Correct Answer: B
Explanation:
ADSL2+ Specifications :
Downstream Rate : ADSL2+ supports a maximum downstream rate of 24 Mbit/s under ideal conditions.
Upstream Rate : The maximum upstream rate is typically 1 Mbit/s to 3.5 Mbit/s , depending on the line conditions.
Transmission Distance : The maximum transmission distance for ADSL2+ is approximately 5.5 km , not 6.5 km. Beyond this distance, signal attenuation becomes significant, reducing performance.
Why FALSE?
The statement incorrectly states that the maximum transmission distance is 6.5 km, which exceeds the typical range for ADSL2+.
Thus, the correct answer is B .
