Question 280
A FortiOS 7.6 team examines: Two departments need separate public source pools while the system uses a centralized NAT table. Select TWO complementary choices: the most appropriate corrective action AND the specific evidence confirming success.
Explanation
Correct Answers
For the observed situation (Two departments need separate public source pools while the system uses a centralized NAT table), the most specific acceptance evidence is: Session and translation inspections show the intended matched central or policy-based NAT rule for each tested flow. It validates the recommended response: Determine whether the FortiGate is using central SNAT or policy NAT and manage translations in the corresponding configuration model. This addresses the documented risk: Changing only firewall-policy NAT settings when central NAT is authoritative can leave the source address unchanged.
The reported FortiOS 7.6 condition is: Two departments need separate public source pools while the system uses a centralized NAT table. The targeted administrative response is: Determine whether the FortiGate is using central SNAT or policy NAT and manage translations in the corresponding configuration model. The relevant failure risk is: Changing only firewall-policy NAT settings when central NAT is authoritative can leave the source address unchanged. Validate with: Session and translation inspections show the intended matched central or policy-based NAT rule for each tested flow.
Incorrect Answers
Top-down firewall policy matching (2.1) would demonstrate or implement: A broad early permit or deny may match before a later more-specific rule, causing unintended access or blockage. This case instead tests Central snat versus policy nat selection; the choice measures or changes another part of the system.
Security profiles attached to permitted policies (2.1) addresses another technical failure: Creating a web-filter or IPS profile alone offers no protection when the matched allow policy does not apply it. The required paired action and test concerns Central snat versus policy nat selection; a passing result for this alternative could leave that requirement unresolved.
Radius authentication and shared secret checks (2.3) would demonstrate or implement: A controlled authentication request receives the expected accept or reject result and maps policy groups correctly. The paired-answer requirement concerns Central snat versus policy nat selection; this alternative does not provide the matching intervention and separate acceptance evidence.
