The various businesses of the enterprise have different storage requirements and need to be finely divided. The customer hopes that different businesses can compete for physical space and achieve optimal configuration of space. Which of the following features can meet the requirements?
정답: B
Due to the increasing number of cloud users, a security enterprise needs to expand a new data center to respond to storage needs, and plans to purchase flash memory storage devices to support image data storage. The site plans to support 300 video signals, each with a flow rate of 1.5Mbps, and requires that each video signal be reserved for at least one month.
known:
1) The nominal capacity of a single hard disk is 931GB, and two coffer disks are configured, each with a size of 480GB, and the coffer disk is not a member disk of a RAID group;
2) The server uses Windows operating system, and the file system uses NTFS, the space occupancy rate is about 0.01%
3) Due to the influence of large data write traffic and large storage space, the basic cost and data security are considered, the RAID strategy will adopt RAID5, the plan is to configure 80+1P, and use the default hot standby strategy (equivalent to creating one hot spare for each RAID group).
What is the approximate total capacity required for this site?

Enterprises use Huawei Data Protection All-in-Ones to protect the operating system and volumes in the production environment using a continuous backup solution. Continuous backup can perform full-machine backup and recovery of operating system volumes and data volumes.
정답: A
A bank deploys two sets of Huawei all-flash storage. Storage A is deployed in the production center, and storage B is deployed in the disaster recovery center. The planning information is as follows:
(1) The business data, logs and modification information of the transaction system database are stored in LUNO1, LUNO2 and LUNO3 of storage A respectively;
(2) When storage A and storage B establish a remote replication relationship, add the remote replication pair of LUNO1, LUNO2, and LUNO3 to the consistency group.
During the process OF data synchronization, the remote replication task of LUNO2 fails.
The consistency group will immediately stop the remote replication tasks for LUNO1 and LUNO3.
