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

Huawei scale-out storage, like OceanStor Pacific, uses multiple network planes. The *HCIP-Storage V5.5 Training Material (Module 3: Scale-Out Storage Technologies)* states:

- Option A: True. “The internal management network handles communication for deployment, upgrades, resource configuration, alarms, and certificate updates.”

- Option B: False. “In DPC scenarios, the back-end storage network is used for internal communication between storage nodes and OSDs, not for DPC-to-OSD data transfer, which occurs over the service network.”

- Option C: True. “The management network connects to the customer’s management infrastructure for system administration.”

- Option D: True. “The service network interfaces with applications via S3, HDFS, NFS, CIFS, and POSIX.”

Thus, option B is false.

This question addresses the process of adding DPC nodes in Huawei OceanStor Pacific systems. The *HCIP-Storage V5.5 Training Material (Module 3: Scale-Out Storage Technologies)* states: “To add DPC nodes, engineers can use DeviceManager to either manually add nodes by entering the management IP address or batch import nodes using a template. For manual addition, the management IP address is required to establish communication with the node. For batch import, a template must be downloaded, filled with node details, and uploaded to complete the process. Authentication is required in both modes to ensure secure node addition.” Let’s evaluate:

- Option A: False. Authentication is required for both manual and batch methods to validate node addition.

- Option B: True. The material confirms that the management IP address is required for manual node addition.

- Option C: False. The service IP address is not used for node addition; the management IP is needed.

- Option D: True. The material describes the batch import process as requiring a filled template upload.

Thus, options B and D are true.

SmartDedupe and SmartCompression are data reduction technologies in Huawei all-flash storage systems, such as OceanStor Dorado. The *HCIP-Storage V5.5 Training Material (Module 2: Flash Storage Technologies)* provides details:

- Option A: True. The material states: “Post-process compression involves writing data to storage media first, then reading it back for compression during idle periods.”

- Option B: True. The material confirms: “Inline deduplication divides data into blocks and calculates fingerprints to identify duplicates before writing.”

- Option C: False. The material clarifies: “Similarity-based deduplication, whether inline or background, requires dividing data into blocks to calculate fingerprints for similarity detection. Direct calculation without block division is not supported.” This makes the statement incorrect.

- Option D: True. The material notes: “Backup storage supports deduplication and compression for file systems to optimize space usage.”

Thus, option C is false.

The question focuses on the running statuses of remote replication pairs in Huawei’s flash storage systems, such as OceanStor Dorado. The *HCIP-Storage V5.5 Training Material (Module 4: StorageDesign and Implementation)* details the remote replication feature and its statuses. The material states: “When the pair running status is ‘Normal,’ the remote replication pair is fully synchronized, meaning data between the primary and secondary LUNs is consistent, and synchronization is complete.” This matches option C.

- Option A: Incorrect. The training material indicates that if a pair is deleted from one site, causing inconsistency, the status may not necessarily change to “To be recovered.” Instead, it may require manual intervention or reconfiguration, and “To be recovered” is typically associated with link failures or incomplete synchronization, not deletion.

- Option B: Incorrect. The “Split” status occurs when the pair relationship is interrupted, but it can be due to manual intervention or automatic triggers (e.g., link failure). The parenthetical “not manually” is misleading, as the material does not restrict “Split” to non-manual causes.

- Option D: Incorrect. The “To be synchronized” status indicates that the pair is preparing for synchronization but is not yet consistent. There is no requirement to manually disconnect the pair for single LUN service needs, as the system can operate with the primary LUN independently during this state.

Thus, option C is the only accurate statement based on official documentation.

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

- Option A: True. “Correct expansion cable connections are required before power-on to ensure proper operation.”

- Option B: True. “The BMC system allows powering on controller enclosures via the external management IP when none are powered on.”

- Option C: False. “After an emergency power-off, the storage system is powered on via DeviceManager, CLI, or BMC, not by pressing the controller enclosure’s power button, which is used for normal power-on.”

- Option D: True. “In OceanStor Dorado 8000, powering on a controller enclosure automatically powers on cascaded disk enclosures.”

Thus, option C is false.

The *HCIP-Storage V5.5 Training Material (Module 5: Storage System Maintenance and Troubleshooting)* addresses performance issue demarcation: “If the latency on the compute side is significantly higher than on the storage side, the issue is likely outside the storage system, such as in the host, network, or application layer. If the storage side showed high latency (e.g., due to disk performance limits), it would be reflected in the STORAGE metrics.” The statement incorrectly attributes the issue to the storage system, as higher compute-side latency points to external factors, making it false.

The HyperClone feature in Huawei OceanStor Dorado systems creates full data copies for reliability and testing. The *HCIP-Storage V5.5 Training Material (Module 2: Flash Storage Technologies)* states: “HyperClone creates a full copy of a source LUN to a target LUN. A source LUN can form multiple HyperClone pairs with different target LUNs. Data copying starts at synchronization, but hosts must wait for the copy to complete before accessing the target LUN. HyperClone supports bidirectional synchronization, allowing data restoration from target to source. For block storage, it uses redirect-on-write (ROW), while file system clones use copy-on-write (COW).” Let’s evaluate:

- Option A: False. The material confirms that a source LUN can form multiple HyperClone pairs with different target LUNs.

- Option B: False. Hosts cannot access the target LUN until the copy process completes, contrary to the statement.

- Option C: True. Bidirectional synchronization is supported, including restoration from target to source.

- Option D: True. The material distinguishes ROW for block clones and COW for file system clones.

Thus, options A and B are false.

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.

This question pertains to the configuration of basic storage services in Huawei OceanStor Dorado series storage systems. According to the *HCIP-Storage V5.5 Training Material (Module 4: Storage Design and Implementation)*, basic service configuration involves essential steps to enable storage access for hosts. The material outlines the following:

- Configuring connectivity between a host and the storage system (Option A) is mandatory, as it involves setting up physical or logical connections (e.g., Fibre Channel or iSCSI) to allow the host to communicate with the storage system. Without this, no storage services can be accessed.

- Creating a mapping (Option C) is also mandatory, as it maps LUNs to hosts or host groups, enabling the host to access specific storage resources. The material states: “Mapping is a critical step to associate LUNs with hosts for service access.”

- Creating a port group (Option B) is optional. Port groups are used to organize front-end ports for specific purposes (e.g., load balancing or zoning), but they are not always required, especially in simpler configurations where default port settings suffice.

- Creating a LUN group (Option D) is optional. LUN groups simplify management by grouping multiple LUNs for mapping, but they are not mandatory if LUNs are mapped individually.

Thus, options B and D are optional operations, as they are not always required for basic service configuration.

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.
