NEW QUESTION # 60
In the medical picture archiving and communication system (PACS), X-ray, MRI, CT, and ultrasound tests generate a large number of image files every day. The file size ranges from 100 KB to 1 MB. Which of the following Huawei NAS products are recommended for the system? (Select all that apply)
Answer: B,D
Explanation:
Huawei provides tailored solutions for Medical PACS based on the specific performance and scale requirements of healthcare providers. OceanStor Dorado NAS (Option D) is recommended for the " Hot Data
" or active tier of a PACS system. Because medical images between 100 KB and 1 MB require high- concurrency access and extremely low latency for immediate clinical review, the FlashLink technology and all-flash architecture of the Dorado series provide the necessary IOPS to prevent bottlenecks during peak hours.
OceanStor Pacific (Option C) is the primary recommendation for the massive, long-term unstructured data storage required by PACS. A single hospital can generate petabytes of data over several years. OceanStor Pacific's scale-out architecture allows it to handle billions of small files efficiently using a global namespace, and its high-ratio Erasure Coding (EC) ensures maximum capacity utilization and lower TCO for archives.
While Hybrid Flash (Option A) can be used, it is often superseded by the superior performance of Dorado or the superior scalability of Pacific in modern medical environments. FusionCube (Option B) is an HCI solution more suited for edge computing or virtualization rather than specialized, large-scale medical imaging repositories.
NEW QUESTION # 61
When user A modifies a file in the NAS system, which of the following operations can user B perform on the file?
Answer: B
Explanation:
In Huawei OceanStor NAS systems, data consistency and integrity are maintained through a mechanism known as File Locking. When User A opens a file for modification (a write operation), the storage system applies a "Write Lock" or an "Exclusive Lock" to that specific file. This lock prevents other users from performing any actions that would alter the file's metadata or content, as these concurrent changes would lead to data corruption or "lost updates".
Consequently, File deletion (Option A), File modification (Option C), and File renaming (Option D) are all blocked because they require write-level access or changes to the file system's directory structure that conflict with the active lock held by User A. However, File reading (Option B) is generally permitted unless User A has specifically requested an exclusive lock that bars all access. In standard CIFS/SMB and NFS configurations used by Huawei, multiple users can read a file while one user is writing, ensuring that information remains accessible without compromising the integrity of the file being updated.
