A network administrator wants to connect a new building to an existing network using cable that can provide a secure connection and is not susceptible to electrical interference. The new building is approximately 800 meters away from the existing network. Which cable type should the administrator choose?
A: Category 5 STP
B: Category 6 UTP
C: coaxial
D: fiber optic
I have another question, why do I have people telling me to "do your own homework" and "stop posting trivia questions"? Please just answer the question and feel sorry for me because my dad forced me to sign up for this hardware class even though I really wanted to be in AP Programming.

Coaxial cable and fiber optic are both relatively immune to electrical interference.
Coax is not secure unless encased in a secure container. It is possible to tap coax without cutting it, I've done it. Fiber optic cannot be tapped without cutting it, which makes it secure if you watch for outages.
The distance also indicates fiber. Fiber is cheaper and provides better S/N ratios in long runs. Coax specs may allow 800 meter runs these days, but old Ethernet coax could not go that far without repeaters.
So "D".

If you're taking a hardware class, this should be covered pretty early on. I'll give you a hint though, the abbreviations at the end of Category 5 and Category 6 stand for 'Shielded Twisted Pair' and 'Unshielded Twisted Pair'.

D. Fiber Optic
Reason: Not susceptible to electrical interference and can be strewn for very long distances. Uses light instead of wire although the con with this is the price (very expensive)

I work in an IT department, mainly PC tech work. I don't do much network admin stuff, but I always hear him talking about the fiber optic cable between buildings.
It's gotta be fiber optic dude.

Probably because they are right, try to learn or drop out.
D.
Pretty useless knowing answers without the reasons why, you ain't going to have a computer with Internet access to google answers in any exams.
Cat 5 and 6 cant go over 100 Meters without a switch or repeater etc..., and Co-axle of long lengths is susceptible to interference.

Obviously Fiber Optic if you want the fastest speed. Twisted pair can't go nearly that far. Coax is a little out of range.

Fiber optic, you should do your own homework, because you should know how the hardware works.

dude you have choices either you drop this class
or do you homework, because you will need to know basic and advance things.
i don't feel sorry for you, its your choice not your father
how you wanted to be API programmer and asking these kind of questions. Now I understand why so many IT jobs are being outsourcing.

my guess is fiber optic, if you have the ability to do that

I don't and won't feel sorry for you. I also wont help you. You learn by making mistakes.
