Huawei HCIE-Storage V3.0 Sample Questions:

1. In order to improve system business performance, fusionstorage forms a shared distribution of SSDs on each storage node: cache resource pool, a part of which is used as the cache area of the main memory machine, to ensure that data passes through this part of the cache before entering the HDD mechanical disk. Cache data to reduce latency, usually called ________cache.

2. Which of the following statements about high performance technology in HyperMetro are true?
(Multiple Choice)

A) The streamlined copy quickly identifies the source of the data copy through the hardware chip.Find the zero data. During the copying process, for the special identification of all zero data, only a small special page is transmitted to the opposite end, and the full amount is no longer transmitted.
B) HyperMetro uses the granularity of host I/O to perform concurrent and mutual exclusion on the LBA interval between host I/O accesses and distributed range locks, so as to achieve the purpose of two-way real-time synchronization. This solution can save unnecessary data transmission between arrays.
Auxiliary bandwidth, and effectively reduce the number of data transmissions.
C) In the preferred array mode, when the host service accesses time, the I/O will only be distributed in load balance on the preferred array path set by the user. Arbiter server mode cannot be configured when this mode is configured.
D) 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, which reduces the link transmission intersection of the write data by half.

3. Windows supports two disk partition modes, MBR and GPT. For GPI disks, which of the following options are correct?

A) There is a backup disk partition strip at the end of the disk
B) The maximum size of a single partition is 2TB
C) Performance is not as stable as MBR disks
D) Allows up to 64 partitions per disk

4. A customer's Huawei OceanStor hybrid flash storage array experienced a RAID (Raid5) group failure. After the engineer restored the RAID group to a degraded state, the RAID group began to be reconstructed, but the reconstruction failed many times. Which of the following statements is correct? (Multiple Choice)

A) The RAID group cannot be restored by restoring the hard drive that failed first.
B) The RAID group is recovered by recovering the first failed hard disk, and the recovered data is unavailable.
C) The RAID group can be restored by restoring the hard drive that failed first.
D) The RAID group is recovered by recovering the first failed hard disk, and the recovered data will be lost for a period.

5. The engineer completed the preliminary inspection and configuration in strict accordance with the Huawei OceanStor 9000 product software installation and operation instructions. Some exceptions occurred during the software deployment process. Which of the following methods is appropriate? (Multiple Choice)

A) If the error "Failed to configure the operating system" occurs, check the node /var/log partition and clean up the partition to initialize the system before redeploying the software.
B) After the deployment fails, you can run the sh/opt/huawei/deploy/script/clean.sh command on each node to initialize the system and restart the software deployment.
C) After some exceptions are detected, reboot all nodes to recover, and then reinstall OceanStor Toolkit to start software deployment again.
D) After the deployment fails, restart the deployment after reinstalling the deploy deployment package.
