Huawei H13-629_V3.0 Exam With Confidence Using Practice Dumps

Huawei ' s storage architecture emphasizes distributed active-active processing, in which requests are distributed across controllers for parallel processing. The course states that adding controllers results in automatic balancing of existing LUN or file-system services and that global cache and pool resources are shared among controllers. The architecture also specifically describes “load balancing among all controllers and auto-rebalancing upon scale-out, failover, and failback.” These principles support A, C, and D. Increasing CPU processing capability addresses compute saturation directly. Adding processing modules or parallel service resources increases the number of resources available to execute service workloads concurrently. Where multiple CPUs or processing resources exist, workload distribution is essential to prevent one processor from becoming saturated while another remains underused.

Reducing the data-block buffer size is not a CPU optimization mechanism. It can instead reduce buffering efficiency and potentially increase I/O-processing overhead.

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.

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.
