CompTIA Network+ (N10-007) — Question 386

A network analyzer captures traffic from a host that is sending 802.1q traffic to a Layer 3 switch. Which of the following attacks is occurring?

Answer options

• A. MITM
• B. VLAN hopping
• C. ARP poisoning
• D. Spoofing

Correct answer: B

Explanation

The correct answer is VLAN hopping, which occurs when an attacker exploits the 802.1q tagging mechanism to send packets to a VLAN they are not authorized to access. MITM, ARP poisoning, and Spoofing are different types of attacks that do not specifically relate to the 802.1q traffic being sent to a Layer 3 switch.
