Question 41
What does the Internet Protocol (IP) do?
a) Assigns unique numbers (IP addresses) to each connected device
b) Encrypts data for secure transmission
c) Manages hardware connections
d) Sends files over the internet
Correct Answer: a) Assigns unique numbers (IP addresses) to each connected device
Explanation: IP is responsible for addressing and routing data packets to ensure they reach their correct destinations across the internet.
Question 42
What does the application layer of TCP/IP do?
a) Manages hardware connections
b) Contains everything that exchanges information and sends files to the transport layer
c) Provides encryption for data
d) Ensures packets are delivered reliably
Correct Answer: b) Contains everything that exchanges information and sends files to the transport layer
Explanation: The application layer facilitates user interactions and data exchange between software applications and the transport layer of the TCP/IP model.
Question 43
What is the purpose of the Secure Shell (SSH) protocol?
a) To transfer files securely
b) For remote access to computers
c) To send email messages
d) To encrypt data packets
Correct Answer: b) For remote access to computers
Explanation: SSH provides a secure method for remote access and management of devices over a network, ensuring encrypted communication.
Question 44
What port number is used by the Simple Mail Transfer Protocol (SMTP)?
a) 21
b) 25
c) 22
d) 23
Correct Answer: b) 25
Explanation: SMTP commonly uses port 25 for sending email messages between servers on the internet.
Question 45
What is the function of File Transfer Protocol (FTP)?
a) To encrypt data during transmission
b) To transfer files between computers over the internet
c) To manage network traffic
d) To provide secure email services
Correct Answer: b) To transfer files between computers over the internet
Explanation: FTP is a standard network protocol used to transfer files between computers across a TCP-based network.
Question 46
What port number does FTP use?
a) 22
b) 23
c) 25
d) 21
Correct Answer: d) 21
Explanation: FTP typically operates over port 21, facilitating file transfer operations between clients and servers.
Question 47
What does the Telnet protocol allow?
a) Secure file transfers
b) Remote access to computers as if they were local terminals
c) Video streaming
d) Data encryption
Correct Answer: b) Remote access to computers as if they were local terminals
Explanation: Telnet enables users to remotely access and control computers over a network as if they were using local terminals.
Question 48
What protocol does ICMP belong to?
a) HTTP
b) FTP
c) TCP/IP
d) SMTP
Correct Answer: c) TCP/IP
Explanation: ICMP (Internet Control Message Protocol) is part of the TCP/IP protocol suite and is used for sending error messages and operational information.
Question 49
What is the purpose of the User Datagram Protocol (UDP)?
a) To provide reliable data delivery with error-checking
b) To send packets quickly with minimal error-checking
c) To manage email communications
d) To establish secure connections
Correct Answer: b) To send packets quickly with minimal error-checking
Explanation: UDP is designed for fast data transmission, sacrificing reliability and error-checking, making it suitable for applications like video streaming and online gaming.
Question 50
What is the function of the Address Resolution Protocol (ARP)?
a) To encrypt data packets
b) To determine the MAC address based on the IP address
c) To manage email routing
d) To monitor network traffic
Correct Answer: b) To determine the MAC address based on the IP address
Explanation: ARP translates IP addresses into MAC addresses, allowing devices to communicate within a local network.
