A technician has a network with a mix of newer and older equipment. Which of the following
settings would dynamically configure whether to use full or half duplex?

A.
Transmission speed

B.
Frequency

C.
Auto-negotiate

D.
Distance

Explanation:
Autonegotiation is an Ethernet procedure by which two connected devices choose common
transmission parameters, such as speed, duplex mode, and flow control. In this process, the
connected devices first share their capabilities regarding these parameters and then choose the
highest performance transmission mode they both support.
