A school has purchased two Huawei OceanStor Pacific series storage devices for service deployment. An engineer wants to configure the distributed parallel client (DPC) on the storage devices.
Which of the following statements is false about the engineer’s configuration?
- A . If upper-layer services require high data security, the engineer needs to set the storage pool type to "Self-encrypting" when creating a converged storage pool.
- B . Before creating a converged storage pool, the engineer must enable the file service for nodes on DeviceManager.
- C . When creating a namespace, the engineer needs to select a security style and application type.
- D . When the storage network is a Remote Direct Memory Access over Converged Ethernet (RoCE) network, the engineer can run the "systemctl stop lldpad.service" command to disable the lldpad
service.
A financial customer wants to configure the DME IQ service to perform daily management of flash storage. Before setting up DME IQ, it is necessary to open the server port of the DME IQ cloud to ensure that the storage device can send HTTP requests to the DME IQ cloud normally.

- A . 8448/TCP
- B . 8900/TCP
- C . 7448/TCP

Distributed storage uses a globally unified namespace. Its big data service can provide location services and load balancing for resources in different regions, allowing clients to access space and resources in ().
An Internet customer has deployed a remote replication environment based on multiple flash storage devices. During actual service running, the customer discovers that there are multiple running statuses for a remote replication pair.
Which of the following statements is true about the running status of a pair?
- A . After a pair is disconnected, if the pair is deleted from the primary or secondary site, which causes configuration inconsistency between the primary and secondary sites, the pair running status changes to "To be recovered."
- B . When the pair running status is "Split", the pair relationship between the primary and secondary LUNs is interrupted (not manually).
- C . When the pair running status is "Normal", data synchronization between the primary and secondary LUNs is complete.
- D . When the pair running status is "To be synchronized", the pair relationship between the primary and secondary LUNs must be manually disconnected to meet the service requirements of a single LUN.
