If a company's business is to write large-scale data randomly into LUNs, which initial capacity allocation strategy and which data migration strategy are recommended?

There are two statements about backups as follows:
Statement 1: The data backed up on the tape can be used for data recovery at any time, but only the historical data at the time of the backup can be recovered, not the data at the time of the failure.
Statement 2: Using tape as the backup medium is the highest RTO backup method.

Data management is the process of using computer hardware and software technology to effectively collect, store, process and apply data. In chronological order, what phases can data management be divided into? (Multiple Choice)

In the Huawei OceanStor V3 storage system, which of the following statement of Smart Thin LUN is correct?

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.
