An industry customer purchases a Huawei flash storage device for service deployment. During an inspection, an engineer finds that the alarm indicator on a controller enclosure of the device is steady yellow, which means that a major of higher-severity alarm has been generated on the storage device.

• A. TRUE
• B. FALSE

Engineers can configure multiple alarm and event handling policies on Huawei flash storage.
Which of the following alarm and notification modes are supported by flash storage? (Choose all that apply.)

• A. SMS notification
• B. WeChat notification
• C. Alarm dump
• D. Syslog notification

NVMe over Fabrics can map NVMe commands and data to multiple fabric links, including Fibre Channel, InfiniBand, RoCE v2, iWARP, and TCP.

• A. TRUE
• B. FALSE

An industry customer has purchased two Huawei OceanStor Pacific scale-out storage devices and deployed them in different equipment rooms. Now an engineer wants to configure the HyperMetro feature on the two devices in static priority mode. Equipment room A is the preferred site. After the link between the two storage devices is down, what is the running status of the HyperMetro pair and what is the arbitration result?

• A. The running status of the HyperMetro pair is "Normal". The arbitration result is that the volume in equipment room A is inaccessible and that in equipment room B continues providing services.
• B. The running status of the HyperMetro pair is "Normal". The arbitration result is that the volumes in equipment rooms A and B continue providing services.
• C. The running status of the HyperMetro pair is "To be synchronized". The arbitration result is that the volume in equipment room A is inaccessible and that in equipment room B stops providing services.
• D. The running status of the HyperMetro pair is "To be synchronized". The arbitration result is that the volume in equipment room A continues providing services and that in equipment room B stops providing services.

Huawei OceanStor Pacific series is an intelligent scale-out storage product that supports large- scale scale-out and delivers high reliability. Which of the following statements are false about the product's reliability? (Choose all that apply.)

• A. The product leverages link aggregation to ensure transmission link redundancy and performs link switchover or isolation to ensure service continuity if a link becomes faulty or subhealthy.
• B. In terms of data reliability, multiple RAID policies are supported based on the traditional disk-level RAID mode.
• C. The product uses the multi-copy technology to implement the intra-node RAID function. If a node is faulty, the system reliability is not degraded and even remains higher than that of the EC mechanism.
• D. The product adopts Kunpeng processors to integrate functions of multiple chips and effectively improve hardware reliability.
