Question 10 of 50

11. An enterprise has an online transaction system and an email system in a 30 TB storage resource pool. The backup system has created three 10 TB Thin LUNs. Since the company is just starting out, the online transaction system and the email system have very little data. The backup system needs to import about 20 TB of old data, which exceeds the Thin LUN size, resulting in write failure.

True

False

Question 11 of 50

12. A customer's business application uses a Huawei OceanStor hybrid flash storage system with three pools, all of which are 8D+1P RAID5. One day, a business interruption occurred, and engineers found some scenarios that caused the failure by analyzing the logs.
Which of the following scenarios will cause interruption of host access to storage services? (Multiple choice)

In a fully redundant network environment, the master controller is reset.

The POOL where the service is located contains only ThinLUNs and no snapshots, LIN copies, clones, or services are configured. The log contains information indicating that the POOL space is full.

When the BST (bad track mark) function is disabled, BST bad tracks appear on the LUN.

The log contains the following printouts: [2014-01-19 08:04:40] [Receive a disk-fault event of the disk (328) of pool (2) from Ctrl.] [2014-01-19 08:40:35] [Receive a disk-fault event of the disk (613) of pool (3) from Ctrl.]

Question 12 of 50

13. Which of the following descriptions of HyperMetro's arbitration server mode is wrong? (Multiple choice)

It is recommended that the arbitration server be deployed in a data center with good storage performance. When arbitration is required, high-performance storage can more easily win and continue to provide services.

In arbitration server mode, if a site has priority in obtaining genres, you can also configure site priority. The priority array has the priority to win the genre. If the heartbeat is interrupted but other functions are normal, the priority array will win the genre.

The active-active domain contains array A, array B, and the arbitration server. If array A and the arbitration server fail at the same time, array B survives and continues to provide services.

If the arbitration server fails, the business will continue to operate normally.

Question 13 of 50

14. Which of the following businesses can use SmartTier features to improve storage system performance and reduce user costs? (Multiple choice)

ERP

Data Mining

Online shopping

Data warehouse

Question 14 of 50

15. Which of the following descriptions of high-performance technology in HyperMetro is correct? (Multiple choice)

In the preferred array mode, when the host service accesses the space, I/O will only be load-balanced and delivered on the preferred array path set by the user. If this mode is configured, the arbitration server mode cannot be configured.

HyperMetro uses the host I/O granularity to add distributed range locks to the LBA intervals between host I/O accesses for concurrent mutual exclusion, thereby achieving the purpose of two-way real-time synchronization. This solution can save unnecessary data transmission bandwidth between arrays and effectively reduce the number of data transmissions.

HyperMetro optimizes the data transmission between arrays at the protocol level through the FastWrite function and applies the First Burst Enabled function of the SCSI protocol, reducing the number of link transmission intersections for write data by half.

Simplified copy uses hardware chips to quickly identify the data copy source. Find the zero data, and during the copy process, specially mark the all-zero data, and only transmit a small special page to the other end instead of the full data.

16. Distributed storage, file storage and object storage can share storage space with block storage and switch freely.

Question 16 of 50

17. Which of the following statements about Thin LUN are correct? (Multiple choice)

Thin LUN cannot be directly converted to Thick LUN

All LUNs in a storage pool need to enable SmartThin.

Thin LUN consumes very little storage capacity when it is created.

Question 17 of 50

The business data is a small file, but the total capacity is large.
Based on this scenario, when formulating a backup strategy using Huawei's integrated data protection device, which of the following statements is correct? (Multiple choice)

To avoid peak business hours, backup can be performed between 23:00 and 6:00

In the case of massive small files, volume backup is not suitable
