Question 180
A network team addresses this situation: An IPv6-only application cannot reach a legacy IPv4-only partner through direct native IPv6 routing. After the corrective action, which test or result BEST verifies that the problem is resolved?
Explanation
Correct Answer
A load balancer routes requests only to backends that satisfy its configured health checks. Verification of this result involves testing name resolution and bidirectional session flows to IPv4 targets.
Incorrect Answers
Compare policy enforcement and latency for branch and roaming clients. That check cannot demonstrate traffic delivery to healthy application targets.
Degrade one path and observe real-time traffic move to the healthy one. That check cannot demonstrate traffic delivery to healthy application targets.
Change contractor posture and verify denied access while approved apps remain reachable. That check cannot demonstrate traffic delivery to healthy application targets.
