H13-624_V5.5 Huawei Exam Lab Questions

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.

Syslog configuration in Huawei flash storage systems enables alarm and event logging. The *HCIP-Storage V5.5 Training Material (Module 5: Storage System Maintenance and Troubleshooting)* explains:

- Option A: False. “Syslog configuration does not require SNMP or USM user setup, as Syslog operates independently for log forwarding.”

- Option B: True. “The ‘show notification syslog’ command displays the Syslog configuration, including content format.”

- Option C: True. “The ‘change syslog-notification format_type=cef’ command sets the Syslog format to Common Event Format (CEF).”

- Option D: False. “If the Syslog server uses certificates, the storage system must import the server’s CA certificate to establish secure communication.”

Thus, options A and D are false.

The software installation process for Huawei OceanStor Pacific scale-out storage systems is detailed in the *HCIP-Storage V5.5 Training Material (Module 3: Scale-Out Storage Technologies)*. Let’s evaluate each option:

- Option A: True. The material states: “For block service installation with converged compute and storage nodes, each node requires at least 20 vCPUs to support management and data processing tasks.”

- Option B: True. The material confirms: “In converged deployments, the disk quantity difference between any two nodes in a storage pool must not exceed 2 or 30% of the disk count on the node with the most disks to ensure balanced performance.”

- Option C: False. The material explains: “Wizard-based software installation automates node addition, network configuration, and control cluster creation via DeviceManager, reducing manual steps. Engineers do not need to perform these tasks manually before installing the OceanStor Pacific software.” This makes the statement incorrect.

- Option D: True. The material notes: “DPC installation requires a minimum of 20 GB of memory on compute nodes to ensure stable operation.”

Thus, option C is false.

Changing the management network port IP in Huawei flash storage systems is a common initialization task. The *HCIP-Storage V5.5 Training Material (Module 5: Storage System Maintenance and Troubleshooting)* states:

- Option A: False. “The CLI command to change the management IP is ‘change system management_ip_address,’ not ‘change system management_ip.’”

- Option B: True. “Management and maintenance network ports must use different network segments to avoid routing conflicts.”

- _Index C: False. “No license is required to change the management network port IP address; it is a basic configuration task.”

- Option D: True. “For serial port login, the maintenance terminal’s IP and the default management IP must be in the same segment to establish connectivity.”

Thus, options A and C are false.
