CompTIA Security+ (SY0-501) — Question 397

While performing surveillance activities, an attacker determines that an organization is using 802.1X to secure LAN access.
Which of the following attack mechanisms can the attacker utilize to bypass the identified network security?

Answer options

• A. MAC spoofing
• B. Pharming
• C. Xmas attack
• D. ARP poisoning

Correct answer: A

Explanation

The correct answer is A, MAC spoofing, as it allows an attacker to impersonate a legitimate device on the network by changing the MAC address. The other options, such as Pharming, Xmas attack, and ARP poisoning, do not specifically target 802.1X authentication mechanisms and are less effective for bypassing LAN access controls.
