Explanation

Huawei's HyperMetro NAS solution is a feature-rich active-active storage architecture, and all five options are genuine highlights. It operates without additional gateways (A), eliminating extra hardware complexity and cost. It provides a dual-arbitration mode (B) to reliably determine which site takes over during a network partition, preventing split-brain scenarios. Cross-site bad block repair (C) means a corrupted block on one site can be healed using the healthy copy from the peer site automatically. The solution is architected to support a smooth upgrade path to a three-data-center geo-redundant DR configuration (D), protecting your investment as requirements grow. Finally, FastWrite (E) is supported to accelerate write I/O by acknowledging writes to cache before they are committed to disk, improving performance in the active-active topology.

Since there are no wrong distractors here - this is an "all of the above" scenario - the exam is testing whether you know the full feature set without dismissing any option.

Memory tip: Use the acronym "NGCUF" - No gateway, Guardian (dual-arbitration), Cross-site repair, Upgrade path to 3DC, FastWrite - to recall all five highlights of HyperMetro NAS.
