Huawei explains that a file-system snapshot is a point-in-time copy. When source data changes, ROW writes the new data to another location while the snapshot continues to reference the original data, thereby preserving the source file system ' s state at snapshot creation time.

The statement is TRUE. Snapshot rollback changes the active file-system data state back to the selected protection point. Active NAS clients must therefore not continue issuing file operations against the source file system while that authoritative state is being replaced. The host share is unmounted before rollback so that active client I/O cannot conflict with restoration of snapshot metadata and data mappings.

The HCIE materials also show the same operational consistency principle in rollback workflows: upper-layer service access is stopped before storage state is reverted. In the Lab Guide ' s rollback procedure, the first action is to stop upper-layer service access and unmount the relevant file system before storage mappings are changed.

This ensures that the post-rollback file system presents one internally consistent point-in-time image when service access resumes.

The HCIE-Storage Lab Guide demonstrates cross-protocol networking on OceanProtect X6000. During logical-port creation, it directs the administrator to “Set Data Protocol to NFS + CIFS.”

The Training Materials likewise explain that OceanProtect supports standard protocols including NFS and CIFS, allowing backup data in native format to remain accessible through standard storage protocols.

For a file system that must be accessed and controlled from both UNIX/NFS and Windows/CIFS environments, the required security style is Native mode. This mode allows the file system to retain and interpret the native permission model appropriate to the protocol through which the file is accessed, enabling mixed NFS/CIFS access without forcing the entire file system into only UNIX-style or only NTFS-style security semantics.

The retrieved Training and Lab Guide passages explicitly establish simultaneous NFS+CIFS operation on OceanProtect; the precise “Native mode” security-style label is not expanded in those retrieved passages, but it is the configuration value associated with the described mixed-protocol requirement.

The supplied HCIE-Storage question set identifies A, B, and C as correct.

Link compression is an inter-array transmission optimization associated with HyperReplication. Because it operates on the replication path rather than in the host/application data path, it is transparent to the application server. The host continues to perform ordinary reads and writes against the primary storage system while HyperReplication handles the remote synchronization process.

Huawei describes HyperReplication as the core technology used to synchronize copies of local data to a remote storage system and distinguishes synchronous and asynchronous replication modes. For asynchronous replication, changed data is collected and transferred to the secondary system according to the replication period. Compression can therefore be applied inline to the transmission stream to reduce required WAN bandwidth.

Option D is not part of the keyed link-compression sequence. The retrieved Training Materials establish the HyperReplication transport and consistency mechanisms, but the parsed course text available here does not provide a detailed link-compression processing sequence that independently substantiates the specific “decompress first, then verify” assertion. Therefore, that additional sequence should not be inferred.

The O & M training material defines the diagnostic information available through DeviceManager. It states that DHA runtime logs are disks ' daily running logs, including disk-health statistics, I/O statistics, and service-life information. It also states that HSSD logs contain S.M.A.R.T. information and disk running logs. The same section states that DeviceManager provides Download Recent Log or All Logs for configuration, event, and debugging information, as well as Download DHA Runtime Log or HSSD Log for disk runtime, I/O, service-life, and S.M.A.R.T. information. In a multi-controller Huawei storage system, diagnostic information is distributed among controllers. The log-download operation therefore performs the collection stage before producing the controller-associated downloadable packages. This design ensures that the final log set reflects information from the relevant controllers rather than only the management controller.

The Training Materials explicitly document the available log categories and DeviceManager collection mechanisms; the controller-by-controller collection progress is part of the operational log-download workflow.
