Which of the following statements is false about the working principles of HyperReplication?

• A. In synchronous remote replication mode, a synchronous remote replication relationship is set up between a primary LUN at the production site and a secondary LUN at the DR site, and initial synchronization is started.
• B. In synchronous remote replication mode, after receiving a write I/O request from a host, the primary storage system sends the write I/O request to both the primary and secondary LUNs.
  After data is successfully written to both the primary and secondary LUNs, the write I/O is returned to the host.
• C. Asynchronous remote replication relies on the snapshot technology. When a host initiates a write request, the storage system returns a write success message to the host only after data is successfully written to the secondary LUN.
• D. Remote replication can be implemented in synchronous or asynchronous mode. The principle of writing data to the secondary LUN varies according to the mode.

When the OceanStor Pacific series system is overloaded, inline deduplication automatically stops and switches to post-process deduplication. At this moment, data is flushed to disks for persistent storage. When sufficient system resources are available, the system starts post-process deduplication.

• A. TRUE
• B. FALSE

An industry customer has purchased a Huawei OceanStor Pacific scale-out storage system for service deployment. An engineer configures NFS file sharing on the storage system through NFSv4.0. Which of the following commands can the engineer use to switch the user view to the developer view on the command line interface (CLI)?

• A. change domain ad_manager operation=develop
• B. change nas_ldap advanced_config
• C. change user_mode current_mode user_mode=developer
• D. change dns general address=develop

Redundancy policies are involved in the planning of storage pools on Huawei OceanStor Dorado series storage devices. Which of the following statements are true about redundancy policies?
(Choose all that apply.)

• A. An enclosure redundancy policy does not tolerate enclosure power outage, whereas a disk redundancy policy does.
• B. At the same RAID level, the RAID usage of the disk redundancy policy is smaller than that of the enclosure redundancy policy.
• C. An enclosure redundancy policy can be set only when a storage pool is being created. After the storage pool is created, the redundancy policy cannot be modified.
• D. The enclosure redundancy policy enables the system to tolerate failure of a single disk enclosure without service interruption or data loss.

When deploying a Huawei converged storage system, engineer A uses the UltraPath software.
Which of the following statements are false about the load balancing algorithms of UltraPath?
(Choose all that apply.)

• A. The min-queue-depth algorithm refers to the minimum queue depth algorithm. UltraPath is configured with this algorithm by default.
• B. The min-task algorithm is a round robin algorithm and can be used in scenarios where the service I/O models delivered by the host have little difference.
• C. The algorithms fall into three types: min-queue-depth, round-robin, and min-task.
• D. Round-robin is a min-task algorithm and can be used in scenarios where service I/O model data blocks delivered by the host are large.
