Huawei H19-308_V4.0 Exam Syllabus Topics:

TopicDetails
Topic 1
  • 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.
Topic 2
  • 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.
Topic 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.
Topic 4
  • 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.
Topic 5
  • OceanStor Pacific: OceanStor Pacific is Huawei's distributed storage for massive-scale data management and cloud-native applications. It provides scalability, resilience, and performance for big data, AI workloads, and large-scale storage.
Topic 6
  • NAS Storage Basis: Network-Attached Storage delivers file-level storage over standard networks, accessible to multiple users simultaneously. NAS systems offer cost-effective solutions for file sharing, collaboration, and centralized data management.

Huawei HCSA-Presales-Storage V4.0 Sample Questions (Q18-Q23):

NEW QUESTION # 18
In SmartMulti-Tenant, a vStore is managed by only one tenant administrator, and vStores are isolated from each other.

Answer: B


NEW QUESTION # 19
OceanProtect backup storage supports backup-storage-based deduplicated replication to transmit non-duplicate data, greatly saving the replication network bandwidth.

Answer: B

Explanation:
OceanProtect backup storage supports backup-storage-based deduplicated replication, which transmits only non-duplicate data. This process significantly reduces the amount of data transferred over the network, thus saving replication network bandwidth and improving replication efficiency.


NEW QUESTION # 20
Which of the following are differences between scale-out storage and array storage? (Select all that apply)

Answer: B,C,D

Explanation:
Huawei distinguishes Scale-out Storage (OceanStor Pacific) from traditional Array Storage (Centralized SAN/NAS) based on its ability to handle the "Yottabyte Era" requirements of mass data.
Large Volume (Option A): While traditional arrays are limited by the number of controllers and disk enclosures they can address, scale-out storage is designed to aggregate thousands of nodes into a single global namespace, easily managing 10 PB or even EB-level data volumes.
TB-level Bandwidth (Option C): Distributed storage excels at throughput. By utilizing a high-speed interconnected network (InfiniBand or RoCE) and parallel access protocols like DPC, a scale-out cluster can deliver aggregate bandwidth in the range of TB/s, which is critical for HPC and big data analytics.
Elastic Scalability (Option D): Traditional arrays typically scale out to a few dozen controllers. OceanStor Pacific can scale out to 4,096 nodes in a single cluster, providing linear growth in both performance and capacity as nodes are added.
Performance in IOPS (Option B) is not a difference in the sense that both systems provide IOPS; however, centralized all-flash arrays (Dorado) are often superior for low-latency, high-IOPS structured databases, whereas scale-out storage is primarily defined by its massive bandwidth and capacity scalability.


NEW QUESTION # 21
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 # 22
Which of the following are the main differences between enterprise WORM and compliance WORM? (Choose all that apply.)

Answer: A,B

Explanation:
Enterprise WORM supports privileged deletion, allowing authorized users to delete data before the retention period ends if necessary.
Compliance WORM complies with SEC Rule 17a-4, meaning it meets strict regulatory requirements for data retention and immutability, and does not allow privileged deletion.
