Final answer:
The best answer for the acceptable signal loss in a good patch cord is D. 1 dB, which indicates minimal signal loss and good performance.
Step-by-step explanation:
A good patch cord, which is used in networking to connect electronic devices together, should have minimal signal loss to ensure efficient data transmission. When we talk about signal loss in patch cords, it is expressed in decibels (dB). The question refers to acceptable levels of loss a patch cord should have. Given the options, the best answer is D. 1 dB. A loss of less than 1 dB is generally considered good for a patch cord, as it indicates only a minimal signal loss is occurring. This is important for maintaining the integrity of the signal being transmitted through the cord.
