Question 23: What is the function of a DHCP server in a network?

To assign dynamic IP addresses to devices

To filter incoming and outgoing traffic

To provide encrypted communications between devices

To route data between different networks

Question 24: Which protocol is used to securely transfer files between computers over a network?

FTP

HTTP

SFTP

DNS

Question 25: What does a MAC filter do in a wireless network?

Encrypts wireless traffic for secure transmission

Assigns IP addresses based on the MAC address

Restricts or allows access based on the MAC address of a device

Amplifies wireless signals for better coverage

Question 26: What does a RAID 1 configuration provide?

Faster read and write speeds

Data redundancy through mirroring

Dynamic IP assignment

VLAN traffic management

Question 27: What is the purpose of a DMZ (Demilitarized Zone) in network security?

To assign dynamic IP addresses

To act as a buffer zone between public and private networks

To encrypt all incoming and outgoing network traffic

To store backup data for redundancy

Question 28: What is the difference between full-duplex and half-duplex communication?

Full-duplex allows communication in both directions simultaneously, while half-duplex only allows communication in one direction at a time

Full-duplex amplifies signals, while half-duplex does not

Full-duplex is used for wireless communication, while half-duplex is used for wired communication

Full-duplex encrypts data, while half-duplex does not

Question 29: What is the primary function of a load balancer in a network?

To amplify weak network signals

To distribute network traffic evenly across multiple servers

To encrypt data transmissions for security

To resolve hostnames to IP addresses

Question 30: What does a VLAN (Virtual Local Area Network) allow you to do?

Encrypt data for secure transmission

Segment a network logically without physical separation

Assign dynamic IP addresses to devices

Amplify network signals over long distances

Question 31: What is the function of the presentation layer in the OSI model?

To route data between networks

To format and encrypt data for application-level communication

To assign IP addresses to devices

To manage physical connections between devices

Question 32: Which type of cable is typically used for long-distance communication in a network?

Twisted-pair cable

Coaxial cable

Fiber-optic cable

USB cable

Question 33: What does the acronym FTP stand for?

File Transfer Protocol

Fast Transmission Process

Fiber Transmission Protocol

Frame Transfer Protocol

Question 34: What is the purpose of a subnet mask in IP addressing?

To encrypt data transmissions

To divide an IP address into network and host portions

To filter traffic based on MAC addresses

To manage VLAN traffic

Question 35: What is a "honey pot" in network security?

A backup system for storing data

A network device used to amplify signals

A decoy system designed to attract and monitor attackers

A method of encrypting sensitive data

Question 36: What is the purpose of a VPN (Virtual Private Network)?

To route data between different networks

To create a secure, encrypted connection over a public network

To assign dynamic IP addresses to devices

To resolve domain names to IP addresses

Question 37: What is the main function of the transport layer in the OSI model?

To manage physical network connections

To ensure reliable data transmission and error correction

To encrypt data for secure communication

To route data packets between different networks

Question 38: What is a multicast address used for in networking?

To send data to multiple recipients simultaneously

To send data to a single recipient

To encrypt network traffic for secure transmission

To route data between different networks

Question 39: What does the acronym IMAP stand for?

Internet Messaging and Access Protocol

Integrated Mail Application Protocol

Internet Mail Access Protocol

Intranet Messaging Application Protocol

Question 40: What is the purpose of a network switch?

To route data between different networks

To filter and forward data based on MAC addresses

To assign dynamic IP addresses to devices

To amplify weak network signals
