• Question 34:

  Create LUNs on an OceanStor V3 storage system. Set the initial space allocation policy to be automatic. Create LUN 1, and 80% of its space comes from the capacity tier. Create LUN 2 in the same storage pool. It can be concluded that 0% of LUN 2's space comes from the performance tier.

  A. TRUE B. FALSE

  Correct Answer: A

• Question 35:

  Which of the following are the basic principles of storage troubleshooting? (multiple choice)

  A. Locate the exterior first, then the interior

  B. First perform an alarm analysis, then use the replacement method

  C. First find the high-level alarm, then the low-level alarm

  D. Find the common first alarm, after the individual alarm

  Correct Answer: ACD

• Question 36:

  Which of the following is correct regarding the ext3 file system fault repair?

  A. Use the mount command to view the file system mount status is read-only

  B. mount the damaged file system, the direct implementation of fsck to repair

  C. should not be arbitrary on the normal operation of the fsck file system

  Correct Answer: B

• Question 37:

  Which statements are true about Huawei OceanStor V3 HyperMirror feature? (Multiple Choice)

  A. Create a mirror LUN for a common LUN. Due to internal information exchange, the LUN ID for hosts' read and write I/Os changes based on the information exchange result.

  B. A LUN stores 2 GB of data. Create a mirror LUN for this LUN. During the creation, the system automatically generates a copy. The total data amount of the copy and mirror LUN is 4 GB.

  C. HyperMirror can be configured for external LUNs, and external LUNs can be configured as HyperMirror copies.

  D. When configuring HyperMirror, its copies must come from different disk domains.

  Correct Answer: BCD

• Question 38:

  Which of the following is correct regarding the vmware link cloning function?

  A. Linking Cloned VMs behave just like cloned VMs

  B. Linked Clone A virtual machine is a complete clone of a cloned virtual machine

  C. Linked Clone The virtual machine is a standalone virtual machine

  D. Linked clone virtual machines take up less space than cloned virtual machines

  Correct Answer: D

• Question 39:

  In VSphere 5.0 and later, View Storage Accelerate (VSA) caches virtual machine disk data to EXSi hosts. It uses the content-based read cache (CBRC) in EXSi hosts, which no longer reads the entire operating system from the storage system. It reads the regular data block from the cache, thereby enhancing the performance of the virtual host.

  A. True

  B. False

  Correct Answer: A

• Question 40:

  A file system in a clustered NAS system performs heartbeat synchronization between nodes. When the heartbeat is interrupted, the N8000 cluster is split into multiple small groups, resulting in data loss. The N8000 provides a fencing function to avoid the occurrence of the split-brain issue. Which of the following descriptions of the role of fencing correct?

  A. Monitor GAB and check for changes in cluster members

  B. Guarantee a single view of the members of the cluster

  C. In the absence of a single cluster control, to prevent multiple nodes with Volume Manager to access shared storage

  D. cluster abnormal recovery automatically master node

  Correct Answer: ABC
