In the OceanStor VIS6600T dual-redundant switch network environment, using OceanStor Toolkit inspection found that "multi-path state detection "does not pass the inspection report. It is found that there are two routes in the 4 paths of the VIS6600T device's 0 node to each LUN of the array. The path status is disabled. According to the analysis, the switch port connected to port 0 of port A0 of node 0 on node 0 of the VIS6600T is visible on the optical switch. The received optical power is much lower than the rated power of the optical module. What actions should be taken to fix this?
A. Replacing the optical module of port 0 in slot A0 of node 0.
B. Replacing the light of the P0 port in the A0 slot of 0 node.
C. Replacing the optical module of the port connected to port 0 of the corresponding 0-node A0 slot on the switch.
D. Reseat the FC interface card corresponding to slot 0 of node A0.
Which of the following is correcting regarding the read and write performance of the Huawei Oceanstor 9000 node, from highest to lowest?
A. P25 Node SSD Hard Drive> P25 Node SAS Hard Drive> P36 Node SATA Hard Drive> P12 SATA Hard Drive> C36 SATA Hard Drive
B. P25 Node SAS Hard Drive> P25 Node SSD Hard Drive> P36 Node SATA Hard Drive> P12 SATA Hard Drive> C36 SATA Hard Drive
C. P25 Node SSD Hard Drive> P25 Node SAS Hard Drive> P36 Node> C36 SATA Hard Drive> P12 SATA Hard Drive
D. P25 Node SSD Hard Drive> P25 Node SAS Hard Drive> C36 SATA Hard Drive> P36 Node SATA Hard Drive> P12 SATA Hard Drive
Which description of the N8000 Clustered NAS file system snapshot features and their application is wrong?
A. Snapshot file system can be dedicated as a separate space to the client.
B. For a file system can create multiple snapshots, support snapshots of the snapshot
C. Snapshot file system provides only read-only access to external, it cannot provide write operations
D. File System Snapshot Instantly copy the source file system completely available copy, when due to viruses or man-made misuse and other causes of the original file system is not available, the rollback of the snapshot can restore the original file system.
Which of the following statements about the info stamper in an OceanStor 9000 storage system is not correct?
A. Oceanstor 9000 uses COW technology for metadata
B. Oceanstor 9000 uses ROW technology for data
C. Between snapshots of different versions, there is common data between the snapshot and the current year
D. According to the snapshot version data objects have a backward dependency, so when reading the snapshot data, according to the object dependencies, the system determines from which object to
read.
The peak write bandwidth for an application is 10MB / S, with an average write latency of 200KB / s and an average write IO size of 4KB (bandwidth utilization of 70%). If you need to use OceanStor V3 storage array to implement data disaster recovery and set it as asynchronous replication mode, you need the minimum network-wide bandwidth of which of the following?
A. 3.2Mbps
B. 128Mbps
C. 114 Mbps
D. 18 Mbps
Which of the following is correct about the OLAP business load characteristics? (multiple choice)
A. Read operation for sequential read
B. A single IO is large, the typical value of 64KB ~ 1MB
C. No IO write operation
D. Usually data is not overwritten by the cycle or days to measure
True or False, one project adopts the OceanStor 18500 to achieve the performance of 50,000 IOPS. Enable the SmartTier feature and configure the Layer 3 Tier configuration disk computing, high-performance layer up to 30,000 IOPS, the performance layer can reach 20,000 IOPS, capacity can reach 10,000 IOPS.

Which of the following is correct regarding the Oracle RAC deployment installed Grid package? (multiple choice)
A. To check the cluster node use the command: olsnodes -n
B. To check the cluster status use the command: crsctl check cluster -all crsctl check crs
C. To check cluterware resource status use the command: crsctl stat ser -t
D. To check oracle ASM operating status use the command: ocrcheck
An enterprise has purchased two sets of HUAWEI OceanStor 9000 devices. To ensure the security of the data, one set provides storage for the production site and the other set is on the disaster recovery site to provide data redundancy. If the two Huawei Oceanstor 9000 storage system are to establish remote replication, which of the following is wrong?
A. Recovery strategy supports both manual and automatic methods
B. synchronization rates are high, medium and low third gear
C. The type of synchronization is manual, the timing is started after the synchronization starts, and the timing is delayed after the synchronization is completed
D. When the synchronization type is set to manual, there is no need to set the timing duration If the synchronization type is set to be either custom waiting when synchronization starts or when waiting for customization after synchronization, you need to set the timing duration
When cache mirroring is enabled for the two controllers of an OceanStor V3 storage system, the two controllers have identical cache data and the failure of either controller does not affect system services.
A. TRUE
B. FALSE
