Assume a financial customer purchased several Huawei OceanStor Pacific scale-out storage devices for service deployment, and an engineer has configured the file service in the Distributed Parallel Client (DPC) on the storage devices. To meet service requirements, the engineer needs to enable the CPU performance mode for the DPC node. Which of the following commands cannot be used to enable the performance mode?
Correct Answer: D
The command "set cpu frequency -g performance" is not a valid Linux or Huawei-specific command for managing CPU performance modes. The other commands are valid ways to query or set CPU frequency and performance modes on Linux-based systems.
H13-624_V5.5 Exam Question 2
When delivering a Huawei flash storage project, an engineer introduced the SAN/NAS integrated architecture to the customer. Which of the following statements is false about the architecture?
Correct Answer: B
In the SAN/NAS integrated architecture, both NAS protocols and iSCSI can leverage TCP offload capabilities depending on the network hardware and configuration. It is incorrect to state that only NFS/CIFS supports DTOE while iSCSI does not, so this statement is false.
H13-624_V5.5 Exam Question 3
If a performance issue occurs in Huawei flash storage, an engineer can perform optimization operations according to the storage performance optimization process. Which of the following statements is false about the performance optimization process?
Correct Answer: D
The optimization operation phase focuses on making targeted configuration adjustments to address identified performance bottlenecks. It does not require deploying disaster recovery for the service system, and configuration changes should be made in a controlled and incremental manner rather than modifying multiple configurations at the same time.
H13-624_V5.5 Exam Question 4
Huawei OceanStor Pacific series storage systems provide a recycle bin function. When a storage system deletes an old dentry, it records a write-ahead log (WAL) twice. In addition, after the dentry is deleted, the inode is also deleted.
Correct Answer: B
In OceanStor Pacific recycle bin design, when a dentry is deleted, the system records WAL entries to ensure reliability, but the inode is not immediately deleted because it must be retained for possible recovery from the recycle bin.
H13-624_V5.5 Exam Question 5
In scale-out storage, the erasure code (EC) mechanism provides good redundancy protection for data. Which of the following statements are false about the EC mechanism? (Choose all that apply.)
Correct Answer: B,D
Node-level security does not have the highest space utilization because additional redundancy is required across nodes, and disks on a faulty node are not directly taken over in a way that reduces the fault impact scope as described. Increasing the EC parameter N is not supported after services are stopped, because EC parameters are fixed once the disk pool is created and cannot be modified by simply stopping services.
