• Question 92:

  As the new storage administrator, you are tasked with the procurement of a new batch of SSD drives to replace the older drives that has reached the end of life. You have the option of SLC, MLC and TLC SSD. Which of the following will be your choice with a limited budget and medium level of reliability concerns? (Select All that Apply)

  A. Purchasing all SLC SSD drives for maximum savings on cost regardless of reliability.
  B. Purchasing all TLC SSD drives for the storage system for the best reliability and performance.
  C. Purchasing the MLC SSD if within budget range for core applications and services for better performance and reliability.
  D. Purchasing SLC SSD drives that has lowest cost and reliability for storage purposes of non critical applications
  C. Purchasing the MLC SSD if within budget range for core applications and services for better performance and reliability.
  D. Purchasing SLC SSD drives that has lowest cost and reliability for storage purposes of non critical applications

  Explanation

  When choosing between different types of SSDs, the main factor to consider is the trade-off between cost and reliability. SLC (Single-Level Cell) SSDs are the most reliable and have the longest lifespan, but they are also the most expensive. TLC (Triple- Level Cell) SSDs are less reliable than SLC SSDs, but they are also less expensive. MLC (Multi-Level Cell) SSDs are a good balance between cost and reliability, they are more affordable than SLC SSDs and more reliable than TLC SSDs.

• Question 93:

  Regarding OceanStor V3 LUN deletion, what is wrong in the following description?

  A. The deduplication function is used together with SmartCache to accelerate performance
  B. The taken-over heterogeneous array LUN supports block-level deduplication
  C. Deduplication and remote replication cannot coexist on the same LUN
  D. When the LUN is created, the deduplicated LUN is selected and cannot be restored to the state without deduplication.
  B. The taken-over heterogeneous array LUN supports block-level deduplication

  ---

  Explanation

  Resolution: On the premise of enabling SmartCache in the file system, delete the SmartCache accelerated fingerprint using the file system To improve the system deduplication processing performance.

• Question 94:

  Description 1: A RAID consisting of several hard disks is called a physical volume.

  Description 2: RAID 5 can improve the read and write rate and provide a certain degree of data security, but when there is a single hard disk failure

  At this time, read and write performance will be greatly reduced.

  A. Description 1 is correct, description 2 is correct
  B. Description 1 is correct, description 2 is incorrect
  C. Description 1 is wrong, description 2 is correct
  D. Description 1 error, description 2 error
  C. Description 1 is wrong, description 2 is correct

  ---

  Explanation

  Analysis: RAID consists of several hard disks (physical volumes); RAID can create one or more logics according to the specified capacity Volume, a logical volume is a hard disk (physical volume) for the host.

• Question 95:

  The only cable type that can be used to connect disk enclosures is the mini SAS cable.

  A. FALSE
  B. TRUE
  A. FALSE

  ---

  Explanation

  While the mini SAS cable is a common type of cable used to connect disk enclosures, there are other types of cables that can also be used, such as the SAS cable and Fibre Channel cable.

• Question 96:

  Which of the following operations is a daily maintenance item in data center storage?

  A. View and handle alarms
  B. Inspection storage equipment
  C. Check the computer room environment
  D. Check the internal environment of the rack
  A. View and handle alarms

  Explanation

• Question 97:

  In HUAWEI OceanStor,HyperSnap of a LUN uses the Copy On Write method to keep track of changes blocks

  A. TRUE
  B. FALSE
  A. TRUE

  ---

  Explanation

• Question 98:

  Deduplication is a data reduction technology that compresses large-size data blocks to reduce the physical storage capacity for storing data, thereby meeting increasing storage capacity requirements.

  A. False
  B. True
  B. True

  ---

  Explanation

  Deduplication is a data reduction technology that compresses large-size data blocks to reduce the physical storage capacity for storing data, thereby meeting increasing storage capacity requirements. Deduplication can greatly reduce the amount of storage needed to store data, and can also increase the efficiency of data access.

• Question 99:

  Which mirroring scenarios are mainly used in HyperMirror? (Multiple choices)

  A. Mirroring of two LUNs in this array
  B. Cooperate with the heterogeneous virtualization function to realize the mirroring of the LUN of the heterogeneous array and the array
  C. Cooperate with the heterogeneous virtualization function to realize the mirroring of two heterogeneous LUNs
  D. The mirrors of the two LUNs of the volume mirror are not under the same home controller
  A. Mirroring of two LUNs in this array
  B. Cooperate with the heterogeneous virtualization function to realize the mirroring of the LUN of the heterogeneous array and the array
  C. Cooperate with the heterogeneous virtualization function to realize the mirroring of two heterogeneous LUNs
