Which six-byte field in a basic Ethernet frame must be an individual address?

Which six-byte field in a basic Ethernet frame must be an individual address?

A. SOF
B. FCS
C. DA
D. SA

Correct Answer: D
Explanation

Explanation/Reference:
The picture below shows the fields in IEEE 802.1Q frame.

The SA field is the source address field. The field should be set to the MAC address of the switch port that transmits the frame. It is a 48-bit value (6 bytes). The receiving device may ignore the SA field of the frame. In fact there is another correct answer for this question: DA (Destination Address) which also consists of 6 bytes. Maybe there is a mistake or typo in this question.
