Question 1

When delivering a Huawei OceanStor Pacific storage project, a Huawei engineer vigorously promoted the SmartEncryption feature of scale-out storage to customers. Which of the following statements is false about this feature?

AWhen the data is read using the DPC or NFS protocol, the SED obtains the identity authentication key from the key management server, reads and decrypts the ciphertext data, and then returns the plaintext data to the protocol layer. The protocol layer returns the plaintext data to client applications.

BThis feature supports encrypted data write using NFS, CIFS, HDFS, or S3. Data is decrypted and read using NFS, CIFS, HDFS, or S3.

CThe file service client can write plaintext data through the NFS/CIFS/DPC protocol.

DHuawei OceanStor Pacific series scale-out storage supports disk encryption. All data delivered by services is stored on self-encrypting disks (SEDs).

Answer : C

Question 2

An engineer wants to configure the iSCSI block service on a Huawei scale-out storage device. Which of the following operations must be performed by the engineer?

ACreate a block storage pool.

BConfigure the iSCSI service.

CConfigure DPC share access on a client.

DInstall DPC.

Answer : A, B

Question 3

An engineer can use multiple common management software to configure, manage, and maintain Huawei converged storage. Which of the following statements is false about the software and corresponding functions?

ASmartKit provides capabilities such as alarm reporting, file upload, and remote access.

BDeviceManager allows the engineer to allocate storage resources, manage users, manage data protection features, monitor device performance, and manage alarms.

CDME IQ enables cloud-based management, remote maintenance, automatic service request creation, and prediction and prevention, comprehensively improving customers' O&M capabilities.

DThe command-line interface (CLI) allows the engineer to allocate storage resources, manage users, manage data protection features, monitor device performance, and manage alarms.

Answer : A

Question 4

In Huawei container storage solution, CSI is short for Container Storage Interface. Which of the following statements is false about Huawei CSI?

ACSI Driver developed by Huawei is mainly used to implement the call initiated by sidecar on Huawei storage.

BHuawei storage and Huawei CSI driver need to communicate with each other through RESTful to provide NAS/SAN storage resources.

CCSI 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.

DCSI 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.

Answer : B

Question 5

Assume a financial customer purchases a Huawei OceanStor Pacific scale-out storage system for future service deployment. Which statement is false about software installation of the storage system?

ADuring block service installation, if management nodes are deployed where compute and storage nodes are converged, the number of vCPUs on each converged compute and storage node must be greater than or equal to 20.

BDuring block service installation, if converged deployment of storage and compute nodes is required, the difference between the disk quantities on any two nodes in the same storage pool cannot be greater than 2 or 30% of the disk quantity on the node having most disks.

CIf wizard-based software installation is used, an engineer must manually add nodes, configure networks, and create a control cluster on DeviceManager, and then install the OceanStor Pacific series software.

DTo install the Distributed Parallel Client (DPC), the memory required for running the DPC software on a compute node must be greater than or equal to 20 GB.
