Huawei H13-629_V3.0 Practice Exam Questions & Answers

The SmartVirtualization offline-takeover workflow states: ''Step 2: Disconnect the application server from the heterogeneous storage system to stop data transfer and services. Step 3: Connect the application server to the local storage system and enable the local storage system to take over services.'' The takeover-mode section further states that offline takeover uses no masquerading and is applicable to compatible Huawei and third-party heterogeneous storage systems; importantly, services on the related application servers are stopped temporarily. For migration implementation, services must therefore first be stopped. The original source-storage mapping is then changed so that host access can be redirected correctly. SmartVirtualization subsequently takes over the source LUNs. After the host paths and service relationship have been transferred to Huawei storage, applications and services are restored. SmartMigration can then move the actual data from the heterogeneous eDevLUN to the target internal LUN while Huawei storage controls host access.

Consequently, the sequence is b a c e d, or baced.

Huawei states that database backup ''supports full backup, incremental backup, differential backup, and log backup.'' It further specifies: ''By using log backup, production data can be recovered to any time point in the past,'' and that the solution supports ''data encryption, backup data transmission encryption, and storage encryption'' as well as ''traffic control.''

Therefore, A, C, and D are correct.

Point-in-time recovery is enabled by combining database backup copies with transaction/archive log backup. Instead of being restricted to a full or incremental backup timestamp, the restore workflow can replay the required logs until the requested recovery time, thereby reducing the effective RPO.

Encryption is supported across multiple stages: backup data itself can be encrypted, backup-data transmission can be protected, and the underlying storage can use encryption. Traffic control is also supported so that backup activity does not consume excessive network or storage bandwidth and interfere with production services.

Data cleaning, option B, is not listed among the database backup capabilities described in this course section.

Huawei states: ''SmartEqualizer calculates the load based on the configured load policy and returns the IP address of a proper node to the client so that the client can access the storage system using the standard protocol.''

This directly supports C. SmartEqualizer performs access-layer load balancing when clients resolve and access storage services. It does not rely on all cluster nodes continuously pushing their load information to one designated ''primary SmartEqualizer node'' in the manner described in A; therefore A is incorrect.

The SmartEqualizer service integrates with DNS-based client access. Huawei supports two DNS deployment approaches: client-side DNS can forward the required OceanStor Pacific domain-resolution request to the storage system's DNS service, or a client can use the OceanStor Pacific DNS address directly. These operating approaches correspond to B and D.

This DNS-based mechanism is important because the IP returned to a new client is selected according to the configured balancing policy, allowing new access sessions to be distributed across suitable nodes instead of concentrating service traffic on one storage node.

The only true statement is C, so the false statements are A, B, and D.

Huawei states: ''If communication between the storage systems is down, the preferred site continues to provide services while the other site stops providing services.''

The HyperMetro pair therefore transitions to To be synchronized because the two storage systems can no longer maintain synchronous dual-write consistency across the failed inter-site link.

Option A is false because automatic fallback to static priority mode is associated with quorum-server failure, not merely failure of the HyperMetro communication link while the quorum server remains available. Option D is false because permitting both sites to continue independently would create a split-brain risk. Quorum arbitration exists specifically to prevent that condition.

Option B is also false because arbitration does not simply make both sides unavailable. One site wins arbitration and continues providing services, while the losing site stops host access.

This behavior preserves data consistency until the inter-site link is repaired and synchronization resumes.

Huawei identifies MigrationDirector for SAN as the dedicated migration tool for SAN storage migration. Before migration execution, the migration environment must be defined: the source storage must be identified, the relevant service host must be known, and the target storage/resources must be prepared.

The Lab Guide's workflow places Creating a Service Host, Configuring the Source Storage, and Preparing the Target Storage before the actual Data Migration phase. A SmartVirtualization migration lab follows the same structure: production/service-host preparation and target-storage preparation precede takeover and data migration.

This makes A, B, and C configuration/preparation activities.

Option D belongs later in migration execution. Huawei's migration delivery sequence explicitly places target-storage configuration and migration preparation before stopping services, taking over the source storage, recovering applications, and migrating data.

Therefore, service takeover is an implementation/cutover activity rather than information entered during migration-task configuration.

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.
