Questions: When could you use MAC spoofing with your nmap scan? A If you ran a fragmentation attack at the same time B If you were remote C If you were on the local network D If your target is running DNS

The answer is C: If you were on the local network.

Explanation for each option:

A. If you ran a fragmentation attack at the same time:

• This option is incorrect. While fragmentation attacks and MAC spoofing can be used together in some scenarios, MAC spoofing is not specifically dependent on running a fragmentation attack.

B. If you were remote:

• This option is incorrect. MAC spoofing is typically used when you are on the same local network as the target. When you are remote, you do not have direct access to the local network's MAC addresses.

C. If you were on the local network:

• This option is correct. MAC spoofing is most effective when you are on the same local network as the target. It allows you to change your MAC address to another one on the local network, which can help in bypassing certain network security measures or in evading detection.

D. If your target is running DNS:

• This option is incorrect. The target running DNS does not have a direct relationship with the need to use MAC spoofing. MAC spoofing is more about network access and evasion techniques rather than the specific services running on the target.

Summary: MAC spoofing is most effectively used when you are on the local network, as it allows you to change your MAC address to another one on the same network, aiding in bypassing network security measures or evading detection. Therefore, the correct answer is C: If you were on the local network.
