Exam H19-308_V4.0 Topic 2 Question 65 Discussion

Actual exam question for Huawei's H19-308_V4.0 exam
Question #: 65
Topic #: 2
Files in the WORM (Write Once, Read Many) state can be read but cannot be modified.

Suggested Answer: A Vote an answer

Huawei's HyperLock feature provides WORM (Write Once, Read Many) functionality for NAS file systems. When a file is placed in the WORM state, the storage system strictly enforces a policy where the file's data can be accessed and read by authorized users, but any attempt to modify, overwrite, or delete the file is blocked by the storage controller.
In the Huawei OceanStor system, a file enters the WORM state after it is "locked." Once locked, the file remains in a read-only state for a defined retention period. During this time, not even an administrator can modify the file's content or reduce its protection duration. This is critical for meeting regulatory compliance (such as SEC Rule 17a-4) and for protecting sensitive data against ransomware, as it ensures that once data is archived, it remains immutable and verifiable. Only after the retention period has expired can the file be deleted, though it can still never be modified.
