro supports two arbitration modes for resolving split-brain scenarios - Quorum Server (B) and Static Priority (D). Quorum Server uses a third-party server as a tiebreaker: when the two sites lose replication communication, each site races to register with the quorum server, and the one that succeeds continues serving I/O. Static Priority assigns a pre-configured preference to one site, so in a split-brain event, the higher-priority site automatically stays active while the other pauses I/O.

Option A (Quorum Disk) is incorrect because HyperMetro does not use a shared disk/LUN as a tiebreaker - that pattern belongs to cluster solutions like WSFC or vSAN, not HyperMetro. Option C (Heartbeat) is the detection mechanism (how sites monitor each other's replication link health), not an arbitration mode - it tells the system a problem exists but doesn't decide which site wins.

Memory tip: Think "QS·SP - Quorum Server and Static Priority." Heartbeat is the sensor, not the judge; Quorum Disk is someone else's technology, not Huawei's.
