Huawei OceanStor flash storage supports two directory creation and distribution modes, namely balanced mode and performance mode. The performance mode is suitable for scenarios such as data backup and archiving, video surveillance, and has the highest file read and write performance.
- A . True
- B . False
A company uses Huawei’s distributed storage block service to run data services. The development team needs to use business data for data mining and testing without affecting the business data.
Which of the following descriptions are correct? (Multiple choice)
- A . The source data and cloned data each evolve into two different copies of data
- B . Create clones based on volumes/snapshots and read and write to clones
- C . Generate a snapshot of the data to be tested at a certain point in time
- D . Create a clone of the snapshot and use the clone for testing
A financial customer purchased multiple Huawei OceanStor Dorado18800 storage devices to carry business data. However, during the actual operation, it was found that the storage environment had FC link abnormalities. Please analyze which of the following reasons may be the cause? (Multiple choice)
- A . When the switch is networked, the configured rate of the FC host port does not match the switch rate.
- B . The optical fiber connection is loose or the optical fiber is damaged
- C . The IP address of the application server service network port is wrongly configured
- D . The host port optical module rate does not match
In Huawei’s container storage solution, CSI stands for ContainerStorageInterface, which means container storage interface.
Which of the following descriptions about Huawei CSI is wrong?
- A . CSI Node runs in each working node of Kubernetes as a Pod in Daemonset mode, and can be used to mount and unmount related storage resources.
- B . CSl Controller mainly runs as a Pod in Statefulset mode in a single working node, which is used to interact with storage and create and delete storage resources.
- C . Huawei storage and Huawei CSI driver need to use RESTful to communicate to provide NAS/SAN storage resources
- D . The CSI Driver developed by Huawei is mainly used to implement the calls initiated by the sidecar on Huawei storage
Based on RAID2.0+ technology, during data reconstruction within the same RAID group, which of the following is the corresponding relationship between the normal data blocks used for reconstruction and the faulty data blocks?
- A . Many to One
- B . One-to-one
- C . One-to-many
- D . Many-to-many
An industry customer has purchased a Huawei OceanStor Pacific scale-out storage system for service deployment. An engineer configures NFS file sharing on the storage system through NFSv4.0.
Which of the following commands can the engineer use to switch the user view to the developer view on the command line interface (CLI)?
- A . change domain ad_manager operation=develop
- B . change dns general address=develop
- C . change user_mode current_mode user_mode=developer
- D . change nas_Idap advanced_config
When delivering Huawei all-flash projects, Huawei engineers introduced the HyperCDP feature of flash storage to customers.
Which of the following statements are true about this feature?
- A . Copies created using HyperCDP can be used for data analysis and application testing.
- B . When an application server sends a request to write data to the source LUN after a HyperCDP snapshot is created, the storage system uses the copy-on-write (COW) technology to save the new data to a new location in the storage pool and directs the source LUN’s pointer to the new location.
- C . HyperCDP snapshots cannot be directly mapped to hosts. To read data from a HyperCDP snapshot due to actual service requirements, the administrator needs to share the file system with the host so that the host can read the source file system data at the point in time when the HyperCDP snapshot was created.
- D . HyperCDP is a high-density snapshot and requires the system to construct file system objects.
Therefore, the system memory usage is high.
In the existing network environment, Huawei’s backup appliance can provide strong data protection capabilities.
Which of the following descriptions of the functional architecture of the all-in-one machine is correct?
- A . File system management and protocol access are mainly implemented by the data protection layer
- B . The backup appliance can complete application data protection operations without the need for backup agents during data protection.
- C . DataEnable Engine is a data enabling module that can provide global retrieval and data desensitization related capabilities
- D . Protect Manager is a data flow module, mainly responsible for data processing such as backup, recovery, replication, archiving, and replica mounting.
In the existing network scenario, engineers can use the DeviceManager tool or DME IQ to initialize and configure the Huawei flash storage system, but cannot use SmartKit to perform deployment delivery.
- A . True
- B . False
The engineer checked the latency of the host and array respectively and found that the latency on the host side and the latency on the storage side were both large and the difference was small, indicating that the problem may be in the network.
- A . True
- B . False
