Huawei H19-308_V4.0 Prüfungsplan:

ThemaEinzelheiten
Thema 1
  • 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.
Thema 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.
Thema 3
  • 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.
Thema 4
  • OceanStor Dorado: OceanStor Dorado is Huawei's all-flash storage solution for mission-critical applications demanding ultra-low latency. This platform leverages NVMe technology and intelligent management to accelerate digital transformation.
Thema 5
  • Data Storage Basis: Data storage is the foundation of IT infrastructure, enabling efficient storage, management, and retrieval of digital information. Understanding storage fundamentals is essential for selecting solutions that meet business performance, capacity, and reliability requirements.
Thema 6
  • OceanProtect Backup Storage: OceanProtect offers comprehensive data protection with efficient backup, recovery, and retention features. This solution ensures security through encryption and deduplication while reducing storage costs.

Huawei HCSA-Presales-Storage V4.0 H19-308_V4.0 Prüfungsfragen mit Lösungen (Q14-Q19):

14. Frage
A customer wants to purchase an object storage system to be used by different departments. These departments are independent of each other and cannot access each other's dat a. Therefore, the data capacity of different departments needs to be limited. Which of the following object storage features will you recommend to the customer? (Select all that apply)

Antwort: A,B

Begründung:
To meet the customer's requirement for departmental isolation and resource control, Huawei recommends the combination of Multi-tenancy (Option C) and Quotas (Option D).12 Multi-tenancy is the foundational feature for iso3lation in Huawei object storage. It allows the physical storage system to be logically partitioned into multip4le "Tenants". Each department can be assigned its own tenant environment with its own set of users, access keys, and buckets. Data is logically isolated, meaning one department cannot see or access the data of another unless explicitly permitted.
Quota management is then used to limit the capacity consumed by each department. In Huawei OceanStor Pacific, quotas can be applied at the Tenant level or the Bucket level. By setting a Tenant Quota, the administrator ensures that a specific department does not exceed its allocated budget of storage space, preventing one department from exhausting the resources of the entire system. While Replication (Option A) and WORM (Option B) are valuable for data protection, they do not address the specific needs of departmental isolation and capacity limiting.


15. Frage
Which of the following is NOT a capability of Huawei OceanStor Pacific scale-out storage that ensures always-on services?

Antwort: D

Begründung:
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.


16. Frage
Which of the following functions is NOT supported by the OceanStor F V5?

Antwort: C


17. Frage
Backup focuses on service continuity, while disaster recovery focuses on data recoverability.

Antwort: A

Begründung:
According to Huawei's technical standards for data protection, this statement is the reverse of the actual definitions. Backup focuses on data recoverability, while Disaster Recovery (DR) focuses on service continuity.
Backup is the process of creating a redundant copy of data to protect against accidental deletion, data corruption, or hardware failure. Its primary goal is to ensure that a copy of the data exists and can be restored (recoverability). Disaster Recovery, however, involves the infrastructure and processes required to resume business operations (services) after a catastrophic event (like a flood or fire). DR utilizes technologies like HyperMetro (active-active) or HyperReplication (remote replication) to ensure that the application remains available or can be restarted quickly at a secondary site, thereby ensuring Service Continuity. Because the statement swaps these two core objectives, the answer is False.


18. Frage
2200 V3 is the only product that supports SmartVitualizartion among entry-level storage products.

Antwort: B
