NEW QUESTION # 29
Which types of disk storage pools are supported by the new-gen OceanStor hybrid flash storage?
Answer: A,B,C
Explanation:
The new-generation OceanStor hybrid flash storage supports multiple disk storage pool types to meet different performance and capacity requirements. An SSD pool is used when applications require high IOPS and low latency. An HDD pool is used for capacity-oriented workloads where cost per terabyte is more important than flash-level performance. A mixed SSD + NL-SAS HDD pool is also supported for hybrid scenarios, allowing hot data to benefit from flash performance while colder data is stored on high-capacity NL-SAS disks. This aligns with the hybrid flash design goal: balance cost, performance, and capacity through tiered media. By supporting these pool types, OceanStor hybrid flash storage can serve both performance-sensitive and capacity-heavy enterprise workloads. Therefore, all listed options are correct.
NEW QUESTION # 30
A snapshot is a full copy of a LUN in SAN storage.
Answer: B
Explanation:
A snapshot is not a full copy of a LUN; it is a point-in-time image that initially saves only metadata and tracks changes, enabling quick recovery without duplicating all the data.
NEW QUESTION # 31
Source deduplication reduces the amount of data to be transmitted, saves network bandwidth, and transmits non-duplicate data, improving logical backup bandwidth and shortening backup time.
Answer: B
Explanation:
Huawei OceanProtect utilizes source deduplication to optimize the data protection process. In traditional backup scenarios, the entire dataset is sent over the network to the backup target, which can consume significant bandwidth and time. With source deduplication, the storage system or backup agent identifies redundant data blocks at the source-before they are sent over the network.
By comparing new data chunks against a local cache of already-transmitted fingerprints, the system ensures that only unique, non-duplicate data is physically moved across the production-to-backup link. This significantly reduces network bandwidth consumption and effectively increases the logical backup bandwidth, as the system can process larger volumes of data without being limited by physical network throughput. Consequently, the backup window is shortened, allowing organizations to meet tight RPOs even in environments with limited network resources or massive data growth.
NEW QUESTION # 32
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 # 33
What are the major differences between distributed storage and centralized storage?
Answer: A,C,D
NEW QUESTION # 34
