Free Huawei H13-624_V5.5 Practice Exam with Questions & Answers | Set: 4

The question addresses the configuration process for storage pools in Huawei OceanStor Dorado 18000 series systems. The *HCIP-Storage V5.5 Training Material (Module 4: Storage Design and Implementation)* clarifies: “To create storage pools, an engineer configures the physical disks or disk domains, which serve as the foundation for storage resources. LUNs and LUN groups are created after the storage pool is established, as LUNs are logical divisions of the pool’s capacity. Mapping LUN groups to host groups is a subsequent step to enable host access.” The statement in the question incorrectly suggests that LUNs, LUN groups, and mappings must be configured before creating storage pools, which reverses the actual process. Storage pools are a prerequisite for LUN creation, not the other way around, making the statement 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.

A is true. Huawei’s replication-cluster management documentation states that for capacity reduction, the number of nodes to be removed from a replication cluster must be greater than or equal to 4 . This matches the intent of the statement.

B is false. Huawei provides a Change Name operation for replication clusters, which shows that the replication cluster name can be changed . Therefore, the statement saying the name cannot be changed is incorrect.

C is false. Huawei states that the replication network cannot use the same subnet as other networks , and the replication network also does not share network ports with other networks . Therefore, saying it can share the same subnet is incorrect.

D is true. Huawei’s documentation for changing a replication cluster IP address states that when different replication ports on the same node use IP addresses in the same network segment , the original policy-based route must be deleted before a new policy-based route is configured .

The *HCIP-Storage V5.5 Training Material (Module 5: Storage System Maintenance and Troubleshooting)* lists tenant management roles: “Tenant management roles include tenant administrator, tenant protocol administrator, and tenant data protection administrator, which manage resources, protocols, and data protection tasks within a tenant’s scope.” The security administrator is a system-wide role, not specific to tenant management, as it handles global security policies. Thus, option D is not a tenant management role.

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 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.
