Free CTA Telecommunications Network Design & Architecture Questions and Answers

Question 1

What is the primary purpose of a network topology?

Accepted Answer

Defines arrangement and connections of network devices

Answer

Network topology refers to the physical or logical arrangement of elements (links, nodes, etc.) of a communication network. It describes how devices like computers, routers, and switches are interconnected and communicate with each other. Understanding the topology is crucial for designing, troubleshooting, and optimizing network performance and reliability.

Question 2

Which topology features a central connection point?

Accepted Answer

Star topology

Answer

In a star topology, all network devices are connected to a central hub, switch, or server. This central connection point acts as a conduit for all data traffic between devices. While easy to install and manage, a major drawback is that if the central device fails, the entire network segment connected to it goes down.

Question 3

What device connects different networks together?

Accepted Answer

Router

Answer

A router is a networking device that forwards data packets between computer networks. It connects different networks, such as a local area network (LAN) to the internet (WAN), by determining the best path for data to travel. Routers use IP addresses to direct traffic, ensuring data reaches its intended destination across various interconnected networks.

Question 4

Which protocol ensures reliable transmission of data?

Accepted Answer

TCP

Answer

TCP (Transmission Control Protocol) is a core protocol of the internet protocol suite that ensures reliable, ordered, and error-checked delivery of data between applications. It establishes a connection, segments data into packets, reassembles them at the destination, and requests retransmission of any lost packets. This reliability makes it essential for applications like web browsing, email, and file transfer.

Question 5

What is redundancy in network design?

Accepted Answer

Providing backup paths for reliability

Answer

Redundancy in network design involves duplicating critical components or providing alternative paths for data transmission. Its primary purpose is to enhance network reliability and availability by ensuring that if one component or path fails, there is a backup to take over. This prevents single points of failure and minimizes downtime, crucial for mission-critical systems.
