Huawei HCSA-Presales-Storage V4.0 Sample Questions (Q72-Q77):

NEW QUESTION # 72
Which model supports expansion of up to 32 controllers?

Answer: D


NEW QUESTION # 73
Which features can improve system performance in SAN storage? (Select all that apply)

Answer: B,C

Explanation:
In Huawei OceanStor Hybrid Flash systems, performance optimization is achieved through intelligent resource management. Level-2 cache (Option A), known as SmartCache, utilizes SSDs as an extension of the system's DRAM cache. By storing "hot" data on high-speed SSDs, the system significantly reduces the read latency for frequently accessed blocks that have been evicted from the primary memory cache.
Storage tiering (Option D), or SmartTier, automatically migrates data blocks between different storage tiers (SSD, SAS, and NL-SAS) based on their access frequency. It ensures that active data resides on the highest-performance media while moving inactive "cold" data to high-capacity drives. These two features are specifically designed to maximize IOPS and minimize response times. In contrast, Thin Provisioning (SmartThin) and Data Deduplication (SmartDedupe) are "Storage Efficiency" features; their primary goal is to save physical space and improve capacity utilization. While essential for TCO, they do not inherently improve raw system performance and may involve a minor metadata overhead during processing.


NEW QUESTION # 74
Which of the following new concepts is proposed by Huawei for data backup solutions?

Answer: A

Explanation:
Huawei proposes the new backup concept D2F2T (Disk-to-Flash-to-Tape), which leverages flash storage to accelerate backup and restore processes, providing a faster and more efficient data protection solution compared to traditional D2D2T (Disk-to-Disk-to-Tape) methods.


NEW QUESTION # 75
Flash-to-flash-to-anything (F2F2X) allows primary storage service data and core service backup data to be stored in flash storage and allows data to be tiered and archived to any media.

Answer: B

Explanation:
The statement is true. Flash-to-flash-to-anything, or F2F2X, describes Huawei's modern data protection approach in which both production data and important backup data can be kept on flash- based storage for high performance, while older or colder data can be tiered or archived to other media. The first "flash" represents high-performance primary storage for business applications. The second "flash" represents fast backup storage, which improves backup and recovery speed compared with traditional disk or tape-only designs. The "anything" part means that data can later be moved to other storage targets such as disk, tape, cloud, or object storage according to cost, retention, and compliance requirements. This model balances fast recovery for critical data with economical long- term retention.


NEW QUESTION # 76
In the medical PACS system, X-ray, MRI, CT, and ultrasound tests generate a large number of image files every day. The file size ranges from 100 KB to 1 MB.
Which Huawei NAS product is recommended?
