Question 1

The scale-out storage system supports cabinet-level security. That is, N data blocks and M parity blocks are stored in different cabinets. If M nodes or M disks are faulty, the system can still read and write data without service interruption or data loss. If M cabinets are faulty, services may be interrupted.

A : TRUE

B : FALSE

Answer: A

Question 2

When demarcating a performance issue of Huawei flash storage, engineer A finds that the latency observed on the compute side is much longer than that on the storage side. This indicates that the issue most possibly occurred on the storage, for example, the disk performance upper limit has been reached.

A : TRUE

B : FALSE

Answer: B

Question 3

When demarcating a performance issue of Huawei flash storage, engineer A finds that the latency observed on the compute side is much longer than that on the storage side. This indicates that the issue most possibly occurred on the storage, for example, the disk performance upper limit has been reached.

A : TRUE

B : FALSE

Answer: B

Question 4

A government customer has purchased two Huawei flash storage devices and deployed them in different data centers for running remote replication services. When a primary/secondary switchover is performed for the remote replication pair, the primary and secondary sites record the data changes. When the secondary site becomes the primary site following the primary/secondary switchover, all data will be synchronized between the primary and secondary sites.

A : TRUE

B : FALSE

Answer: B

Question 5

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?

A : When 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.

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

C : The file service client can write plaintext data through the NFS/CIFS/DPC protocol.

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

Answer: C
