Huawei H13-624_V5.5 問題集

質問 1：
Which statements are false about software Installation of Huawei OceanStor Pacific series storage systems?
A. 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.
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 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.
D. To install the file service in the standard protocol scenario, the switch configuration is not required throughout the entire installation process.
正解：D

質問 2：
A financial customer has purchased multiple Huawei OceanProtect Backup Storage devices for service data backup protection. Which of the following statements are false about the data reduction principle of OceanProtect Backup Storage? choose all that apply
A. In the data reduction process, backup data is divided into blocks of a fixed size based on its content for fixed-length deduplication.
B. In the data reduction process, the system performs backup data preprocessing and then variable-length deduplication.
C. The backup storage can perform deduplication and compression for LUNs but not for file systems.
D. The backup storage performs feature-based compression for different application data. After compression, the data can be directly written to disks without the need to perform any operations.

質問 3：
A government customer has purchased several Huawei OceanStor Pacific series storage devices. An engineer wants to install the distributed parallel client (DPC) on the storage devices. The operations before DPC installation have been completed. Now, the engineer needs to add DPC nodes. Which of the following statements are true about adding nodes?
A. If the engineer selects "Manually Add Node" on DeviceManager, the engineer must enter the management IP address of the node to be added.
B. If the engineer selects "Manually Add Node" on DeviceManager, the engineer must enter the service IP address of the node to be added.
C. If the engineer selects "Batch Import Node" on DeviceManager, the engineer must fill in the downloaded template, and upload the template to complete batch import.
D. The engineer can add nodes by batch importing nodes or manually adding nodes. In either mode, authentication is not required.

質問 4：
When delivering a flash storage project, Huawei engineers introduced the arbitration mechanism of HyperMetro to the customer. Which of the following statements is false about the arbitration modes?
A. In quorum server mode, the quorum server can be deployed only on physical machines and not on virtual machines.
B. In static priority mode, if the preferred site of a HyperMetro pair breaks down, the non-preferred site does not automatically take over HyperMetro services. As a result, the services stop, and the customer must forcibly start the services at the non-preferred site.
C. If no quorum server is configured, HyperMetro works in static priority mode. When an arbitration occurs, the preferred site wins the arbitration and provides services.
D. In quorum server mode, if the link between storage systems is down, each storage system sends an arbitration request to the quorum server.

質問 5：
A financial customer purchases a Huawei OceanStor Pacific 9950 storage device for service deployment. Engineers have configured basic block storage services on the device. During an O&M management process, an engineer needs to modify the attributes of a storage pool. Which of the following attributes will not be modified?
A. Actual location of the storage pool
B. Capacity alarm threshold
C. Storage pool name
D. Hot spare policy of the storage pool
正解：A

質問 6：
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 software architecture consists of the following layers from top to bottom: protocol, data service, cache, file and block space management, and storage pool.
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 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.
D. At the protocol layer, NFS/CIFS supports direct TCP offload engine (DT06), while ISCSI does not.
正解：D

質問 7：
In Huawei flash storage, the integrated I/O stack of SAN and NAS can be divided into the storage pool layer, space management layer, and data service layer. Which of the following are performance concerns of the space management layer?
A. Whether failover is enabled for protocol receiving threads
B. CPU usage of metadata background management
C. Hit ratio of the prefetch algorithm
D. Cache hit ratio of hot metadata
正解：B,D

質問 8：
A financial customer has purchased several Huawei OceanStor Pacific 9550 storage systems. When configuring basic object services on the storage systems, an engineer discovers that the object service cannot be enabled for storage nodes. Which of the following is not a possible cause?
A. The engineer has manually adjusted the time of the cluster nodes. As a result, the conflict handling is different.
B. Namespaces with the same name have been created under the same account.
C. NTP synchronization is not configured for the cluster, and different NTP time sources are used.
D. The Network Time Protocol (NTP) clock in the storage cluster is inconsistent with the clock of the client that accesses object services.
正解：B
