Question #1
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 storage devices. Which of the following statements is false about the engineer’s configuration?
- AWhen creating a namespace, the engineer needs to select a security style and application type.
- BBefore creating a converged storage pool, the engineer must enable the file service for nodes on DeviceManager.
- CIf 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.
- DWhen 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.

Question #2
In Huawei container storage solution, CSI is short for Container Storage Interface. Which of the following statements is false about Huawei CSI?
- ACSI Node runs on each worker node of Kubernetes on the Pod in DaemonSet mode and can be used to mount and unmount related storage resources.
- BCSI Controller runs independently on a worker node on the Pod in StatefulSet mode and is used to interact with the storage and create and delete resources on the storage side.
- CHuawei storage and Huawei CSI driver need to communicate with each other through RESTful to provide NAS/SAN storage resources.
- DCSI Driver developed by Huawei is mainly used to implement to call initiated by sidecar on Huawei storage.

Question #3
A government customer purchases multiple Huawei flash storage systems to deploy remote replication services. During asynchronous remote replication of LUNs, engineers need to replicate data at time point X from the primary LUN to the secondary LUN based on data change logs (DCLs). After data synchronization is complete, snapshots of the primary and secondary LUNs are automatically deleted, in this way, storage space occupation is reduced.

Question #5
A financial customer has purchased two OceanStor Dorado 18000 series storage devices for service deployment. To ensure service data reliability, an engineer configures the HyperSnap feature on the storage devices. Which of the following commands can the engineer use to change the snapshot rollback rate on the command line interface (CLI)?
- Achange snapshot speed
- Bchange snapshot flowctrl
- Cshow qos snapshot_flowctrl_lun
- Dchange snapshot deactivate

Question #6
DME IQ focuses on service processes and overall implementation solutions, which can ensure high security. Which of the following are security capabilities in the collection phase? (Choose all that apply.)
- AAll operations on the Secure Cloud Gateway are recorded, the uploading records can be traced, and integrity check is performed to prevent tampering.
- BThe purpose of the data collection is clear, the data set is minimized, and deployment occurs only with the customer’s permission. This complies with local laws and regulations, and only related to O&M information but not device service data is obtained.
- CFor one-way requests, only the outbound policy on the customer side needs to be enabled. The DME IQ cloud system will never proactively initiate requests to the customer side.
- DBefore being stored, data is encrypted using AES256 to prevent information leakage.

Question #7
A financial customer purchases several Huawei flash storage devices for service deployment. During routine storage management, if an engineer logs in to a storage device as a data protection administrator, which of the following operations can the engineer perform?
- AManaging the antivirus function
- BManaging clone consistency groups and LUN consistency groups
- CManaging security policies and security rules
- DManaging HyperCDP objects and snapshot consistency groups

Question #8
A financial customer has purchased several Huawei flash storage devices for service deployment. To ensure service continuity, an engineer configures the HyperMetro feature on the storage devices. Which of the following commands can the engineer use to remove a LUN on the command line interface (CLI)?
- Aremove hyper_metro_consistency_group pair
- Bremove lun_group lun
- Cremove protect_group lun
- Dshow protect_group general

Question #9
When delivering a flash storage project, Huawei engineers introduced the arbitration mechanism of HyperMetro to the customer. Which of the following statements is false about the arbitration modes?
- AIf no quorum server is configured, HyperMetro works in static priority mode. When an arbitration occurs, the preferred site wins the arbitration and provides services.
- BIn quorum server mode, of the link between storage systems is down, each storage system sends an arbitration request to the quorum server.
- CIn quorum server mode, the quorum server can be deployed only on physical machines and not on virtual machines.
- DIn static priority mode, if the preferred site of a HyperMetro pair breaks down, the non-preferred site does not automatically take over HyperMetro services. As a result, the services stop, and the customer must forcibly start the services at the non-preferred site.
