Huawei Huawei Certifications H13-622 Questions & Answers

• Question 161:

  In the cluster communication architecture employed by an N8500 clustered NAS system, modules such as the resource agent, HAD, GAB, and Low Latency Transport (LLT) must collaborate to implement cluster communication.

  Which of the following statements about the work mechanisms of these modules are correct? (Select three)

  A. The agent monitors the resources of each system and provides the status information for the HAD of each machine.

  B. If a cluster node is abnormal or faulty, the HAD takes correct actions, for example, performing a failover.

  C. The GAB implements a point-to-point communication mechanism. The master node sends the other cluster nodes the information that needs to be synchronized.

  D. LLT is a MAC-layer protocol unrelated to IP layer.

  Correct Answer: ABD

• Question 162:

  An N8500 clustered NAS system is equipped with four engine nodes and each engine node provides four service network ports. How many virtual IP addresses must be planned for the N8500?

  B. 16

  C. 17

  D. 18

  Correct Answer: C

• Question 163:

  There are four types of ports on the N8500 clustered NAS engine nodes: heartbeat port, management port, service port, and storage port. Which of the following statements about the port types in the figure are correct? (Select two.)

  

  A. 1 indicates a service port.

  B. 2 indicates a storage port.

  C. 3 indicates a heartbeat port.

  D. 4 indicates a management port.

  Correct Answer: BD

• Question 164:

  A big data processing system involves five layers: data collection, data storage, data processing, data analysis, and data application and presentation. Which of the following statements about the five layers are correct? (Select two)

  A. Data collection is implemented based on data sources. Attention must be paid to the use of structured and unstructured database technologies.

  B. Data storage resolves the massive data storage issue. Attention must be paid to data variety and heterogeneous data convergence.

  C. Data processing features high velocity. Attention must be paid to the parallel computing technology.

  D. Data analysis and application highlight data value. Attention must be paid attention to data mining, business intelligence, and data search.

  Correct Answer: CD

• Question 165:

  The HUAWEI OceanStor Toolkit V100R001 is used for preventive maintenance. The preventive maintenance wizard does not include which of the following?

  A. Select Devices

  B. Select Check Items

  C. Set Check Policy

  D. Export Check Policy

  Correct Answer: D

• Question 166:

  Which of the following statements about IP address planning for the N8500 clustered NAS storage systems is incorrect?

  A. Each service network port, management network port on an engine node, and management network port on a storage unit must have a physical IP address.

  B. Each service network port and management network port on an engine node must have a virtual IP address.

  C. Ensure that the physical IP address and virtual IP address of each port reside on the same network segment.

  D. It is recommended that the console IP address reside on the same network segment as the service network.

  Correct Answer: B

• Question 167:

  Which of the following statements about the performance optimization check items of the N8500 clustered NAS storage systems are correct? (Select three)

  A. Check whether the BBUs are faulty. If only one BBU is faulty, the current write policy of LUNs changes to write through.

  B. Log in to the ISM and check whether alarms indicating slow disk response exist.

  C. Check on the ISM whether bit errors exist on Fibre Channel ports.

  D. Check whether front-end service ports are functioning at the optimal rate. For example, check whether the port rate is 4 Gbit/s when the bandwidth is 8 Gbit/s.

  Correct Answer: BCD
