Which of the following is not a step in the storage troubleshooting process?
- A . Observe the fault phenomenon and collect fault information
- B . Perform troubleshooting according to the Event Reference or Troubleshooting manual
- C . Manually clear the network management alarm to turn off the device alarm light
- D . Maintain the fault environment and contact technical support engineers
In Huawei’s data center virtualization solution, which of the following software can be used for disaster recovery management? (Multiple choice)
- A . UltraVR
- B . eBackup
- C . eReplication
- D . OceanProtect
A customer deploys a storage array in two cities, and uses asynchronous remote replication networking between the two storage arrays. Which of the following statements are correct? (Multiple choice)
- A . The snapshots automatically created by asynchronous remote replication can be either private snapshots or public snapshots.
- B . In the disaster recovery drill scenario, it is recommended to create a virtual snapshot of the slave LUN and map it to the host for access.
- C . The number of LUNs in a consistency group should be as small as possible. Only LUNs that have write dependencies on the same application should be placed in a consistency group.
- D . In the remote replication link networking mode, parallel networking has better performance than cross networking.
Which of the following is not a processing step for online deduplication in OceanProtect professional backup storage?
- A . Computing fingerprints
- B . Fixed-length sharding
- C . Fingerprint table comparison
- D . Return fingerprint index
An IT engineer took on a project to deploy distributed storage for a bank and determined that the networking solution would be Huawei’s intelligent distributed storage converged service networking solution, with independent switches used for the management network, business network, and storage network.
In the early stages of a project, the engineer will conduct a site survey. Which of the following options should he consider? (Multiple choice)
- A . Check whether the temperature and humidity in the equipment room meet the equipment environment requirements
- B . Power on and off distributed storage devices
- C . Draw the floor plan of the computer room and determine the schematic diagram for equipment placement
- D . Plan IP addresses according to the networking plan and output the IP address allocation table
When Engineer A was implementing storage delivery, he was unable to scan the LUN on the Linux service host. Which of the following possible causes is wrong?
- A . The host does not have multipath software installed
- B . Storage pool failure
- C . Zone configuration error
- D . Link failure
In Huawei’s OceanStor Dorado all-flash storage system, SmartQos flow control management is implemented through three parts: I/O classification queue management, token distribution, and dequeue control of the controlled object.
- A . True
- B . False
The two-site three-center disaster recovery solution adopts the "active-active + synchronous + asynchronous parallel" networking architecture. Which of the following descriptions of this architecture are correct? (Multiple choice)
- A . Both the active-active LUN write operation and the intra-city synchronous replication write operation are returned, and then the write IO operation completion is returned to the host.
- B . The active-active LUN writes the write request to the active-active data LUN in the production center. At the same time, the data sent to the A array in the production center is synchronized in real time to the C array in the disaster recovery center in the same city.
- C . The production host sends a write request to the active-active LUN.
- D . Start periodic synchronization of the data of LUN1 of storage array B at time point t1 to the differential data of LUN2 of storage array D at time point t2 in the background
When all BBUs of the storage controller are damaged, the controller will automatically set the 10 write policy to write-through and lock it to ensure data reliability. It cannot be forced to change to write-back before the fault is recovered.
- A . True
- B . False
In the CLI, you can use the command completion function by pressing the "()" key or the space bar.
