Options:

TRUE

FALSE

Answer

Questions # 78:

Regarding the characteristics of the four disaster recovery modes of active-active, hot standby, warm standby, and cold standby, what is wrong in the following statement?

Options:

The data center using cold standby mode has a long RTO and is unpredictable

The data center adopting the HyperMetro mode has the shortest RTO time

When a data center failure causes the service to become unavailable, the hot standby and active-active modes can be automatically switched by software

Services, while the warm standby mode requires manual intervention, and the cold standby mode requires manual intervention

Hot standby mode requires the highest software cost

Questions # 79:

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

Options:

The deduplication function is used together with SmartCache to accelerate performance

The taken-over heterogeneous array LUN supports block-level deduplication

Deduplication and remote replication cannot coexist on the same LUN

When the LUN is created, the deduplicated LUN is selected and cannot be restored to the state without deduplication.

Answer

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.

Questions # 80:

Regarding the steps of SAN synchronous replication, what is the correct order?

(1) The production storage receives the host write request. HyperReplication logs the request. Only the place is recorded in the log

Address information, without recording data content.

(2) HyperReplication waits for both the primary LUN and secondary LUN write processing results to be returned. If both are written successfully, clear

Log; otherwise keep the log, enter the abnormal disconnection state, and then copy the corresponding number of the log address again when starting synchronization

According to the block.

(3) Write the request to the master LUN and slave LUN. Normally, the LUN is in the write-back state, and the data will be written

Cache.

(4) Return the processing result of the host write request, which is subject to the processing result of the write master LUN.

Options:

(1) (3) (2) (4)

(1) (2) (3) (4)

(2) (1) (3) (4)

(4) (2) (3) (1)
