Question 210
A FortiOS 7.6 team examines: A test machine in an adjacent subnet can access a resource reserved for a separate tenant. 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 test machine in an adjacent subnet can access a resource reserved for a separate tenant. The targeted administrative response is: Maintain accurate address objects and interface pairings so firewall policies select the intended source and destination networks. The relevant failure risk is: Wrong subnet masks or interface directions can permit unrelated clients or cause expected traffic to miss the rule. Validate with: Test clients from included and excluded subnets reach only the intended destinations and policy hit counters align.
For the observed situation (A test machine in an adjacent subnet can access a resource reserved for a separate tenant), the most specific acceptance evidence is: Test clients from included and excluded subnets reach only the intended destinations and policy hit counters align. It validates the recommended response: Maintain accurate address objects and interface pairings so firewall policies select the intended source and destination networks. This addresses the documented risk: Wrong subnet masks or interface directions can permit unrelated clients or cause expected traffic to miss the rule.

Domain controller event collection for fsso (2.4) addresses another technical failure: Uncollected security logon events leave user identity mappings missing even when LDAP connectivity works. The case states: A test machine in an adjacent subnet can access a resource reserved for a separate tenant. The most direct paired action and test is: Maintain accurate address objects and interface pairings so firewall policies select the intended source and destination networks.
IP pool source nat address selection (2.2) would demonstrate or implement: An exhausted or misassigned translation pool can prevent sessions or violate source-IP allowlisting at a partner. This case instead tests Address objects and policy scope; the choice measures or changes another part of the system.
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 Address objects and policy scope; this alternative does not provide the matching intervention and separate acceptance evidence.
