1. Which of the following statement about recovery reconstruction of OceanStor V3 storage system is not correct?

can quickly recover valid data, not updated data does not need to be restored.

to complete recovery reconstruction, the need for data difference logging information.

Recovery reconstruction used in disk cannot be used normally, the RAID group is in a degraded state scenario.

incumbent disk suddenly failed, at this time will restore the reconstruction.

2. In OceanStor 18000 storage system, when the controller and hard disk box link failure, the controller will need access to the IO request is forwarded to another within the engine controller to complete access to the hard disk data.

TRUE

FALSE

3. Which of the following operations does not need quota checking when using files from OceanStor V3 quotas?

Add files

Check the read the file

Modify the file

Delete the file

4. If you want to buy a Huawei storage for video surveillance and backup archiving data services, it is suggested from which indicator to choose the appropriate Huawei storage devices?

IOPS

Bandwidth

Time Delay

CPU utilization

5. What are the common hardware failure of Huawei OceanStor series storage? (Multiple choice)

controller failure

hard drive failure

RAID failure

OceanStor Toolkit failure

6. There are several limitations in the use of Huawei OceanStor V3 SmartErase. Which of the following statements is correct?

Not support the data destruction of the source LUN which create a snapshot.

If storage resources of a LUN are from the SSD hard drive, carry out data destruction of the LUN, certainly can achieve the desired results.

Support data destruction of the snapshot LUN

support data destruction of Thin LUN

7. In Huawei OceanStor V3 WORM file system, the file signature is mainly used for checking the file integrity, but when the file Migration, the fingerprint information cannot follow the file Migration that need to calculate the fingerprint information in the file after the Migration is complete.

TRUE

FALSE

8. About the Huawei OceanStor V3 SmartQos I/O priority scheduling, which statement is correct? (Multiple Choice)

I/O priority is based on the LUN priority where IO located, the priority of LUN is made by users according to the importance of the business deployed on the LUN.

When the hard disk usage is high, in order to ensure the reliability of the hard drive, the system will give low priority I/O add delay to control, but try not to affect high-priority I/O.

I/O priority scheduling resources, including front-end host concurrent resource, the back-end hard disk concurrent resource, CPU computing resources and cache resources.

9. What requirements does Huawei OceanStor V3 synchronous remote replication have on the network, bandwidth and distance of disaster recovery? (Multiple Choice)

General Requirements metro network disaster recovery distance <200KM

Minimum connection bandwidth is not less than 64Mbps

network transmission delay <1ms (one-way)

network real bandwidth > business peak write IO Bandwidth

10. Which of the following statement is correct about FC and FCoE? (Multiple Choice)

FIP protocol is used in FC application scenarios.

FCoE uses enhanced Ethernet technology.

There are no FC-1, FC-2, and FC-3 layers in FCoE, all of which are replaced by Ethernet.

The function of FC-2 is data distribution, and the function of FC-1 is the encoding and decoding of data.
