H13-624_V5.5 Exam Dumps - Huawei HCIP-Storage Questions and Answers

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.

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 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.

The *HCIP-Storage V5.5 Training Material (Module 5: Storage System Maintenance and Troubleshooting)* outlines troubleshooting principles: “Basic troubleshooting principles include prioritizing high-severity alarms, analyzing external factors (e.g., network or host issues) before internal storage issues, and addressing network alarms before network element (NE) alarms to rule out connectivity issues.” Let’s evaluate:

- Option A: Correct principle. Network alarms are analyzed first to exclude external connectivity issues.

- Option B: Not a principle. The material does not prioritize general alarms over specific ones; it focuses on severity and context.

- Option C: Correct principle. Higher-severity alarms are addressed first to mitigate critical issues.

- Option D: Correct principle. External factors are checked before internal storage issues.

Thus, option B is not a basic troubleshooting principle.

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.
