Pass the Huawei HCIP-Storage H13-624_V5.5 Questions and answers with CertsForce

This question addresses the behavior of remote replication consistency groups in Huawei storage systems, such as OceanStor Dorado or Pacific series. According to the *HCIP-Storage V5.5 Training Material (Module 4: Storage Design and Implementation)*, a consistency group ensures that multiple remote replication tasks operate as a single unit to maintain data consistency across LUNs or volumes. The material states: “In a remote replication consistency group, if one replication task fails (e.g., due to a link failure or configuration issue), the entire consistency group is affected, and other tasks do not continue running normally. The system suspends all tasks in the group to preserve data consistency until the faulty task is resolved or manually split.” This ensures that dependent data sets remain synchronized. Therefore, the statement that other tasks run normally without waiting for the faulty task is false, as the consistency group halts all tasks to maintain integrity.

The SmartMigration feature in Huawei OceanStor Pacific enables data migration between storage resources. The *HCIP-Storage V5.5 Training Material (Module 4: Storage Design and Implementation)* explains: “The split mode and migration rate of a SmartMigration task can be modified only when the task is in certain statuses, such as Interrupted, Paused, or Faulty. When the task is in the Migrating status, changes to split mode or migration rate are not allowed, as the system is actively transferring data.” This is because modifying parameters during active migration could disrupt the process or cause data inconsistency. Let’s evaluate:

- Option A: Interrupted allows changes, as the task is stopped.

- Option B: Paused allows changes, as the task is temporarily halted.

- Option C: Faulty allows changes, as the task is not actively running.

- Option D: Migrating does not allow changes, as the task is in progress.

Thus, option D is the status that prevents changes.

The *HCIP-Storage V5.5 Training Material (Module 5: Storage System Maintenance and Troubleshooting)* addresses hardware maintenance: “Before removing a faulty interface module, engineers must perform pre-operations, such as disabling the module via DeviceManager or CLI, ensuring no active I/O, and verifying redundancy to avoid service disruption. Direct removal withoutthese steps can cause data loss or system errors.” The statement that the module can be removed without pre-operations is false, as these steps are mandatory.

The Distributed Parallel Client (DPC) in Huawei OceanStor Pacific systems enables parallel file access. The *HCIP-Storage V5.5 Training Material (Module 3: Scale-Out Storage Technologies)* explains: “When adding DPC nodes, engineers can manually add nodes using DeviceManager by entering the management IP address of the node, not the service IP address. The management IP is used to establish control plane communication for node integration.” The service IP address is used for data access by clients, not for node creation or management tasks. Therefore, the statement that the engineer can add a node using the service IP address is false.

The *HCIP-Storage V5.5 Training Material (Module 5: Storage System Maintenance and Troubleshooting)* describes the tools used for Huawei storage system deployment: “The Storage Deployment Tool (SDT) is designed to streamline software installation for Huawei storage systems. SDT collects and evaluates compatibility information in a one-stop manner and supports batch installation of UltraPath, the multipathing software, enhancing installation efficiency.” The SDT automates and simplifies deployment tasks, making it the correct tool for this description.

The HyperMetro feature in Huawei OceanStor Pacific series provides active-active storage with high availability. The *HCIP-Storage V5.5 Training Material (Module 4: Storage Design and Implementation)* states: “HyperMetro supports incremental synchronization. In the event of a site failure, the site that wins arbitration (via quorum server or static priority) continues services in single-write mode. After the faulty site recovers, HyperMetro resumes dual-write mode and synchronizes incremental data generated during the fault to the recovered site, ensuring data consistency.” This process ensuresminimal data loss and seamless recovery, making the statement true. The material emphasizes that incremental synchronization reduces the bandwidth and time required compared to full synchronization.

The *HCIP-Storage V5.5 Training Material (Module 5: Storage System Maintenance and Troubleshooting)* details management tools:

- Option A: False. “SmartKit is used for hardware inspection, OS installation, and firmware upgrades, but it does not provide alarm reporting, file upload, or remote access capabilities.”

- Option B: True. “DeviceManager supports resource allocation, user management, data protection, performance monitoring, and alarm management.”

- Option C: True. “DME IQ provides cloud-based management, remote maintenance, and predictive analytics.”

- Option D: True. “The CLI supports all listed functions, including resource allocation and alarm management.”

Thus, option A is false.

The HyperMetro feature in Huawei storage systems, such as OceanStor Dorado, provides active-active data access with arbitration mechanisms to handle site failures. The *HCIP-Storage V5.5 Training Material (Module 4: Storage Design and Implementation)* details HyperMetro arbitration modes:

- Option A: True. The material states: “In the absence of a quorum server, HyperMetro operates in static priority mode, where the preferred site is designated to win arbitration and continue services during a failure.”

- Option B: True. The material explains: “In static priority mode, if the preferred site fails, the non-preferred site does not automatically take over to avoid split-brain scenarios. Services stop, and manual intervention is required to forcibly start services on the non-preferred site.”

- Option C: False. The material clarifies: “In quorum server mode, the quorum server can be deployed on physical machines or virtual machines, provided it meets the performance and network requirements.” This makes the statement that it can only be deployed on physical machines incorrect.

- Option D: True. The material confirms: “In quorum server mode, if the link between storage systems fails, both systems send arbitration requests to the quorum server to determine which site continues providing services.”

Thus, option C is false.
