Suggested answer: A

Explanation:

The default size of a Windows Echo Request packet, commonly known as a ping request, is 28 bytes. This size is derived from the following components:

ICMP Header: The Internet Control Message Protocol (ICMP) header is 8 bytes.

IPv4 Header: The IP header for an IPv4 packet is typically 20 bytes.

Therefore, the total size of the default Windows Echo Request packet is 28 bytes (8 bytes for ICMP header + 20 bytes for IPv4 header).

'Ping (networking utility),' Wikipedia, Ping.

'ICMP Header Format,' Cisco, ICMP Header.
