An Oceanstor V3 system “alert” shows a message: “SPF [0] LOW Rx power alarm because Low Rx pow ALM of SFP0 is deleted/deflected. “The cause of the malfunction is:
- Equipment distribution voltage is insufficient, the device into a stream of electricity.
- The power module is not enough power to replace the power module.
- The voltage of the board is low or the light receiving power is low.
- Optical module port card loose connection.

-
Which of the following is the wrong mode of operation when checking on a problem with the VMFS datastore for ESXi5.5 using the VMware ondisk metadata analyzer (VOMA)? (Assume the LUN NAA ID is naa.60022a110009a8a800042e1800000000: 1).
- Turn off the power of all running virtual machines or migrate these virtual machines to another data store
- Use the esxcli storage vmfs extent list command to obtain the name and partition of the vmfs data store to be backed up after the provision of number of the supported devices.
- voma -m vmfs -f check -d /vmfs/devices/disks/naa.60022a110009a8a800042e1800000000:1
- voma -m vmfs -f check -d naa.60022a110009a8a800042e1800000000: 1
-
Which of the following IO model characteristics belong to random small IO? (Multiple choice.)
- OLTP
- OLAP
- VDI
- SPC-1
-
Which of the following is not part of the storage troubleshooting process?
- Manually clear the NMS alarm and turn off the alarm light.
- Observe the symptom and collect the fault information.
- Troubleshoot according to the “Event Reference” or “Troubleshooting” manual.
- Maintain the faulty environment and contact technical engineer for support.
-
In Huawei OceanStor 9000, which technologies are used to improve the performance? (Choose three.)
- SMB3 Multichannel is used to bring multi-core CPU and bandwidth resources of clients into full play, thereby significantly improving the performance.
- The OceanStor DFS can combine write I/Os to a disk into large sequential I/Os, boosting system performance.
- Internal file replication can be completed at a high speed in the system, without involving the client.
- The back-end network can be established based on 10GE or PCIe. High-speed connections between nodes reduce internal latency, thereby offering superb performance.
-
Suppose the initial amount of backup data is 1TB, the average amount of increment data for every day is 10GB. The backup policy is configured as the following:
One full backup on every Monday,
One incremental backup for each day from Tuesday to Sunday,
The data retention period is four weeks for both full backup and incremental backup.
The back-end capacity for four weeks later should be no less than (Ignore deduplication, redundancy ratio):
- 4940G
- 4280G
- 5940G
- 5280G
-
Which of the following description is correct about simpana backup software snapshot? (Multiple choice.)
- Pause the app before the snapshot, go to the hardware storage snapshot to trigger a common snapshot with application consistency.
- Backup software snapshot function can automatically find the storage volume of the file system, database, mail system.
- Background snapshots can be indexed to ensure application recovery and small particle recovery.
- Snapshots backup can be offline, the backup server almost has no impact.
-
When planning an active-active disaster recovery solution, the business end adopts the cluster application. Which of the following clusters is the application cluster?
- mSCS
- Oracle RAC
- HACMP
- SQL server
-
Which of the following is correct about Huawei OceanStor v3 unified storage system? (Multiple choice.)
- Standalone SAN engine and stand-alone file engine
- Parallel dual-stack by way of parallel support (SAN) and file system (NAS)
- Use unified storage pool technology
- file system can achieve deduplication data compression function
-
Disaster recovery project information research mainly includes information about who, what, and why. What is the following information background? (multiple choice)
- A bank has more than XX customers and XX corporate customers.
- Data loss will be huge and business disruption may result in significant financial loss.
- Business interruption has a huge impact, and the interruption time in business deployment is less than 2 hours.
- Clients want to build two live-action data centers in the same city to realize the key business activities such as RTO 2.
-
An enterprise buys a set of Huawei OceanStor 9000 storage systems. Some of the enterprise’s basic software is stored in a directory, and users can access enjoy/it. In order to facilitate the operation, users should not enter the account password, and the basic software directory is set to NFS enjoy, you should check the share of the “guest enabled” option.
- True
- False
Explanation:NFS does not have guest users this option.
-
In preparation for disaster recovery design, which of the following is correct?
- Use the same type of disk as the master
- Raid should be set the same as the master
- The capacity of Lun and primary LUN is the same
- Use the same number of disks as the master
-
Which statement about the RMAN restore and recovery is wrong?
- Restore (restore) refers to the previously generated backup set, get one or more objects, and then set to restore these objects.
- Recovery (recovery) is a database that is consistent with the given point in time to ensure that this database can be opened.
- Usually restored content lags behind the latest database SCN, so you need to ensure consistency through the restoration of the database.
- The restored data files can use archived logs and online logs to complete the recovery.
-
Huawei Oceanstor 9000 provides a single file system to the outside through the unified file system namespace management. Which of the following description is correct? (Multiple choice.)
- The namespace is automatically created when HUAWEI OceanStor 9000 is started with the same name as the system namespace.
- Namespaces as the root directory of the entire system can not be shared and visited, only if ask the subdirectories below it can be shared and visited.
- A unified namespace provide users with a unified storage resource pool to achieve the centralized management of storage space and distribution.
- Each file share directory is a subdirectory of the namespace.
