How many IP addresses does a class C network have? ✔✔254 addresses
What does CIDR stand for? ✔✔CIDR stands for Classless Inter-Domain Routing
Which of the following is a correct form of CIDR notation? ✔✔192.168.1.0/24; CIDR notation
uses a forward slash and then lists the numbers of bits in the subnet mask.
How many octets does a subnet mask have? ✔✔4; A subnet mask is the same length as an IP
address.
, Select examples of routing protocols. Check all that apply. ✔✔Border Gateway Protocol/
Routing Information Protocol
Who is permitted to use non-routable address space? ✔✔Anyone; Anyone can use non-routable
address space.

Destination network
An ARP broadcast is sent to the special MAC address ________. ✔✔FF:FF:FF:FF:FF:FF; ARP
broadcasts are used to ask all devices on a local area network if they're associated with a specific
IP address.
The process of taking a large network and splitting it up into many individual and smaller
subnetworks is known as ________. ✔✔Subnetting; Subnetting allows for much finer-grained
controls of network sizes than the old class system could support.
TTL stands for _______. ✔✔Time to Live; TTL is used to make sure that an undeliverable
packet doesn't spend all of eternity waiting for delivery.
