Solution

The correct answer is TCP protocol

EXPLANATION:

The header of the IP datagram given is in hexadecimal format.

Size of the header is 20 to 60 Bytes

Version = 4 bits = (0100)2 (It is IPv4)

Header length = (0101)2 to (1111)2 = 5 bits to 15 bits

Total length = 216 bits

Identification = 216 bits

Fragment Offset = 216 bits

Time to live = 28 bits

Protocol = 28 bits

Header Checksum = 216 bits

SOLUTION:

IP Datagram = 45000054 00030000 2006.......

                20                              06             

  

The first byte of the IP header contains two fields: the version and the Internet Header Length (IHL). In your case, the first byte is "45" in hexadecimal.

The 9th byte (which is the 7th and 8th characters in the hexadecimal representation) identifies the protocol of the contained data.

In the given header, the protocol value is "06".

This value corresponds to the TCP protocol according to the Assigned Internet Protocol Numbers. Therefore,

The payload being carried by the packet is using the TCP protocol. So, the correct answer is: TCP protocol
