C) 100 Meters
What type of cable a connector does 100BaseFX use?
A) Multimode fiber with ST or SC connectors.
B) STP Cat 6 with RJ-45 connectors.
C) Single-Mode fiber with MT-RJ connectors.
D) UTP Cat 5e with RJ-4 Connectors
A) Multimode Fiber with ST or SC connectors.
How many pairs of wires do 10BaseT and 100BaseT use? A) 4 B) 1 C)3 D)2
D) Two pairs
What standard does IEEE 802.3ab describe? A) 1000BaseLX B) 1000BaseT C) 100BaseT D) 1000BaseSX
B) IEEE 802.3ab is the 1000BaseT Standard (also known as Gigabit Ethernet)
What is the big physical difference between 1000BaseSX and 100Base FX?
A) 1000BaseSX uses the SC connector exclusively.
B) 1000BaseSX is single-mode, whereas 100BaseFX is multimode.
C) 1000BaseSX uses the ST connector exclusively.
D) There is no difference.
A) While 1000BaseSX look similar to 100BaseFX, the former does not allow the use of the ST connector.
What is the maximum distance for 1000BaseLX without repeaters? A) 1 Mile B) 2500 Meters C) 20000 Feet D) 5000 Meters
D) 1000BaseLX can go fo 5000 meters.
What is a big advantage to using fiber-optic cable?
A) Fiber is common glass; therefore, it’s less expensive.
B) Fiber is not affected by EMI.
C) Making custom cable lengths is easier with fiber.
D) All that orange fiber looks impressive in the network closet.
A) Because fiber uses glass and light, it is not affected by EMI.
How may wire pairs does 1000BaseT use? A) 1 B) 2 C) 3 D) 4
D) 1000BaseT uses all four pairs of wires.
What is the standard conector for the 10 GbE fiber standard? A) ST B) SC C) MT-RJ D) There is no standard
D) There is no standard connector; the 10GbE committee has left this up to the manufacturers.
What is the maximum cable length of 10GBaseT on Cat 6? A) 55 Meters B) 100 Meters C) 20 Meters D) 70 Meters
A) With a Cat 6 cable, 10GBaseT is limited to 55 Meters
What is Broadband?
You can get multiple signals to flow over the same wire at the same time.
