Customer business is very important and has a large amount of data, requiring the best possible business continuity after natural disasters. Which kind of network design is best for this?
- In the same city set up two data centers to do synchronous replication, located in another remote data center to do asynchronous remote replication
- Set up two data centers in the same city to form a dual disaster recovery network
- Set up a data center in the local and remote sites to form a dual-active disaster recovery network
- In the same city set up two data centers to do double live in another remote data center to do asynchronous remote replication
-
When installing Simpana, the client agent is installed on the server. There are two configured IP cards that the administrator how to set up, how should this be done?
- Add data interface pair
- configure the firewall
- Add host resolution
- Configure the host route
-
Hot-plugging refers to replacing, adding, upgrading, and removing hardware devices without shutting down the system or power supply. Hot plugging of PCIE is a kind of “no surprise” strategy, that is, when the user unplugs the interface card, you must first notify the system.

A company IT system administrator is responsible for the configuration management of OceanStor V3 storage system in Huawei. In the scenario described, which of the following is the correct configuration of Smart Migration:
- Configure LUN A and LUN B on Huawei OceanStor V3, create a snapshot for LUN A, and then use LUN A as the source LUN and LUN B as the Target LUN
- Configure the controllers that belong to LUN A and LUN B to be different on OceanStor V3, with LUN A as the source LUN and LUN B as the target LUN
- Huawei OceanStor V3 configures LUN A and LUN B, maps LUN B to a host, and then uses LUN A as the source LUN and LUN B as the target LUN
- On Huawei OceanStor V3, configure that thick LUN A and thin LUN B belong to the same controller, and LUN A is the source LUN LUN B is the target LUN
-
With OceanStor V3 storage, which of the following businesses use smartTier features to improve storage system performance and reduce user costs? (Multiple choice)
- Data Warehouse
- online shopping
- Data Mining
- ERP
-
When a Simpana backup client failed to perform the backup task, the status reported the following error “failed to connect to indexing process from client [client] to [MediaAgent * MediaAgent * 8400 * 8402] .Error [Inability to connect to remote machine[MediaAgent] .Please check Network Connectivity or the machine may be down].” You check the client and the media service devices are normal. The possible reasons for this problem are:
- The client JobResults directory is full
- The media server IndexCache directory is full
- The media server can not resolve the client host name
- The client can not resolve the media server host name
-
Some OceanStor V3 storage resources are mapped to a host as raw devices. The host then creates dedicated file systems on these raw devices. A test tool is used to create a large number of 13 KB files in the file systems. The test tool is also used to read those files randomly for testing the response. In this circumstance, changing the prefetch policy of the tested LUN to constant prefetch and setting the prefetch length to 16 KB can increase the system performance.
- True
- False
-
In a clustered environment, data is placed on the shared storage, and identities between peers are equal and have the same access to the data. It is required that the clusterware have a control mechanism for concurrent access to such peer permissions. In Oracle RAC, you use the _____ mechanism to do multiple node-to-node collisions control of access.
- vip
- ocr
- dlm
- asm
-
True of False, N8500 volume mirroring function synchronization can be understood as a file system to do RAID 1 to achieve image protection This protection is done in two ways:
One Species is the mirror roll between showrooms, the display level of protection, a display failure, the business is not affected; the other is the mirror image display within the exhibition.
RAID level protection, a RAID group failure, the business will not be affected.
- True
- False
-

- LUN copies and clones have the data of the original volume at the moment when the original data is initiated (or started) for the backup of the original data
- LUN copies and clones need to stop the host business during execution
- LUN copies and clones can both be executed in the same display
- Both LUN copies and clones can be incrementally synchronized
-
Which of the following is correct regarding FTP passive transmission mode:
