ICND2: Interconnecting Cisco Networking Devices Part 2 (legacy) — Question 61

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

Answer options

• A. FCS
• B. SOF
• C. SA
• D. DA

Correct answer: C

Explanation

The correct answer is C, SA (Source Address), which must be a unique identifier for the device sending the frame. The other options, FCS (Frame Check Sequence), SOF (Start of Frame), and DA (Destination Address), do not strictly require individuality in the same way as the source address does.
