Question 130
At Granite SaaS, the platform network security team administers FortiGate-based protection for a hosted business application and remote administrator fleet under requirements for per-tenant access restrictions and reliable telemetry. Following the approved change, the team must validate: A FortiGate uplink alternates between up and down because connected switch settings disagree on speed or physical media characteristics. Which observed outcome BEST demonstrates that the intended correction works?
Explanation
Correct Answer
Interface flaps and error counters stop increasing and a sustained approved connectivity test remains stable. This outcome validates the intended correction for: A FortiGate uplink alternates between up and down because connected switch settings disagree on speed or physical media characteristics. The associated approved corrective action is: Check interface status, error counters, optics and supported speed or negotiation settings at both ends of the link. The Granite SaaS reviewer can therefore distinguish observable protection from an untested configuration claim.
Incorrect Answers
A test policy change and traffic event arrive on the intended syslog collector with the expected device identification. This would verify a separate corrective action: Configure the supported remote syslog destination, transport and required event selection consistently at both endpoints. That separate change addresses: A distributed security operation relies on syslog messages from FortiGate but the configured collector port and delivery protocol differ. It does not validate the current Granite SaaS issue: A FortiGate uplink alternates between up and down because connected switch settings disagree on speed or physical media characteristics. The relevant acceptance evidence is: Interface flaps and error counters stop increasing and a sustained approved connectivity test remains stable.
A policy trace identifies the actual ingress and egress virtual interfaces and authorized traffic matches the intended rule. This would verify a separate corrective action: Inventory the virtual FortiGate interface mapping and bind policies and zones to the real cloud-connected NICs. That separate change addresses: A cloud firewall rollout uses the same interface identifiers as a hardware FortiGate and creates policy matches against nonexistent virtual ports. It does not validate the current Granite SaaS issue: A FortiGate uplink alternates between up and down because connected switch settings disagree on speed or physical media characteristics. The relevant acceptance evidence is: Interface flaps and error counters stop increasing and a sustained approved connectivity test remains stable.
A controlled denied flow is found in the appropriate traffic log with matching source, destination and decision context. This would verify a separate corrective action: Search the corresponding traffic, event and relevant UTM log categories using consistent time, addresses and policy identifiers. That separate change addresses: An analyst filters only security-event logs while investigating a denied connection and incorrectly concludes no firewall policy evaluated the flow. It does not validate the current Granite SaaS issue: A FortiGate uplink alternates between up and down because connected switch settings disagree on speed or physical media characteristics. The relevant acceptance evidence is: Interface flaps and error counters stop increasing and a sustained approved connectivity test remains stable.
