Which of the following descriptions of NAS solutions are correct? (Multiple choice)
- A. IP network interconnection is adopted between NAS client and NAS storage device
- B. NAS provides storage resources through file-level data access and sharing
- C. Sharing can be provided externally through the FC network
- D. Mainly use CIFS and NFS protocols
Answer: A,B,D
NEW QUESTION 279
Which of the following description about CIFS and NFS sharing is incorrect? (Multiple choice)
* If the file system has been set as a CIFS share and then an NFS share is added, the NFS share can only be set as read-only.
* If the file system has been set as an NFS share and then a CIFS share is added, the CIFS share can only be set as read-only.
* CIFS is a network-based sharing protocol, which requires high reliability of network transmission, so it usually uses TCP/IP. NFS is used for independent transmission, so it uses TCP or UDP.
* One disadvantage of NFS is that the client must be equipped with dedicated software. CIFS is integrated into the operating system and no additional software is required.
* NES is a stateless protocol. And CifS is a stateful protocol. After NFS connection fails, the connection can be automatically restored, but CIFS cannot. CIFS only sends a little redundant information, so it has a higher transmission efficiency than NFS.
- A. CIFS is a protocol based on network sharing, which has high requirements on the reliability of network transmission, so TCP protocol is usually used for transmission
- B. Regardless of CIFS or NFS protocol, the client is required to perform file format conversion.
- C. One disadvantage of CIFS is that Windows clients must install professional software
- D. NFS is a stateless protocol, while CIFS is a stateful protocol. NFS can automatically recover from link failures, while CIFS cannot
Answer: B,C
NEW QUESTION 280

- B. Rotational speed will affect iops under continuous io conditions
- C. Seek is the main factor affecting the random performance of hard disk random IO
- D. The capacity of a single disk will directly affect the performance of the hard disk
Answer: A,D
NEW QUESTION 284
Description 1: The data recovery of the snapshot depends on the source data.
If the source data is physically damaged, it cannot be recovered.
In this case, the clone can still recover the source data.
Description 2: After the source data is damaged, LUN copy must make a complete copy of the backup data to restore the source data.
The clone only needs to restore the damaged data, which greatly shortens the recovery time.
-Snapshot: The data recovery of a snapshot depends on the source data. If the source data is physically damaged, it cannot be recovered. In this case, the clone can still recover the source data.
-LUN copy: After the source data is damaged, LUN copy must make a complete copy of the backup data to restore the source data. The clone only needs to restore the damaged data (incremental copy), which greatly reduces the recovery time.
-Remote replication: Remote replication can only protect data between storage devices. The hardware cost is high, and the remote link bandwidth is usually low, and the data recovery time is long. The cloning can realize data protection in the storage device, which can effectively save expenses and shorten the data recovery time.
- A. Description 1 is wrong, description 2 is wrong
- B. Description 1 is wrong, description 2 is correct
- C. Description 1 is correct, description 2 is correct
- D. Description 1 is correct, description 2 is wrong
