Question 500
A FortiOS 7.6 team examines: A newly created SD-WAN zone changes the matched firewall rule and application events disappear. Select TWO complementary choices: the most appropriate corrective action AND the specific evidence confirming success.
Explanation
Correct Answers
The reported FortiOS 7.6 condition is: A newly created SD-WAN zone changes the matched firewall rule and application events disappear. The targeted administrative response is: Apply application-control inspection only to appropriate policy traffic and validate the intended user, interface and application combination. The relevant failure risk is: A profile applied to the wrong policy can miss the affected clients or disrupt unrelated approved applications. Validate with: The intended clients show the specified application-control decisions while excluded groups remain on their own policies.
For the observed situation (A newly created SD-WAN zone changes the matched firewall rule and application events disappear), the most specific acceptance evidence is: The intended clients show the specified application-control decisions while excluded groups remain on their own policies. It validates the recommended response: Apply application-control inspection only to appropriate policy traffic and validate the intended user, interface and application combination. This addresses the documented risk: A profile applied to the wrong policy can miss the affected clients or disrupt unrelated approved applications.
Incorrect Answers
Antivirus inspection of encrypted downloads (3.4) would demonstrate or implement: A controlled HTTPS test shows the approved file is inspected under the intended full-inspection policy without trust errors. The case states: A newly created SD-WAN zone changes the matched firewall rule and application events disappear. The most direct paired action and test is: Apply application-control inspection only to appropriate policy traffic and validate the intended user, interface and application combination.
Certificate-chain expiry and handshake diagnosis (3.1) would demonstrate or implement: Blanket bypass of certificate validation can conceal expired or untrusted servers and unsafe TLS behavior. This choice can be useful for that problem, but it does not establish the Application control profile and firewall policy scope control being assessed here.
TLS inspection exceptions and sensitive traffic (3.1) addresses another technical failure: Overly broad exclusions can create uninspected channels; blanket interception can break approved confidential services. The required paired action and test concerns Application control profile and firewall policy scope; a passing result for this alternative could leave that requirement unresolved.
