Implementing and Operating Cisco Security Core Technologies (SCOR) — Question 482

For which type of attack is multifactor authentication an effective deterrent?

Answer options

• A. syn flood
• B. phishing
• C. teardrop
• D. ping of death

Correct answer: B

Explanation

Multifactor authentication is particularly effective against phishing attacks because it requires additional verification beyond just the password, making it harder for attackers to gain unauthorized access even if they have the victim's credentials. The other options, such as syn flood, teardrop, and ping of death, are types of denial-of-service attacks that do not involve credential theft and therefore are not mitigated by multifactor authentication.
