- A
User-ID is configured
User-ID is required to map users to IP addresses and use user attributes in policies.
- B
The firewall is in transparent mode
Why wrong: Authentication Policy works in any mode.
- C
SSL decryption is enabled
Why wrong: Authentication Policy works without SSL decryption.
- D
A security policy rule exists with user attributes
Why wrong: Authentication Policy is independent of security policies.
- E
An authentication profile is configured
The authentication profile defines the method (e.g., SAML, LDAP) used to authenticate.

PCNSE Practice Question: Securing Users and Applications with Authentication
This PCNSE practice question tests your understanding of securing users and applications with authentication. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. 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.
Which TWO are prerequisites for using Authentication Policy? (Choose two.)
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
✓
User-ID is configured
User-ID must be configured because Authentication Policy relies on user identity information to enforce access controls based on who the user is, not just IP addresses. Without User-ID, the firewall cannot map users to traffic, making authentication policies ineffective. This prerequisite ensures the firewall can identify users via agents, captive portal, or other methods.
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
The trap here is that candidates often confuse prerequisites with features that enhance security (like SSL decryption) or confuse the order of configuration steps, thinking a security rule with user attributes must exist before the authentication policy can be used.
Detailed technical explanation
How to think about this question
Authentication Policy uses User-ID to map IP addresses to usernames via protocols like LDAP, Kerberos, or captive portal, and then applies authentication profiles that can enforce multi-factor authentication or single sign-on. Under the hood, the firewall creates authentication entries in the user-to-IP mapping table, which are then matched against security policy rules. In real-world deployments, failing to configure User-ID first leads to authentication policies being skipped because the firewall cannot associate traffic with a specific user.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
TExam Day Tips
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A practitioner preparing for the PCNSE exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.
