PCNSE Secure Access and VPN Practice Question
A company integrates GlobalProtect with SAML for SSO. Users report that after authentication, they receive a 'Portal cannot be reached' error. The firewall logs show the SAML authentication succeeded. What should the administrator check?
⚠ Common exam trap
The trap here is that candidates see 'SAML authentication succeeded' and assume the issue is with SAML configuration (e.g., profile or certificate), but the error is a post-authentication SSL/TLS handshake failure, not an authentication failure.
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
✓
The SSL/TLS service profile on the portal is not bound to the correct certificate.
The 'Portal cannot be reached' error after successful SAML authentication indicates the browser cannot establish a trusted SSL/TLS connection to the portal. The SAML authentication succeeded, so the issue is not with the SAML profile or certificate. The SSL/TLS service profile on the portal must be bound to a certificate that matches the portal's FQDN and is trusted by the client browser; otherwise, the browser will block the connection, causing this error.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
The user's browser is blocking pop-ups from the portal.
Why it's wrong here
Incorrect. Pop-up blocking may prevent SAML redirects but would not cause 'Portal cannot be reached'.
- ✗
The GlobalProtect portal agent is not set to use the correct SAML profile.
Why it's wrong here
Incorrect. If SAML profile were incorrect, authentication would fail.
- ✗
The SAML identity provider's certificate is not imported on the firewall.
Why it's wrong here
Incorrect. Imported certificate is required for SAML to succeed, which it did.
- ✓
The SSL/TLS service profile on the portal is not bound to the correct certificate.
Why this is correct
Correct. A mismatched certificate causes the browser to block the portal after SAML.
