H13-629_V3.0 Exam Dumps and Practice Questions

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.

Huawei describes DME IQ as supporting ''remote maintenance and installed base operation.'' It collects alarms, performance information, configurations, system logs, and disk information as the data foundation for intelligent O&M.

The full-lifecycle O&M architecture also places DME IQ on the intelligent prediction, remote O&M, online site deployment, and planning-simulation side of the Huawei data-management framework. DME IQ therefore directly supports remote O&M, installed-base operations, and delivery/maintenance-oriented activities.

Service Change, however, is associated primarily with DME Storage's data-center management and orchestration capabilities, rather than being one of the principal DME IQ functions. The DME Storage product architecture explicitly lists Service Change, O&M Management, Data Protection, and Data Flow as its operational domains.

DME IQ may analyze or simulate changes---for example workload migration or rollout---but executing service changes and resource orchestration belongs to DME/DME Storage. Consequently, D is the required answer.

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 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 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.
