The HyperClone feature in Huawei OceanStor Dorado systems creates full data copies for reliability and testing. The *HCIP-Storage V5.5 Training Material (Module 2: Flash Storage Technologies)* states: “HyperClone creates a full copy of a source LUN to a target LUN. A source LUN can form multiple HyperClone pairs with different target LUNs. Data copying starts at synchronization, but hosts must wait for the copy to complete before accessing the target LUN. HyperClone supports bidirectional synchronization, allowing data restoration from target to source. For block storage, it uses redirect-on-write (ROW), while file system clones use copy-on-write (COW).” Let’s evaluate:

- Option A: False. The material confirms that a source LUN can form multiple HyperClone pairs with different target LUNs.

- Option B: False. Hosts cannot access the target LUN until the copy process completes, contrary to the statement.

- Option C: True. Bidirectional synchronization is supported, including restoration from target to source.

- Option D: True. The material distinguishes ROW for block clones and COW for file system clones.

Thus, options A and B are false.
