In this case, asynchronous remote replication is recommended.

A. FALSE

B. TRUE

Correct Answer: B

Question 2

In the HyperMetro active-active data center solution, which of the following statements about the static priority mode used for brain-split prevention is false?

A. If the non-preferred site fails, LUNS at the preferred site continue to provide services while LUNS at the non-preferred site stop providing services.

B. If a user powers off the storage system at the preferred site for maintenance purposes, the storage system at the non-preferred site immediately takes over all active-active services without service interruption.

C. If links between the storage systems are down, LUNS at the preferred site continue to provide services and those at the non-preferred site stop providing services.

D. If the storage system at the preferred site is faulty, the non-preferred site automatically takes over active-active services.

Correct Answer: D

Question 3

LAN-base backup networking is one of the most common networking modes.
Which are advantages of LAN-base backup networking? (Multiple Choice)

A. The backup performance is good.

B. Both control data and backup data are transmitted through the service network.

C. The performance of production hosts is not affected.

D. The existing network is fully utilized, reducing costs.

Question 4

Physical tape libraries have the following disadvantages: The mechanical failure rate is relatively high, and tapes are vulnerable to the adverse impact of the environment (temperature, humidity, and dusts).

A. FALSE

B. TRUE

Correct Answer: B

Question 5

Which of the following statements about deploying Huawei active-active data centers are true? (Multiple Choice)

A. Quorum software can be installed on a physical server or a virtual machine. The quorum server is connected to the two storage arrays in the active-active data centers over an IP network.

B. On the network layer, at least two independent GSLBs must be deployed at each site for load balancing between the two sites.

C. The transmission layer uses Huawei OptiX OSN series DWDM devices. Two wavelength division devices are deployed at each site.

D. The storage layer does not support the following practice: One OceanStor V3 storage system takes over LUNS from a third-party storage system. Then, a third-party LUN and a LUN on another OceanStor V3 storage system form active-active LUNs.

Correct Answer: A,C

Question 6

In the HyperMetro active-active data center solution, if a member LUN has bad blocks, which of the following statements is false?

A. Before repairing bad blocks, the read permission must be obtained and the local read permission for active-active pairs must be confirmed.

B. If irreparable bad blocks are read from a local LUN, the system uses data stored on the remote LUN to repair these bad blocks.

C. If repairable bad blocks are read from a local LUN, data is returned to the host, ensuring fast host response.

D. If irreparable bad blocks are read from a local LUN, a read error message is returned to the host.

Correct Answer: D

Question 7

An enterprise application was backed up as follows: On February 1 (Feb1), full backup of all files and directories was implemented. On February 2 (Feb2), 3 (Feb3), and 4 (Feb4), cumulative incremental backup was implemented. On February 5, service disks failed.
If the enterprise wane to restore the application to the state preserved on February 4, which backup files are needed?

A. Feb1+Feb3

B. Feb1+Feb2+Feb3+Feb4

C. Feb1+Feb2

D. Feb1+Feb4
