Question 30
A FortiOS 7.6 team examines: A branch adds a second client subnet and the previous DHCP range overlaps it. 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 branch adds a second client subnet and the previous DHCP range overlaps it. The targeted administrative response is: Configure FortiGate DHCP service on the intended client-facing interface with a valid address range, gateway and DNS options. The relevant failure risk is: An overlapping DHCP pool or incorrectly scoped server can assign clients unreachable addresses or gateways. Validate with: A test client on the approved VLAN receives the intended lease, gateway and DNS servers without duplicate assignments.
For the observed situation (A branch adds a second client subnet and the previous DHCP range overlaps it), the most specific acceptance evidence is: A test client on the approved VLAN receives the intended lease, gateway and DNS servers without duplicate assignments. It validates the recommended response: Configure FortiGate DHCP service on the intended client-facing interface with a valid address range, gateway and DNS options. This addresses the documented risk: An overlapping DHCP pool or incorrectly scoped server can assign clients unreachable addresses or gateways.
Incorrect Answers
Local and remote log storage selection (1.2) would demonstrate or implement: A controlled permitted and denied flow appears at the approved retained logging destination with correct timestamps. This case instead tests Fortigate dhcp service and subnet scope; the choice measures or changes another part of the system.
High cpu and process-focused diagnosis (1.4) would demonstrate or implement: Restarting a device or disabling inspection without finding the resource consumer can hide a repeatable overload. The required paired action and test concerns Fortigate dhcp service and subnet scope; a passing result for this alternative could leave that requirement unresolved.
Fortigate cnf versus vm operating models (1.5) addresses another technical failure: Assuming a managed CNF has identical configuration and operating-system control to a FortiGate VM creates support gaps. The paired-answer requirement concerns Fortigate dhcp service and subnet scope; this alternative does not provide the matching intervention and separate acceptance evidence.
