Q61. Which protocol provides file sharing mainly for Windows clients

1. NFS
2. SMB
3. FCP
4. iSCSI

Correct Answer: 2. SMB

Explanation:

SMB is a network file sharing protocol commonly used by Windows clients and servers. It allows users and applications to access shared files and folders across an Ethernet network. Enterprise storage systems can provide SMB services so multiple Windows systems can use centralized file storage. NFS is more commonly associated with Linux and Unix environments. FCP provides block storage communication over Fibre Channel networks. iSCSI carries block storage traffic over IP networks. SMB is therefore the correct answer because it specifically provides file level access and is widely used for shared storage resources in Microsoft Windows based enterprise environments.

Q62. Which backup method copies only data changed since the last backup of any type

1. Full backup
2. Mirror backup
3. Archive backup
4. Incremental backup

Correct Answer: 4. Incremental backup

Explanation:

An incremental backup copies data that has changed since the most recent backup, whether that previous backup was full or incremental. This reduces the amount of information transferred and generally requires less backup time and storage capacity than repeatedly performing full backups. During recovery, however, the latest full backup and the required incremental backups may need to be combined. A full backup copies all selected information. Mirror and archive approaches serve different purposes and do not describe this change tracking method. Incremental backup is therefore the correct answer because it captures only newly created or modified data since the previous backup operation.

Q63. Which device provides physical storage capacity inside a disk enclosure

1. Drive
2. Controller
3. HBA
4. Switch

Correct Answer: 1. Drive

Explanation:

A drive provides the actual physical media used to store data inside a disk enclosure. Depending on the storage platform and workload, the drive may use flash memory or magnetic disk technology. Multiple drives can be organized into storage pools or RAID groups to provide logical capacity and protection. A controller processes storage input and output operations. An HBA connects a host to a storage network. A switch connects multiple storage network devices. The drive is therefore the correct answer because it contains the physical storage media where application information and other persistent data are ultimately retained within the storage system.

Q64. Which backup type copies all selected data during every backup operation

1. Incremental backup
2. Differential backup
3. Full backup
4. Snapshot backup

Correct Answer: 3. Full backup

Explanation:

A full backup copies all selected data each time the backup operation is performed. It provides a complete backup set that can simplify recovery because the required information is available from one full copy. However, full backups normally require more time, network bandwidth, and backup capacity than incremental approaches. Incremental backups copy only changes since the previous backup. Differential backups normally copy changes since the most recent full backup. Snapshot based protection preserves a point in time state and may operate differently from traditional backup. Full backup is therefore the correct answer because every selected item is copied during each backup operation.

Q65. Which Fibre Channel topology allows devices to communicate through a switch fabric

1. Direct attach
2. Switched fabric
3. Local loop only
4. Serial link

Correct Answer: 2. Switched fabric

Explanation:

A switched fabric connects Fibre Channel hosts and storage devices through one or more Fibre Channel switches. This architecture provides scalable connectivity because multiple servers and storage ports can communicate through the fabric. Administrators can also use zoning to control which devices are permitted to communicate. Direct attachment connects devices without using a shared switching fabric. Other listed choices do not describe the normal enterprise Fibre Channel switched architecture. Switched fabric is therefore the correct answer because it enables many devices to participate in a Fibre Channel storage network while providing flexible connectivity, centralized management, and redundant path design for enterprise storage systems.

Q66. Which backup type copies changes made since the most recent full backup

1. Differential backup
2. Incremental backup
3. Mirror backup
4. Tape clone

Correct Answer: 1. Differential backup

Explanation:

A differential backup copies data changed since the most recent full backup. Each new differential backup therefore includes all changes made after that full backup, even if earlier differential backups have already captured some of those changes. This can simplify restoration because recovery generally requires the full backup and the latest differential backup. Incremental backup usually captures only changes since the immediately preceding backup. Mirror and tape clone do not describe this specific change tracking method. Differential backup is therefore the correct answer because its reference point remains the most recent full backup until another full backup is created.

Q67. Which component converts host storage commands into Fibre Channel traffic

1. Disk shelf
2. Power supply
3. Cache module
4. HBA

Correct Answer: 4. HBA

Explanation:

An HBA provides the host interface required for Fibre Channel storage communication. It allows a server to send storage commands through a Fibre Channel network and communicate with shared block storage systems. The HBA handles functions associated with the storage connection and works with host drivers and the Fibre Channel infrastructure. A disk shelf houses physical drives. A power supply provides electrical power. A cache module supports temporary high speed data storage. The HBA is therefore the correct answer because it is the host side component responsible for connecting a server to a Fibre Channel network and carrying storage communication to remote storage resources.

Q68. Which storage protection method keeps backup media disconnected from production systems

1. Online replication
2. Cache protection
3. Offline backup
4. Thin provisioning

Correct Answer: 3. Offline backup

Explanation:

An offline backup keeps backup data or media disconnected from normal production access when it is not being used. This can provide additional protection against threats that affect online systems because the backup cannot be modified directly through the production network while disconnected. Tape media is one common example of technology that can support offline protection. Online replication keeps another data copy but usually remains connected. Cache protection safeguards temporary write information. Thin provisioning improves storage capacity utilization. Offline backup is therefore the correct answer because physical or logical separation from production systems can reduce exposure to certain failures and malicious activity.

Q69. Which term describes a Fibre Channel network made of switches and connected devices

1. Fabric
2. Pool
3. Volume
4. Cluster

Correct Answer: 1. Fabric

Explanation:

A Fibre Channel fabric is the network formed by Fibre Channel switches and the devices connected through them. Hosts and storage systems communicate across this fabric using Fibre Channel protocols. A fabric can include redundant switches and paths to improve availability. Zoning can also be configured within the fabric to control communication between devices. A storage pool groups capacity, a volume represents logical storage, and a cluster generally refers to multiple systems working together. Fabric is therefore the correct answer because it specifically describes the Fibre Channel network infrastructure that provides connectivity among servers, switches, and storage ports in an enterprise storage environment.

Q70. Which function verifies whether stored backup data can be restored successfully

1. Compression
2. Mapping
3. Tiering
4. Recovery testing

Correct Answer: 4. Recovery testing

Explanation:

Recovery testing verifies that backup data can actually be used to restore systems, applications, or files successfully. Creating backups alone does not guarantee that recovery will work when a real failure occurs. Regular testing can identify damaged backup sets, missing dependencies, configuration issues, or procedures that require improvement. Compression reduces the space required for stored information. Mapping presents storage resources to hosts. Tiering moves data between different classes of storage media. Recovery testing is therefore the correct answer because it confirms the practical usability of backup and recovery processes and helps organizations prepare for actual data loss or service interruption events.

Q71. Which technology combines several network links to improve availability and bandwidth

1. Encryption
2. Link aggregation
3. Snapshot
4. Deduplication

Correct Answer: 2. Link aggregation

Explanation:

Link aggregation combines multiple physical network links into one logical connection. This can increase available bandwidth and provide additional resilience because communication may continue through remaining links if one physical connection fails. It is commonly used in Ethernet environments where storage systems and servers require reliable high capacity connectivity. Encryption protects data confidentiality. Snapshots preserve point in time data states. Deduplication reduces repeated stored information. Link aggregation is therefore the correct answer because it specifically joins multiple network connections to improve both communication capacity and availability. Proper configuration can help reduce the effect of individual Ethernet link failures on storage services.

Q72. Which storage resource is presented to applications in a file system as a directory structure

1. Fibre port
2. Disk domain
3. File system
4. HBA

Correct Answer: 3. File system

Explanation:

A file system organizes stored information into files and directories so users and applications can access data through a structured hierarchy. File storage systems can present file systems using protocols such as NFS or SMB. A Fibre port provides connectivity within a Fibre Channel environment. A disk domain groups physical storage resources. An HBA connects a server to a storage network. File system is therefore the correct answer because it provides the logical structure used to organize and manage files and folders. In enterprise storage environments, file systems make shared storage easier for users and applications to access without managing raw storage blocks directly.

Q73. Which technology provides direct high speed access to flash storage using a modern command set

1. Tape
2. FTP
3. SMB
4. NVMe

Correct Answer: 4. NVMe

Explanation:

NVMe is a storage protocol designed for high performance access to flash based storage. It uses a modern command structure that can support many queues and large numbers of commands, helping reduce overhead compared with older storage protocols designed for mechanical disks. NVMe is widely associated with SSD technology and performance sensitive applications. Tape is designed mainly for backup and archival storage. FTP transfers files across networks. SMB provides shared file access. NVMe is therefore the correct answer because it was specifically designed to take advantage of the low latency and parallel processing capabilities available from modern flash storage devices.

Q74. Which term describes a copy of data kept at another geographic location

1. Local cache
2. Remote copy
3. Disk stripe
4. Host mapping

Correct Answer: 2. Remote copy

Explanation:

A remote copy is an additional data copy stored at another geographic location. Keeping data at a separate site helps protect important information from events that could affect the primary location, such as facility failures or other major disruptions. Remote copies are commonly created using replication technologies and are important components of disaster recovery plans. Local cache stores temporary information close to the active system. Disk striping distributes data across disks. Host mapping controls access to logical storage. Remote copy is therefore the correct answer because the copy resides away from the primary site and provides geographic separation for data protection and recovery.

Q75. Which component distributes Fibre Channel traffic between connected ports

1. Fibre Channel switch
2. Disk
3. Cache
4. Tape drive

Correct Answer: 1. Fibre Channel switch

Explanation:

A Fibre Channel switch forwards storage traffic between connected Fibre Channel ports. Servers, storage systems, and other compatible devices connect to switch ports and communicate through the resulting fabric. Fibre Channel switches can also provide functions such as zoning to control which devices are permitted to communicate. A disk stores data, cache holds temporary information for performance, and a tape drive provides backup or archive storage. The Fibre Channel switch is therefore the correct answer because it is the network device responsible for connecting multiple Fibre Channel endpoints and directing storage traffic between hosts and storage systems in a switched storage network.

Q76. Which process restores data from a protected copy after data loss

1. Allocation
2. Formatting
3. Recovery
4. Zoning

Correct Answer: 3. Recovery

Explanation:

Recovery is the process of restoring data or services from a protected copy after accidental deletion, corruption, hardware failure, or another disruptive event. Recovery may use backups, snapshots, replication copies, or other protection mechanisms depending on the situation. Allocation assigns storage capacity to workloads. Formatting prepares storage resources for use. Zoning controls communication in a Fibre Channel network. Recovery is therefore the correct answer because it describes returning lost or unavailable data to a usable state. Effective recovery procedures are an important part of enterprise storage management because data protection has limited value if protected information cannot be restored successfully.

Q77. Which network type is commonly used to carry NAS file traffic

1. Tape network
2. Ethernet
3. Serial console
4. Fibre backend only

Correct Answer: 2. Ethernet

Explanation:

NAS file services commonly use Ethernet networks to deliver shared file access to clients and servers. Protocols such as NFS and SMB operate over IP based networks and are normally transported through Ethernet infrastructure. This makes NAS easy to integrate with existing enterprise networks. Tape networks are not used for general NAS file access. A serial console is mainly intended for device administration. Fibre backend connections may exist inside storage systems but do not represent the typical client network used for NAS file traffic. Ethernet is therefore the correct answer because it provides the standard network foundation for most modern NAS environments.

Q78. Which technology allows storage services to continue when one controller fails

1. Compression
2. Deduplication
3. Controller redundancy
4. File sharing

Correct Answer: 3. Controller redundancy

Explanation:

Controller redundancy uses multiple storage controllers so another controller can continue providing services if one controller becomes unavailable. This reduces the risk that a single controller failure will interrupt access to application data. Enterprise storage platforms commonly combine redundant controllers with redundant power supplies, network paths, and other components to improve overall availability. Compression reduces the amount of capacity required by data. Deduplication removes duplicate data. File sharing provides access to files through network protocols. Controller redundancy is therefore the correct answer because it directly addresses controller failure and helps maintain storage service continuity during hardware faults or planned maintenance activities.

Q79. Which method protects data by keeping multiple complete copies at separate locations

1. Striping
2. Caching
3. Compression
4. Replication

Correct Answer: 4. Replication

Explanation:

Replication protects data by maintaining an additional copy on another storage system or at another location. Depending on the design, replicated copies may be maintained synchronously or asynchronously. The additional copy can support disaster recovery, business continuity, migration, and planned maintenance. Striping distributes data across disks for performance. Caching temporarily stores frequently accessed information. Compression reduces data size. Replication is therefore the correct answer because its purpose is to maintain another usable data copy separate from the original storage resource. Geographic replication can provide additional protection when the primary site experiences a major failure or becomes temporarily unavailable.

Q80. Which storage concept combines resources from many disks for centralized capacity management

1. Storage pooling
2. Port zoning
3. Cache hit
4. Host login

Correct Answer: 1. Storage pooling

Explanation:

Storage pooling combines capacity from multiple physical disks into a logical resource that can be managed centrally. Administrators can create logical storage resources from the pool without managing each physical disk individually. This simplifies provisioning, capacity expansion, and resource utilization. Storage pools can also support technologies such as thin provisioning and other efficiency features. Port zoning controls communication in Fibre Channel networks. Cache hit describes a successful request served from cache. Host login refers to a host establishing access to a storage network. Storage pooling is therefore the correct answer because it consolidates physical disk capacity into a flexible logical resource for management.
