1Z0-1072-25 Question 129
Single answerYour organization runs an application across two Oracle Cloud Infrastructure regions: Phoenix (primary site) and Ashburn (secondary site). You want to route all traffic to Phoenix during normal operations, but automatically fail over to Ashburn if the Phoenix site becomes unreachable. You have decided to use a Traffic Management Steering Policy in OCI to achieve this. Which steering type should you configure to fulfill this requirement?
- A
Weighted Steering
- B
Failover Steering
- C
Geolocation Steering
- D
Load Balancer Steering
Show answer and explanation
Correct answer: B
Explanation
Failover Steering Policies in OCI Traffic Management are specifically designed to handle active-passive configurations. By setting the primary endpoint as 'live' and the secondary endpoint as 'standby' with health checks, all traffic is routed to Phoenix (primary) by default, automatically switching to Ashburn (secondary) if Phoenix becomes unhealthy. Refer to OCI documentation on 'DNS Traffic Management' and the 'Failover Steering Policy' configuration for best practices and additional details.
- A. Incorrect.
Weighted Steering allows you to distribute a percentage of traffic to different endpoints. Although you can simulate partial failover by assigning weights, it is not the recommended approach for an active-passive scenario because weighted steering does not straightforwardly switch all traffic to a secondary site upon failure.
- B. Correct.
Failover Steering is designed precisely for active-passive scenarios: all traffic goes to the primary endpoint until it becomes unavailable. At that point, traffic is automatically routed to the secondary endpoint. This meets the requirement of routing traffic to Phoenix by default and failing over to Ashburn if Phoenix is unreachable.
- C. Incorrect.
Geolocation Steering directs traffic based on the geographic location of the clients. While you can configure multiple locations, it does not inherently handle a simple primary-to-secondary failover scenario unless you assign overlapping geolocation rules with complex configurations. It's not the ideal match for the described requirement.
- D. Incorrect.
Load Balancer Steering is not an officially recognized steering policy type in OCI Traffic Management. Load balancing is available through OCI Load Balancer resources, but that is separate from Traffic Management Steering Policies. Hence, this option does not directly achieve the failover objective.
