Palo Alto Networks Certified Network Security Administrator (PCNSA) — Question 88

Which three types of authentication services can be used to authenticate user traffic flowing through the firewall's data plane? (Choose three.)

Answer options

• A. SAML 2.0
• B. Kerberos
• C. TACACS
• D. TACACS+
• E. SAML 1.0

Correct answer: A, B, D

Explanation

The correct answers are A, B, and D because SAML 2.0, Kerberos, and TACACS+ are all recognized authentication services that can effectively handle user traffic. TACACS is an older protocol and SAML 1.0 is outdated, making them unsuitable options in this context.
