QUESTION NO: 1
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?

A. 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. B. Generally, the low watermark for storing dirty data in the cache should not be too low. The recommended value is 20%. C. 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, read performance will be affected. D. 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.

QUESTION NO: 5
An engineer needs to install the hardware of a Huawei flash storage device. Which of the following statements is true about hardware installation?

A. When connecting cables of the flash device, the engineer needs to connect AC power cables to the same independent power supply to ensure cable redundancy. B. When removing filler panels from a cabinet, the engineer needs to use flat-head screwdrivers and floating nut hooks to remove M6 screws from filler panels. C. If the flash storage device is a mid-range or entry-level flash storage device, the engineer needs the installation template to determine the device installation positions after removing filler panels from the cabinet. D. If the flash storage device is high-end flash storage device, the engineer needs to connect the ground cable of the cabinet before the external power cable, and install the cabinet after the connection is complete.

QUESTION NO: 6
FILL BLANK
In RAID 2.0+, the storage system divides each disk in a storage pool into 4 MB ____ for logical space management.

Correct Answer:

CKs
Explanation:
In Huawei RAID 2.0+, each disk in a storage pool is divided into fixed-size 4 MB chunks (CKs) for logical space management.

QUESTION NO: 7
Assume a financial customer purchased several Huawei flash storage devices for service deployment. During the use of the storage devices, an engineer found that the overall latency is high and the system response is slow. Which of the following measures can the engineer take to troubleshoot this issue? (Choose all that apply.)

A. Replace the memory and CPUs. B. Check whether the hit ratio changes abruptly on the storage side. C. Use FTDS, the latency locating tool on the storage side, to analyze the modules with abnormal latency. D. Check whether special operations are performed or unexpected services are triggered on the host when the issue occurs.

A. When creating a user or user group quota for a namespace (i.e. Dtree is left empty), the namespace for which the quota needs to be created is empty B. When creating a quota for a specified user or user group, you need to create the user or user group first. C. When creating a quota for a specified Dtree, the selected Dtree must be empty. D. Before creating a quota, you need to complete the creation of a namespace or Dtree.

Correct Answer: B,D

QUESTION NO: 10
An enterprise has purchased several Huawei OceanStor Pacific series storage devices. An engineer wants to configure the CIFs share service on them. Which of the following statements are true about the service configurations?

A. After CIFs shares are allocated to domain users, the engineer cannot modify the domain user information. Otherwise, the CIFS shares cannot be accessed. B. In a domain environment, the engineer needs to create a local authentication user, add the local user to a user group, and use the group for authentication to access a share. C. If a user's service network has multiple network segments, the engineer can configure multiple subnets to enable clients in different service network segments to access the storage network. D. Before creating a converged resource pool, the engineer must enable the file service for nodes.
Otherwise, subsequent operations cannot be performed.

QUESTION NO: 11
Redundancy policies are involved in the planning of storage pools on Huawei OceanStor Dorado series storage devices. Which of the following statements are true about redundancy policies?
(Choose all that apply.)

A. At the same RAID level, the RAID usage of the disk redundancy policy is smaller than that of the enclosure redundancy policy. B. An enclosure redundancy policy can be set only when a storage pool is being created. After the storage pool is created, the redundancy policy cannot be modified. C. An enclosure redundancy policy does not tolerate enclosure power outage, whereas a disk redundancy policy does. D.
