• Question 171:

  Regarding the four disaster recovery modes of HyperMetro, Hot Standby, Warm Standby, and Cold Standby, is the following statement wrong?

  A. HyperMetro technology can realize that both the main and backup data centers provide services to the outside world. During normal operation, the business of the two data centers can Do load sharing based on weights, there is no difference between master and backup, and respond to some users separately. The weight can be divided by region, or number According to the center's service capacity or external bandwidth
  B. Warm standby technology. When a data center failure causes the service to become unavailable, within the specified RTO time, you can Automatically switch the service to a backup data center
  C. The hot standby business is responded by the main data center. When a data center failure causes the business to be unavailable, the Within RTO time, the service can be automatically switched to the backup data center
  D. The biggest feature of multi-activity is that it will not cause waste of resources in the data center, and the data center carries application business operations.
  B. Warm standby technology. When a data center failure causes the service to become unavailable, within the specified RTO time, you can Automatically switch the service to a backup data center

  Explanation

  Analysis: The warm standby technology is implemented on the basis of the active and standby data centers, provided that there are two active and standby data centers. The standby data center is deployed for warm standby, and application

  services are responded to by the primary data center.

  When the service is unavailable, it is necessary to realize the overall switching of the data center within the specified RTO time. When realizing the main data When the center switches, it is necessary to disconnect the main data center

  routing link and connect the backup data center routing link to ensure the same time There is only one data center online. The warm-up technology is still a manual method, and someone needs to be on duty 24 hours to complete the

  operation.

  The work effect is low.

• Question 172:

  Match the RAID level with the characteristics. (1) RAID 0 (2) RAID 5 (3) RAID 10 (4) RAID 6 (a) Cost effective (b) Allows double disk failure (c) Highest performance (d) No data protection

  A. 1-a; 2-d; 3-b; 4-c
  B. 1-d; 2-a; 3-c; 4-b
  C. 1-d; 2-a; 3-b; 4-c
  D. 1-a; 2-b; 3-c; 4-d
  B. 1-d; 2-a; 3-c; 4-b

• Question 173:

  What is the correct description of the advantages of Huawei RAID 2.0+?

  A. The data is automatically and evenly distributed on the hard disks in the storage pool to avoid uneven heating and cooling of the hard disk, thereby reducing the storage system Overall failure rate
  B. Overcome the performance bottleneck of the traditional RAID reconstruction target disk (hot spare disk), making the reconstruction bandwidth write bandwidth no longer It becomes the bottleneck of the reconstruction speed, which greatly improves the reconstruction speed, reduces the probability of double-disk failure, and improves the storage system.
  C. There is no write penalty in RAID2.0+, which overcomes the write penalty in RAID 5 and RAID 6 levels in traditional RAID technology The impact of the penalty on the write performance of the LUN has greatly improved the performance of the LUN
  D. The data on a single LUN is distributed to many different hard disks, avoiding hard disk hot spots, making single LUN performance and The capacity has been greatly improved

  A. Statements 1 and 2 are both true.
  B. Statement 1 is true and statement 2 is false.
  C. Statement 1 is false and statement 2 is true.
  D. Both statements 1 and 2 are false.
  C. Statement 1 is false and statement 2 is true.

  Explanation

• Question 176:

  Which statements are true about RAID 2.0+? (Select All that Apply)

  A. An extent is a block of a fixed size in a chunk group (4 KB by default).
  B. A chunk group is a logical set of chunks on different disks.
  C. Chunks, which are blocks obtained by dividing each disk at a fixed size, are basic units of a RAID group
  D. A chunk group is the minimum unit for applying for and releasing space in a storage pool
  A. An extent is a block of a fixed size in a chunk group (4 KB by default).
  C. Chunks, which are blocks obtained by dividing each disk at a fixed size, are basic units of a RAID group

  Explanation

• Question 177:

  Two CKs in a CKG of RAID2.0+ can come from the same hard disk.

  A. TRUE
  B. FALSE
  B. FALSE

  ---

  Explanation

  CKG is a logical storage unit composed of CKs from different hard drives in the same DG according to the RAID algorithm. The smallest unit of resources allocated by the pool from the hard disk domain.
