A.

DNS

B.

FTP

C.

PoE

C.

VTP trunking

D.

Port forwarding

B.

802.11b

C.

802.11g

D.

802.11n

transfer speed of 11 Mbps, at a range of about 100 m indoors and up to 200 metres outdoors (or even beyond that, with directional antennas.)

Hypothetical speed

Range(indoors)

Range(outdoors)

11 Mbits/s

50 m

200 m

5.5 Mbits/s

75 m

300 m

2 Mbits/s

100 m

400 m

1 Mbit/s

150 m

500 m

QUESTION 109

Which of the following WAN technologies has the HIGHEST latency?

 

A.

ADSL

B.

LTE

C.

Satellite

D.

WiMAX

 

Correct Answer: C

Explanation:

Satellite WAN latency is the delay caused by the physical distance a signal must travel from earth, to the satellite, and back to earth to complete a round-trip transmission. Because of the physics involved in the round-trip-time (RTT), end-to-end latency can take 600 milliseconds or more due to geosynchronous satellites orbiting miles above the earth.
