CCST Networking Fundamentals

Question 1

What does LAN stand for?

Accepted Answer

Local Area Network

Answer

LAN stands for Local Area Network, which is a computer network that interconnects computers within a limited area such as a residence, school, laboratory, university campus, or office building. It allows devices to share resources and communicate with each other efficiently over short distances.

Question 2

What device connects multiple networks together?

Accepted Answer

Router

Answer

A router is a networking device that connects multiple distinct networks, such as a local area network (LAN) to the internet (a wide area network, WAN). Its primary function is to forward data packets between these networks, making intelligent decisions about the best path for data to travel. Switches connect devices within a single network, while routers connect different networks together.

Question 3

What is the function of a switch?

Accepted Answer

Forward data to devices

Answer

A network switch operates at the data link layer (Layer 2) of the OSI model and is designed to efficiently forward data frames to specific devices within the same local area network (LAN). Unlike a hub, which broadcasts data to all connected devices, a switch learns the MAC addresses of connected devices and sends data only to the intended recipient. This targeted forwarding improves network performance and reduces unnecessary traffic.

Question 4

What type of cable is commonly used in Ethernet networks?

Accepted Answer

Twisted pair

Answer

Twisted pair cable, specifically unshielded twisted pair (UTP) and shielded twisted pair (STP), is the most common type of cabling used in modern Ethernet networks. It consists of pairs of insulated wires twisted together to reduce electromagnetic interference and crosstalk. This design allows for reliable data transmission over short to medium distances, making it ideal for connecting computers and network devices within buildings.

Question 5

Which model has 7 layers of networking?

Accepted Answer

OSI model

Answer

The OSI (Open Systems Interconnection) model is a conceptual framework that standardizes the functions of a telecommunication or computing system into seven distinct layers. Each layer performs specific tasks, from the physical transmission of data to application-level services. This layered approach helps in understanding and designing network architectures.
