qn6b


Correct Answer:
qn6c

Explanation:

A common step in troubleshooting connectivity situations is to use the Ping tool to ping the IP address of the computer to which you are trying to connect. When you ping, you send an ICMP Echo message (also known as an ICMP Echo Request message) and get an ICMP Echo Reply message in response. By default, Windows Firewall does not allow incoming ICMP Echo messages, and therefore the computer cannot send an ICMP Echo Reply in response.

Enabling incoming ICMP Echo messages will allow others to ping your computer. However, it also leaves your computer vulnerable to the types of attacks that use ICMP Echo messages. Therefore, we recommended that you enable the Allow incoming echo request setting temporarily, and then disable it when it is no longer needed.
