Question 61
What are the several recovery mode drills of Huawei Replication Director disaster recovery?(Multiple choice.)
A. Planned Migration
B. Failover
C. Business Recovery
D. fault recovery
Question 62
Which of the following feature is correct about the OceanStor V3 volume mirroring? (Multiple choice.)
A. After creating a mirrored volume for a normal LUN, the server read-write IO results in a change as a result of internal information exchange.
B. The amount of data actually stored on a LUN is 2G, the total copy of the data is 4G. A volume image is created for the LUN, the LUN is mirrored when the copy is generated during system creation.
C. You can configure a volume mirror for external LUNs or configure external LUNs as mirror copies.
D. When configuring volume mirroring, mirror copies are required from different disk domains.
Question 63
Using non-deduplication storage based on the disk library strategy, data recovery fails after the data life of the backup has expired:
A. Client corresponding partition insufficient space
B. Client One or more simpana services are not started
C. The storage policy checked enable managed disk space for disk library option, leading to the disk's thresholds from the effectively managed disk space.
D. The client is abnormal with cs or MA communication.
Question 64
What are the design information research activities in the backup solution? (Multiple choice.)
A. Customer needs collection and refining
B. Backup capacity calculation
C. Project background research
D. Network environment is collected
Question 65
What are the ways of load balance cluster software in the most basic functions, the load balancing on Oracle rac? (Multiple choice.)
A. Client Balance
B. Cluster nodes balanced
C. Service layer balance
D. Instance load
Question 66
In the scenario of protecting the database, the slave uses the virtual snapshot method to verify the services of the production end and the DR-side and discover the data of the DR on the disaster recovery end. What are the possible reasons that the library can not start normally? (Multiple choice.)
A. After a snapshot of the LUN of the redundancy site is created, the snapshot is not activated at the same time.
B. Disaster recovery side of the data stored in the cache, not yet written to the hard disk.
C. When creating a snapshot on the disaster recovery end LUN, the production end is copying data to the disaster recovery end.
D. The production end and disaster recovery end adopt the disaster recovery solution of incremental LUN copy, and the incremental data link is abnormal during
Question 67
The OceanStor V3 storage system has 96 hard disks in one hard disk domain. To maximize the performance of the hard disk, it is recommended to use the LUNs in the hard disk domain.The total number of hard disks is not less than:
A. 96
B. 4
C. 32
D. 12
Question 68
Which of the following statements about multi-planar system design of Huawei Oceanstor unified storage system is correct?
A. The service plane uses GE channels for data transmission.
B. The service plane connects the host IO channel, disk IO channel and GE switching channel.
C. Plane redundancy between each other, when the business plane fails, allowing the use of control plane transmission services.
D. When the GE switch channel fails, you can use the PCIe switch channel as a backup data transmission channel.
Question 69
If the main service is normal in the simpana-based backup solution, view the following log:
A. CVMA. log
B. CVNetcheck. log
C. CVService. log
D. CVD. Log
Question 70
Which of the following statement about RAID 2.0 is correct? (Multiple choice.)
A. The hard disk is divided into chunk.
B. Lun consists of extend or grain
C. A CKG chunk may come from the same hard disk.
D. Chunk in a CKG may come from a different storage pool.
