PCNSE Practice Question: Securing Users and Applications with Authentication
To reduce the number of authentication prompts for users accessing multiple applications through the firewall, which configuration is recommended?
⚠ Common exam trap
Many exam-takers confuse increasing the authentication timeout (Option A) with reducing prompts, but timeout only extends the session lifespan, not the number of prompts per application; the key is the session cookie mechanism that ties all application requests to a single authenticated session.

Correct answer & explanation
✓
Enable session cookies in the authentication policy
Enabling session cookies in the authentication policy allows the firewall to store a session cookie on the user's browser after the first successful authentication. This cookie is then presented for subsequent requests to different applications, eliminating repeated authentication prompts. The firewall validates the cookie against the existing user session, providing a seamless single sign-on (SSO) experience without requiring re-authentication for each application.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Increase the authentication timeout value
Why it's wrong here
Timeout affects idle time, not the number of prompts.
- ✓
Enable session cookies in the authentication policy
Why this is correct
Session cookies maintain authentication state and reduce prompts.
- ✗
Use certificate-based authentication
Why it's wrong here
Certificates eliminate usernames/passwords but may not reduce prompts if not cached.
- ✗
Disable authentication for commonly used applications
Why it's wrong here
This weakens security by allowing unauthenticated access.
