NEW QUESTION # 88
Thin provisioning allocates storage space on demand, improving resource utilization.
Answer: A
Explanation:
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.

Which is the correct formation order of the following elements in RAID 2.0+?
Answer: B
NEW QUESTION # 90
OceanStor Pacific supports only three types of protocols: file (NFS/CIFS), object (S3), and HDFS?
Answer: B
Explanation:
The statement is False because Huawei OceanStor Pacific is a multi-protocol storage system that supports more than just the three mentioned protocols. While File (NFS/CIFS), Object (S3), and HDFS are the core protocols for mass data access, the system also supports:
DPC (Distributed Parallel Client): A specialized parallel file system interface that supports standard POSIX and MPI-IO, enabling high-performance computing (HPC) clients to connect directly to multiple storage nodes for balanced I/O.
Block Storage: Certain configurations of OceanStor Pacific can provide block storage services, making it a truly unified distributed platform.
S3 Versioning and Advanced Object APIs: It supports native S3 semantics for object versioning and other advanced cloud-native features.
Because it supports high-performance parallel interfaces (POSIX/MPI-IO) via DPC in addition to the standard protocols, it is technically incorrect to say it supports only three types.
NEW QUESTION # 91
Which three technologies are used by the distributed file system of the new-gen OceanStor hybrid flash storage to improve NAS performance?
Answer: A,C,D
Explanation:
The distributed file system of the new-gen OceanStor hybrid flash storage improves NAS performance through intelligent layout, intelligent balancing, and intelligent cache. Intelligent layout optimizes how file data and metadata are distributed across system resources, reducing access bottlenecks and improving parallel processing. Intelligent balancing distributes workloads across controllers and storage resources so that no single component becomes overloaded during high-concurrency NAS access. Intelligent cache accelerates access to frequently used data by keeping hot data closer to compute and controller resources, reducing read latency and improving user response time. Intelligent search is useful for locating or indexing data, but it is not one of the three core technologies used specifically to improve NAS performance in this context. Therefore, the correct answers are intelligent layout, intelligent balancing, and intelligent cache.
NEW QUESTION # 92
Which of the following deduplication and compression type does OceanProtect adopt?
Answer: B
Explanation:
OceanProtect adopts a variable-length inline deduplication and compression method. Inline deduplication and compression are performed in real-time as data is ingested, saving storage space immediately. The variable-length method allows for greater efficiency in deduplication by dynamically adjusting to the actual data patterns, maximizing storage savings.
