An IP packet has arrived with the first 8 bits as 0100 0010. Which of the following is correct?
- A. The number of hops this packet can travel is 2.
- B. The total number of bytes in header is 16 bytes
- C. The upper layer protocol is ICMP
- D. The receiver rejects the packet
Answer: D. The receiver rejects the packet
Explanation: First 4 bits (Version): 0100 = 4 (IPv4).\nNext 4 bits (IHL): 0010 = 2. \nHeader Length = IHL $\times$ 4 = $2 \times 4 = 8$ bytes.\nMinimum IPv4 header length is 20 bytes. Since 8 < 20, the header is invalid and rejected.
