A financial customer purchased several Huawei OceanStorPacific storages for business deployment. Engineers configured object storage services on the storage system. It is known that there is an AD domain controller in the existing network. Engineers need to add the storage system to the AD domain controller environment. Please analyze which of the following is not a prerequisite that needs to be met before adding the AD domain controller?
- A . IDAP domain environment needs to be built
- B . Before joining, all storage nodes and the DNS server network are connected
- C . The AD domain server and DNS server need to be synchronized with the storage system time
- D . TCP ports 88, 389, 445, 464, and 636 need to be opened between the storage system and the AD domain environment.
During flash storage initialization, an administrator needs to change the IP address of a management network port.
Which statements about the change are false?
- A . To change the IP address of the management network port on the CLI, log in to the CLI and run the "change system management_ip" command.
- B . The IP addresses of the management and maintenance network ports must be in different network segments; otherwise, there will be a route conflict.
- C . The administrator needs to apply for and activate a license before changing the IP address of the management network port.
- D . To change the IP address of the management network port on the command-line interface (CLI), the IP address of the maintenance terminal and the default IP address of the storage management network port must be in the same network segment if the administrator logs in to the system through a serial port.
Which of the following stages does the storage system not go through when using the SmartTier feature to classify different storage resources?

Compared with traditional RAID technology, RAID2.0+ has significant differences.
Which of the following descriptions about RAID2.0+ technology are correct? (Multiple choice)
- A . The storage system divides each hard disk in the storage pool into fixed-size chunks, which are usually 8MB in size.
- B . Usually, Chunk Group is further divided into 32KB Grains.
- C . Chunks from different hard disks will form a Chunk Group according to the RAID policy set by the user.
- D . When users create LUNs, the storage system maps grains to LUNs, thereby achieving refined management of storage resources.
