HCIP-Storage V5.5 - H13-624_V5.5 Exam Practice Test

Question 1

Assume a government office purchases a Huawei OceanStor Pacific 9550 storage device. During an inspection, an engineer notices the LAN on motherboard (LOM) optical port indicator on the rear panel of the device is steady yellow. This indicates that data is being transmitted at a rate of
25 Gbit/s.

Question 2

In direct TCP offload engine (DTOE) 2.0, all TCP connections share the same hardware sending queue, and data in the receive direction of read requests does not need to be copied. This reduces CPU consumption and latency.

A. TRUE

B. FALSE

Question 3

Assume a financial customer purchased several Huawei scale-out storage devices for deploying the video surveillance service. This service has high requirements on performance. Therefore, the cache write policy must be set to write-through for the storage devices.

A. TRUE

B. FALSE

Question 4

A financial customer has purchased several Huawei OceanStor Dorado series storage devices for service deployment. To ensure service data reliability, an engineer configures the HyperSnap feature. Which of the following statements is false about the engineer's configuration?

A. After a snapshot LUN is created, the engineer can map it to a host.

B. Before creating a snapshot, the engineer needs to import and activate a related license on DeviceManager.

C. When creating a snapshot, if the capacity of a source LUN is 10 GB, the engineer can only select a target LUN whose capacity is also 10 GB.

D. Before creating a protection group on DeviceManager, the engineer needs to create a snapshot consistency group.

Question 5

An engineer can use multiple common management software to configure, manage, and maintain Huawei converged storage. Which of the following statements is false about the software and corresponding functions?

A. DME IQ enables cloud-based management, remote maintenance, automatic service request creation, and prediction and prevention, comprehensively improving customers' O&M capabilities.

B. The command-line interface (CLI) allows the engineer to allocate storage resources, manage users, manage data protection features, monitor device performance, and manage alarms.

C. DeviceManager allows the engineer to allocate storage resources, manage users, manage data protection features, monitor device performance, and manage alarms.

D. SmartKit provides capabilities such as alarm reporting, file upload, and remote access.

Question 6

Huawei OceanProtect Appliance adopts the key technology of CPU core grouping and intelligent scheduling, which is widely used by customers in many industries. Which of the following is the advantage of this technology?

A. This technology implements physical and logical isolation of resources, reducing latency.

B. The system can prefetch data and metadata from all LUNs, improving the cache hit ratio.

C. The scheduler can distribute jobs to other cores based on the service load status, implementing load balancing.

D. When this technology is used to carry different services, some cores are overloaded, resulting in high latency.

Question 7

RAID 2.0+ differs greatly from traditional RAID technologies. Which of the following statements are true about the RAID 2.0+ technology? (Choose all that apply.)

A. During LUN creation, grains are mapped to LUNs for refined management of storage resources.

B. The storage system divides each disk in a storage pool into chunks of a fixed size. The size of a chunk is usually 8 MB.

C. Generally, a chunk group is divided into 32 KB grains.

D. Chunks from different disks form chunk groups based on the user-defined RAID policy.

Question 8

A LUN has been created successfully, but the host cannot detect it. Which configuration is MOST likely missing?

A. Storage pool creation

B. Mapping View configuration

C. Snapshot creation

D. RAID group configuration

Question 9

When the OceanStor Pacific series system is overloaded, inline deduplication automatically stops and switches to post-process deduplication. At this moment, data is flushed to disks for persistent storage. When sufficient system resources are available, the system starts post-process deduplication.

A. TRUE

B. FALSE

Question 10

A storage system encounters CPU performance issues, such as slow response during system access, decreased QPS and TPS, and prolonged response time. Which of the following methods can be used to optimize performance? (Choose all that apply.)

A. Replace the current CPU with a more advanced CPU.

B. Add system modules, such as front-end processors and parallel servers.

C. Reduce the data block buffer size.

D. If there are multiple CPUs, allocate load among CPUs properly.
