1. Which of the following are the most likely combination of items that make 
up the ‘cloud’?
a. A run of fiber optic cables along the highway only.
b. A run of copper cabling along the highway only.
c. A wireless connection provided by a satellite.
d. A run of fiber optic cable along that connects to a number of 
networks built around towns and other universities, which in turn 
connect back into the fiber optic cable at a diferent point or take a 
secondary, entirely separate, route down to NYC.2. Which of the following media likely connects the datacenter in bufalo to 
the greater city and its clients? (Technically, there could be two answers)
a. Copper cable
b. Fiber optic cable
c. Console cable
d. Radio waves
3. Which of the following media likely connects the computers in the local 
network shown to their respective switch?
a. Copper cable
b. Fiber optic cable
c. Console cable
d. Radio waves
4. Which of the following combinations are valid for the local network 
shown? (only one network is present) (/24 means 255.255.255.0 --- /16 
means 255.255.0.0, etc). THINK
a. Router: 10.1.0.1 /8 Wired Computer: 10.2.0.1/8 Wireless Laptop: 
10.1.0.2/8
b. Router: 10.1.0.1 /16 Wired Computer: 10.1.0.2/8 Wireless Laptop: 
10.1.0.2/8
c. Router: 192.168.1.1 /24 Wired Computer: 192.168.1.1/24 Wireless 
Laptop: 192.168.1.1/24
d. Router: 192.168.1.1 /24 Wired Computer: 192.168.2.1/24 Wireless 
Laptop: 192.168.3.1/24
e. Router: 10.1.0.1 /16 Wired Computer: 10.1.0.2/16 Wireless 
Laptop: 10.2.0.3/16
5. Let’s say the city of bufalo ‘has two interfaces’, much like a cisco switch 
that we have been configuring. An inside interface, that faces the 
datacenter and an outside interface, that faces the cloud. If we shut of
the outside interface which of the following is true?
a. New York can ping bufalo, but bufalo can’t ping New York.b. New York can ping Bufalo and the local network in Bufalo can ping 
New York.
c. All the machines already in bufalo can still ping each other, but 
can’t ping New York, everyone can still ping Alfred University 
(outside the limits of Bufalo)
d. All the machines already in bufalo can still ping each other but not 
New York. They can’t ping Alfred.
