Question
An Insurance company has contracted you to help automate their application business continuity plan. They have the application running in eu-frankfurt-1 as the primary site and uk-london-1 as a disaster recovery site. Normally they have a DNS A record associated with the IP address of the primary endpoint In eu-frankfurt-1. In the event of a disaster, they use OCI DNS Zone Management to update the A record and replace it with the IP address of the endpoint In uk-london-1. How can you automate the failover process?
Options
- ACreate a Health Check that evaluates both regional endpoints. Create a Traffic Management Steering
- BCreate a Traffic Management Steering policy and attach it to a backend set with the backend servers
- CCreate a Traffic Management Steering policy with Load Balancer type and add both eu-frankfurt-1 and
- DProvision a Load Balancer in Frankfurt and associate it with the A record in DNS. Create a backend set

Explanation
Traffic Management Steering Policies: Failover policies allow you to prioritize the order in which you want answers served in a policy (for example, Primary and Secondary). Oracle Cloud Infrastructure Health Checks are leveraged to determine the health of answers in the policy. If the Primary Answer is determined to be unhealthy, DNS traffic will automatically be steered to the Secondary Answer. Load Balancer policies allow distribution of traffic across multiple endpoints. Endpoints can be assigned equal weights to distribute traffic evenly across the endpoints or custom weights may be assigned for ratio load balancing. Oracle Cloud Infrastructure Health Checks are leveraged to determine the health of the endpoint. DNS traffic will be automatically distributed to the other endpoints, if an endpoint is determined to be unhealthy. GEOLOCATION STEERING Geolocation steering policies distribute DNS traffic to different endpoints based on the location of the end user. Customers can define geographic regions composed of originating continent, countries or states/provinces (North America) and define a separate endpoint or set of endpoints for each region. ASN steering policies enable you to steer DNS traffic based on Autonomous System Numbers (ASN). DNS queries originating from a specific ASN or set of ASNs can be steered to a specified endpoint. IP PREFIX STEERING IP Prefix steering policies enable customers to steer DNS traffic based on the IP Prefix of the originating
