Jaden, a network administrator at an organization, used the ping command to check the status of a system connected to the organization's network. He received an ICMP error message stating that the IP header field contains invalid information. Jaden examined the ICMP packet and identified that it is an IP parameter problem.
Identify the type of ICMP error message received by Jaden in the above scenario.

Answer options

• A. Type =12
• B. Type = 8
• C. Type = 5
• D. Type = 3

Correct answer: A

Explanation

The correct answer is Type = 12, which signifies an IP parameter problem. This type is specifically related to issues with the IP header. The other types, such as Type = 8 (echo request), Type = 5 (redirect), and Type = 3 (destination unreachable), do not pertain to IP header errors.
