Question 41
What does an access point do in a wireless network?
a) Connects wired devices to the network
b) Extends the range of a wireless network
c) Provides encryption for data transmission
d) Monitors network traffic
Correct Answer: b) Extends the range of a wireless network
Explanation: An access point enables wireless devices to connect to a wired network, extending the overall coverage area of the network.
Question 42
What is the main characteristic of a thick client?
a) Minimal processing capabilities
b) All processing is done on a server
c) It can operate independently of a server
d) It requires constant network connectivity
Correct Answer: c) It can operate independently of a server
Explanation: Thick clients perform the majority of processing on the client side, relying less on a server compared to thin clients.
Question 43
What is the role of a network interface card (NIC)?
a) To provide power to the network
b) To connect a computer to a network
c) To manage data storage
d) To serve as a firewall
Correct Answer: b) To connect a computer to a network
Explanation: A NIC enables a computer to connect to a network, allowing it to communicate with other devices and access resources.
Question 44
What is the primary function of a repeater?
a) To block unauthorized access
b) To amplify and retransmit signals over long distances
c) To filter traffic between network segments
d) To encrypt data
Correct Answer: b) To amplify and retransmit signals over long distances
Explanation: Repeaters extend the range of a network by boosting signals, ensuring data can travel farther without degradation.
Question 45
What is a typical use case for RAID 10?
a) To maximize storage capacity
b) To provide high availability with data redundancy
c) To enhance performance without redundancy
d) To simplify backup processes
Correct Answer: b) To provide high availability with data redundancy
Explanation: RAID 10 combines mirroring and striping, offering both improved performance and fault tolerance, making it suitable for critical applications.
Question 46
What is an important feature of solid-state drives (SSDs)?
a) They have moving parts
b) They store data on spinning disks
c) They use flash memory and have no moving parts
d) They require more power than traditional hard drives
Correct Answer: c) They use flash memory and have no moving parts
Explanation: SSDs are faster and more durable than traditional hard drives because they have no moving components, leading to quicker data access.
Question 47
What is wear leveling in SSDs?
a) A technique to optimize read speeds
b) A method to ensure data is evenly distributed across memory blocks
c) A way to compress data
d) A method of data encryption
Correct Answer: b) A method to ensure data is evenly distributed across memory blocks
Explanation: Wear leveling prolongs the lifespan of SSDs by preventing specific memory blocks from being overused while others remain underused.
Question 48
What does TRIM do in the context of SSDs?
a) It compresses data for storage
b) It helps the SSD manage unused data blocks to improve performance
c) It encrypts data for security
d) It transfers data to external storage
Correct Answer: b) It helps the SSD manage unused data blocks to improve performance
Explanation: TRIM informs the SSD which data blocks are no longer in use, allowing for more efficient data management and maintaining performance.
Question 49
What is a benefit of using optical drives?
a) They are faster than SSDs
b) They provide permanent storage for data
c) They are primarily used for archiving and distribution
d) They have larger capacities than HDDs
Correct Answer: c) They are primarily used for archiving and distribution
Explanation: Optical drives use lasers to read and write data on discs, making them suitable for data archiving and software distribution.
Question 50
What is the purpose of a load balancer in a cloud environment?
a) To provide data backup
b) To manage user permissions
c) To distribute workloads efficiently across multiple resources
d) To enhance security measures
Correct Answer: c) To distribute workloads efficiently across multiple resources
Explanation: Load balancers optimize resource utilization and enhance application availability by evenly distributing incoming traffic across multiple servers.
