QuestionQ22
Overview of Huawei's AI Development Strategy and Full-Stack, All-Scenario AI PortfolioIn real production environments, Huawei converged storage’s HyperMetro feature ensures that customers’ services run without interruption. Which statement about HyperMetro is false?
- A In cross DC HyperMetro deployments involving long-distance transmission (a minimum of 25 km for IP networking and 80 km for Fibre Channel networking), dense wavelength division multiplexing devices must be used to ensure a low transmission latency.
- B By default, when creating a HyperMetro pair, the local storage system is set as the preferred site and the remote storage system as the non-preferred site.
- C If the quorum server is inaccessible, HyperMetro works in static priority mode. When an arbitration occurs, the preferred site wins the arbitration and provides services.
- D The data, logs, and change information of a medium- or large-sized database are stored on different LUNs of a storage system. Placing these LUNs in a protection group (PG) and then creating a HyperMetro consistency group for that PG can ensure data consistency in replication.
