Implementing Cisco Network Security (IINS, legacy) — Question 25

Which attack can be prevented by OSPF authentication?

Answer options

• A. smurf attack
• B. IP spoofing attack
• C. Denial of service attack
• D. buffer overflow attack

Correct answer: B

Explanation

OSPF authentication is designed to prevent unauthorized devices from participating in OSPF routing, which effectively mitigates IP spoofing attacks that rely on impersonating a legitimate device. The other options, such as smurf attacks, denial of service attacks, and buffer overflow attacks, are not directly related to the integrity and authentication of routing protocols.
