Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

C is correct because VoIP packet headers sum to 40 bytes: IP header (20 bytes minimum) + UDP header (8 bytes) + RTP header (12 bytes) = 40 bytes total overhead per voice packet. A (20 bytes) accounts only for IP. B (400 bytes) and D (4000 bytes) are grossly inflated and not representative of actual protocol header sizes.
