Huawei H19-308_V4.0 認定試験の出題範囲：

トピック	出題範囲
トピック 1	OceanStor New Hybrid Flash Storage: OceanStor Hybrid Flash combines flash and disk storage to balance performance and cost-effectiveness. This architecture optimizes resources by placing performance-sensitive data on flash and capacity-oriented data on disk.
トピック 2	Backup and Disaster Recovery: Backup and disaster recovery strategies protect organizations from data loss through redundant copies of critical information. Comprehensive backup solutions ensure business continuity and enable rapid recovery to minimize downtime.
トピック 3	SAN Storage Basis: Storage Area Networks provide high-speed, block-level storage over dedicated networks for enterprise applications requiring low latency. SAN enables multiple servers to share storage resources while supporting advanced features like snapshots and replication.
トピック 4	Object Storage Basis: Object storage manages data as discrete units with metadata and unique identifiers for efficient retrieval. This scalable architecture suits unstructured data, cloud applications, and big data analytics requiring massive capacity.

Huawei HCSA-Presales-Storage V4.0 認定 H19-308_V4.0 試験問題 (Q65-Q70):

質問 # 65
2200 V3/2600 V3 supports SSD, SAS and NL-SAS disk drives,

A. TRUE
B. FALSE

正解：A

質問 # 66
Thin provisioning allocates storage space on demand, improving resource utilization.

A. TRUE
B. FALSE

正解：A

解説：
Huawei's SmartThin technology is a thin provisioning feature that allows storage administrators to allocate more logical capacity to servers than is physically available in the storage pool. Traditionally, "thick provisioning" reserves the entire capacity of a LUN the moment it is created, leading to significant "stranded" or wasted space if the application does not immediately use it.
With SmartThin, the storage system only consumes physical blocks when data is actually written to the disk. This "on-demand" allocation ensures that physical resources are shared across multiple LUNs more efficiently. For example, a 10 TB LUN might be presented to a database, but if the database only contains 2 TB of data, only 2 TB of physical space is consumed. This significantly improves the Storage Resource Utilization Rate and reduces the Total Cost of Ownership (TCO) by delaying the need to purchase additional physical disks until the actual consumed capacity approaches the physical limits of the array.

質問 # 67
What are the major differences between distributed storage and centralized storage?

A. Distributed storage features high elasticity and scalability accelerating service rollout.
B. Distributed storage uses general-purpose servers as storage hardware for unified management
C. The distributed architecture facilitates capacity expansion and reduction and eliminates data migration.
D. Distributed storage is applicable to cloud storage resource pools. content repository, archiving.
and big data storage.

正解：A、C、D

質問 # 68
Which of the following is NOT a capability of Huawei OceanStor Pacific scale-out storage that ensures always-on services?

A. SAN and NAS integrated active-active
B. Fast failover within 10s upon a node fault
C. Cross-site EC multi-active (HyperGeoEC)
D. Multi-replica cross-site and multi-active (HyperGeoMetro)

正解：A

解説：
Huawei OceanStor Pacific is a distributed scale-out storage system optimized for mass unstructured data (File, Object, HDFS). While it provides robust "always-on" service capabilities, Option A is incorrect as it refers to a specific feature of centralized unified storage arrays like the OceanStor Dorado series. OceanStor Dorado is marketed as providing the industry's only "Active-active solution for SAN and NAS" within a centralized architecture.
In contrast, OceanStor Pacific ensures service continuity through distributed mechanisms:
Fast Failover (Option B): Technologies such as multi-module concurrent service takeover enable services on a faulty node to be taken over within 10 seconds, minimizing RTO.
HyperGeoMetro (Option C): This feature provides multi-replica cross-site active-active protection for object storage, allowing data to be accessed and modified at multiple sites simultaneously.
HyperGeoEC (Option D): This is a cross-site Erasure Coding (EC) multi-active solution that provides high reliability and space utilization for large-scale deployments.
Because OceanStor Pacific is designed for distributed unstructured workloads rather than integrated SAN/NAS block-and-file convergence in the traditional sense, Option A is the outlier.

質問 # 69
A storage pool is a logical combination of multiple storage tiers. A storage tier is a collection of storage media with the same performance in a storage pool.

A. True
B. False

正解：A
