Free Huawei H13-624_V5.5 Practice Exam with Questions & Answers | Set: 2

The *HCIP-Storage V5.5 Training Material (Module 5: Storage System Maintenance and Troubleshooting)* outlines troubleshooting principles: “Basic troubleshooting principles include prioritizing high-severity alarms, analyzing external factors (e.g., network or host issues) before internal storage issues, and addressing network alarms before network element (NE) alarms to rule out connectivity issues.” Let’s evaluate:

- Option A: Correct principle. Network alarms are analyzed first to exclude external connectivity issues.

- Option B: Not a principle. The material does not prioritize general alarms over specific ones; it focuses on severity and context.

- Option C: Correct principle. Higher-severity alarms are addressed first to mitigate critical issues.

- Option D: Correct principle. External factors are checked before internal storage issues.

Thus, option B is not a basic troubleshooting principle.

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)* confirms: “The CLI command ‘show license_active’ is used to query details of activated licenses on Huawei flash storage systems, including license status and features enabled.” This makes the statement true, as the command is a standard tool for license management.

This question tests knowledge of disk status indicators in Huawei OceanStor Pacific 9950 systems. The *HCIP-Storage V5.5 Training Material (Module 5: Storage System Maintenance and Troubleshooting)* provides details on disk module indicators: “A steady yellow location indicator on a main storage disk module indicates that the disk is faulty or about to fail. This status signals that the disk requires attention, such as replacement, to prevent data loss or service disruption.” The material further clarifies the following for other options:

- Option A: Incorrect. A blinking yellow indicator, not a steady one, typically indicates that the disk is being located (e.g., via DeviceManager or CLI).

- Option B: Incorrect. A steady green indicator signifies that the disk is running properly.

- Option C: Incorrect. A powered-off disk would have no indicator light or a specific power-off signal, not a steady yellow light.

Thus, option D accurately describes the disk’s status.

The *HCIP-Storage V5.5 Training Material (Module 5: Storage System Maintenance and Troubleshooting)* describes user roles in Huawei flash storage systems: “The administrator role is a built-in role with full privileges, including managing users, performing system upgrades, changing the system time, powering off the device, and restarting the device.” This role is designed for comprehensive system management, confirming that the statement is true.

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 stat uses, 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.

A is false. Huawei documentation shows that OceanProtect Backup Storage supports deduplication and compression for both LUNs and file systems , not only for LUNs. The file system creation parameters explicitly include dedup_enabled and compression_enabled, and Huawei’s remote replication command reference also distinguishes both lun and file_system objects on supported models.

B is true, so it is not selected. Huawei’s product highlights state that OceanProtect uses backup data preprocessing and variable-length deduplication to improve logical capacity utilization and reduce TCO. That matches the statement.

C is false. Huawei states that OceanProtect uses a compression algorithm to compress data blocks into smaller data blocks, and then combines and writes them into disks . So the statement is wrong because compression is not simply followed by direct disk writing “without the need to perform any operations”; there is still a combining/write process after compression.

D is false. The statement mixes up fixed-length and content-defined chunking. For fixed-length deduplication, data is divided into blocks of a fixed size , whereas Huawei’s deduplication description emphasizes variable-length deduplication for data reduction. Saying that fixed-length deduplication divides data into fixed-size blocks based on content is incorrect.

SPC (Storage Performance Council) benchmarks are discussed in the *HCIP-Storage V5.5 Training Material (Module 5: Storage System Maintenance and Troubleshooting)*: “SPC-1 tests random I/O workloads, such as OLTP, database, and email scenarios, while SPC-2 tests sequential large I/O access, such as video streaming or backups.” Let’s evaluate:

- Option A: Incorrect. SPC-2 is for sequential large I/Os, not random small I/Os (which is SPC-1).

- Option B: Incorrect. SPC-1 is for random I/Os, not sequential large I/Os.

- Option C: Correct. SPC-2 is designed for sequential large I/O access scenarios.

- Option D: Incorrect. SPC-1, not SPC-2, tests OLTP, database, and email scenarios.

Thus, option C is true.
