1Z0-1072-25 Question 128
Single answerYou manage an e-commerce application running in two OCI regions: a primary deployment in Ashburn (US East) and a secondary deployment in Phoenix (US West) for redundancy. You need to route traffic to the secondary region only if the primary region becomes unavailable, ensuring uninterrupted service from a single domain name. Which type of OCI Traffic Management Steering Policy configuration best fulfills this requirement?
- A
Weighted Steering
- B
Failover Steering
- C
Geolocation Steering
- D
Latency Steering
Show answer and explanation
Correct answer: B
Explanation
Failover Steering Policies in OCI Traffic Management are designed to check the availability (health) of the designated primary endpoint. If the health check fails, traffic is transparently redirected to the secondary endpoint, ensuring business continuity. According to Oracle documentation, this approach is recommended when you want to maintain a single domain name but keep a fully functional standby deployment for high availability.
- A. Incorrect.
Weighted Steering is incorrect because it distributes traffic across endpoints based on assigned weights rather than failing over entirely if one endpoint is unavailable. It� typically used to direct a certain percentage of traffic to different regions but does not automatically switch all traffic upon a single endpoint failure.
- B. Correct.
Failover Steering is correct because it designates a primary endpoint and a secondary endpoint, automatically routing all traffic to the secondary site only if the health check for the primary site fails. This ensures an uninterrupted customer experience if the primary region becomes unavailable.
- C. Incorrect.
Geolocation Steering is incorrect because it routes users based on their geographic location, not on the availability of the primary endpoint. This policy type is typically used for compliance or performance-based requirements where users in specific regions must be directed to specific endpoints.
- D. Incorrect.
Latency Steering is incorrect because it routes traffic to the region with the lowest latency, not specifically to a secondary region only when the primary is down. While latency-based routing can improve performance, it does not guarantee failover in the strict sense.
