Lab 7.1
Exercise 7.1.1
Its impractical for whole organization to own a whole WAN because it could be great distances or overseas or across the country. It would be better to own the LAN to be able to control the cost of the set up
Exercise 7.1.2
Increasing the distance would help due to making easier to see both a strong and weak signal
Exercise 7.1.3
Media
Infrastructure summary UTP
Phone Lines
Has 4 pair of 22-24 gauged wires
Coaxial
TV Cable
Can be ran over long distances
Fiber-optic
Single mode and multi mode
Use customized infrastructure to run dedicated connections

Exercise 7.1.4
Wan wireless media

Satellite
Used to provide internet and mobile broadband
WiMAX
Provides 30 to 40 Mbps of daa ransfe
HSPA+
Uses braod band with spectrum
Radio frequency
What WAN uses to communiact

Lab 7.2.1
Benefits of a leased line are flexible bandwidth and High quality performance
Lab 7.2.2
The benefits of a partial in the cost and a full meh would be required where large sums of money and data are exchanged and can have almost none down time.
Exercise 7.2.3
Its easier to wire up and understand compaired to half mesh and you would want the half mesh when you must have redudancy
Exercise 7.2.4

Circuit Classification
Total Bandwidth Mbps
Summary
T1
1.544
Private data line connection two or more locations
E1
2
Uses 32 channels for communications
E3
34.4

T3
44.7
Used for long distances and core of a business network at their head quarters

Lab 7.3
Exercise 7.3.1

I would use a Half-Mesh because the their need to have constant communication with almost no down time
Exercise 7.3.2
LAN to LAN tunnels, MPLS network and VPN site to site I would chose the MPLS network its more reliable.
