Question 180
At Lakeside Research, the cybersecurity services team administers FortiGate-based protection for campus labs and private research infrastructure under requirements for identity-aware segmentation and evidence retention. An independent validation is requested for: Remote workers cannot access sanctioned private applications because their FortiSASE tenant has not completed supported client onboarding. Which observed outcome BEST demonstrates that the intended correction works?
Explanation
Correct Answer
A managed test user appears as onboarded and accesses only the corporate application approved by the FortiSASE policy. This outcome validates the intended correction for: Remote workers cannot access sanctioned private applications because their FortiSASE tenant has not completed supported client onboarding. The associated approved corrective action is: Complete supported FortiSASE endpoint or user onboarding with the required identity and device registration controls. The Lakeside Research reviewer can therefore distinguish observable protection from an untested configuration claim.
Incorrect Answers
A controlled failure of one heartbeat path leaves the cluster in its intended single-primary state with the surviving heartbeat healthy. This would verify a separate corrective action: Design redundant dedicated heartbeat connections and appropriate heartbeat monitoring according to the supported HA topology. That separate change addresses: An FGCP cluster uses a single heartbeat link attached to an unstable switch, creating split-brain risk during a link outage. It does not validate the current Lakeside Research issue: Remote workers cannot access sanctioned private applications because their FortiSASE tenant has not completed supported client onboarding. The relevant acceptance evidence is: A managed test user appears as onboarded and accesses only the corporate application approved by the FortiSASE policy.
A controlled loss of the monitored primary link triggers the expected cluster transition without changing unrelated firewall policies. This would verify a separate corrective action: Configure HA interface monitoring for the required upstream links and test the designed failover behavior. That separate change addresses: A FortiGate active-passive HA pair keeps serving through a failed primary WAN port because the critical interface is not monitored. It does not validate the current Lakeside Research issue: Remote workers cannot access sanctioned private applications because their FortiSASE tenant has not completed supported client onboarding. The relevant acceptance evidence is: A managed test user appears as onboarded and accesses only the corporate application approved by the FortiSASE policy.
The expected controlled event appears in a repeatable search with timestamps correlating to the external incident clock. This would verify a separate corrective action: Correct the log source, time zone and search time range before concluding that the network event was never logged. That separate change addresses: Investigators see an apparent gap in the FortiGate GUI log viewer because its time filter excludes the incident period. It does not validate the current Lakeside Research issue: Remote workers cannot access sanctioned private applications because their FortiSASE tenant has not completed supported client onboarding. The relevant acceptance evidence is: A managed test user appears as onboarded and accesses only the corporate application approved by the FortiSASE policy.
