World of Computer Networking Your CCNA start - Hosts in the Same Network - Example 2

The video tutorial explains how to determine if two hosts are on the same network by comparing their network prefixes. It provides a task to calculate and compare the network prefixes of two computers with different subnet masks. The tutorial walks through the binary math involved in calculating the network prefixes for each computer and concludes that the hosts are on different networks. The video ends with a prompt for viewers to try another example on their own.

What is the primary goal when comparing two computers' IP addresses and subnet masks?

• To determine if they have the same IP address

• To find out if they belong to the same network

• To check if they have the same subnet mask

• To see if they are using the same operating system

What is the first step in calculating the network prefix for a computer?

• Convert the IP address to hexadecimal

• Convert the subnet mask to hexadecimal

• Convert the subnet mask to decimal

• Convert the IP address to binary

How many bits are set to one in the subnet mask for PC1?

• 8 bits

• 16 bits

• 24 bits

• 32 bits

What is the network prefix for PC2 after applying the subnet mask?

• 172.16.0.0

• 172.16.121.0

• 172.16.200.0

• 172.16.100.0

What conclusion can be drawn if two network prefixes are different?

• The computers have the same subnet mask

• The computers have the same IP address

• The computers are on different networks

• The computers are on the same network
