QUESTION 56
Create a Thin LUN on Huawei OceanStor V3 with a capacity of 100G and an initial allocated capacity of 10G. After the LUN is mapped to the Windows 2012 host, the corresponding disk is scanned on the host. The displayed capacity of the disk should be 10G.

QUESTION 57
When writing 500 bytes of data for RAID 3, if the sector size of the mechanical hard disk in the RAID group is 512 bytes, because the amount of written data is small, data verification is not required.

QUESTION 58
Which of the following two descriptions is correct?
Description 1: Synchronous remote replication. When the primary storage fails, the amount of data loss can be zero.
Description 2: When the host is a Linux-based file system, asynchronous remote replication must be used.

QUESTION 59
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.
