  The Huawei Ocean Protect Appliance leverages CPU core grouping and intelligent scheduling to optimize performance, as described in the *HCIP-Storage V5.5 Training Material (Module 2: Flash Storage Technologies)*. The material states: "CPU core grouping and intelligent scheduling in Ocean Protect appliances enable physical and logical isolation of resources, ensuring that specific cores are dedicated to specific tasks. This isolation reduces contention and minimizes latency for critical operations." This

  directly supports option C, as the technology's primary advantage is reducing latency through resource isolation.

  Option A: Incorrect. While load balancing is a feature of some Huawei storage systems, the training material does not specify that CPU core grouping and intelligent scheduling in Ocean Protect appliances focus on distributing jobs for load balancing. Instead, it emphasizes resource isolation.

  Option B: Incorrect. The material indicates that this technology prevents core overload by isolating tasks, avoiding high latency, making this statement false.

  Option D: Incorrect. Prefetching data and metadata to improve cache hit ratios is unrelated to CPU core grouping and scheduling, which focus on processor resource management, not cache operations.

• Question 113:

  Which statements are false about software Installation of Huawei OceanStor Pacific series storage systems?

  A. To install the Distributed Parallel Client (DPC), the switch configuration is required before the installation regardless of whether the low level design (LLD)- or wizard-based installation mode is selected.
  B. To interconnect with FusionCompute during block service installation, storage and compute nodes must be deployed in converged mode, and the management nodes must be deployed in the virtualization environment.
  C. To interconnect with Huawei Cloud Stack during block service installation, storage and compute nodes must be deployed in converged mode, and the management nodes must be deployed in the virtualization environment.
  D. To install the file service in the standard protocol scenario, the switch configuration is not required throughout the entire installation process.
  D. To install the file service in the standard protocol scenario, the switch configuration is not required throughout the entire installation process.

• Question 114:

  A. DPC supports multi-path concurrent access to storage nodes.
  B. DPC avoids metadata hotspots by distributing metadata requests.
  C. DPC requires the file service to run in performance mode for optimal throughput.
  D. DPC can rewrite file striping policies dynamically without interrupting client I/O.
  D. DPC can rewrite file striping policies dynamically without interrupting client I/O.

  ---

  Striping policies cannot be changed dynamically without affecting service. Modification requires proper scheduling and may involve brief service impact.

• Question 115:

  Assume a government customer purchased several Huawei scale-out storage devices for service deployment. An engineer needs to configure file services in standard protocol scenarios. Which of the following actions does not need to be performed by the engineer during the configuration?

  A. Install DPC.
  B. Create a converged storage pool.
  C. Create namespaces.
  D. Enable the file service for nodes.
  A. Install DPC.

  ---

  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.

• Question 116:

  An industry customer has purchased several Huawei flash storage devices for service deployment. An engineer wants to configure the HyperSnap feature on the storage devices. However, during the configuration, the engineer discovers that snapshots cannot be created for an existing protection group. The possible cause is that the storage pool where the source LUNs in the protection group reside has no available capacity.

  A. TRUE
  B. FALSE
  A. TRUE

  ---

  The HyperSnap feature in Huawei flash storage systems, such as OceanStor Dorado, enables point-in-time snapshots for data protection. The *HCIP-Storage V5.5 Training Material (Module 2: Flash Storage Technologies)* states: "To create snapshots using HyperSnap, the storage pool containing the source LUNs must have sufficient available capacity to store snapshot metadata and copy-on-write (COW) data. If the storage pool lacks free space, snapshot creation for a protection group will fail." This

  aligns with the question' s statement that a lack of available capacity in the storage pool prevents snapshot creation for a protection group, making the statement true. The material emphasizes that capacity issues are a common cause of snapshot failures, as snapshots require additional space for incremental changes.
