The answer is to configure a ZTNA rule with a ZTNA tag requirement. This is correct because ZTNA enforces posture assessment by requiring the client to present a specific ZTNA tag, which is assigned by FortiClient EMS only when the endpoint meets compliance policies. The access proxy rule then checks for this tag before granting access to the internal application, effectively blocking non-compliant devices. On the Fortinet NSE 4 exam, this concept tests your understanding of how ZTNA tags bridge endpoint posture with access control—a common trap is confusing the access proxy’s general settings with the rule-level tag enforcement. Remember that the tag is the gatekeeper: if the client lacks the correct tag, the rule denies access, not the proxy itself. A helpful memory tip is “Tag first, access second”—the ZTNA tag requirement is what enforces the posture check, not the proxy’s authentication or encryption settings.
NSE4 High Availability and Diagnostics Practice Question
This NSE4 practice question tests your understanding of high availability and diagnostics. 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.
An administrator is configuring ZTNA (Zero Trust Network Access) on a FortiGate. The administrator needs to ensure that only clients with a valid posture assessment can access an internal application. Which access proxy setting must be configured to enforce this requirement?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Configure a ZTNA rule with a ZTNA tag requirement
ZTNA uses access proxies to secure access. To enforce client posture assessment, the administrator needs to configure an access proxy with a ZTNA rule that includes a ZTNA tag matching the required posture. The tag is assigned by FortiClient EMS based on compliance. The access proxy rule can then require that the client presents a valid ZTNA tag.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
Enable SSL deep inspection on the access proxy
Why it's wrong here
SSL inspection decrypts traffic but does not enforce posture.
✓
Configure a ZTNA rule with a ZTNA tag requirement
Why this is correct
ZTNA rules use tags to enforce security posture. The rule must be set to require a specific tag that is only assigned to compliant clients.

✗
Set the access proxy to use certificate-based authentication
Why it's wrong here
Certificate authentication verifies identity, not posture.
✗
Enable multi-factor authentication on the access proxy
Why it's wrong here
MFA provides additional authentication, not device posture.
Common exam traps
Common exam trap: answer the scenario, not the keyword
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.

How to think about this question
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.

TExam Day Tips
→Underline the problem statement mentally.
→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 NSE4 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.

Variation 1. A FortiGate administrator is configuring ZTNA (Zero Trust Network Access) to secure access to an internal application. Which two components must be configured to create a ZTNA rule? (Choose two.)
hard
A.ZTNA tag
✓ B.ZTNA gateway
C.VPN tunnel
✓ D.ZTNA application
E.SSL certificate
Why B: Option C and D are correct. ZTNA rules require a ZTNA gateway (the FortiGate acting as proxy) and a ZTNA application (the internal resource). The rule maps external access to the internal application via the gateway.
