The correct approach is to configure two separate authentication realms on the Cisco WSA—one for internal users using LDAP with Kerberos SSO, and another for external users using RADIUS with MFA—then assign each realm to the appropriate access policies. This works because Cisco WSA supports multiple authentication realms, allowing you to map different authentication methods to different user groups based on policy rather than relying on a single realm or client IP address. On the Cisco SCOR 350-701 exam, this scenario tests your understanding of how to enforce multi-factor authentication for external users while preserving seamless SSO for internal corporate users, a common requirement in hybrid access environments. A frequent trap is assuming you can enforce MFA globally or that a single realm can handle both requirements, but the key is policy-based realm assignment. Memory tip: think “two realms, two policies—internal SSO, external MFA.”
350-701 Content Security Practice Question
This 350-701 practice question tests your understanding of content security. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A company uses Cisco WSA with multiple authentication realms (LDAP, RADIUS, and local). They want to require multi-factor authentication (MFA) for external users but allow single sign-on (SSO) for internal corporate users. Which configuration approach should be used?
Use a single authentication realm with both LDAP and RADIUS configured, and rely on the client IP to choose method
Why wrong: WSA cannot combine realm authentication methods; it uses one realm per policy.
B
Configure a SSL VPN on WSA to differentiate user groups
Why wrong: WSA does not function as an SSL VPN gateway.
C
Configure two authentication realms: one for internal (LDAP with Kerberos SSO) and one for external (RADIUS with MFA), then assign each realm to appropriate access policies
Multiple realms allow different authentication methods per policy.
D
Use SAML authentication with an Identity Provider that supports MFA
Why wrong: SAML is not typically supported for WSA authentication; LDAP and RADIUS are standard.

Correct answer & explanation
✓
Configure two authentication realms: one for internal (LDAP with Kerberos SSO) and one for external (RADIUS with MFA), then assign each realm to appropriate access policies
Option C is correct because Cisco WSA supports multiple authentication realms, allowing you to assign different realms to different access policies. By configuring an internal realm with LDAP and Kerberos SSO for seamless authentication, and a separate external realm with RADIUS and MFA for stronger security, you can enforce MFA only for external users while maintaining SSO for internal users. This approach directly maps authentication methods to user groups based on policy, not on client IP or a single realm.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
Cisco often tests the misconception that a single authentication realm can handle multiple authentication methods simultaneously, or that features like SSLVPN or SAML alone can solve policy-based MFA differentiation without realm-level configuration.
Detailed technical explanation
How to think about this question
Cisco WSA uses authentication realms to define how users authenticate, and each realm can be tied to specific access policies (e.g., based on source IP, time, or user group). Kerberos SSO works by leveraging the user's existing domain credentials via SPNEGO, while RADIUS with MFA typically requires a one-time password or token, which cannot be transparently integrated into a single realm. In a real-world deployment, you would create an internal realm with 'LDAP (Active Directory) + Kerberos SSO' and an external realm with 'RADIUS + MFA', then assign the external realm to a policy that matches external IP ranges or a specific authentication group.

Real-world example
How this comes up in practice
A junior network technician can log in to a core router but cannot reach the enable prompt or configuration mode. The AAA server is authenticating the login — but the authorisation policy only grants privilege level 1, not 15. Authentication (who you are) is working; authorisation (what you can do) is not.
