PCNSA Device Management and Services Practice Question

Which two authentication methods can be used for administrative access to the firewall's web interface? (Choose two.)

⚠ Common exam trap

Palo Alto Networks often tests the misconception that any common enterprise authentication protocol (like NTLM or Kerberos) is automatically supported for administrative access, but Palo Alto firewalls specifically support only SAML, local database, RADIUS, LDAP, and TACACS+ for web interface authentication.

Answer choices

Why each option matters

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.

Correct answer & explanation

✓

SAML

SAML (Security Assertion Markup Language) is correct because it enables single sign-on (SSO) for administrative access to the firewall's web interface, allowing integration with external identity providers (IdPs) such as Okta or Azure AD. The local database is correct because it is the default authentication method, where administrators are created and stored locally on the firewall, and credentials are verified against the internal user database. Both methods are natively supported in PAN-OS for web interface (GUI) access.
