IPv4 addresses are

• 32 bits wide
• 48 bits wide
• 4 bits wide
• of any size in bits

The left-hand part of an IPv4 address is

• the Network-id
• the Host-id
• the MAC address
• the computer’s memory size

The right-hand part of an IPv4 address is

• the Network-id
• the Host-id
• the MAC address
• the identity of the computer’s network card

A /24 netmask means

• a set of 256 IP addresses
• a set of 128 IP addresses
• a set of 64 IP addresses
• a set of 32 IP addresses

A /27 netmask means

• a set of 256 IP addresses
• a set of 128 IP addresses
• a set of 64 IP addresses
• a set of 32 IP addresses

What is the dotted decimal netmask for a /27 network?

• 255.255.255.0
• 255.255.255.128
• 255.255.255.192
• 255.255.255.224

You need to buy IP address for a network with 50 end devices. You should buy

• A /24 sized subnet
• A /25 sized subnet
• A /26 sized subnet
• A /27 sized subnet

A “Classless” routing protocol

• knows about subnets of all different sizes
• only knows about /8, /16 and /24 network sizes
• has a lot of charisma and class
• only works in a classroom

Which routing protocol is classless?

• RIP version 1
• EIGRP
• HTTP
• TCP
