Huawei HCIP-Storage V5.5 H13-624_V5.5 Exam Dumps: Updated Questions & Answers (October 2025)

The multi-tenant feature in Huawei’s flash storage systems, such as OceanStor Dorado, is designed to isolate resources for different tenants to ensure data security and privacy. The *HCIP-Storage V5.5 Training Material (Module 2: Flash Storage Technologies)* explains: “The multi-tenant feature isolates both block and file resources, ensuring that tenants cannot access each other’s LUNs or file systems. This is achieved through logical partitioning and access control mechanisms.” The statement in the question claims that tenants cannot access each other’s LUNs but can access each other’s file systems, which contradicts the official documentation. The material emphasizes that file systems, like LUNs, are isolated per tenant, and cross-tenant access is prevented unless explicitly configured (e.g., through shared namespaces, which is not the default behavior). Therefore, the statement 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 SmartEncryption feature in Huawei OceanStor Pacific ensures data security. The *HCIP-Storage V5.5 Training Material (Module 3: Scale-Out Storage Technologies)* explains:

- Option A: True. “For DPC or NFS reads, self-encrypting disks (SEDs) retrieve authentication keys from the key management server, decrypt ciphertext, and return plaintext to the protocol layer.”

- Option B: True. “SmartEncryption supports encrypted writes and decrypted reads via NFS, CIFS, HDFS, and S3 protocols.”

- Option C: False. “SmartEncryption encrypts data at the storage layer. Clients using NFS, CIFS, or DPC write data that is automatically encrypted by the system before storage, not written as plaintext.”

- Option D: True. “OceanStor Pacific uses SEDs for disk-level encryption, ensuring all service data is encrypted.”

Thus, option C is false.

Configuring file services in Huawei scale-out storage systems, such as OceanStor Pacific, involves specific steps for standard protocols like NFS or CIFS. The *HCIP-Storage V5.5 Training Material (Module 4: Storage Design and Implementation)* states: “To configure file services, the engineer must create a converged storage pool to allocate resources, create namespaces for organizing file systems, and enable file services on the relevant nodes. The Distributed Parallel Client (DPC) is optional and used for high-performance parallel file access, not a requirement for standard protocol scenarios.” Let’s evaluate:

- Option A: Not required. DPC is not mandatory for standard file service protocols.

- Option B: Required. A converged storage pool is needed to provide storage capacity.

- Option C: Required. Namespaces organize file service resources.

- Option D: Required. Enabling file services on nodes activates the protocols.

Thus, option A is the action not needed.

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.

Cache watermarks in Huawei flash storage systems manage dirty data flushing. The *HCIP-Storage V5.5 Training Material (Module 5: Storage System Maintenance and Troubleshooting)* explains:

- Option A: True. “The low watermark for dirty data should be around 20% to ensure sufficient buffer space.”

- Option B: True. “The high watermark should not be too high, and the gap between high and low watermarks should be sufficient to avoid frequent flushing.”

- Option C: True. “A high watermark that is too high causes I/O fluctuations and increased latency during traffic bursts.”

- Option D: False. “High watermarks affect write performance by delaying flushes, but low watermarks do not directly impact read performance, which depends on prefetch and cache hit ratios.”

Thus, option D 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.

The deployment of Huawei OceanStor Pacific series involves hardware and software setup. The *HCIP-Storage V5.5 Training Material (Module 5: Storage System Maintenance and Troubleshooting)* explains:

- Option A: False. The material states: “Network initialization for nodes during software deployment can be performed via DeviceManager, the CLI, or the Storage Deployment Tool (SDT), but DeviceManager is not mandatory.” This makes the statement incorrect.

- Option B: True. “SmartKit supports batch OS installation for hardware deployment.”

- Option C: True. “SmartKit can configure clusters, including disabling LLDP and enabling BMC mobile customization.”

- Option D: True. “SmartKit is used to configure BMC settings and verify firmware, OS, and driver versions.”

Thus, option A is false.

The *HCIP-Storage V5.5 Training Material (Module 5: Storage System Maintenance and Troubleshooting)* details the low-level design (LLD) mode for Huawei scale-out storage: “In LLD mode, the Storage Deployment Tool (SDT) is used to plan nodes, networks, and clusters, generating a configuration file that guides subsequent installation and deployment.” The SDT ensures precise configuration for complex deployments, making it the correct tool for this task.
