A. RPO does not require 0 for the scenario, it is recommended to use asynchronous remote replication.
B. The main storage using smart cache acceleration, speed up the main storage IO processing speed.
C. According to the service pressure of the LUNs stored on the primary side, assign the home controllers of each LUN to the A and B controllers.
D. If you are using an asynchronous remote replication scheme, you need to design a startup synchronization time based on the RPO metrics and consider the

Question 32

A. Pvmove command does not support Linux cluster.
B. Redhat Linux enterprise 6 version of lvm does not support the pvmove command.
C. You need to install the cmirror package and run it on the cluster server.

Question 34
A N8500 (V200R001) clustered NAS system with a set of storage units at the back end. Three RAID Groups, respectively named RG1, RG2, RG3 have been created on the storage unit. There are two LUNs under each RAID group, the capacity of each LUN is 12G.The names are RG1-LUN1, RG1-LUN2, RG2-LUN1, RG2-LUN2, RG3-LUN1, RG3-LUN2, and all LUNs are added to one in storage pool. The purpose is to create a file system based on these LUNs. What of the following will certainly create a failure?
A. fs create striped fs01 10g 3 RG1-LUN1, RG2-LUN1, RG3-LUN1 stripeunit = 2048 blksize = 8192
B. fs create mirrored fs02 10g 2 RG1-LUN2, RG2-LUN2 stripeunit = 2048 blksize = 8192
C. fs create mirrored-stripe fs03 10g 2 2 RG1-LUn1, RG2-LUN1 protection = disk stripeunit = 2048 blksize = 8192
D. fs create striped-miiro fs04 20g 2 3 RG1-LUn1, RG1-LUN2, RG2-LUN1, RG2-LUN2, RG3-LUN1, RG3-LUN2 protection = disk stripeunit = 512 blksize = 1024

Question 35

A. Check if the size of the migrated file is the same as the original data.
B. Check if the number of documents corresponds to the original data
C. Check if each file with read and write permissions corresponds to the original data
D. Whether the time for reviewing the case file corresponds to the original data.

Question 36

A. vg01
B. vg02
C. vg01 vg02
D. empty
