CompTIA Security+ (SY0-501) — Question 373

Which of the following enables sniffing attacks against a switched network?

Answer options

• A. ARP poisoning
• B. IGMP snooping
• C. IP spoofing
• D. SYN flooding

Correct answer: A

Explanation

ARP poisoning is a technique that allows an attacker to associate their MAC address with the IP address of another host, enabling them to intercept traffic intended for that host. On the other hand, IGMP snooping is used to optimize multicast traffic, IP spoofing is a method of forging the source IP address in packets, and SYN flooding is a type of denial-of-service attack that doesn't facilitate sniffing.
