A technician is testing a diode using a DMM in the diode test mode. She measures 0.7V when the diode is forward biased and the DMM indicates OL when the diode is reverse biased. What do these test results indicate?
A) The results indicate the diode is defective because of the OL indication when the diode is reverse biased.
B) The results indicate that this is definitely not a zener diode.
C) The results indicate she is not testing the diode correctly.
D) The results indicate the diode is likely functioning correctly.

The results indicate the diode is likely functioning correctly because a forward-biased diode typically shows a voltage drop around 0.7V for silicon diodes, and an OL (over-limit) reading in reverse bias indicates it is not conducting, which is expected behavior for a functioning diode.
