Question 260
A FortiOS 7.6 team examines: A data-center egress change must retain the partner allowlisted source IP across the new ISP. 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 data-center egress change must retain the partner allowlisted source IP across the new ISP. The targeted administrative response is: Use an approved FortiGate source NAT IP pool when specific public source addresses are required for outgoing traffic. The relevant failure risk is: An exhausted or misassigned translation pool can prevent sessions or violate source-IP allowlisting at a partner. Validate with: Outbound tests show the agreed public pool addresses and concurrent sessions complete within available translation capacity.
For the observed situation (A data-center egress change must retain the partner allowlisted source IP across the new ISP), the most specific acceptance evidence is: Outbound tests show the agreed public pool addresses and concurrent sessions complete within available translation capacity. It validates the recommended response: Use an approved FortiGate source NAT IP pool when specific public source addresses are required for outgoing traffic. This addresses the documented risk: An exhausted or misassigned translation pool can prevent sessions or violate source-IP allowlisting at a partner.
Incorrect Answers
Fsso group filter and policy authorization (2.4) would demonstrate or implement: Users from the approved directory group match the protected rule and other groups cannot reach the resource. The case states: A data-center egress change must retain the partner allowlisted source IP across the new ISP. The most direct paired action and test is: Use an approved FortiGate source NAT IP pool when specific public source addresses are required for outgoing traffic.
Address objects and policy scope (2.1) addresses another technical failure: Wrong subnet masks or interface directions can permit unrelated clients or cause expected traffic to miss the rule. This case instead tests IP pool source nat address selection; the choice measures or changes another part of the system.
Firewall policy logging and traceability (2.1) would demonstrate or implement: Without consistent allowed and denied event visibility, teams cannot determine which policy produced an outage. The paired-answer requirement concerns IP pool source nat address selection; this alternative does not provide the matching intervention and separate acceptance evidence.
