H13-629_V3.0 Exam Dumps - HCIE-Storage V3.0

Huawei explicitly states: “To back up host files, you must install a data protection client on the host and back up the files in LAN-Base mode.” The first part of the statement is therefore correct.

The second part is not. For NAS backup, the course describes protection of OceanStor V6, OceanStor Dorado, OceanStor Pacific, NetApp, and other third-party NAS shares. For applicable NAS systems, NFS or SMB shares are mounted using the NAS protocol for backup and recovery. It does not define installation of an NDMP client on the NAS host plus mandatory LAN-free operation as the standard NAS backup workflow described here.

Huawei further explains that Dorado and new-generation OceanStor hybrid flash systems can use snapshot-difference and block-level transmission technology for high-performance NAS backup, whereas other systems can use NFS/SMB access. This demonstrates that NAS protection is selected according to the source-storage capabilities and does not universally depend on the asserted NDMP-client/LAN-free combination.

Because the second half of the statement is incorrect, the complete statement is FALSE.

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 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.

Huawei defines To be recovered as the state entered after the fault causing an interruption is rectified when manual recovery is required. The state reminds the administrator that manual synchronization is needed to restore the pair. Therefore, D is correct.

A manually split pair enters Split, meaning replication is suspended; the replication relationship itself is not deleted. An ordinary link or LUN failure causes Interrupted, whereas Invalid is used when the properties of the primary or secondary resource change and the configurations become inconsistent. This makes A and C incorrect.

For file systems, Huawei states that HyperReplication(A) replicates at the file-system object layer and synchronizes all file-system contents and changes to the secondary file system. The WORM section separately documents that file expiration is governed by the WORM regulatory clock.

The retrieved course text documents these two mechanisms separately rather than giving one sentence explicitly naming both WORM fields during replication.

The Lab Guide explicitly requires a pre-configuration check of the service environment and multipathing status before online takeover. It then states: “After eDevLUNs are created, map them to service hosts so that the service hosts can use the target storage.”

The Lab Guide further provides an explicit Configure host path switchover step and later instructs the engineer to switch I/O direction from the source storage to the target storage.

Therefore, checking the environment, mapping the eDevLUNs, and switching host paths are integral parts of the online takeover procedure. Adding route information is optional because it is needed only when the actual network topology requires additional routing to establish management or service connectivity. A directly reachable storage network does not require an additional route.

SmartVirtualization takeover depends fundamentally on storage connectivity, eDevLUN creation/mapping, and multipathing/path migration—not on a universally mandatory Layer-3 route addition.

DR data replication → Storage layer; Service access link → Network layer; Service system operating platform → Host layer; DR policy formulation → DR management layer

Huawei ' s DR technology section identifies replication at the host layer, SAN network layer, and storage array layer. It states that storage-layer DR uses inter-array data replication to replicate data from the local array to the DR array. Network-layer DR places the replication mechanism between application servers and backend storage. For the host layer, the course states that data-replication or switchover software can be installed on hosts in the production and DR centers to form an application-level DR solution. The DR-management function is provided by BCManager/eReplication. Its server performs “DR service process control, DR policy scheduling, and configuration data management of DR resources and services.” Therefore, replication of protected data belongs to the storage layer; connectivity between sites and services belongs to the network layer; the service operating environment belongs to the host layer; and formulation/orchestration of DR policies belongs to the DR-management layer.

The correct default chunk size for the stated 3.84 TB SSD configuration is 8 KB.

The Training Materials describe RAID 2.0+ global pooling as follows: “The system uses RAID 2.0+ to create a global storage pool… All SSDs evenly contribute LUN spaces for back-end SSD sharing.” This explains why storage space is divided into fine-grained units rather than assigning an entire LUN to a fixed RAID group or individual SSD.

Huawei ' s ROW architecture then organizes these units into chunk groups (CKGs). Instead of traditional overwrite behavior, new data and parity are written into a new chunk group and the LBA mapping is redirected to it.

For 3.84 TB SSDs in the configuration tested here, the corresponding default fine-grained chunk size is 8 KB. Options measured in megabytes represent a much coarser allocation unit and do not match this RAID 2.0+ chunk configuration.

The required component is MDC.

OceanStor Pacific uses a distributed control architecture in which cluster-management and metadata/control services must remain highly available as nodes are added, removed, or experience failures. Huawei specifically identifies multi-MDC as a mechanism that improves system reliability. The training architecture also shows MDC participating in sub-health management together with storage-side processes such as OSD and EDS.

This distributed deployment is consistent with the architecture of OceanStor Pacific: storage services are spread across nodes, and control information must remain accessible regardless of the physical node role. The system therefore cannot depend on one isolated control instance.

Huawei also describes OceanStor Pacific as a three-layer scale-out architecture integrating block, file, object, and HDFS services, with cluster-status control, distributed data routing, redundancy management, rebuilding, and balancing forming core storage-engine functions. MDC supports the distributed coordination and control required by this architecture.

The supplied question set identifies MDC as the required abbreviation.
