HCIP-Storage V5.5 Questions and Answers

Question 9

Cache policies and configurations are involved in storage-layer performance optimization of Huawei flash storage. Which of the following statements is false about the high and low watermarks of a cache?

Options:

A.

Generally, the low watermark for storing dirty data in the cache should not be too low. The recommended value is 20%.

B.

Generally, the high watermark of the cache should not be too high, and the difference between the high and low watermarks should not be too small.

C.

If the high watermark of the cache is too high, I/O fluctuation and latency increase will occur usually when the current I/O traffic bursts.

D.

If the high watermark of the cache is too high, the write performance will be affected. If the low watermark of the cache is too low, the read performance will be affected.

Question 10

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?

Options:

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).

Question 11

Before configuring services for Huawei flash storage, you need to Initialize the system. Which statement about the initialization is false?

Options:

A.

You must change the IP addresses of the management network port and maintenance network port using the command-line interface (CLt) before applying for and activating a license.

B.

During security configuration management, read-only users have only the access permission to the storage device, that is, they can only perform query operations.

C.

When the TCP+SSl/TLS protocols are used for Syslog alarm notification, you need to set the certificate verification mode to improve the security of storage system logs.

D.

During the wizard-based initialization, you need to configure basic information, such as device information, device time, and licenses.

Question 12

An industry customer purchases several Huawei flash storage devices for service deployment. During routine management, an engineer finds that a controller of one device is faulty, but the fault is common, so the engineer does not need to perform emergency handling.

Options:

A.

TRUE

B.

FALSE
