CIW-NTA Lesson 4 Questions and
Answers Rated A+
Question: What is the primary function of a router in a network?


Answer: ✔✔ A router directs data packets between different networks and manages traffic

within the network to ensure efficient communication and prevent collisions.




Question: How does a switch differ from a hub in network communication?


Answer: ✔✔ A switch sends data only to the specific device it is intended for, while a hub

broadcasts data to all devices on the network, potentially leading to collisions and inefficiency.




Question: What is the purpose of a subnet mask in networking?


Answer: ✔✔ A subnet mask divides an IP address into network and host portions, helping to

determine which part of the IP address identifies the network and which part identifies the

device.




Question: What is the role of the DNS (Domain Name System) in a network?


Answer: ✔✔ DNS translates human-readable domain names (like www.example.com) into IP

addresses that computers use to identify each other on the network.

,Question: What does the acronym DHCP stand for, and what is its function?


Answer: ✔✔ DHCP stands for Dynamic Host Configuration Protocol, and it automatically

assigns IP addresses and other network configuration details to devices on a network.




Question: Explain what a VPN is and its primary use.


Answer: ✔✔ A VPN, or Virtual Private Network, provides a secure, encrypted connection over a

less secure network, such as the Internet, allowing users to access network resources remotely

while protecting their data from unauthorized access.




Question: What is a VLAN and how does it benefit network management?


Answer: ✔✔ A VLAN, or Virtual Local Area Network, segments a physical network into

multiple logical networks, improving security, reducing broadcast traffic, and enhancing network

performance by isolating traffic within each VLAN.




Question: What is the difference between TCP and UDP in terms of data transmission?


Answer: ✔✔ TCP (Transmission Control Protocol) ensures reliable, ordered, and error-checked

delivery of data, while UDP (User Datagram Protocol) provides faster but less reliable data

transmission without error checking or ordering.




2

, Question: How does network address translation (NAT) work and what is its purpose?


Answer: ✔✔ NAT translates private IP addresses within a local network to a public IP address

when communicating with external networks, allowing multiple devices to share a single public

IP address and providing a layer of security.




Question: What is the function of a firewall in network security?


Answer: ✔✔ A firewall monitors and controls incoming and outgoing network traffic based on

predefined security rules, protecting the network from unauthorized access and potential threats.




Question: What is the OSI model and why is it important in networking?


Answer: ✔✔ The OSI (Open Systems Interconnection) model is a conceptual framework that

standardizes the functions of a network into seven layers, helping to understand and troubleshoot

network communication by breaking it into manageable components.




Question: Describe what is meant by network topology and name a common type.


Answer: ✔✔ Network topology refers to the physical or logical arrangement of devices and

connections in a network. A common type is the star topology, where all devices are connected

to a central hub or switch.
