Question 20
At Brookside Manufacturing, the plant network defense team administers FortiGate-based protection for industrial office networks and protected production systems under requirements for controlled inspection and limited access to process hosts. The security reviewer verifies a claimed fix for: A scheduled FortiOS change overwrites working settings and the team has no recoverable configuration from before the modification. Which observed outcome BEST demonstrates that the intended correction works?
Explanation
Correct Answer
A lab restore using the saved configuration reproduces intended interface, policy and routing settings without exposing backup credentials. This outcome validates the intended correction for: A scheduled FortiOS change overwrites working settings and the team has no recoverable configuration from before the modification. The associated approved corrective action is: Create and securely store a dated FortiGate configuration backup and document a verified restore path before the change window. The Brookside Manufacturing reviewer can therefore distinguish observable protection from an untested configuration claim.
Incorrect Answers
The VM reports the expected authorized license and supported capacity without a FortiGuard entitlement or initialization error. This would verify a separate corrective action: Verify the supported FortiGate VM licensing mode, required entitlement and instance resources before putting production traffic through it. That separate change addresses: A cloud FortiGate VM boots with reduced licensed capacity because its license or marketplace entitlement does not match the deployment model. It does not validate the current Brookside Manufacturing issue: A scheduled FortiOS change overwrites working settings and the team has no recoverable configuration from before the modification. The relevant acceptance evidence is: A lab restore using the saved configuration reproduces intended interface, policy and routing settings without exposing backup credentials.
A controlled permitted flow traverses the virtual FortiGate and the cloud route map shows the expected inspection hop. This would verify a separate corrective action: Map FortiGate VM interfaces to the cloud's supported networking and update the approved virtual network route tables for intended traffic flows. That separate change addresses: A FortiGate VM in a public cloud cannot receive routed inspection traffic because the virtual NIC and cloud route-table attachments are incorrect. It does not validate the current Brookside Manufacturing issue: A scheduled FortiOS change overwrites working settings and the team has no recoverable configuration from before the modification. The relevant acceptance evidence is: A lab restore using the saved configuration reproduces intended interface, policy and routing settings without exposing backup credentials.
A historical test event remains searchable over the required retention window without saturating the firewall's limited local storage. This would verify a separate corrective action: Choose an appropriate FortiAnalyzer, FortiGate Cloud or supported remote log destination and set a documented retention policy. That separate change addresses: Local FortiGate storage fills with detailed traffic logs and causes early loss of evidence needed for the regulatory retention period. It does not validate the current Brookside Manufacturing issue: A scheduled FortiOS change overwrites working settings and the team has no recoverable configuration from before the modification. The relevant acceptance evidence is: A lab restore using the saved configuration reproduces intended interface, policy and routing settings without exposing backup credentials.
