Which combination of changes will meet this requirement with the LEAST operational overhead?
(Choose three.)
Deploy the API to multiple Regions. Configure Amazon Route 53 with custom domain names that route traffic to each Regional API endpoint. Implement a Route 53 multivalue answer routing policy.
Create a new KMS multi-Region customer managed key. Create a new KMS customer managed replica key in each in-scope Region.
Replicate the existing Secrets Manager secret to other Regions. For each in-scope Region’s replicated secret, select the appropriate KMS key.
Create a new AWS managed KMS key in each in-scope Region. Convert an existing key to a multi-Region key. Use the multi-Region key in other Regions.
Create a new Secrets Manager secret in each in-scope Region. Copy the secret value from the existing Region to the new secret in each in-scope Region.
Modify the deployment process for the Lambda function to repeat the deployment across in-scope Regions. Turn on the multi-Region option for the existing API. Select the Lambda function that is deployed in each Region as the backend for the multi-Region API.
I evaluate that the answer is:
Create a new KMS multi-Region customer managed key. Create a new KMS customer managed replica key in each in-scope Region.
I systematize that the answer is:
Create a new KMS multi-Region customer managed key. Create a new KMS customer managed replica key in each in-scope Region.
