3. C. Use the credentials to make the API call.
4. D. Store the API credentials in a local code variabl
5. E. Push the code to a secure Git repositor
6. F. Use the local code variable at runtime to make the API call.
7. G. Store the API credentials as an object in a private Amazon S3 bucke
8. H. Restrict access to the S3 object by using IAM policie
9. I. Retrieve the API credentials at runtime by using the AWS SD
10. J. Use the credentials to make the API call.
11. K. Store the API credentials in an Amazon DynamoDB tabl
12. L. Restrict access to the table by using resource-based policie
13. M. Retrieve the API credentials at runtime by using the AWS SD
14. N. Use the credentials to make the API call.

2. B. Install and run the X-Ray daemon on the on-premises servers to capture and relay the data to the X-Ray service.
3. C. Capture incoming requests on-premises and configure an AWS Lambda function to pull, process, and relay relevant data to X-Ray using the PutTraceSegments API call.
4. D. Capture incoming requests on-premises and configure an AWS Lambda function to pull, process, and relay relevant data to X-Ray using the PutTelemetryRecords API call.

Correct Answer: B

A company wants to deploy and maintain static websites on AWS. Each website's source code is hosted in one of several version control systems, including AWS CodeCommit, Bitbucket, and GitHub.
The company wants to implement phased releases by using development, staging, user acceptance testing, and production environments in the AWS Cloud. Deployments to each environment must be started by code merges on the relevant Git branch. The company wants to use HTTPS for all data exchange. The company needs a solution that does not require servers to run continuously.
Which solution will meet these requirements with the LEAST operational overhead?

1. A. Host each website by using AWS Amplify with a serverless backen
2. B. Conned the repository branches that correspond to each of the desired environment
3. C. Start deployments by merging code changes to a desired branch.
4. D. Host each website in AWS Elastic Beanstalk with multiple environment
5. E. Use the EB CLI to link each repository branc
6. F. Integrate AWS CodePipeline to automate deployments from version control code merges.
7. G. Host each website in different Amazon S3 buckets for each environmen
8. H. Configure AWS CodePipeline to pull source code from version contro
9. I. Add an AWS CodeBuild stage to copy source code to Amazon S3.
10. J. Host each website on its own Amazon EC2 instanc
11. K. Write a custom deployment script to bundle each website's static asset
12. L. Copy the assets to Amazon EC2. Set up a workflow to run the script when code is merged.

Correct Answer: A
