H13-623 by Huawei Valid Free Exam Practice Test

Question 1

File-level deduplication is also known as single instance storage (SIS). Based on indexes, file-level deduplication checks and compares the attributes of a file that needs to be stored with those of files that have been stored. If the file has not been stored, file-level deduplication stores the file and updates indexes.
Otherwise, file-level deduplication only stores the pointers that point to the existing file.

A. FALSE B. TRUE

Correct Answer: B

Question 2

Which is not one of the three elements in information survey of Huawei Active/Passive Disaster Recovery Solution?

A. Project background B. Customer requirements and summary C. Project implementation plan D. Network environment information

Correct Answer: C

Question 3

Suppose that a customer that adopts the Huawei Network-Layer Full-Sized Snapshot Solution starts creating a snapshot for the source volume at 9:00 am, and the snapshot finishes being created at 9:10 am. During the snapshot creation, some data is written to the source volume. Based on the preceding conditions, which of the following statements is correct?

A. Data in the snapshot volume is the same as that in the source volume at 9:00 am. B. The snapshot volume is a physical copy of the source volume generated at 9:00 am. C. Data in the snapshot volume is the incremental data generated during 9:00 am to 9:10 am in the source volume. D. Data in the snapshot volume is the same as that in the source volume at 09:10 am.

Correct Answer: A

Question 4

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

Correct Answer: B

Question 5

Which are possible causes for an enterprise to use virtual tape libraries as the backup media? (Multiple Choice)

A. The original tape storage system architecture does not need to be changed. B. The capacity scalability is better than that of physical tape libraries. C. The initial cost of unit storage is lower than that of physical tape libraries. D. The read and write performance is higher than that of physical tape libraries.

Correct Answer: A,D

Question 6

Which of the following are Huawei DR Solutions? (Multiple Choice)

A. Geo-Redundant Solution B. Active-Active DC Solution C. Active-Passive DR Solution D. Local HA Solution

Correct Answer: A,B,C,D

Question 7

In the Cascading Replication DR Solution, the synchronization + asynchronization and asynchronization + asynchronization modes are both supported.

A. FALSE B. TRUE

Correct Answer: B

Question 8

Which of the following can be configured in the backup management system? (Multiple Choice)

A. Hosts to be backed up B. Contents to be backed up C. Backup network D. Data backup Destination E. Backup time

Correct Answer: A,B,D,E

Question 9

Which function is not supported by a backup service node?

A. To write the job index information and backup task into the media B. To transfer data between the client and backup management node C. To maintain the index information and index cache information about all jobs on the service node D. To write backup software data and read recovery data

Correct Answer: B

Question 10

Which of the following are Huawei remote DR Solutions? (Multiple Choice)

A. Geo-Redundant Solution B. Active-Active DC Solution C. Active-Passive DR Solution D. Local HA Solution

Correct Answer: A,C

Question 11

Which of the following statements about client deduplication and media deduplication are true? (Multiple Choice)

A. Media deduplication saves bandwidth resources and does not consume resources at the source end. B. Client deduplication consumes resources at the source end but saves bandwidth resources. C. Client deduplication is implemented as follows: At the source end, hash comparison is performed for data blocks to be transmitted. If a data block has been transmitted, only the corresponding hash index value will be transmitted. D. In terms of media deduplication, in-line processing provides higher data transmission performance than post processing.

Correct Answer: B,C

Question 12

Which is the correct process for installing CommServe?

A. Install the .NET Framework. > Install databases. > Select a proper firewall configuration. > Configure DR paths. B. Select a proper firewall configuration. > Install the .NET Framework. > Install databases. > Configure DR paths. C. Install the .NET Framework. > Select a proper firewall configuration. > Install databases. > Configure DR paths. D. Install the .NET Framework. > Select a proper firewall configuration. > Configure DR paths. > Install databases.

Correct Answer: C

Question 13

Suppose that a customer has a third-part storage system and wants to set up a Local HA Solution. Is that feasible to buy the OceanStor 5600 V3 and only HyperMirror license to serve the purpose?

A. No. HyperMirror and HyperCopy are both required. B. No. HyperMirror and SmartVirtualization are both required. C. Yes. All conditions required for the solution are met. D. No. HyperMirror and HyperClone are both required.

Correct Answer: B

Question 14

Huawei's end-to-end active-active data center solution is divided into six logical layers, namely, storage, computing, application, network, transmission, and security layers. Which are key points in designing these layers? (Multiple Choice)

A. The computing layer uses virtualization platforms such as FusionSphere and VMware to provide cross-data-center clustering, thereby enabling multiple mission-critical applications to run in active-active mode. B. The transmission layer employs optimization approaches such as dispersion compensation to ensure the minimum latency on the transmission layer. C. The security layer uses Huawei USG series to provide security protection functions such as FW and IDS for data centers. D. The storage layer uses the FastWrite function to reduce two round trips to one for each standard write I/O, thereby improving the write performance.

Correct Answer: A,B,C,D
