Shiva is working as a network engineer and recently he got an assignment to design a reliable but cheaper  Ethernet connection between two offices. The Details are like this.

• Two buildings are just 150 meters apart.
• There can be frequent problems with  volatge potential differences between two offices.

Which media type Shiva should use?

a. STP          b. coaxial      c. Fiber optic

---

I.  a , b or c

II. b or c

III. b only

Answer 1

Should be coaxial as it is cheaper than Fiber and can go up to 500m. Though I'm not sure this is applicable in practice.

Answer 2

ans is coaxial

Answer 3

• STP can go upto 100 m,  Coaxial cable can go upto 500 m while Optical Fibre has no range limit. Since two buildings are just 150 meters apart, we can use Coaxial cable or Fibre optic.
• There can be frequent problems with  volatge potential differences between two offices. SInce Optical fibre is completely protected from electrical glitches, we can use it. But Coaxial cables are not completely reliable in this case

Answer is optic fibre
