Question 1180
At Oakmont Biotechnology, the FortiGate 7.6 security administration team encounters the following authorized operational case: two site-to-site IPsec tunnels terminate on the same failing ISP despite being labeled primary and backup. They need a defensible FortiOS configuration, diagnosis, validation or prevention decision. Which recurring review is most relevant to the same root risk?
Explanation
Correct Answer
Track transport diversity and avoid false redundancy assumptions. This recurring practice addresses redundant vpn split provider design because two logical tunnel interfaces sharing one upstream circuit do not protect against that circuit failure. It reinforces the supported change to use independent permitted underlays or peer paths and verify resilience across failure domains rather than relying on an unrelated periodic audit.
Incorrect Answers
Test rekey behavior during peer software changes reduces recurrence of ipsec security association lifetime, rather than the observed redundant vpn split provider design issue. The relevant preventive control for Oakmont Biotechnology is: Track transport diversity and avoid false redundancy assumptions. This distinction matters because two logical tunnel interfaces sharing one upstream circuit do not protect against that circuit failure.
Record VPN tunnel type before reusing policy templates reduces recurrence of policy-based versus route-based vpn, rather than the observed redundant vpn split provider design issue. The relevant preventive control for Oakmont Biotechnology is: Track transport diversity and avoid false redundancy assumptions. This distinction matters because two logical tunnel interfaces sharing one upstream circuit do not protect against that circuit failure.
Revalidate MTU when adding additional tunnel encapsulation reduces recurrence of ipsec vpn mtu and fragmentation, rather than the observed redundant vpn split provider design issue. The relevant preventive control for Oakmont Biotechnology is: Track transport diversity and avoid false redundancy assumptions. This distinction matters because two logical tunnel interfaces sharing one upstream circuit do not protect against that circuit failure.
