1Z0-1072-25 Question 119
Single answerYou have deployed a web application in two different Oracle Cloud Infrastructure regions. Your goal is to ensure that users are automatically directed to the region offering the best response time. If one region becomes unavailable, user traffic should fail over to the other region. Which Traffic Management steering policy type should you configure in OCI DNS to best meet these requirements?
- A
Create a Weighted Steering Policy to distribute traffic evenly across both regions
- B
Create a Failover Steering Policy with the primary endpoint in the first region and secondary endpoint in the second region
- C
Create a Latency Steering Policy that directs users to the region with the best response times
- D
Create a Geolocation Steering Policy to explicitly route traffic from specific continents to each region
Show answer and explanation
Correct answer: C
Explanation
Latency Steering Policies in OCI DNS allow dynamic routing decisions based on actual response times from each region. This ensures that users are directed to the fastest, healthy endpoint, and if one region becomes unavailable, traffic can fail over to the other region for continued service. For more details, refer to the Oracle Cloud Infrastructure DNS documentation on Traffic Management Steering Policies (https://docs.oracle.com/en-us/iaas/Content/DNS/Concepts/trafficmanagement.htm).
- A. Incorrect.
Option 1 (Weighted Steering Policy): Weighted steering distributes traffic according to assigned weights (for example, 70% to one region, 30% to another), not based on real-time response times or availability. This doesn�t fulfill the requirement of always routing users to the fastest region and automatically failing over if the primary region is down, making this option incorrect.
- B. Incorrect.
Option 2 (Failover Steering Policy): While failover steering does direct traffic to a primary region and then fail over to a secondary region if needed, it does not dynamically route users to whichever region is currently providing the fastest response. It only switches to the secondary site if the primary fails, so it doesn�t meet the requirement of always optimizing for response times.
- C. Correct.
Option 3 (Latency Steering Policy): This policy is designed to measure real-time latency to various endpoints and direct clients to the region showing the lowest latency. If an endpoint becomes unreachable or its latency increases significantly, requests can be routed to another healthy endpoint. This approach fulfills both the requirement for best response times and automatic failover, making it the correct answer.
- D. Incorrect.
Option 4 (Geolocation Steering Policy): Geolocation steering routes traffic based on the client� geographic location (for example, Europe vs. North America). It doesn�t dynamically optimize for the best response time and does not provide automatic failover across regions�hence not suitable for this scenario.
