CompTIA A+ Certification Core 1 (220-1101) - WANs and Routers

The video tutorial explains the basics of Ethernet and LAN, highlighting the limitations of scaling LANs beyond a certain number of computers. It introduces the concept of routers as a solution to connect multiple LANs, using logical addressing and IP addresses. The tutorial also provides an example of a home network setup, explaining how devices are assigned unique IP addresses and the role of DHCP in simplifying network configuration.

What is the maximum number of computers that can be connected to a single Ethernet switch according to the standard?

• 24

• 512

• 1024

• 2048

Why is a different addressing system needed when connecting multiple LANs?

• To reduce the cost of networking equipment

• To allow for wireless connections

• To manage traffic between different LANs

• To increase the speed of data transfer

What is the primary function of a router in a network?

• To provide wireless connectivity

• To connect devices within a single LAN

• To increase the number of available ports

• To manage traffic between different LANs

What is the difference between a MAC address and an IP address?

• MAC addresses are logical, IP addresses are physical

• MAC addresses are physical, IP addresses are logical

• Both are logical addresses

• Both are physical addresses

How is a device's logical address typically assigned in a network?

• It is burned into the device at the factory

• It is manually entered by the user

• It is automatically assigned by a DHCP server

• It is determined by the device's location

What role does DHCP play in a home network?

• It provides wireless connectivity

• It assigns IP addresses automatically

• It increases network speed

• It connects multiple LANs

In a typical home network, what is the convention for the router's IP address?

• 192.168.1.1

• 192.168.4.1

• 192.168.0.1

• 192.168.1.100
