CompTIA Network+ (N10-008) — Question 451

A network technician is attempting to increase throughput by configuring link port aggregation between a Gigabit Ethernet distribution switch and a Fast Ethernet access switch. Which of the following is the BEST choice concerning speed and duplex for all interfaces that are participating in the link aggregation?

Answer options

Correct answer: D

Explanation

The correct answer is D, as all interfaces in a link aggregation must operate at the same speed and duplex. Since the access switch is Fast Ethernet, it can only support up to 100MB speed, and using full duplex is optimal for preventing collisions, making it the best choice. Options A and B are incorrect because they either exceed the speed capability of the Fast Ethernet switch or do not match the duplex requirements. Option C is incorrect since it does not utilize full duplex.
