CompTIA A+ 1101 Network Cables

Question 1

• common for ethernet connections
• balanced pair operation
• each cable has equal and opposite signals
• the twist keeps a single wire constantly moving away from the interface
• pairs in the same cable have different twist rates

Answer 1

Twisted Pair Copper Cabling

Question 2

• 1 gigabyte standard
• 100 meter maximum supported distance
• CAT5e is enhanced CAT5

Answer 2

CAT5 and CAT5e Twisted Pair Copper Cabling

Question 3

CAT6:
- 10 gigabyte standard
- 55 meter maximum supported distance for an unshielded cable, 100 meter maximum supported distance for a shielded cable

CAT6A:
- augmented CAT6
- 10 gigabyte standard
- 100 meter maximum supported distance

Answer 3

CAT6 and CAT6A Twisted Pair Copper Cabling

Question 4

• commonly used on cable modems, cable televisions, and high-speed internet over cable
• made of a wire conductor, dielectric insulator, metal shielding, and plastic jacket

Answer 4

Coaxial Cable

Question 5

• fire resistant cable
• FEP (fluorinated ethylene polymer) or low smoke PVC
• may not be as flexible as PVC cabling

Answer 5

Plenum-Rated Cable

Question 6

• additional shielding protects against interference
• shielding may be around each pair, or the whole cable
