,1. Multiple Choice: Which protocol is used for securely
transferring files between a client and a server on a computer
network?
a) FTP
b) HTTP
c) SFTP
d) SMTP
Correct Answer: c) SFTP
Rationale: SFTP (Secure File Transfer Protocol) is a network
protocol that provides file access, file transfer, and file
management functionalities over any reliable data stream.
2. Fill-in-the-Blank: The ________ layer of the OSI model is
responsible for the delivery of a message from one process to
another.
Correct Answer: Transport
Rationale: The Transport layer ensures complete data transfer.
3. True/False: In computer networks, TCP is more reliable than
UDP.
Correct Answer: True
©2024/2025
, Rationale: TCP (Transmission Control Protocol) is considered
more reliable because it provides error checking and guarantees
delivery of data.
4. Multiple Response: Select all that apply. Which of the
following are characteristics of IPv6?
a) Larger address space
b) Smaller header size compared to IPv4
c) Mandatory IPsec support
d) Backward compatibility with IPv4
Correct Answers: a) Larger address space, c) Mandatory IPsec
support
Rationale: IPv6 has a larger address space and mandatory IPsec
support, but it does not have a smaller header size compared to
IPv4 nor backward compatibility with IPv4.
5. Multiple Choice: What type of network topology is most
resilient to failures?
a) Star
b) Ring
c) Mesh
d) Bus
Correct Answer: c) Mesh
©2024/2025
, Rationale: In a mesh topology, each node is connected to
several other nodes, which allows for the rerouting of data if one
node fails.
6. Fill-in-the-Blank: ________ is a network device that forwards
data packets between computer networks, creating an overlay
internetwork.
Correct Answer: Router
Rationale: A router is used to forward data packets between
computer networks.
7. True/False: UDP guarantees ordered delivery of packets.
Correct Answer: False
Rationale: UDP (User Datagram Protocol) does not guarantee
ordered delivery of packets, unlike TCP.
8. Multiple Response: Which of the following are layers in the
TCP/IP model? (Select all that apply)
a) Application
b) Presentation
c) Internet
d) Network Access
