Question 640
A Security Gateway has active and backup external VPN interfaces. The primary next hop becomes unreachable during a maintenance test, but the gateway keeps trying that circuit. The cloud peer is otherwise healthy. The operator must distinguish this from a separate requirement to provide multi-link cloud IPsec interoperability on a supported fixed-address, non-ElasticXL R82 gateway. Which supported change follows from the actual evidence rather than that alternative hypothesis?
Explanation
Correct Answer
Availability probes help choose working links. This directly addresses the documented incident evidence.
Incorrect Answers
Enhanced Link Selection supports cloud IPsec redundancy without proprietary RDP, with DAIP and platform limits, but the current evidence calls for a different R82 operation.
Link Selection controls VPN interface and address selection; this does not resolve the observed condition.
VPN Link Selection can share VPN traffic across available links, yet that applies to define how VPN traffic is distributed across multiple usable links rather than the observed issue.
