Q31. Which of the following is an example of near-line storage?
a) Magnetic tape library
b) Hard disk drive
c) SSD
d) CD-ROM
Show Answer
Correct Answer: a) Magnetic tape library
Explanation: Near-line storage is a type of data storage that falls between online and offline storage in terms of accessibility. An example of near-line storage is a magnetic tape library, which stores data on magnetic tapes that can be automatically retrieved and read to disk, but with some delay compared to online storage.
Q32. Which of the following is a type of Disk Array?
a) RAID (Redundant Array of Independent Disks)
b) CD-ROM Jukebox
c) Tape library
d) RAM disk
Show Answer
Correct Answer: a) RAID (Redundant Array of Independent Disks)
Explanation: RAID (Redundant Array of Independent Disks) is a type of Disk Array that uses multiple disk drives to increase storage capacity and improve performance. RAID systems use techniques such as data striping and redundancy to distribute data across multiple drives, which can improve access times and protect against data loss due to drive failures.
Q33. What is the main purpose of data backup?
a) To increase storage capacity
b) To protect against data loss
c) To improve data access speed
d) To reduce storage costs
Show Answer
Correct Answer: b) To protect against data loss
Explanation: The main purpose of data backup is to protect against data loss. Data backup involves creating copies of data that can be used to restore the original data in case of data corruption, hardware failure, or other data loss events.
Q34. What is the primary advantage of using near-line storage over online storage?
a) Faster access times
b) Higher storage capacity
c) Lower cost per unit of storage
d) Increased reliability
Show Answer
Correct Answer: c) Lower cost per unit of storage
Explanation: The primary advantage of using near-line storage over online storage is its lower cost per unit of storage. Near-line storage devices, such as tape libraries, typically provide a cost-effective solution for storing large amounts of data that is not frequently accessed. While near-line storage requires some delay to access the data, it is more affordable than online storage solutions like SSDs or HDDs.
Q35. Which of the following is an example of offline storage?
a) Hard disk drive
b) SSD
c) Magnetic tape
d) RAM
Show Answer
Correct Answer: c) Magnetic tape
Explanation: Offline storage is a type of data storage that requires manual intervention to access the data. An example of offline storage is magnetic tape, which must be physically loaded into a tape drive before the data can be accessed.
Q36. What is the main advantage of hierarchical storage systems (HSS) over traditional storage systems?
a) Faster data access
b) Lower cost per unit of storage
c) Greater storage capacity
d) Better data security
Show Answer
Correct Answer: b) Lower cost per unit of storage
Explanation: The main advantage of hierarchical storage systems (HSS) over traditional storage systems is the lower cost per unit of storage. HSS automatically moves data between high-cost, high-performance storage devices and low-cost, low-performance storage devices based on how frequently the data is accessed, optimizing storage costs.
Q37. Which of the following is a type of memory storage device?
a) Magnetic tape
b) Hard disk drive
c) RAM
d) Optical disk
Show Answer
Correct Answer: c) RAM
Explanation: A memory storage device is a type of storage device that stores data temporarily for quick access by the computer’s processor. An example of a memory storage device is random access memory (RAM), which stores data that is currently being used or processed by the computer.
Q38. What is the main disadvantage of optical disk storage compared to magnetic disk storage?
a) Lower data transfer rate
b) Higher cost
c) Smaller storage capacity
d) Greater susceptibility to damage
Show Answer
Correct Answer: a) Lower data transfer rate
Explanation: The main disadvantage of optical disk storage compared to magnetic disk storage is the lower data transfer rate. Optical disks use laser technology to read and write data, which is generally slower than the magnetic technology used in magnetic disks.
Q39. What is the primary purpose of off-line storage?
a) To increase storage capacity
b) To improve performance
c) To protect against data loss
d) To provide long-term data storage and backup
Show Answer
Correct Answer: d) To provide long-term data storage and backup
Explanation: The primary purpose of off-line storage is to provide long-term data storage and backup. Off-line storage devices, such as magnetic tapes, are not immediately accessible and require manual intervention to retrieve the storage media from a storage location. This makes them suitable for long-term data storage and backup purposes, as they provide a cost-effective solution for storing large amounts of data that is not frequently accessed.
Q40. What is the main advantage of solid-state drives (SSDs) over hard disk drives (HDDs)?
a) Larger storage capacity
b) Faster data access
c) Lower cost
d) Longer lifespan
Show Answer
Correct Answer: b) Faster data access
Explanation: The main advantage of solid-state drives (SSDs) over hard disk drives (HDDs) is faster data access. SSDs use flash memory to store data, which allows for quicker data retrieval and write times compared to the spinning magnetic disks used in HDDs.
