That is, N data blocks and M parity blocks are stored in different cabinets. If M nodes or M disks are faulty, the system can still read and write data without service interruption or data loss. If M cabinets are faulty, services may be interrupted. Options: A. TRUE B. FALSE Answer: A Explanation: The statement describes the reliability mechanism of Huawei’s scale-out storage systems, such as the OceanStor Pacific series, which employ cabinet-level security to enhance data availability. According to the *HCIP-Storage V5.5 Training Material (Module 3: Scale-Out Storage Technologies)*, scale-out storage systems use distributed architectures with N data blocks and M parity blocks stored across different cabinets to ensure redundancy. This design leverages erasure coding (EC) or similar mechanisms to tolerate faults. The material explicitly states: “In a scale-out storage system, N+M redundancy ensures that if up to M nodes or M disks fail, the system can reconstruct data withoutinterruption or loss. However, if M cabinets fail, the system may lose the ability to access sufficient parity or data blocks, potentially interrupting services.” This confirms that the system can handle M node or disk failures without issue, but M cabinet failures may disrupt services due to the loss of distributed data or parity blocks. Therefore, the statement is true.

During actual service running, the customer discovers that there are multiple running statuses for a remote replication pair. Which of the following statements is true about the running status of a pair? Options: A. After a pair is disconnected, if the pair is deleted from the primary or secondary site, which causes configuration inconsistency between the primary and secondary sites, the pair running status changes to "To be recovered." B. When the pair running status is "Split," the pair relationship between the primary and secondary LUNs is interrupted (not manually). C. When the pair running status is "Normal," data synchronization between the primary and secondary LUNs is complete. D. When the pair running status is "To be synchronized," the pair relationship between the primary and secondary LUNs must be manually disconnected to meet the service requirements of a single LUN. Answer: C Explanation: 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: Storage Design 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. Reference: Huawei Huawei H13-624_V5.5 PDF https://www.certification-exam.com/ HCIP-Storage V5.5 Training Material, Module 4: Storage Design and Implementation, Section 4.3: Remote Replication Configuration and Management*, Huawei Technologies Co., Ltd. --- Question 3 After purchasing a Huawei OceanStor Dorado series storage system, a customer needs to configure basic storage services in the storage system. Which of the following operations are optional in the basic service configuration? Options: A. Configuring connectivity between a host and the storage system B. Creating a port group C. Creating a mapping D. Creating a LUN group Answer: B, D Explanation: 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.

This feature isolates service data. Although different tenants cannot access each other’s LUNs, they can access each other’s file system. Options: A. TRUE B. FALSE Answer: B Explanation: 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. Reference: HCIP-Storage V5.5 Training Material, Module 2: Flash Storage Technologies, Section 2.4: Multi- Tenancy and Resource Isolation*, Huawei Technologies Co., Ltd. --- Question 5 Huawei OceanStor Pacific series is an intelligent scale-out storage product that supports large-scale scale-out and delivers high reliability. Which of the following statements are false about the product’s reliability? Options: A. In terms of data reliability, multiple RAID policies are supported based on the traditional disk- level RAID mode. B. The product adopts Kunpeng processors to integrate functions of multiple chips and effectively improve hardware reliability. C. The product leverages link aggregation to ensure transmission link redundancy and performs link switchover or isolation to ensure service continuity if a link becomes faulty or subhealthy. Huawei Huawei H13-624_V5.5 PDF https://www.certification-exam.com/ D. The product uses the multi-copy technology to implement the intra-node RAID function. If a node is faulty, the system reliability is not degraded and even remains higher than that of the EC mechanism. Answer: A, D Explanation: This question tests knowledge of the reliability features of the Huawei OceanStor Pacific series, as covered in the *HCIP-Storage V5.5 Training Material (Module 3: Scale-Out Storage Technologies)*. Let’s evaluate each option: - Option A: False. The training material states: “OceanStor Pacific uses advanced erasure coding (EC) and multi-copy technologies for data reliability, moving beyond traditional disk-level RAID modes.” While RAID-like concepts may be used internally, the system primarily relies on distributed EC or replication, not traditional RAID, making this statement inaccurate. - Option B: True. The material confirms: “Kunpeng processors integrate multiple chip functions, reducing points of failure and enhancing hardware reliability.” This is a correct statement. - Option C: True. The material notes: “Link aggregation ensures transmission link redundancy, with automatic switchover or isolation for faulty or subhealthy links, maintaining service continuity.” This is accurate. - Option D: False. The material clarifies: “Multi-copy technology ensures data redundancy across nodes, but it does not implement intra-node RAID. If a node fails, reliability depends on inter-node copies or EC, and it is not necessarily higher than EC mechanisms, which are optimized for distributed systems.” This makes the statement false, as it misrepresents the technology and its comparative reliability. Thus, options A and D are false. Reference: HCIP-Storage V5.5 Training Material, Module 3: Scale-Out Storage Technologies, Section 3.3: OceanStor Pacific Reliability Features*, Huawei Technologies Co., Ltd. Question 6 Huawei Ocean Protect Appliance adopts the key technology of CPU core grouping and intelligent scheduling, which is widely used by customers in many industries. Which of the following is the advantage of this technology? Options: A. The scheduler can distribute jobs to other cores based on the service load status, implementing load balancing. B. When this technology is used to carry different services, some cores are overloaded, resulting in high latency. C. This technology implements physical and logical isolation of resources, reducing latency. Huawei Huawei H13-624_V5.5 PDF https://www.certification-exam.com/ D. The system can prefetch data and metadata from all LUNs, improving the cache hit ratio. Answer: C Explanation: Huawei describes CPU core grouping and intelligent scheduling as improving processing performance by using core grouping and task partitioning, which aligns withresource isolation and lower latency, not cache prefetch across all LUNs. Question 7 A government customer has purchased two Huawei flash storage devices and deployed them in different data centers for running remote replication services. When a primary/secondary switchover is performed for the remote replication pair, the primary and secondary sites record the data changes. When the secondary site becomes the primary site following the primary/secondary switchover, all data will be synchronized between the primary and secondary sites. Options: A. TRUE B. FALSE Answer: B Explanation: 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.

The back-end shared interface module of OceanStor Dorado 18000 is inserted into the enclosure. The disk enclosure connected to the interface module can be accessed by controllers in the engine at the same time. B. Dorado V6 series and new converged storage products use the PCIe Scale-Out architecture. C. OceanStor Dorado 18000 uses 200 Gbit/s RDMA shared interface modules for cross-engine expansion, implementing full interconnection between 8, 12, and 16 controllers. D. OceanStor Dorado 18000 supports a maximum of 28 interface modules and implements intra- engine mirroring and cross-engine interconnection through the 100 Gbit/s RDMA network. Answer: C Explanation: This question tests knowledge of the Huawei OceanStor Dorado series architecture, as covered in the *HCIP-Storage V5.5 Training Material (Module 2: Flash Storage Technologies)*. Let’s evaluate each option: - Option A: True. The material confirms: “The back-end shared interface module of OceanStor Dorado 18000 is inserted into the enclosure, allowing simultaneous access to disk enclosures by all controllers in the engine.” - Option B: True. The material states: “Dorado V6 series and converged storage products adopt the PCIe Scale-Out architecture for high-performance interconnects.” - Option C: False. The material specifies: “OceanStor Dorado 18000 uses 100 Gbit/s RDMA shared interface modules for cross-engine expansion, supporting full interconnection between 8, 12, and 16 controllers.” The claim of 200 Gbit/s RDMA is incorrect, as 100 Gbit/s is the standard for Dorado 18000. - Option D: True. The material notes: “OceanStor Dorado 18000 supports up to 28 interface modules and uses a 100 Gbit/s RDMA network for intra-engine mirroring and cross-engine interconnection.” Thus, option C is false due to the incorrect RDMA speed.

SmartMigration is configured to migrate services from a source LUN to a target LUN without interrupting host services. Which of the following statements about this feature is false? Huawei Huawei H13-624_V5.5 PDF https://www.certification-exam.com/ Options: A. The implementation of a SmartMigration task between heterogeneous storage systems depends on the LUN takeover function provided by SmartVirtualization. B. When configuring this feature, you must plan the capacities of the source and target LUNs. The capacity of the target LUN must be greater than or equal to that of the source LUN. C. When configuring this feature, you cannot use a LUN that has been mapped to an application server as the target LUN of a SmartMigration task. D. The higher the migration rate, the better the host service performance is. Therefore, the highest migration rate can be used when the host service load is heavy. Answer: D Explanation: The SmartMigration feature in Huawei OceanStor Dorado enables seamless data migration between LUNs, as detailed in the *HCIP-Storage V5.5 Training Material (Module 4: Storage Design and Implementation)*. Let’s analyze each option: - Option A: True. The material states: “SmartMigration between heterogeneous storage systems relies on SmartVirtualization to take over the source LUN, ensuring compatibility and seamless migration.” - Option B: True. The material confirms: “The target LUN capacity must be greater than or equal to the source LUN capacity to accommodate all data during migration.” - Option C: True. The material notes: “A LUN already mapped to an application server cannot be used as the target LUN for SmartMigration, as it would disrupt existing mappings.” - Option D: False. The material explains: “The migration rate affects system resources. Setting the highest migration rate under heavy host service load can degrade performance due to resource contention. The rate should be adjusted based on load to minimize impact.” This makes the statement false, as high migration rates are not recommended during heavy loads. Thus, option D is false.

When configuring basic object services on the storage systems, an engineer discovers that the object service cannot be enabled for storage nodes. Which of the following is not a possible cause? Options: A. The engineer has manually adjusted the time of the cluster nodes. As a result, the conflict Huawei Huawei H13-624_V5.5 PDF https://www.certification-exam.com/ handling is different. B. NTP synchronization is not configured for the cluster, and different NTP time sources are used. C. Namespaces with the same name have been created under the same account. D. The Network Time Protocol (NTP) clock in the storage cluster is inconsistent with the clock of the client that accesses object services. Answer: C Explanation: This question addresses issues with enabling object services in Huawei OceanStor Pacific 9550 systems, as covered in the *HCIP-Storage V5.5 Training Material (Module 3: Scale-Out Storage Technologies)*. The material outlines prerequisites for enabling object services, including time synchronization. Let’s evaluate: - Option A: Possible cause. The material states: “Manual time adjustments on cluster nodes can cause inconsistencies in conflict handling, preventing object services from being enabled.” - Option B: Possible cause. The material notes: “Lack of NTP synchronization or use of different NTP sources can lead to time discrepancies, causing object service failures.” - Option C: Not a cause. The material clarifies: “Namespaces with the same name under the same account are allowed in OceanStor Pacific, as they are managed uniquely per tenant or bucket.” This does not prevent object service enablement. - Option D: Possible cause. The material confirms: “Inconsistent NTP clocks between the storage cluster and client can disrupt object service operations, as time synchronization is critical for protocols like S3.” Thus, option C is not a possible cause.
