Question 1

What does network topology refer to?

Accepted Answer

Network layout

Answer

Network topology refers to the physical or logical arrangement of elements (nodes, links, etc.) of a communication network. It describes how devices are interconnected and how data flows between them. The chosen topology significantly influences network performance, reliability, and cost, making it a fundamental design consideration.

Question 2

Which topology offers redundancy but higher cost?

Accepted Answer

Mesh

Answer

A mesh topology offers the highest level of redundancy because every device is connected to every other device, creating multiple pathways for data transmission. While this provides excellent fault tolerance and reliability, ensuring continuous operation even if a link fails, it also incurs the highest cost due to the extensive cabling and numerous connections required.

Question 3

What tool is used to analyze network traffic?

Accepted Answer

Packet sniffer

Answer

A packet sniffer, also known as a network analyzer or protocol analyzer, is a tool used to capture and analyze data packets traveling across a computer network. It allows administrators to monitor network traffic, diagnose issues, and identify potential security threats by examining the content of these packets. This is crucial for network management and cybersecurity.

Question 4

What does QoS stand for?

Accepted Answer

Quality of Service

Answer

QoS stands for Quality of Service, which refers to technologies that manage network traffic to ensure certain applications or data streams receive prioritized bandwidth and performance. This is crucial in telecommunications for services like VoIP and video conferencing, where consistent performance is vital for user experience.

Question 5

Which metric indicates network speed?

Accepted Answer

Bandwidth

Answer

Bandwidth measures the maximum rate at which data can be transferred over a network connection, typically expressed in bits per second (bps). It directly indicates the capacity or 'speed' of a network link, determining how much data can flow through it within a given time. Higher bandwidth generally means faster data transfer.
