A.It is very convenient for users to share through the CZFS protocol to read, write, author and operate files stored in the storage system just like using this machine.

B.Also known as SMB (server message Block) has been released in multiple versions, such as SMB 1.0, SMB 2.0, SMB 3.0, so it needs version matching when using

C.The supported authentication methods are NILMKberos

D.CIFS adopts the B/S architecture model, so the administrator needs to confirm the browsing version when performing attachments.

A.Can detect business volume in real time

B.Snapshot recovery technology can be used to detect the business volume of the last month

C.You can use snapshot recovery data to recover data lost by physical problems

D.Can use snapshot technology to test and develop software

A.True

B.False

A.The data is automatically and evenly distributed on the hard disks in the storage pool, avoiding unevenness of the hard disks, thereby reducing the overall failure rate of the storage system

B.The data on a single LUN is distributed to many different hard disks, avoiding hard disk hot spots and greatly improving the performance and capacity of a single LUN.

C.There is no write penalty in RAID 2.0+, which overcomes the impact of write penalty in RAID 5 and RAID 6 levels in traditional RAID technology on LUN write performance, and greatly improves LUN performance

D.Overcoming the performance bottleneck of the target disk (hot spare disk) of traditional RAID reconstruction, so that the write bandwidth of the reconstructed data stream no longer becomes the bottleneck of the reconstruction speed, which greatly improves the reconstruction speed and reduces the failure of double disks. Probability, which improves the reliability of the storage system.

A.In the NFS working process, the request of the client program can be directly sent to the server without RPC.

B.RPC service can uniformly manage NFS port commands

C.RPC can provide services for sharing data during NFS work.

D.The NFS service must be started on the RPC service, otherwise NFS will not be able to register port information with RPC
