Question 90
At Bayfield University, the FortiGate 7.6 security administration team encounters the following authorized operational case: FortiAnalyzer and its managed firewalls display a security incident with misleading time ordering. They need a defensible FortiOS configuration, diagnosis, validation or prevention decision. What root condition most directly explains the described FortiGate symptom?
Explanation
Correct Answer
Clock drift and mismatched timezone interpretation can distort event correlation. The mechanism is relevant because the stated ntp alignment across fortianalyzer incident concerns the actual selected path, policy, identity or inspection state. The appropriate response is to synchronize all logging devices with reliable time sources and verify timezone display assumptions; verify it through this observed condition: the same test transaction has consistent normalized timestamps across both platforms.
Incorrect Answers
Losing heartbeat communication can prevent members from confirming each other's HA state explains a different situation, fgcp ha heartbeat cabling, where two FortiGates configured as a cluster both appear active after a heartbeat link fails. It does not account for the specific observed ntp alignment across fortianalyzer condition at Bayfield University. The decisive mechanism here is: Clock drift and mismatched timezone interpretation can distort event correlation.
Shared cluster management access does not automatically provide independent reachability to each member explains a different situation, ha reserved management interface, where operations cannot manage the standby appliance directly while the primary remains active in a cluster. It does not account for the specific observed ntp alignment across fortianalyzer condition at Bayfield University. The decisive mechanism here is: Clock drift and mismatched timezone interpretation can distort event correlation.
A valid route entry is ineffective when the layer-two next-hop neighbor cannot be resolved explains a different situation, arp resolution failure, where a firewall route targets a next hop but the outbound FortiGate cannot resolve that neighbor on its attached VLAN. It does not account for the specific observed ntp alignment across fortianalyzer condition at Bayfield University. The decisive mechanism here is: Clock drift and mismatched timezone interpretation can distort event correlation.
