1Z0-1067-25 Question 84
Select 2You operate a critical e-commerce application hosted in Oracle Cloud Infrastructure (OCI) with your primary region in Region A and a standby environment in Region B. You want to implement an automated failover strategy so that if Region A experiences an outage, end-user traffic is automatically routed to Region B. Which two steps must you perform to achieve this in OCI?
- A
A. Configure an OCI Health Check for the primary endpoint in Region A, and associate it with a Failover DNS Steering Policy.
- B
B. Deploy a single public Load Balancer across both Region A and Region B, and enable Global Traffic Management.
- C
C. Create a Failover DNS Steering Policy with your primary endpoint in Region A and a standby endpoint in Region B, then attach the Health Check to the policy.
- D
D. Update the application� route table in Region B to point back to the public subnet in Region A for minimal latency.
Show answer and explanation
Correct answers: A, C
Explanation
To implement automated failover in OCI, you must use DNS Traffic Management with a Failover Steering Policy and an associated Health Check on the primary endpoint. The Health Check monitors the application� health in the primary region; if it fails, the DNS steering policy routes traffic to the secondary region automatically. For more information on configuring DNS failover, refer to the Oracle Cloud Infrastructure DNS and Health Checks documentation.
- A. Correct.
A. Correct. Creating an OCI Health Check for your primary endpoint and associating it with a Failover DNS Steering Policy ensures the policy can detect an outage in Region A and reroute traffic automatically to Region B.
- B. Incorrect.
B. Incorrect. You cannot deploy a single public Load Balancer instance that spans multiple regions for automated failover in OCI. Each region needs its own load balancer, and global traffic steering uses DNS (not a single LB).
- C. Correct.
C. Correct. A Failover DNS Steering Policy with distinct primary and standby endpoints�combined with a configured Health Check�enables traffic redirection when the primary endpoint becomes unreachable.
- D. Incorrect.
D. Incorrect. Simply updating the route table in Region B to point back to Region A does not automate failover. You must use DNS-based traffic steering and health checks to achieve automatic rerouting when Region A is offline.
