True or False, with a client using the SMB 1.0 / 2.0 / 2.1 / 3.0 protocol to perform file replication inside a Huawei OceanStor 9000, it does not need to pass through the client, but can be done directly to the system.
A. True
B. False
Client 1 attempts to read file X from an OceanStor 9000, and node A responds to the read request. Which statements are true about the process of reading file x? (Choose two.)
A. If the system detects that node B has cached file X, client 1 can directly read the file from node B.
B. If the system detects that node B has cached file X, node A can directly read the file from node B.
C. After processing the file read request initiated by client 1, the system retains file X on both node A and node B.
D. If the system detects that node A has cached file X, only data of file X is cached on node A but the parity data is not cached on node A.
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 the synchronization.
Which command will modify vg01 into vg - app without affecting the HPUX 11.31 system volume group?
A. can not sit down
B. vgchange
C. vgexport mkdir mknod vgimport
D. vgremove mkdir mknod vgcreate
Which of the following is not a disaster recovery manual restart configuration necessary to restore the production system (Multiple choice.)
A. Stop the current production business
B. Add the remote device to the original production array
C. With the disaster recovery array as the master LUN and the original production array as the slave LUN, create the remote replication relationship between the DR and the production end and wait for the initial synchronization to be completed.
D. Make an incremental synchronization.
E. Delete the original production array consistency group.
You are building out a large-scale FC storage network where all switches are cascaded. When multiple FC switches are cascaded, which of the following scenarios will cause the switch to isolate E_prot port? (multiple choice)
A. FC switch Zone conflict
B. FC switch IP address conflict
C. FC Switch Switch Name conflict
D. FC switch domain ID conflict
What is the correct description of the Huawei Oceanstor 9000 read and write process?
A. The CA is responsible for initiating the metadata query
B. If the global cache read hit, read from the global cache without having to go to the OBS to read the stripe data
C. Reading data, the MDS is responsible for assembling the slitting data
D. When writing data, calculate the redundant data by MDS
When planning a dual-active disaster recovery solution, the business end adopts the cluster application. Which of the following cluster applications can support the AA working mode?
A. MSCS
B. oracle RAC
C. HACMP
D. SQL server
Using Simpana to achieve a complete Exchange backup requires at least which of the following components? (Multiple choice)
A. offline mining
B. database
C. mailbox D. public folder
An N8000 file system can be used when offline command to query file system flag:
echo "8192B.p S" | fsdb -t vxfs / dev / vx / rdsk / sfsdg / sfsvol | grep flag
Where sfsvol is the name of the file system and may appear as flsgs 0 mod 0 Clean 3c or flags 4000 mod
clean 3c if flags last bit is 0, then the file system is set.
A. True
B. False
