a) Higher storage capacity
b) Faster data access speeds
c) Lower cost
d) Greater durability

Correct Answer: b) Faster data access speeds

Explanation: SSDs utilize flash memory to provide significantly faster data access times compared to traditional HDDs, which rely on spinning disks.

Question 03

What type of memory is known for its volatility?

a) ROM
b) EEPROM
c) RAM
d) Flash memory

Correct Answer: c) RAM

Explanation: RAM (Random Access Memory) is volatile memory, meaning it loses its contents when power is turned off, unlike non-volatile memory types like ROM or flash memory.

Question 04

What does the term “emulator” refer to in computing?

a) A type of virus
b) Software that mimics another system
c) A hardware device
d) A network protocol

Correct Answer: b) Software that mimics another system

Explanation: An emulator allows one computer system to behave like another, enabling software from one platform to run on a different system.

Question 05

What does “network topology” describe?

a) The physical or logical arrangement of nodes in a network
b) The security protocols used in a network
c) The speed of data transmission
d) The type of hardware used in a network

Correct Answer: a) The physical or logical arrangement of nodes in a network

Explanation: Network topology refers to how different nodes in a network are connected and how data is transmitted between them.

Question 06

What is the primary purpose of a Domain Name System (DNS)?

a) To store web pages
b) To manage user accounts
c) To translate domain names into IP addresses
d) To secure network traffic

Correct Answer: c) To translate domain names into IP addresses

Explanation: DNS translates user-friendly domain names into machine-readable IP addresses, enabling browsers to locate resources on the internet.

Question 07

What is the difference between public and private clouds?

a) Public clouds are less secure than private clouds
b) Private clouds are only available to a single organization, while public clouds are available to everyone
c) Public clouds have higher costs than private clouds
d) There is no difference

Correct Answer: b) Private clouds are only available to a single organization, while public clouds are available to everyone

Explanation: Private clouds are tailored to a single organization, providing enhanced security and control, while public clouds offer services to the general public.

Question 08

What is an example of a software-defined network (SDN)?

a) A traditional network with fixed routers
b) A network managed by software applications rather than hardware devices
c) A hardware-based network
d) A network with no centralized control

Correct Answer: b) A network managed by software applications rather than hardware devices

Explanation: SDN separates the control plane from the data plane, allowing network management through software applications for greater flexibility and efficiency.

Question 09

What is the primary role of an access point in a wireless network?

a) To connect wired devices
b) To extend the range of a wireless network
c) To encrypt data
d) To manage network traffic

Correct Answer: b) To extend the range of a wireless network

Explanation: Access points allow wireless devices to connect to a wired network and extend the coverage area of the wireless signal.

Question 10

What type of storage uses magnetic disks to store data?

a) Solid-state drive
b) Optical drive
c) Hard disk drive
d) Flash drive

Correct Answer: c) Hard disk drive

Explanation: Hard disk drives (HDDs) store data on rotating magnetic disks and are commonly used for larger data storage needs.

Question 11

What is the primary function of error-correcting code (ECC) memory?

a) To increase data transfer speeds
b) To detect and correct memory errors
c) To provide data encryption
d) To reduce power consumption

Correct Answer: b) To detect and correct memory errors

Explanation: ECC memory includes error detection and correction capabilities, ensuring data integrity in critical computing environments.

Question 12

What is a common feature of RAID configurations?

a) They only use one disk
b) They enhance performance and/or provide redundancy
c) They require expensive hardware
d) They are not used in enterprise environments

Correct Answer: b) They enhance performance and/or provide redundancy

Explanation: RAID configurations can improve data access speeds and provide data protection through redundancy, depending on the RAID level used.

Question 13

What does the term “cloud storage” refer to?

a) Data stored on local hard drives
b) Data stored on remote servers accessed via the internet
c) Data stored on optical discs
d) Data stored on USB drives

Correct Answer: b) Data stored on remote servers accessed via the internet

Explanation: Cloud storage allows users to save data on remote servers, enabling access from anywhere with an internet connection.

Question 14

What is a primary benefit of using virtualization technology?

a) It eliminates the need for physical servers
b) It allows multiple operating systems to run on a single physical machine
c) It increases the cost of hardware
d) It requires more physical space

Correct Answer: b) It allows multiple operating systems to run on a single physical machine

Explanation: Virtualization enables resource optimization by allowing multiple virtual machines to share the same physical hardware.

Question 15

What is the primary advantage of using a hybrid cloud model?

a) Reduced costs
b) Flexibility to move data and applications between private and public clouds
c) Increased security
d) Improved performance

Correct Answer: b) Flexibility to move data and applications between private and public clouds

Explanation: A hybrid cloud model provides the flexibility to leverage both private and public cloud resources, allowing organizations to optimize their infrastructure.

Question 16

What is the main function of an intrusion detection system (IDS)?

a) To prevent unauthorized access
b) To monitor network traffic for suspicious activity
c) To encrypt sensitive data
d) To manage user authentication

Correct Answer: b) To monitor network traffic for suspicious activity

Explanation: IDS solutions analyze network traffic for potential security breaches and alert administrators to any detected threats.

Question 17

What does the term “latency” refer to in networking?

a) The speed of data transfer
b) The time taken for data to travel from source to destination
c) The amount of data that can be transferred at once
d) The encryption level of data

Correct Answer: b) The time taken for data to travel from source to destination

Explanation: Latency measures the delay before a transfer of data begins following an instruction for its transfer, impacting overall network performance.

Question 18

What is the purpose of data migration?

a) To create backup copies of data
b) To move data between storage types, formats, or systems
