Question 2

A DevOps engineer has automated a web service deployment by using AWS CodePipeline with the following steps:

1) An AWS CodeBuild project compiles the deployment artifact and runs unit tests.

2) An AWS CodeDeploy deployment group deploys the web service to Amazon EC2 instances in the staging environment.

3) A CodeDeploy deployment group deploys the web service to EC2 instances in the production environment.

The quality assurance (QA) team requests permission to inspect the build artifact before the deployment to the production environment occurs. The QA team wants to run an internal penetration testing tool to conduct manual tests. The tool will be invoked by a REST API call.

Which combination of actions should the DevOps engineer take to fulfill this request? (Choose two.)

Options:

A.

Insert a manual approval action between the test actions and deployment actions of the pipeline.

B.

Modify the buildspec.yml file for the compilation stage to require manual approval before completion.

C.

Update the CodeDeploy deployment groups so that they require manual approval to proceed.

D.

Update the pipeline to directly call the REST API for the penetration testing tool.

E.

Update the pipeline to invoke an AWS Lambda function that calls the REST API for the penetration testing tool.

Question 3

A company needs to implement failover for its application. The application includes an Amazon CloudFront distribution and a public Application Load Balancer (ALB) in an AWS Region. The company has configured the ALB as the default origin for the distribution.

After some recent application outages, the company wants a zero-second RTO. The company deploys the application to a secondary Region in a warm standby configuration. A DevOps engineer needs to automate the failover of the application to the secondary Region so that HTTP GET requests meet the desired RTO.

Which solution will meet these requirements?

Options:

A.

Create a second CloudFront distribution that has the secondary ALB as the default origin. Create Amazon Route 53 alias records that have a failover policy and Evaluate Target Health set to Yes for both CloudFront distributions. Update the application to use the new record set.

B.

Create a new origin on the distribution for the secondary ALB. Create a new origin group. Set the original ALB as the primary origin. Configure the origin group to fail over for HTTP 5xx status codes. Update the default behavior to use the origin group.

C.

Create Amazon Route 53 alias records that have a failover policy and Evaluate Target Health set to Yes for both ALBs. Set the TTL of both records to 0. Update the distribution ' s origin to use the new record set.

D.

Create a CloudFront function that detects HTTP 5xx status codes. Configure the function to return a 307 Temporary Redirect error response to the secondary ALB if the function detects 5xx status codes. Update the distribution ' s default behavior to send origin responses to the function.
