Q21. Which storage feature improves efficiency by reducing repeated data blocks

1. Mapping
2. Mirroring
3. Deduplication
4. Zoning

Correct Answer: 3. Deduplication

Explanation:

Deduplication improves storage efficiency by identifying repeated data blocks and avoiding unnecessary duplicate copies. When identical data already exists, the storage system can reference the existing copy instead of storing the same information again. This can reduce physical capacity consumption significantly, especially in environments containing similar virtual machines, backups, or repeated user files. Mapping controls how storage resources are presented to hosts. Mirroring creates duplicate copies for protection. Zoning controls communication between devices in a Fibre Channel environment. Deduplication is therefore the correct choice because its main purpose is to eliminate redundant stored information and improve overall capacity utilization.

Q22. Which component connects a server to a Fibre Channel network

1. HBA
2. Fan module
3. Power module
4. Disk tray

Correct Answer: 1. HBA

Explanation:

An HBA connects a host server to a Fibre Channel storage network. It provides the interface required for the server to communicate with Fibre Channel switches and storage systems. The HBA processes storage traffic and allows the operating system to access remote block storage resources. Fan modules provide cooling, power modules supply electrical power, and disk trays physically contain storage drives. None of these performs the host connectivity function of an HBA. In Huawei storage environments, correctly configuring host adapters is important because they form part of the data path between application servers and shared storage resources in the storage network.

Q23. Which storage technique creates an exact duplicate on another disk

1. Compression
2. Tiering
3. Formatting
4. Mirroring

Correct Answer: 4. Mirroring

Explanation:

Mirroring stores identical copies of data on separate disks. When information is written to one disk, the same information is written to its mirror. If one disk fails, the other disk can continue providing access to the data. This improves availability and provides protection from a single disk failure. Compression reduces the size of stored information. Tiering places data on different storage media according to access requirements. Formatting prepares a storage resource for use. Mirroring is the correct answer because its main function is to maintain an exact duplicate of data on another disk for redundancy and continued service availability.

Q24. Which technology provides access to storage through standard IP networks

1. RAID
2. iSCSI
3. SAS
4. Tape

Correct Answer: 2. iSCSI

Explanation:

iSCSI provides block storage communication through standard IP networks. It carries SCSI commands using TCP IP, allowing servers to communicate with remote storage through Ethernet infrastructure. This can reduce deployment cost because organizations can use familiar networking technologies rather than creating a separate Fibre Channel environment. RAID organizes disks for performance or protection. SAS is mainly used for direct storage device connections. Tape is commonly used for backup and archival retention. iSCSI is therefore the correct answer because it specifically enables block storage access through standard IP based networks and is commonly supported by Huawei enterprise storage platforms.

Q25. Which feature controls which host can access a specific LUN

1. LUN mapping
2. Compression
3. Cache
4. Formatting

Correct Answer: 1. LUN mapping

Explanation:

LUN mapping controls which host or host group can access a specific logical storage resource. After a LUN is created, administrators map it to authorized servers so those hosts can detect and use the storage. This prevents unrelated systems from accessing storage resources that are not assigned to them. Compression reduces the amount of capacity used by data. Cache provides temporary high speed storage. Formatting prepares storage for use by an operating system or application. LUN mapping is therefore the correct answer because it directly manages the relationship between a host and the logical block storage resources made available to that host.

Q26. Which measurement describes the amount of data transferred over time

1. Capacity
2. Latency
3. Throughput
4. Temperature

Correct Answer: 3. Throughput

Explanation:

Throughput measures the amount of data transferred by a storage system during a specific period. It is commonly expressed using units such as megabytes or gigabytes per second. High throughput is important for workloads that move large amounts of data, including media processing, backup, and large sequential operations. Capacity describes how much data a system can store. Latency measures how long a request takes to complete. Temperature is a physical operating condition. Throughput is therefore the correct answer because it focuses on data transfer volume over time and is one of the main measurements used when evaluating Huawei storage system performance.

Q27. Which RAID type combines mirroring and striping

1. RAID 0
2. RAID 10
3. RAID 5
4. RAID 6

Correct Answer: 2. RAID 10

Explanation:

RAID 10 combines disk mirroring with striping. Data is mirrored for redundancy and then distributed across multiple disk pairs to improve performance. This design provides strong read and write performance while maintaining protection against disk failures within the mirrored sets. RAID 0 uses striping without redundancy. RAID 5 uses distributed parity and can normally tolerate one disk failure. RAID 6 uses additional parity and can tolerate two disk failures. RAID 10 is therefore the correct answer because it directly combines the protection benefits of mirroring with the performance benefits of striping and is useful for demanding enterprise storage workloads.

Q28. Which feature preserves data before a major application change

1. Zoning
2. Multipathing
3. Compression
4. Snapshot

Correct Answer: 4. Snapshot

Explanation:

A snapshot preserves the state of data at a specific point in time and can be created before an important application or system change. If the change causes unexpected problems or data loss, administrators may use the snapshot to restore an earlier state quickly. Zoning manages communication within a Fibre Channel network. Multipathing maintains multiple paths between hosts and storage. Compression reduces storage capacity requirements. A snapshot is therefore the correct answer because it provides a fast point in time protection method that is useful before maintenance, upgrades, configuration changes, or other activities that might affect important application data.

Q29. Which storage protocol is mainly used by Unix systems for shared files

1. SMTP
2. DNS
3. NFS
4. FCP

Correct Answer: 3. NFS

Explanation:

NFS is widely used in Unix and Linux environments to provide shared file access across a network. It allows users and applications to access remote directories as though they were part of the local file system. SMTP is used to transfer email messages. DNS resolves host names into network addresses. FCP carries storage commands across Fibre Channel networks and is mainly associated with block storage. NFS is therefore the correct answer because it is specifically designed for network file sharing and is commonly used when Huawei storage systems provide centralized file services to Unix and Linux servers and client environments.

Q30. Which storage device is mainly used for long term archival data

1. Tape
2. Cache
3. RAM
4. HBA

Correct Answer: 1. Tape

Explanation:

Tape is commonly used for long term archival data because it provides high capacity and relatively low cost per unit of stored information. Tape cartridges can be stored offline, which can also provide protection from certain online threats and system failures. Cache and RAM are temporary memory technologies designed for fast data access rather than long term retention. An HBA is a host adapter used for storage network connectivity and does not store archival data. Tape is therefore the correct answer because it is designed for backup and long term information retention, especially when large amounts of inactive data must be stored economically for extended periods.

Q31. Which technology allows a server to use several storage paths

1. Replication
2. Multipathing
3. Deduplication
4. Cloning

Correct Answer: 2. Multipathing

Explanation:

Multipathing allows a server to maintain several communication paths to a storage system. If one path becomes unavailable because of a cable, port, switch, or adapter failure, another path can continue carrying storage traffic. This improves availability and can also support traffic balancing depending on the environment. Replication creates another data copy. Deduplication reduces repeated stored information. Cloning creates a separate usable copy of data. Multipathing is therefore the correct answer because it specifically provides multiple routes between the host and storage. Huawei storage deployments commonly use redundant paths to reduce the risk of connectivity failures affecting critical applications.

Q32. Which storage feature creates a separate usable copy for testing

1. Cache
2. Encryption
3. Pooling
4. Clone

Correct Answer: 4. Clone

Explanation:

A clone creates a separate usable copy of selected storage data. This makes cloning useful for testing, development, reporting, or other activities where a separate copy of production information is required. Users can work with the cloned data without directly modifying the original source. Cache stores temporary information for faster access. Encryption protects confidentiality. Pooling combines physical storage resources into a logical collection. A clone is therefore the correct answer because its purpose is to provide an independent or separately usable copy of existing data. Huawei storage systems can use cloning to simplify development and test environments while protecting production information.

Q33. Which feature assigns storage capacity only when data is actually written

1. Thin provisioning
2. RAID
3. Mirroring
4. Zoning

Correct Answer: 1. Thin provisioning

Explanation:

Thin provisioning allows logical storage capacity to be presented to a host while physical capacity is consumed only as data is written. This can improve utilization because storage does not need to be fully reserved at the time of initial allocation. Administrators can therefore assign flexible capacity while using shared physical resources more efficiently. RAID organizes disks for protection or performance. Mirroring maintains duplicate copies. Zoning controls Fibre Channel communication. Thin provisioning is the correct answer because it directly supports capacity allocation according to actual consumption. Huawei storage systems use thin provisioning to simplify expansion and improve overall physical storage utilization.

Q34. Which RAID level commonly uses one set of distributed parity

1. RAID 0
2. RAID 1
3. RAID 10
4. RAID 5

Correct Answer: 4. RAID 5

Explanation:

RAID 5 distributes data and one set of parity information across multiple disks. The parity information allows the system to reconstruct data if one disk fails. This provides a useful balance between protection, usable capacity, and performance. RAID 0 provides striping without fault tolerance. RAID 1 uses disk mirroring. RAID 10 combines mirroring with striping. RAID 5 is therefore the correct answer because its defining protection mechanism is one set of distributed parity. In Huawei storage planning, selecting the correct RAID level is important because each RAID type provides different capacity, protection, and performance characteristics for application workloads.

Q35. Which component contains the physical drives in a storage system

1. Controller
2. Disk enclosure
3. HBA
4. Fibre switch

Correct Answer: 2. Disk enclosure

Explanation:

A disk enclosure contains physical storage drives such as SSDs or hard disks. It provides the physical slots, connections, power, and supporting infrastructure needed to install and operate those drives as part of the storage system. A controller manages storage services and input and output processing. An HBA connects a server to a storage network. A Fibre Channel switch connects devices within a Fibre Channel environment. The disk enclosure is therefore the correct answer because its primary role is to house physical drives. Huawei storage systems can use multiple disk enclosures to increase available capacity and support larger enterprise storage configurations.

Q36. Which feature protects information by making stored data unreadable

1. Mapping
2. Pooling
3. Encryption
4. Tiering

Correct Answer: 3. Encryption

Explanation:

Encryption protects stored information by converting readable data into an unreadable form. Authorized users or systems can recover the original data only when the appropriate cryptographic key is available. This helps protect sensitive information if storage media is lost, stolen, or accessed without authorization. Mapping controls which hosts can see storage resources. Pooling combines physical capacity into logical groups. Tiering moves data between different performance levels. Encryption is therefore the correct answer because its main purpose is to protect data confidentiality. Huawei storage security features may use encryption to help organizations protect important information and meet security or compliance requirements.

Q37. Which network control limits communication between Fibre Channel devices

1. Compression
2. Caching
3. Formatting
4. Zoning

Correct Answer: 4. Zoning

Explanation:

Zoning controls which devices in a Fibre Channel network are allowed to communicate with one another. It is commonly configured on Fibre Channel switches and can limit communication between specific hosts and storage ports. This improves organization, security, and stability within the storage network. Compression reduces data size. Caching improves performance by temporarily storing frequently used information. Formatting prepares storage for use. Zoning is therefore the correct answer because it specifically controls communication among Fibre Channel devices. In Huawei storage network deployments, proper zoning helps ensure that servers connect only to the intended storage resources and reduces unnecessary visibility between unrelated devices.

Q38. Which storage feature automatically places active data on faster media

1. Replication
2. Tiering
3. Snapshot
4. Mapping

Correct Answer: 2. Tiering

Explanation:

Tiering places data on different types of storage media according to access frequency or performance requirements. Frequently accessed information can be moved to faster media such as SSDs, while less active data can remain on lower cost storage. This can improve performance while controlling capacity costs. Replication maintains another copy of data. Snapshots preserve point in time data states. Mapping presents storage resources to hosts. Tiering is therefore the correct answer because it focuses on selecting the most appropriate storage media for different data according to activity. Huawei storage systems can use tiering to improve resource utilization and application performance.

Q39. Which technology groups multiple disks into a logical storage resource

1. Storage pool
2. SMTP
3. DNS
4. Firewall

Correct Answer: 1. Storage pool

Explanation:

A storage pool combines capacity from multiple physical disks into a logical resource that administrators can manage and allocate more easily. Logical storage such as LUNs can then be created from the available capacity within the pool. This simplifies administration and supports flexible resource allocation. SMTP is an email protocol, DNS provides name resolution, and a firewall controls network traffic. These technologies do not combine physical disks into logical storage capacity. A storage pool is therefore the correct answer. Huawei storage systems use storage pools to organize physical resources and provide a foundation for features such as thin provisioning and logical storage allocation.

Q40. Which metric measures how long a storage request takes to complete

1. Capacity
2. Bandwidth
3. Latency
4. Disk count

Correct Answer: 3. Latency

Explanation:

Latency measures the time required for a storage request to complete. Lower latency generally means that applications receive responses more quickly, which is especially important for databases and other transaction focused workloads. Capacity describes how much information a system can store. Bandwidth describes how much data can be transferred during a period. Disk count simply indicates the number of physical drives and does not directly measure request response time. Latency is therefore the correct answer because it represents the delay experienced by storage operations. Huawei storage performance analysis commonly evaluates latency together with throughput and IOPS to understand workload behavior and identify performance issues.
