Begin to Test:

1. Which statement about the ROW technology for OceanStor V5 is true?

Block snapshots use the ROW technology

ROW-based snapshots do not have extra data copies, and therefore the performance is better.

One of the advantages of ROW is that it does not easily generate data fragments

Question 1 of 33

2. Which technology does FusionStorage HyperSnap run on?

COW

ROW

Question 2 of 33

3. The storage system monitors the responses to I/Os delivered to disks. If the responses exceed the upper limit, the RAID group experiences a read degrade to quickly respond to the hosts. This technology is called:

Online diagnosis

Slow disk detection

Rapid response to slow I/Os

Question 3 of 33

4. Which statement about the replication network between storage arrays in an active-active (HyperMetro) network is NOT true?

The active-active (HyperMetro) replication network supports the FC network

The active-active (HyperMetro) replication network supports the IP network

The active-active (HyperMetro) replication network bandwidth must be larger than the average service bandwidth

Each controller of active-active (HyperMetro) arrays has at least two redundant links

Question 4 of 33

5. A technology evenly distributes workloads to each disk, thereby preventing continuous hot data access from causing a premature failure of some disks. This technology is called

Wear leveling

Anti-wear leveling

Hot cache

Question 5 of 33

6. Which technique is used to protect end-to-end data integrity?

DIX+T10

CRC

SHA

Question 6 of 33

7. Which of the following statements is incorrect about the Active-active architecture of Dorado V6?

LUNs are not owned by any controller.

The logical paths of the host are Active-Active.

Load is balanced among controllers.

ALUA must be configured when the operating system_x27;s native multipathing software is used.

Question 7 of 33

8. What is the purpose of using sequential I/Os to overwrite all LUNs before testing Dorado performance?

To ensure correct deduplication and compression ratios

To ensure that all space of thin LUNs is allocated so read performance is close to that in actual scenarios

To provide better performance

Question 8 of 33

9. Which is the technology used for end-to-end protection of data integrity in the industry?

CRC

T10 PI

SHA
