Pass the Huawei HCIE-Storage H13-629_V3.0 Questions and answers with ExamsMirror

The virtual firewall capability in the DCS multi-tenant architecture provides security-policy enforcement inside the virtualized data-center environment. This includes controlling access to tenant/VPC resources, grouping or applying common access policies to cloud servers with equivalent trust and protection requirements, and enforcing permit/deny behavior through mechanisms such as blacklist and whitelist rules. Therefore, A, B, and D correspond to firewall/security-policy functions.

The HCIE Lab Guide establishes that a DCS design must provide intranet/extranet isolation and division of security zones, with security measures applied according to the protection requirements of those zones. The Training Materials also place network and security resources under the virtualized data-center architecture managed by DME/FusionCompute.

Option C belongs to a different security function. The course describes VPN technologies as connectivity mechanisms—for example IPsec VPN, L2TP VPN, GRE VPN, and MPLS VPN—used to establish secure network connectivity between sites or remote networks. It is therefore not the virtual firewall function being tested.

The OceanStor Pacific architecture states: “Storage engine layer: implements persistent storage.” It further specifies that this layer provides “erasure coding (EC), data rebuilding and balancing, disk management, and data read/write capabilities.”

Therefore, C. Data reconstruction belongs to the engine layer.

Option A, tiered storage, is implemented as an advanced storage-service capability through features such as SmartTier, meaning it belongs logically to the service layer rather than the persistence engine. Option B, protocol interworking, is associated with service/interface processing. Huawei specifically describes multi-protocol access and interworking for NFS, CIFS, POSIX, MPI, S3, and HDFS in the interface/service architecture.

Option D, service configuration, is part of storage management, alongside installation, deployment, user management, device management, alarm reporting, monitoring, upgrade, and capacity expansion.

The architectural separation is therefore clear: interfaces expose protocols; the service layer implements storage services and value-added functions; the engine layer provides persistent storage, redundancy, rebuilding, balancing, and disk I/O; and management performs administrative operations.

Data migration solution based on MigrationDirector for Object → File system layer; Data migration solution based on LVM → Volume management layer; Data migration solution based on the migration function of the virtualization platform → Operating system layer; Data migration solution based on HyperMetro → Storage network layer

The supplied practice-set answer maps the four migration approaches as shown above. Huawei’s migration architecture organizes migration technologies according to where the migration function is implemented in the host/storage stack. LVM-based migration operates through host volume management, while virtualization-platform migration uses capabilities supplied by platforms such as VMware or FusionCompute. HyperMetro/HyperReplication-based migration operates at the storage-network/storage-system level and moves or mirrors storage data independently of application logic.

There is one important source inconsistency in this item: the official Training Materials’ “Technical Structure of Huawei Storage Migration Solutions” explicitly places Migration Director for Object under the Object layer, while it separately associates the file-system layer with NAS migration. Therefore, the first match in the supplied question key does not align with the official training diagram.

For this practice set, the answer above reproduces the supplied key; for study purposes, remember that Huawei’s official architecture classifies object migration at the Object layer.

The statement is FALSE because it incorrectly places the application-side backup plug-in inside the OceanProtect appliance.

Huawei ' s OceanProtect architecture separates the ProtectManager/DataMoveEngine components on the protection system from ProtectClient components that protect application data on hosts. The course specifically states that ProtectClient protects host application data and that the application being protected determines which agent software is installed.

The database-protection workflow therefore uses OceanProtect to schedule and coordinate the job, while application-aware operations are performed through the client/agent located with the protected database environment. In analogous Huawei database workflows, DataMoveEngine creates backup storage space, instructs ProtectClient to start the backup operation, ProtectClient mounts the storage space, and the host-side application plug-in invokes the database-specific backup mechanism.

Thus, even though Oracle RMAN is Oracle ' s native backup/recovery technology, saying that an RMAN plug-in in the appliance directly invokes the database interface misrepresents the architecture. Application-aware execution occurs through the protection client/agent associated with the Oracle host.

The HCIE training material describes LAN-free networking with a SAN between the CNA nodes, production storage, eBackup server, and backup infrastructure. It explicitly states that when virtualized SAN storage is used and LAN-free networking is required for backup and recovery, storage LUNs must be mapped to the eBackup server.

Therefore, the correct answer is B. SAN storage.

LAN-free backup is designed to move backup and recovery traffic over the storage network instead of the production Ethernet LAN. Huawei states that this approach is particularly suitable when the data volume is large and the backup window is strict because backup and recovery do not consume Ethernet resources.

For FusionCompute, the production LUNs can be directly exposed through the storage path to the eBackup backup server/proxy. This differs from LAN-based backup, where the backup system obtains data through the CNA node over the LAN. The direct SAN path is the technical condition that produces the “only LAN-free backup and restoration” behavior described in the scenario.

Huawei divides DR into data-level, application-level, and service-level protection according to recovery requirements and investment.

For data-level DR, the remote site primarily protects copies of production data. Huawei explicitly states that a data-level DR center cannot prevent service interruption when a disaster occurs; it operates essentially as a backup center from which data can later be restored. Therefore, C is correct and D is false.

For application-level DR, the backup site contains the same application system as the production site and data is synchronized between the sites using synchronous or asynchronous mechanisms. This allows applications to be restarted at the DR site within the defined RTO, making B correct.

Service-level DR is the most comprehensive level. Huawei defines it as a complete DR environment covering IT technologies and infrastructure as well as non-IT resources such as offices and telecommunications. A redundant workplace may therefore be required if the normal business site becomes unavailable.

Hence, A, B, and C are correct.

Huawei states that after a remote replication pair is configured, “the secondary LUN is read-only by default.” If the primary LUN fails, the administrator can cancel write protection and make the secondary LUN writable so that the secondary storage system takes over host services.

Therefore, the statement is TRUE.

The default read-only behavior protects the DR copy from independent host modifications while normal replication is maintained. In a disaster situation, however, the secondary storage may need to become the active service provider. Removing secondary-LUN write protection enables DR-side hosts to perform both reads and writes against the protected copy.

Huawei specifically identifies this function as useful when a conventional primary/secondary switchover cannot be executed normally after failure of the production array. Once the secondary LUN has accepted new production writes, those changes are tracked so that subsequent incremental synchronization can support recovery and switchback.

This design shortens recovery time while preserving the normal protection model: read-only during ordinary replication, manually writable when DR takeover is required.

The statement is FALSE because it attributes guarantees for CPU, memory, and I/O resources collectively to CPU QoS.

CPU QoS applies to the allocation and scheduling of CPU computing resources. Memory and I/O are distinct resource classes and are controlled through their own resource-management mechanisms. A CPU QoS policy cannot by itself guarantee the VM ' s minimum memory allocation and storage/network I/O resources.

Huawei ' s FusionCompute architecture explicitly separates compute virtualization management, storage virtualization management, and network virtualization management, reflecting the fact that these resource domains are managed independently. The Lab Guide likewise demonstrates separate resource reservation parameters for CPU and memory, configuring “Reserved CPU (%)” and “Reserved Memory (%)” independently rather than treating memory as part of CPU QoS.

FusionCube combines compute, virtualization, networking, and scale-out storage into a unified platform, but convergence does not eliminate the distinction between their QoS controls.

Therefore, CPU QoS can protect or regulate CPU computing capability, but it does not independently guarantee CPU, memory, and I/O resources together. The overall statement is consequently FALSE.

Huawei states that the default UltraPath settings are recommended for most scenarios. At the controller level, UltraPath supports load balancing between controllers or within a controller. At the link level, the supported modes are explicitly listed as “round-robin, min-queue-depth, and min-task.”

Therefore, the statement is FALSE. FIFO is not listed as an UltraPath link load-balancing algorithm in the HCIE training material. Furthermore, changing a load-balancing algorithm is not the appropriate corrective action when only certain hosts cannot access a LUN that is successfully mapped to multiple hosts. That symptom requires checking the affected hosts ' paths, initiators, mapping relationships, SAN/iSCSI connectivity, and UltraPath path status.

Huawei defines min-queue-depth as the default link-level algorithm: UltraPath selects the available path with the smallest number of outstanding I/Os. Round-robin distributes I/Os across available paths sequentially, whereas min-task chooses the path carrying the least I/O data volume.

Huawei explains that when a LUN snapshot is created and activated, “a data copy that is identical to the source LUN is generated.” The snapshot subsequently preserves data associated with that specific snapshot state.

The statement is therefore FALSE because a snapshot is fundamentally a point-in-time protection mechanism. It can recover data to the state represented by an available clean snapshot, but this does not automatically mean zero data loss. Any valid production changes written after the latest clean snapshot and before the ransomware incident may not exist in the restored snapshot.

The course makes the point-in-time property explicit for snapshot technology: snapshot data remains consistent with the source at the snapshot creation point.

Zero-data-loss protection is associated with technologies that synchronously maintain another valid copy, such as HyperMetro or synchronous replication, rather than ordinary scheduled snapshots. Consequently, snapshots can be highly effective for ransomware recovery when a clean recovery point exists, but the achievable RPO depends on the available snapshot protection points.
