NSE7 Advanced VPN and Zero Trust Practice Question
An administrator configures a ZTNA proxy rule to allow access to an internal application. Users can connect to the FortiGate ZTNA gateway but receive a '403 Forbidden' error. Which step should the administrator take to resolve the issue?
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
✓
Check that the ZTNA proxy rule's action is set to 'accept' and the correct tags are specified
A 403 error on ZTNA typically indicates that the user's device does not have the required ZTNA tags. The administrator must ensure the FortiClient has the correct tags assigned based on compliance.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Disable the 'require ZTNA tag' option on the proxy rule
Why it's wrong here
This would bypass security, not a recommended fix.
- ✓
Check that the ZTNA proxy rule's action is set to 'accept' and the correct tags are specified
Why this is correct
The proxy rule controls access based on tags. Missing tags cause forbidden errors.
- ✗
Ensure the application is reachable from the FortiGate with a ping
Why it's wrong here
Reachability would cause different errors (timeout, not 403).
- ✗
Verify that the application's firewall policy has an SSL inspection profile applied
Why it's wrong here
SSL inspection is not directly related to ZTNA access control.
