H13-624_V5.5 HCIP-Storage V5.5 Questions and Answers

This statement is true . Huawei’s official HyperReplication configuration procedure states that before adding a remote device, you must create an authentication user on the remote device , and the role of that user must be “Remote device administrator.” After that, the engineer can use that account and password when adding the remote device .

Huawei’s documentation for adding a remote device explicitly says that the Remote Device Administrator account and password must be set to the authentication user created on the remote device . This directly matches the statement in the question.

A is correct. Huawei’s secure boot description states that secure boot uses public/private key pairs and digital signatures to sign and verify boot modules, ensuring integrity and preventing unauthorized tampering of system software during startup.

B is correct. Huawei describes secure boot as a chain-of-trust startup process in which the previous module verifies the next module level by level . Only after verification succeeds does the next module run and the device continue booting.

C is incorrect. Huawei training material for storage secure boot shows the sequence as: (1) verify the Grub signature public key, (2) verify and load Grub, (3) verify software signature certificate status, (4) verify and load the OS . Therefore, this option gives the wrong order.

The HyperCDP (Continuous Data Protection) feature in Huawei all-flash storage, like OceanStor Dorado, provides high-frequency snapshots. The *HCIP-Storage V5.5 Training Material (Module 2: Flash Storage Technologies)* states:

- Option A: True. “HyperCDP snapshots can be used for data analysis, application testing, and backup, as they provide consistent point-in-time copies.”

- Option B: True. “After a HyperCDP snapshot is created, write requests to the source LUN use copy-on-write (COW) technology, storing new data in a new storage pool location and updating the source LUN’s pointer.”

- Option C: False. The material clarifies: “HyperCDP snapshots can be directly mapped to hosts as read-only LUNs, without requiring file system sharing, for accessing point-in-time data.”

- Option D: False. “HyperCDP is optimized for high-density snapshots with low memory overhead, using metadata structures rather than full file system objects.”

Thus, options A and B are true.

This statement is true . The NVM Express organization explains that NVMe over Fabrics (NVMe-oF) extends NVMe across fabric technologies such as Fibre Channel (FC) and RDMA-based transports , including RoCE, InfiniBand, and iWARP . It also notes support for TCP transport.

So the listed transports in the question — Fibre Channel, InfiniBand, RoCE v2, iWARP, and TCP — are valid NVMe-oF transport options

This question addresses the behavior of remote replication during a primary/secondary switchover in Huawei flash storage systems, such as OceanStor Dorado. The *HCIP-Storage V5.5 Training Material (Module 4: Storage Design and Implementation)* explains: “During a primary/secondary switchover in remote replication, the secondary site becomes the primary site and starts accepting write I/Os. The original primary site, if available, becomes the secondary site. Data changes are tracked incrementally, but full synchronization does not occur automatically after the switchover unless explicitly configured or triggered by a fault recovery process.” The question’s statement that “all data will be synchronized” implies an automatic full synchronization, which is not the default behavior. Instead, only incremental changes are synchronized when replication resumes, making the statement 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.

The correct answer is SmartQoS . Huawei’s OceanStor Pacific documentation states that SmartQoS supports OPS and bandwidth upper limit control by namespace, account, and client IP address . This matches the question exactly.

In static priority mode , when the inter-site link goes down, Huawei states that the preferred site wins arbitration and continues providing services, while the non-preferred site stops providing services. The HyperMetro pair status changes to "To be synchronized" because real-time synchronization is interrupted by the link failure.

Since equipment room A is the preferred site , after the link failure:

the volume in equipment room A continues providing services ,

the volume in equipment room B stops providing services ,

and the pair status is "To be synchronized" .

Therefore, Option B is correct.

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 statement is true. Huawei’s HyperClone documentation states that reverse synchronization is supported only when the secondary LUN capacity is greater than or equal to the primary LUN capacity. In this question, the secondary LUN is 20 GB and the primary LUN is 10 GB, so the capacity condition for reverse synchronization is met.

Huawei also states that during reverse synchronization, the capacity of the primary LUN cannot be expanded. This directly matches the second part of the statement.

The Direct TCP Offload Engine (DTOE) 1.0 is a performance optimization feature in Huawei flash storage systems. The *HCIP-Storage V5.5 Training Material (Module 2: Flash Storage Technologies)* explains: “DTOE 1.0 offloads TCP processing from the CPU to dedicated hardware, reducing CPU resource consumption and latency. It operates in user mode to manage hardware queues, avoiding context switching overhead, and uses polling mode to minimize interrupt latency. Unlike traditional TCP processing, DTOE eliminates kernel mode interrupts, locks, system calls, and thread switching.” Let’s evaluate:

- Option A: False. DTOE offloads MAC frame processing to hardware, not the CPU, reducing CPU resource usage.

- Option B: True. The material confirms that DTOE operates in user mode, avoiding context switching.

- Option C: True. Polling mode is used to reduce latency, as stated in the material.

- Option D: False. DTOE eliminates kernel mode overheads like interrupts and system calls, contrary to the statement.

Thus, options A and D are false.

Huawei describes CPU core grouping and intelligent scheduling as improving processing performance by using core grouping and task partitioning, which aligns with resource isolation and lower latency , not cache prefetch across all LUNs.

This statement is false . Huawei’s official OceanStor Dorado networking documentation states that quorum links must be established on GE, 10GE, or 25GE networks, but not on a Fibre Channel network . Therefore, it is incorrect to say that only 10GE can be used and that 25GE cannot be used .

Huawei’s SmartIO interface module documentation also explicitly states that 10 Gbit/s and 25 Gbit/s SmartIO interface modules can be used for HyperMetro quorum links . This directly confirms that 25GE is supported for quorum networking. Fibre Channel, however, is not supported for quorum links.

So the correct judgment is:

10GE → supported

25GE → supported

Fibre Channel → not supported

Hence, the overall statement is FALSE .

Huawei states that SmartCompression is suitable for data that is stored in the same format but contains little duplicate data , because it can save storage space and reduce costs.

The *HCIP-Storage V5.5 Training Material (Module 5: Storage System Maintenance and Troubleshooting)* addresses controller faults in Huawei flash storage systems, such as OceanStor Dorado: “A faulty controller is a critical issue that requires immediate attention, as it can impact system performance, redundancy, or availability. Even if the fault is common (e.g., a single controller failure in a dual-controller setup), emergency handling is necessary to replace the controller and restore full redundancy to prevent potential service disruptions.” The statement that no emergency handling is needed is false, as controller faults always warrant prompt action to ensure system reliability.

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.

This question pertains to Quality of Service (QoS) features in Huawei OceanStor Pacific series storage systems. The *HCIP-Storage V5.5 Training Material (Module 3: Scale-Out Storage Technologies)* describes: “The OceanStor Pacific series supports the traffic shaping feature, which uses the classic token bucket algorithm to control the upper limit of traffic. When tokens in the bucket are insufficient, the system generates and adds tokens based on the operations per second (OPS) and bandwidth limits defined for the QoS control object.” Traffic shaping regulates data flow to prevent network congestion and ensure fair resource allocation, making it the correct feature name for this description.

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.

Configuring iSCSI block services on Huawei scale-out storage, like OceanStor Pacific, involves specific steps. The *HCIP-Storage V5.5 Training Material (Module 4: Storage Design and Implementation)* states: “To enable iSCSI block services, the engineer must create a block storage pool to allocate storage resources and configure the iSCSI service to set up initiator-target relationships and network parameters.” Let’s evaluate:

- Option A: Required. A block storage pool is necessary to provide the capacity for iSCSI LUNs.

- Option B: Required. Configuring the iSCSI service is essential to enable the protocol and connectivity.

- Option C: Not required. DPC is used for file services, not iSCSI block services.

- Option D: Not required. DPC installation is unrelated to iSCSI configuration.

Thus, options A and B are mandatory.

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.

Option B is correct. Huawei documentation on SmartVirtualization explains that when no value-added feature is configured for an eDevLUN, the local storage system only needs to consume a small amount of space, mainly for metadata management. Therefore, each eDevLUN occupies only a small amount of space in the local storage pool.

Option C is also correct. Huawei states that eDevLUNs are created based on storage pools on the local storage system. This means eDevLUNs belong to storage pools created locally, even though the actual external capacity comes from the heterogeneous storage.

Option A is incorrect because it reverses the roles of the two storage systems. In SmartVirtualization, the actual data resides on the external/heterogeneous storage system , while the local storage system mainly stores metadata and provides management for value-added services. The option states the opposite, so it is false.

Option D is incorrect because Huawei requires the external LUN to be in a normal state before an eDevLUN can be created. If the external LUN is abnormal, the eDevLUN creation condition is not met. Therefore, eDevLUNs cannot be created regardless of external LUN status.

Huawei’s official OceanProtect functional architecture describes the Data enablement engine as providing global search and data anonymization functions, which matches option D.

Option A is incorrect because ProtectManager is the management module , while backup, restore, replication, archive, and copy mount belong to the data protection layer/data flow functions , not ProtectManager.

Option B is incorrect because file system management and protocol access are provided by the basic storage service/basic storage layer , not the data protection layer.

Option C is incorrect because OceanProtect Appliance supports protecting application data through its protection ecosystem, but the statement “without backup agents” is not the functional-architecture definition that matches this question. The architecture item explicitly matched in Huawei material is the DataEnable Engine description in option D
