Free Practice Questions for Huawei H13-629_V3.0 Exam

The correct selections are IPMI, RESTful, and Redfish.

Huawei describes DME as “the unified management software integrating software and hardware for data centers” and states that it controls, manages, and analyzes VMs, datastores, databases, servers, switches, and storage devices.

For API-oriented integration, RESTful is explicitly part of Huawei ' s DME architecture. The storage-management course states that the open southbound system manages storage, switch, and host resources through management protocols including RESTful.

IPMI and Redfish provide the hardware-management interfaces required when the management platform interacts with server/BMC infrastructure. Redfish supplies a modern REST-oriented hardware-management model, while IPMI provides established out-of-band platform-management functions.

Telnet is not selected. It is a legacy plaintext terminal protocol and is not an appropriate protocol for the hardware/API interconnection functions being tested in this DME management architecture.

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.

Study Guide Topics: Data Protection Solution → OceanProtect Backup → Host File Backup → NAS File Backup → LAN-Base → NFS/SMB Protection.

The Huawei flash-storage feature table defines SmartThin as “Intelligent thin provisioning.” Therefore, when the provisioning type is configured for thin provisioning, the associated feature is SmartThin.

The DME Storage course separately states that block-storage service levels support resource-tuning policies for Thin/Thick mode, deduplication and compression, and SmartTier. These are separate resource-tuning dimensions.

SmartTier concerns data placement among storage tiers, SmartCompression performs data reduction by compression, and SmartDedupe eliminates duplicate data. None of those features defines whether a LUN is thinly or thickly provisioned. SmartThin is specifically the capacity-allocation technology that exposes a logical capacity while allocating physical storage according to actual consumption.

Thus, among the four choices, SmartThin is the license/feature corresponding to the requested provisioning type.

The retrieved course material clearly maps SmartThin to intelligent thin provisioning and DME to Thin/Thick resource tuning; the exact licensing dialog wording is not separately reproduced in the parsed Training/Lab pages.

The mapping follows Huawei ' s separation of business continuity, data recoverability, and long-term retention.

The course states: “DR ensures business continuity. Backup focuses on data recoverability. Archiving is for long-term storage of cold data and regulatory compliance.”

Remote replication combined with BCManager eReplication addresses site-level disaster recovery, and Huawei states that BCManager provides one-click DR drill and switchover capabilities.

HyperMetro is the appropriate solution for storage-level continuity because Huawei defines it as an active-active storage solution using dual-write technology to provide service continuity and zero data loss.

When continuous availability must extend to the application layer, storage HyperMetro must be combined with an application cluster so that application processing itself can fail over seamlessly.

Finally, backup protects against logical corruption, accidental deletion, and malware-related damage because historical copies remain available independently of production data.

Study Guide Topics: Data Protection Basics → DR vs Backup → HyperMetro → Remote Replication → BCManager eReplication → Application-Level HA.

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.

Huawei defines the DR-drill procedure as: stop the production application and unmap hosts/LUNs → synchronize incremental data → switch the replication relationship → map a LUN → start DR applications → test whether applications start successfully.

Therefore, A, B, and D are the required operations.

Incremental synchronization ensures that the DR copy has the latest protected changes before the service transition. The replication relationship is then switched so the DR-side storage resources can assume the required service role. After the target LUNs are mapped, DR applications are started and tested to confirm that the recovery environment can actually carry the business workload.

Option C is different. A recovery plan must already be defined as part of BCManager DR configuration and orchestration; formulating the recovery plan is not an execution step performed every time a DR drill runs. The course separately describes eReplication configuration as creating protection groups and recovery plans before recovery operations are executed.

A DR drill therefore validates an existing DR design and recovery plan rather than redesigning that plan during each test.

The flash-storage course describes database applications as having 8 KB I/O, with random reads accounting for 70%, and identifies OLTP as a workload suitable for caching hot, random small-I/O data.

The financial-file material also states that small-file aggregation is applicable to “small check image files in carrier and financial scenarios.” This is inconsistent with option C ' s characterization of document imaging as being dominated by GB-level large-file writes.

Financial OLTP workloads are highly transactional and typically produce small, random I/O with identifiable hot regions, which matches the training material ' s OLTP/SmartCache model. Backup and archiving workflows are throughput-oriented and therefore favor larger sequential transfers, while restoration reverses the dominant direction toward reads. OLAP workloads process substantial datasets and consequently emphasize large sequential read operations.

The directly retrieved training passages do not reproduce the complete four-row financial workload table verbatim, but they specifically support the OLTP pattern and contradict the large-file characterization in option C.

Huawei ' s LUN-discovery troubleshooting procedure explicitly lists “Cause 1: The storage pool is faulty” and “Cause 2: The link is abnormal.” For an abnormal link, DeviceManager is used to check whether the connected FC or iSCSI port reports Link down. The separate multipathing troubleshooting section states that multipathing malfunction generally leads to storage performance deterioration or failure to discover multiple paths. Typical causes include the multipathing software being blocked or the HBA driver having its own failover function. Therefore, the complete absence of multipathing software does not inherently prevent a Linux host from detecting a mapped LUN through an available single path. Multipathing primarily provides path aggregation, redundancy, failover, and load balancing.

By contrast, a faulty storage pool can make the LUN unavailable; incorrect FC zoning prevents the host initiator from reaching storage targets; and an actual physical or logical link fault prevents device discovery. Consequently, option A is the false statement.

The required feature is SmartMobility.

The function implements policy-driven movement of file data according to its value or activity level. Frequently accessed, performance-sensitive data remains on the local primary storage, while colder data can be relocated to remote storage resources. The objective is to preserve high performance for active data while reducing the cost of retaining less frequently accessed information.

Huawei characterizes next-generation hybrid flash storage as supporting “Free warm and hot data flow” and states that “Warm and hot data can be migrated in a gateway-free, software-free, and cross-device manner.”

The broader tiering architecture similarly describes policy-based classification of hot, warm, and cold data and automated migration according to storage policies. This enables the physical location of cold data to change without requiring the application to manage the movement manually.

SmartMobility extends that lifecycle principle to file-service scenarios in which cold file data is migrated away from the primary system to suitable remote devices while the frequently accessed portion remains local.
