An industry customer purchased several Huawei flash storages for business deployment. Engineers need to configure the HyperSnap feature on the storage. However, during the configuration process, the engineers found that snapshots cannot be created for existing protection groups. This abnormal phenomenon may be caused by the available capacity of the storage pool where the source LUN in the protection group is located being 0.
- A . True
- B . False
When engineers perform storage-side tuning on Huawei flash memory, they will take the cache prefetch strategy into consideration.
Which of the following is not a type of cache prefetching strategy?
- A . Fixed prefetch
- B . Smart Prefetch
- C . No prefetching
- D . Elastic prefetching
Huawei distributed storage can provide DPC file services to support the needs of high-performance EPC scenarios. Which of the following descriptions about DPC is wrong?
- A . A single client can connect to multiple storage nodes, and the single-stream bandwidth is higher
- B . DPC can achieve I/O-level load balancing, which can avoid forwarding business loads between storage nodes.
- C . DPC stands for Distributed Parallel Client, which can provide higher storage performance for HPC high-performance scenarios.
- D . DPC does not support PI=I/O, so it can provide better access performance for upper-layer services.
A government customer purchased several Huawei flash storages for carrying upper-layer business data. After the storage system is deployed, the administrator wants to query the relevant setting information of the NTP time synchronization function through the CLI. What command should be configured to achieve this?
- A . Change ntp Server config
- B . show license Active
- C . show ntp source general
- D . show system ntp
A scientific research industry purchased several Huawei OceanStorPacific series distributed storages for business deployment, and engineers configured DPC file services on the storage.
Because the front-end business operation requires higher performance, engineers want to set the CPU of the DPC node to performance mode through the CLI command line. Please analyze which of the following commands has this function?
- A . change service ndmp_restart_service
- B . change pms converged_qos_policy
- C . cpupower frequency-info
- D . cpupower frequency-set -g performance
When performing performance tuning on Huawei flash storage, you need to back up the business system first, and only two configurations can be changed at a time during the tuning configuration.
- A . True
- B . False
When Engineer A was locating a performance problem on Huawei’s flash storage, he found that the latency observed on the computing side was much larger than that on the storage side. This indicates that the problem is likely to be with the storage, for example, the disk performance limit has been reached.
- A . True
- B . False
Erasurecode redundancy technology supports higher reliability and more flexible redundancy strategies than traditional RAID algorithms. Which of the following descriptions of the Erasurecode principle is wrong?
- A . When data is written, it is cut into N data blocks of the same size.
- B . Every N consecutive data blocks calculate M check blocks through the ErasureCode algorithm
- C . The system stores N+M data blocks in parallel on different nodes
- D . In Erasure Code storage mode, the system supports a maximum of M-1 hard disks
Huawei’s distributed storage multi-tenancy feature can provide unified resource management based on tenant granularity, managing and allocating resources on a tenant basis. Which of the following descriptions of this feature are wrong? (Multiple choice)
- A . Account administrators assign different namespaces to different accounts to achieve account namespace isolation, and each account has an independent NAS protocol instance.
- B . The account can be configured with domain control, and each account can be configured with multiple domain environments, including AD domain, NIS domain, etc.
- C . The admin account manages multiple accounts, and each account can create multiple namespaces
- D . The account can configure namespace quota and file quota, but cannot configure Dtree quota
If silent data corruption occurs during data transmission, the possible cause is hardware errors such as memory, CPU, hard disk, etc. Software bugs (such as application bugs) generally do not cause this problem.
- A . True
- B . False
