Quota tree is a first-level directory under the file system, which can only be created, deleted, and renamed by the administrator through the command line or GUI management interface. Ordinary users can

To delete the empty Quota tree

Quota tree can be renamed and deleted when shared by agreement

Ordinary users can perform quota management on the number or capacity of files under Quota Tree

12. Comparing NAS storage system and file server, what are the advantages of NAS storage system? (Multiple Choice)

High stability and high reliability

Diversified services and powerful functions

Large storage space

High data security

13. What are the synchronization types of asynchronous remote replication? (Multiple Choice)

Manual

Automatic

Wait regularly after synchronization starts

Wait regularly after synchronization is completed

Internet Data Center

Enterprise Data Center

Cloud Data Center

15. Which of the following options belong to the form of data? (Multiple Choice)

Text

Video

Sound

Image

16. With the advent of the era of big data, storage technology is also undergoing changes. Which of the following is correct about the changes in storage technology? (Multiple Choice)

The file system has evolved from a local system to a cluster file system and a distributed file system

Large-scale expansion capability is a characteristic of mass storage

Traditional NAS faces PB-level data, and complex volume management leads to uneven capacity allocation

Mass storage is characterized by more complex file systems and more complex management

17. Which of the following is correct about the NDMP protocol? (Multiple Choice)

Is an open protocol based on enterprise-level data management

Support file backup based on CIFS or NFS

Does not support backup disk library

Mainly oriented to the field of data backup and recovery

18. Which of the following descriptions are correct about SAN and NAS? (Multiple Choice)

NAS is characterized by putting the server file system in the storage so that the server needs to share data through the network

Now NAS is geared towards unstructured data storage, such as many department employees for office files and centralized storage

SAN is more used in data scenarios to store structured

DAS, NAS, SAN are all external storage, so storage resource sharing can be easily realized

19. In an enterprise IP SAN network, the host resource occupancy rate is always high. After investigation, it is found that the Initiator software in the host occupies a large amount of resources to complete the conversion of iSCSI packets to TCP/IP packets.
