1Z0-1072-25 Question 117
Single answerYour company has deployed a web application to two Oracle Cloud Infrastructure (OCI) regions. The goal is to direct 80% of client requests to the primary region and 20% to the secondary region using OCI� weighted round robin DNS steering. After configuring your DNS zone and creating the necessary Traffic Management Steering Policy, you notice that requests are still evenly distributed among both regions. Which action would best resolve this issue so that requests match the intended 80/20 split?
- A
Create a Failover Steering Policy instead of Weighted Round Robin, as Failover policies directly manage traffic percentages.
- B
Configure separate health checks for each endpoint in the Traffic Management Steering Policy to ensure status-based routing.
- C
Use Weighted Round Robin Steering Policy with appropriate endpoint weights and ensure you have published the changes to the OCI DNS zone.
- D
Enable DNS Security (DNSSEC) on the zone to enforce weighted distribution logic.
Show answer and explanation
Correct answer: C
Explanation
In OCI, Weighted Round Robin Steering Policies allow fine-grained distribution of traffic across multiple endpoints by assigning weights to each IP or hostname. To achieve the desired 80/20 split, ensure the steering policy is configured with the correct weights (e.g., 80 for the primary region and 20 for the secondary) and that any changes are published to the DNS zone. Health checks and DNSSEC are important for security and high availability but do not directly control the traffic distribution ratio. Refer to the Oracle Cloud Infrastructure DNS Traffic Management documentation for further guidance on creating, configuring, and publishing Weighted Round Robin Steering Policies.
- A. Incorrect.
Incorrect. Failover Steering Policies only route traffic to the secondary endpoint when the primary is down; they do not distribute traffic by percentages.
- B. Incorrect.
Incorrect. Health checks are crucial for marking endpoints as healthy or unhealthy, but merely enabling health checks does not control traffic distribution by weight. They ensure failover rather than split distribution.
- C. Correct.
Correct. The Weighted Round Robin Steering Policy must have properly configured weights (for example, 80 and 20) for the two endpoints. After making changes, the steering policy must be published to the OCI DNS zone so the changes take effect.
- D. Incorrect.
Incorrect. DNSSEC protects the integrity of DNS records but does not influence the ratio of traffic distribution. Enabling DNSSEC alone will not change how requests are split between endpoints.
