• Question 1:

  In Huawei scale-out storage, which statement about the service network is true?

  A. The service network handles client access for protocols such as NFS, CIFS, HDFS, and S3.
  B. The service network is used only for node-to-node intercommunication.
  C. The service network must use a dedicated Layer 3 topology and cannot use VLANs.
  D. The service network transmits only control traffic, not data traffic.
  A. The service network handles client access for protocols such as NFS, CIFS, HDFS, and S3.

  ---

  Explanation

  The service network provides external data access for file, object, and POSIX workloads.

• Question 2:

  An Industry customer has purchased several Huawei flash storage devices for service deployment. An engineer wants to configure the HyperReplication feature on the storage devices. During the configuration, the engineer needs to create an authentication user with the role of "Remote device administrator" on the remote device and then add the remote device.

  A. TRUE
  B. FALSE
  A. TRUE

• Question 3:

  FILL IN THE BLANK The performance of a storage system can be measured by multiple indicators. In application scenarios where the I/O size is greater than or equal to 64 KB, the ________ performance indicator is the main concern for storage performance.

  Throughput

  Explanation:

  Storage performance metrics are covered in the *HCIP-Storage V5.5 Training Material (Module 5: Storage System Maintenance and Troubleshooting)*: "For large I/O sizes (#64 KB), throughput is the primary performance indicator, as it measures the data transfer rate, critical for applications like video streaming or large file transfers." Throughput, measured in MB/s or GB/s, reflects the system's ability to handle large data volumes, making it the key concern for such scenarios.

• Question 4:

  To power off a storage system, you need to stop host services, power off controller enclosures, and then disconnect external power supplies.

  A. TRUE
  B. FALSE
  A. TRUE

• Question 5:

  After a remote replication consistency group is created, if one remote replication task is faulty, other tasks in the consistency group run normally without waiting for the faulty task to recover.

  A. TRUE
  B. FALSE
  B. FALSE

  ---

  This question addresses the behavior of remote replication consistency groups in Huawei storage systems, such as OceanStor Dorado or Pacific series. According to the *HCIP-Storage V5.5 Training Material (Module 4: Storage Design and Implementation)*, a consistency group ensures that multiple remote replication tasks operate as a single unit to maintain data consistency across LUNs or volumes. The material states: "In a remote replication consistency group, if one replication task fails (e.g., due to a

  link failure or configuration issue), the entire consistency group is affected, and other tasks do not continue running normally. The system suspends all tasks in the group to preserve data consistency until the faulty task is resolved or manually split." This ensures that dependent data sets remain synchronized. Therefore, the statement that other tasks run normally without waiting for the faulty task is false, as the consistency group halts all tasks to maintain integrity.

• Question 6:

  A customer deploys CSI storage in Kubernetes using Huawei storage. Which statement about the CSI Node component is true?

  A. CSI Node runs as a StatefulSet.
  B. CSI Node is responsible for mount and unmount operations.
  C. CSI Node configures storage pools on Huawei storage.
  D. CSI Node is optional when deploying CSI.
  B. CSI Node is responsible for mount and unmount operations.

  ---

  Explanation

  CSI Node runs as a DaemonSet and performs node-level mount/unmount operations. Storage provisioning is handled by the CSI Controller.

• Question 7:

  When deploying Huawei OceanStor Dorado all-flash storage, an engineer enables SmartPrioritize to optimize latency-sensitive workloads. Which of the following statements about SmartPrioritize is false?

  A. SmartPrioritize identifies latency-sensitive I/Os and processes them preferentially.
  B. SmartPrioritize dynamically allocates CPU and cache resources based on workload characteristics.
  C. SmartPrioritize replaces SmartQoS, and both features cannot be used together.
  D. SmartPrioritize reduces jitter for critical services by isolating resource interference.
  C. SmartPrioritize replaces SmartQoS, and both features cannot be used together.

  ---

  SmartPrioritize and SmartQoS are independent system features. SmartPrioritize focuses on latency-sensitive workload acceleration, while SmartQoS controls bandwidth and IOPS. They can be used concurrently. Therefore, the statement that SmartPrioritize replaces SmartQoS is false.

• Question 8:

  A financial customer purchases Huawei OceanStor Pacific 9950 for service deployment. During a routine inspection, an engineer finds that a main storage disk of the device is faulty and uses SmartKit to replace it. Which of the following statements is true about replacing the disk?

  A. When removing the disk, the engineer needs to remove it from its connector, wait at least 60 seconds, and then remove the disk from the chassis.
  B. Before using SmartKit to replace the disk, the engineer needs to complete the pre-processing as prompted. After that, the engineer can continue the subsequent operations.
  C. The duration from removing the main storage disk to installing a normal one on the node cannot exceed 10 minutes. Otherwise, heat dissipation of the storage device will be affected.
  D. The interval between removing the faulty disk and inserting a normal one is at least 10 seconds. Otherwise, the disk may be damaged.
  B. Before using SmartKit to replace the disk, the engineer needs to complete the pre-processing as prompted. After that, the engineer can continue the subsequent operations.

  ---

  Disk replacement in Huawei OceanStor Pacific 9950 is covered in the *HCIP-Storage V5.5 Training Material (Module 5: Storage System Maintenance and Troubleshooting)*: "SmartKit guides disk replacement, requiring engineers to complete pre-processing steps, such as isolating the faulty disk and verifying redundancy, before proceeding with removal and installation." Let's evaluate:

  Option A: Incorrect. The material does not specify a 60-second wait after disconnecting the disk; it emphasizes immediate removal after pre-processing.

  Option B: Correct. The material confirms that SmartKit prompts for pre-processing (e.g., disabling the disk) before replacement.

  Option C: Incorrect. There is no 10-minute limit for heat dissipation concerns; the focus is on quick replacement to minimize reconstruction time.

  Option D: Incorrect. No specific 10-second interval is required to prevent disk damage; the material advises prompt insertion after removal.

• Question 9:

  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?

  A. The protocol layer is responsible for protocol parsing and permission management. SAN and NAS are two sets of semantic logic. Therefore, different service entry components are used.
  B. The space management layer uses the active-active high reliability mode to provide reliable data protection capabilities based on actual service scenarios of customers.
  C. The software architecture consists of the following layers from top to bottom: protocol, data service, cache, file and block space management, and storage pool.
  D. At the protocol layer, NFS/CIFS supports direct TCP offload engine (DT06), while ISCSI does not.
  D. At the protocol layer, NFS/CIFS supports direct TCP offload engine (DT06), while ISCSI does not.

• Question 10:

  An engineer configures QoS policies on Huawei OceanStor Dorado. Which of the following is not a valid QoS control metric supported by the system?

  A. Bandwidth
  B. IOPS
  C. Latency upper limit
  D. CPU frequency limit
  D. CPU frequency limit

  ---

  QoS supports bandwidth, IOPS, and latency constraints. CPU frequency is not a QoS-controlled metric.
