Free HCIP-Storage V5.5 Exam H13-624_V5.5 Exam Practice Test

An industry customer has purchased a Huawei OceanStor Pacific 9950 scale-out storage device for service deployment. During an inspection of the device, the location indicator of a main storage disk module is steady yellow. What is the status of the disk module?

• The main storage disk module is being located.
• The main storage disk module is running properly.
• The main storage disk module is powered off.
• The main storage disk module is faulty or about to fail.

When delivering a Huawei OceanStor Pacific storage project, a Huawei engineer vigorously promoted the SmartEncryption feature of scale-out storage to customers. Which of the following statements is false about this feature?

• When the data is read using the DPC or NFS protocol, the SED obtains the identity authenticationkey from the key management server, reads and decrypts the ciphertext data, and then returns the plaintext data to the protocol layer. The protocol layer returns the plaintext data to client applications.
• This feature supports encrypted data write using NFS, CIFS, HDFS, or S3. Data is decrypted and read using NFS, CIFS, HDFS, or S3.
• The file service client can write plaintext data through the NFS/CIFS/DPC protocol.
• Huawei OceanStor Pacific series scale-out storage supports disk encryption. All data delivered by services is stored on self-encrypting disks (SEDs).

A financial customer has purchased a Huawei OceanStor Dorado series storage system for service deployment. To ensure service data reliability, an engineer configures the HyperClone feature on the storage system. Which of the following statements about this feature are false?

• A source LUN and a target LUN form a HyperClone pair, and a source LUN cannot form multiple HyperClone pairs with different target LUNs.
• This feature provides a full copy of the source LUN's data at the synchronization start time. Hosts can read and write the target LUN immediately, without waiting for the copy process to complete.
• This feature synchronizes data from the source LUN to the target LUN and can also restore data from the target LUN to the source LUN.
• There are significant differences between clone blocks and clone file systems. The former is implemented based on the redirect-on-write (ROW) technology, while the latter is implemented based on the copy-on-write (COW) technology.

Fill in blankThe OceanStor Pacific series storage systems support the feature. This feature uses the classic token bucket algorithm to control the traffic upper limit. If local tokens are insufficient, tokens are continuously generated and added to the token bucket based on the OPS and bandwidth upperlimit of the corresponding QoS control object as the rate.

The scale-out storage system supports cabinet-level security. That is, N data blocks and M parity blocks are stored in different cabinets. If M nodes or M disks are faulty, the system can still read and write data without service interruption or data loss. If M cabinets are faulty, services may be interrupted.

• TRUE
• FALSE

Fill in blankIf Huawei scale-out storage software is installed in low level design (LLD) mode, engineers need to use the installation and deployment tool to plan nodes, networks, and clusters and export the configuration file for subsequent installation and deployment.

Routine management on Huawei flash storage systems involves power-on and power-off. Which of the following statements is false about power-on and power-off?

• Before powering on the storage system, you need to ensure that all expansion cables are correctly connected. The storage system may work improperly if the connection mode of expansion cables is adjusted after the storage system is powered on.
• If none of the controller enclosures in the cluster are powered on, you can log in to the BMC system using the external management IP address of the BMC and run the power-on command to power on all the controller enclosures.
• To power on the storage system after an emergency power-off, you need to press the power button on the controller enclosure.
• For Huawei OceanStor Dorado 8000 storage, after a controller enclosure is powered on, its cascaded disk enclosures will be automatically powered on.

Assume a government office purchases several Huawei OceanStor Pacific series storage products. Which statement is false about the hardware and software deployment of the storage products?

• During software deployment, Device Manager must be used to initialize the network of nodes.
• During hardware deployment, SmartKit can be used to install OSs in batches.
• During software deployment, SmartKit can be used to configure clusters, such as disabling Link Layer Discovery Protocol (LLDP) for an OS and enabling the function of Baseboard Management Controller (BMC) mobile customization.
• SmartKit can be used to configure the BMC IP addresses, subnet masks/prefixes, gateways, and
• BMC host names, and to check the firmware, OS, and driver versions.

Huawei OceanStor Pacific series is an intelligent scale-out storage product that supports large-scale scale-out and delivers high reliability. Which of the following statements are false about the product's reliability?

• In terms of data reliability, multiple RAID policies are supported based on the traditional disk-level RAID mode.
• The product adopts Kunpeng processors to integrate functions of multiple chips and effectively improve hardware reliability.
• The product leverages link aggregation to ensure transmission link redundancy and performs link switchover or isolation to ensure service continuity if a link becomes faulty or subhealthy.
• The product uses the multi-copy technology to implement the intra-node RAID function. If a node is faulty, the system reliability is not degraded and even remains higher than that of the EC mechanism.

During routine inspection, engineers find that several faults occur on Huawei all-flash storage and need to rectify the faults. Which of the following is not a basic troubleshooting principle for storage systems?

• Analyze network alarms before NE alarms.
• Analyze general alarms before specific alarms.
• Analyze alarms of higher severities before those of lower severities.
• Analyze external factors before internal factors.
