Question 4

When delivering a Huawel OceanStor Pacific scale-out storage project, an engineer introduced the end-to-end data Integrity check technology of scale-out storage to the customer. Which of the following statements are false about this technology?

AThis technology enables the storage system to implement periodic background data integrity check. When the service load is heavy or service access is frequent, the system automatically starts periodic background data integrity check and self-healing.

BFor silent data scenarios such as bit change and read offset, the end-to-end data integrity check technology supports logical block addressing (LBA) check of clusters and hosts.

CBlock, NAS, and object services support end-to-end data integrity check, but the HDF5 service does not.

DIn this technology, write requests are checked at the system entry (virtual block service). User data is checked again in the object storage device (OSD) before being written to disks. Data Is written to disks only after the data integrity check succeeds.

Correct Answer: A. This technology enables the storage system to implement periodic background data integrity check. When the service load is heavy or service access is frequent, the system automatically starts periodic background data integrity check and self-healing.

Question 5

An industry customer has purchased two Huawei OceanStor Pacific scale-out storage devices and deployed them in different equipment rooms. Now an engineer wants to configure the HyperMetro feature on the two devices in static priority mode. Equipment room A is the preferred site. After the link between the two storage devices is down, what is the running status of the HyperMetro pair and what is the arbitration result?

AThe running status of the HyperMetro pair is 'Normal'. The arbitration result is that the volume in equipment room A is inaccessible and that in equipment room B continues providing services.

BThe running status of the HyperMetro pair is 'To be synchronized'. The arbitration result is that the volume in equipment room A continues providing services and that in equipment room B stops providing services.

CThe running status of the HyperMetro pair is 'Normal'. The arbitration result is that the volumes in equipment rooms A and B continue providing services.

DThe running status of the HyperMetro pair is 'To be synchronized'. The arbitration result is that the volume in equipment room A is inaccessible and that in equipment room B stops providing services.

Correct Answer: B. The running status of the HyperMetro pair is 'To be synchronized'. The arbitration result is that the volume in equipment room A continues providing services and that in equipment room B stops providing services.

Explanation:

Instatic priority mode, when the inter-site link goes down, Huawei states that thepreferred site wins arbitrationand continues providing services, while thenon-preferred site stopsproviding services. TheHyperMetro pair status changes to 'To be synchronized'because real-time synchronization is interrupted by the link failure.

Sinceequipment room A is the preferred site, after the link failure:

the volume inequipment room A continues providing services,

the volume inequipment room B stops providing services,

and the pair status is'To be synchronized'.

Therefore,Option Bis correct.

Question 6

During routine inspection, an engineer of a bank finds that an interface module of a Huawei flash storage device is faulty. In this case, the engineer can directly remove and insert the interface module without any pre-operations.

ATRUE

BFALSE

Correct Answer: B. FALSE

Explanation:

The *HCIP-Storage V5.5 Training Material (Module 5: Storage System Maintenance and Troubleshooting)* addresses hardware maintenance: ''Before removing a faulty interface module, engineers must perform pre-operations, such as disabling the module via DeviceManager or CLI, ensuring no active I/O, and verifying redundancy to avoid service disruption. Direct removal without these steps can cause data loss or system errors.'' The statement that the module can be removed without pre-operations is false, as these steps are mandatory.

Question 7

When deploying a Huawei converged storage system, engineer A uses the UltraPath software. Which of the following statements are false about the load balancing algorithms of UltraPath?

AThe min-queue-depth algorithm refers to the minimum queue depth algorithm. UltraPath is configured with this algorithm by default.

BRound robin is a min-task algorithm and can be used in scenarios where service I/O model data blocks delivered by the host are large.

CThe min-task algorithm is a round robin algorithm and can be used in scenarios where the service I/O models delivered by the host have little difference.

DThe algorithms fall into three types: min-queue-depth, round-robin, and min-task.

Correct Answer: B. Round robin is a min-task algorithm and can be used in scenarios where service I/O model data blocks delivered by the host are large.

Question 8

A financial customer purchased an OceanStor Dorado 18000 storage system for basic service deployment. During management, an engineer discovered that the running status of an iSCSI port on DeviceManager was "Link down". After checking the indicator in the equipment room, the engineer discovered that the link indicator of the iSCSI front-end port was steady red. Which of the following are not the possible causes of the exception?

AThe optical module type is incompatible with the host port.

BThe IP address of the iSCSI front-end port is incorrect.

CThe cable between the application server and the storage device is loose.

DThe IP address of the service network port on the application server is incorrectly set.

Correct Answer: B. The IP address of the iSCSI front-end port is incorrect.; D. The IP address of the service network port on the application server is incorrectly set.

Explanation:

Huawei's troubleshooting guidance foriSCSI Link Failurestates that when therunning status of an iSCSI host/front-end port is ''Link down''and thelink indicator is steady red or off, the fault is investigated as aphysical/link-layer problem. Huawei's documented possible causes include items such ascables between the host and storage being removed or damaged,optical module faults/incompatibility, orfront-end port faults.

Therefore,Acan be a possible cause because Huawei has a specific fault case for anincompatible optical module typecausing the port to be unavailable.Ccan also be a possible cause because Huawei explicitly listscables removed or damaged/looseas a cause of the link-down condition.

BandDarenotpossible causes of this specific exception. Incorrect IP settings on either thestorage iSCSI front-end portor theapplication server service network portarenetwork-layer configuration issues, but they donotcause the physical link indicator to turnsteady redor the port running status to becomeLink down. A physical link-down alarm points to hardware, cabling, or optical-module problems instead.

Question 9

Assume a financial customer purchases a Huawei OceanStor Pacific scale-out storage system for future service deployment. Which statement is false about software installation of the storage system?

ADuring block service installation, if management nodes are deployed where compute and storage nodes are converged, the number of vCPUs on each converged compute and storage node must be greater than or equal to 20.

BDuring block service installation, if converged deployment of storage and compute nodes is required, the difference between the disk quantities on any two nodes in the same storage pool cannot be greater than 2 or 30% of the disk quantity on the node having most disks.

CIf wizard-based software installation is used, an engineer must manually add nodes, configure networks, and create a control cluster on DeviceManager, and then install the OceanStor Pacific series software.

DTo install the Distributed Parallel Client (DPC), the memory required for running the DPC software on a compute node must be greater than or equal to 20 GB.

Correct Answer: C. If wizard-based software installation is used, an engineer must manually add nodes, configure networks, and create a control cluster on DeviceManager, and then install the OceanStor Pacific series software.

Explanation:

The software installation process for Huawei OceanStor Pacific scale-out storage systems is detailed in the *HCIP-Storage V5.5 Training Material (Module 3: Scale-Out Storage Technologies)*. Let's evaluate each option:

- Option A: True. The material states: ''For block service installation with converged compute and storage nodes, each node requires at least 20 vCPUs to support management and data processing tasks.''

- Option B: True. The material confirms: ''In converged deployments, the disk quantity difference between any two nodes in a storage pool must not exceed 2 or 30% of the disk count on the node with the most disks to ensure balanced performance.''

- Option C: False. The material explains: ''Wizard-based software installation automates node addition, network configuration, and control cluster creation via DeviceManager, reducing manual steps. Engineers do not need to perform these tasks manually before installing the OceanStor Pacific software.'' This makes the statement incorrect.

- Option D: True. The material notes: ''DPC installation requires a minimum of 20 GB of memory on compute nodes to ensure stable operation.''

Thus, option C is false.

Question 10

Assume an enterprise customer purchased several Huawei flash storage devices for service deployment. An engineer needs to configure Syslog notification on the storage system. Which of the following statements are false about configuration operations?

ADuring the configuration, the engineer needs to configure the SNMP protocol and USM users in the storage system for receiving and querying system alarms.

BTo view the display format of Syslog content, the engineer can run the 'show notification syslog' command.

CTo change the display format of Syslog content to CEF, the engineer can run the 'change syslog-notification format_type=cef' command.

DIf certificates and CA certificates are generated on the Syslog server, the engineer does not need to perform any operation in the storage system.

Correct Answer: A. During the configuration, the engineer needs to configure the SNMP protocol and USM users in the storage system for receiving and querying system alarms.; D. If certificates and CA certificates are generated on the Syslog server, the engineer does not need to perform any operation in the storage system.

Explanation:

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.
