Palo Alto Networks Certified Network Security Engineer (PCNSE) — Question 412

Which three multi-factor authentication methods can be used to authenticate access to the firewall? (Choose three.)

Answer options

• A. One-time password
• B. User certificate
• C. SMS
• D. Voice
• E. Fingerprint

Correct answer: A, C, D

Explanation

The correct answers are A, C, and D because one-time passwords, SMS, and voice calls are all examples of multi-factor authentication methods that provide an additional layer of security. Options B and E, while useful for authentication, do not fit the standard multi-factor authentication methods commonly used for firewall access.
