What is the maximum bandwidth of a T1 point-to-point connection? (CCNA 200-301)

Correct answer: A. 1.544 Mbps.
A T1 point-to-point connection, also known as a DS1 (Digital Signal 1) connection, has a maximum bandwidth of 1.544 Mbps.

The key characteristics of a T1 connection are:
It is a digital leased line that provides a dedicated, point-to-point connection between two locations.
It operates at a data rate of 1.544 Mbps.
It uses time-division multiplexing to carry 24 individual 64 Kbps channels.
The total bandwidth of 1.544 Mbps is the sum of the 24 individual 64 Kbps channels.

The other options are incorrect:
B. 2.048 Mbps - This is the maximum bandwidth of an E1 connection, which is a European equivalent of a T1 line.
C. 34.368 Mbps - This is the maximum bandwidth of a T3 (DS3) connection, which is a higher-speed digital leased line.
D. 43.7 Mbps - This is not a standard bandwidth for any common digital leased line service.

Therefore, the maximum bandwidth of a T1 point-to-point connection is 1.544 Mbps.
