Question

what is the maximum theoretical size of an ipv4 packet?
○ 1,500 bytes
○ 65,535 bytes
○ 1500 bits
○ 32 bits

Explanation:

The IPv4 header includes a 16-bit Total Length field, which can represent values from 0 to 65535. This field measures the entire IPv4 packet (header + data) in bytes, so the maximum theoretical size is 65535 bytes. 1500 bytes is the common MTU for Ethernet, not the theoretical maximum; options in bits are incorrect as the field uses bytes.

Answer:

B. 65,535 bytes
