Huawei HCSA-Presales-Storage V4.0 Sample Questions (Q93-Q98):

NEW QUESTION # 93
What are the main industry sales scenarios for V5 NAS?

Answer: C,E


NEW QUESTION # 94
Which of the following are differences between scale-out storage and array storage? (Choose all that apply.)

Answer: A,B,C

Explanation:
Scale-out storage focuses on massive capacity, high bandwidth, and elastic expansion. It delivers TB-level throughput, supports 10 PB-level data capacity, and scales to thousands of nodes, which distinguishes it from traditional array storage that emphasizes high IOPS rather than extreme bandwidth and scale.


NEW QUESTION # 95
Which of the following are features of multi-protocol interworking of Huawei OceanStor Pacific? (Select all that apply)

Answer: A,B,D

Explanation:
Huawei's Multi-protocol Lossless Interworking is a standout feature of the OceanStor Pacific series, allowing one copy of data to be shared across different protocols (File, Object, HDFS).
No Semantic or Performance Compromise (Option B): Historically, protocol conversion (e.g., using a gateway) led to performance loss or "semantic loss" where certain file attributes or object tags were dropped. OceanStor Pacific implements native support for multiple protocols at the metadata level, ensuring full semantic compatibility and high-speed access regardless of the protocol used.
Zero Data Copy (Option C): This feature allows one piece of data to be written via one protocol (e.g., ingested via S3) and read via another (e.g., analyzed via HDFS) without moving or copying the data to a separate system. This eliminates "data silos" and greatly improves data processing efficiency.
Gateway-free (Option D): Because the interworking is native to the storage OS, no external protocol gateways are required. This simplifies the management architecture and reduces the hardware footprint.
Option A is incorrect because documentation generally advises against mixing structured (Database) and unstructured data in the same pool for optimal performance, though the system is primarily optimized for unstructured workloads.


NEW QUESTION # 96
Which type of backup copies the minimum amount of data?

Answer: A


NEW QUESTION # 97
What are the characteristics of DAS? (Select all that apply)

Answer: A,C,D

Explanation:
Direct-Attached Storage (DAS) is a traditional storage architecture where storage devices are connected directly to a host server. Huawei documentation defines the following key characteristics:
Direct Connection (Option C): DAS connects to the server via internal or external interfaces such as SATA, SAS, or SCSI, rather than through a storage network.
No Network Devices (Option A): Because it is a 1-to-1 connection, it does not require Fibre Channel switches or Ethernet switches to facilitate the link between the host and the storage. This makes it simple and cost-effective for small-scale deployments.
Block Storage Services (Option B): Like a SAN, DAS provides block-level access. The server's operating system manages the file system (NTFS, EXT4, etc.) directly on the provided blocks.
While a server attached to DAS can share its files over a network (becoming a file server), the DAS itself is not a "File Storage Service" (Option D). In Huawei's hierarchy, file services are the domain of NAS (Network Attached Storage), which provides shared access to files via protocols like CIFS/SMB or NFS.
