A Developer has written code for an application and wants to share it with other Developers on the team to receive feedback. The shared application code needs to be stored long-term with multiple versions and batch change tracking.
Which AWS service should the Developer use?

A. AWS CodeBuild
B. Amazon S3
C. AWS CodeCommit
D. AWS Cloud9

A Developer must allow guest users without logins to access an Amazon Cognito-enabled site to view files stored within an Amazon S3 bucket.
How should the Developer meet these requirements?

A. Create a blank user ID in a user pool, add to the user group, and grant access to AWS resources.
B. Create a new identity pool, enable access to authenticated identities, and grant access to AWS resources.
C. Create a new user pool, enable access to authenticated identifies, and grant access to AWS resources.
D. Create a new user pool, disable authentication access, and grant access to AWS resources.

A Developer is preparing a deployment package using AWS CloudFormation. The package consists of two separate templates: one for the infrastructure and one for the application. The application has to be inside the VPC that is created from the infrastructure template.
How can the application stack refer to the VPC created from the infrastructure template?

A. Use the Ref function to import the VPC into the application stack from the infrastructure template.
B. Use the export flag in the infrastructure template, and then use the Fn::ImportValue function in the application template.
C. Use the DependsOn attribute to specify that the application instance depends on the VPC in the application template.
D. Use the Fn::GetAtt function to include the attribute of the VPC in the application template.

A company provides APIs as a service and commits to a service level agreement (SLA) with all its users. To comply with each SLA, what should the company do?

A. Enable throttling limits for each method in Amazon API Gateway
B. Create a usage plan for each user and request API keys to access the APIs
C. Enable API rate limiting in Amazon Cognito for each user
D. Enable default throttling limits for each stage after deploying the APIs

A Developer registered an AWS Lambda function as a target for an Application Load Balancer (ALB) using a CLI command. However, the Lambda function is not being invoked when the client sends requests through the ALB.
Why is the Lambda function not being invoked?

A. A Lambda function cannot be registered as a target for an ALB.
B. A Lambda function can be registered with an ALB using AWS Management Console only.
C. The permissions to invoke the Lambda function are missing.
D. Cross-zone is not enabled on the ALB.

A Developer is trying to monitor an application’s status by running a cron job that returns 1 if the service is up and 0 if the service is down. The Developer created code that uses an AWS CLI put-metric-alarm command to publish the custom metrics to Amazon CloudWatch and create an alarm. However, the Developer is unable to create an alarm as the custom metrics do not appear in the CloudWatch console.
What is causing this issue?

A. Sending custom metrics using the CLI is not supported.
B. The Developer needs to use the put-metric-data command.
C. The Developer must use a unified CloudWatch agent to publish custom metrics.
D. The code is not running on an Amazon EC2 instance.

A Developer needs to create an application that supports Security Assertion Markup Language (SAML) and Facebook authentication. It must also allow access to AWS services, such as Amazon DynamoDB.
Which AWS service or feature will meet these requirements with the LEAST amount of additional coding?

A. AWS AppSync
B. Amazon Cognito identity pools
C. Amazon Cognito user pools
D. Amazon Lambda@Edge

A Developer is building a serverless application using AWS Lambda and must create a REST API using an HTTP GET method.
What needs to be defined to meet this requirement? (Choose two.)

A. A Lambda@Edge function
B. An Amazon API Gateway with a Lambda function
C. An exposed GET method in an Amazon API Gateway
D. An exposed GET method in the Lambda function
E. An exposed GET method in Amazon Route 53

A Development team decides to adopt a continuous integration/continuous delivery (CI/CD) process using AWS CodePipeline and AWS CodeCommit for a new application. However, management wants a person to review and approve the code before it is deployed to production.
How can the Development team add a manual approver to the CI/CD pipeline?

A. Use AWS SES to send an email to approvers when their action is required. Develop a simple application that allows approvers to accept or reject a build. Invoke an AWS Lambda function to advance the pipeline when a build is accepted.
B. If approved, add an approved tag when pushing changes to the CodeCommit repository. CodePipeline will proceed to build and deploy approved commits without interruption.
C. Add an approval step to CodeCommit. Commits will not be saved until approved.
D. Add an approval action to the pipeline. Configure the approval action to publish to an Amazon SNS topic when approval is required. The pipeline execution will stop and wait for an approval.

A Developer has written an application that runs on Amazon EC2 instances and generates a value every minute. The Developer wants to monitor and graph the values generated over time without logging in to the instance each time.
Which approach should the Developer use to achieve this goal?

A. Use the Amazon CloudWatch metrics reported by default for all EC2 instances. View each value from the CloudWatch console.
B. Develop the application to store each value in a file on Amazon S3 every minute with the timestamp as the name.
C. Publish each generated value as a custom metric to Amazon CloudWatch using available AWS SDKs.
D. Store each value as a variable and add the variable to the list of EC2 metrics that should be reported to the Amazon CloudWatch console.
