Question 20
A firewall has an equal-cost pair of routes but one next-hop path is unreachable, and session steering must be validated instead of relying on configuration labels alone. Which observable result BEST demonstrates that the intended FortiGate security or connectivity requirement is satisfied?
Explanation
Correct Answer
The preferred route is selected under normal conditions and documented alternates take over consistently when the primary path is unusable. This is the operational validation outcome rather than merely an enabled setting. Two equal prefixes are not necessarily equally preferred if their administrative distances or priority differ; ECMP can distribute sessions rather than guaranteeing one preferred path. Scenario: A firewall has an equal-cost pair of routes but one next-hop path is unreachable, and session steering must be validated instead of relying on configuration labels alone.
Incorrect Answers
Approved sessions recover over a permitted secondary member according to policy while unexpected fallback links remain excluded. This result would test SD-WAN implicit rules, failover decisions and session persistence but does not demonstrate the desired FortiGate outcome here. Verify instead: The preferred route is selected under normal conditions and documented alternates take over consistently when the primary path is unusable. Scenario: A firewall has an equal-cost pair of routes but one next-hop path is unreachable, and session steering must be validated instead of relying on configuration labels alone.
Traffic uses the alternative route when the monitored upstream path fails, and the preferred path returns without oscillating under the configured hold-down policy. This result would test Link monitoring and static route failover triggers but does not demonstrate the desired FortiGate outcome here. Verify instead: The preferred route is selected under normal conditions and documented alternates take over consistently when the primary path is unusable. Scenario: A firewall has an equal-cost pair of routes but one next-hop path is unreachable, and session steering must be validated instead of relying on configuration labels alone.
The intended applications traverse approved security policy and selected SD-WAN members with correct translation and bidirectional return traffic. This result would test SD-WAN interactions with firewall policies and source-specific routes but does not demonstrate the desired FortiGate outcome here. Verify instead: The preferred route is selected under normal conditions and documented alternates take over consistently when the primary path is unusable. Scenario: A firewall has an equal-cost pair of routes but one next-hop path is unreachable, and session steering must be validated instead of relying on configuration labels alone.
