A company runs a critical application on Amazon Elastic Container Service (Amazon ECS) by using Amazon EC2 instances. The company needs to migrate the application to Amazon ECS on AWS Fargate. A developer is configuring Fargate and the ECS capacity providers to make the change.
Which solution will meet these requirements with the LEAST downtime during migration?

  1. Use the PutClusterCapacityProviders API operation to associate the ECS cluster with the FARGATE and FARGATE_SPOT capacity provider strategies. Use FARGATE as Provider 1 with a base value. Use FARGATE_SPOT as Provider 2 for failover.
  2. Use the CreateCapacityProvider API operation to associate the ECS cluster with the FARGATE and FARGATE_SPOT capacity provider strategies. Use FARGATE as Provider 1 with a base value. Use FARGATE_SPOT as Provider 2 for failover.
  3. Use the PutClusterCapacityProviders API operation to associate the ECS cluster with the FARGATE and FARGATE_SPOT capacity provider strategies. Use FARGATE_SPOT as Provider 1 with a base value. Use FARGATE as Provider 2 for failover.
  4. Use the CreateCapacityProvider API operation to associate the ECS cluster with the FARGATE and FARGATE_SPOT capacity provider strategies. Use FARGATE_SPOT as Provider 1 with a base value. Use FARGATE as Provider 2 for failover.

Answer(s): A



A company has a web application that is hosted on AWS. The application is behind an Amazon CloudFront distribution. A developer needs a dashboard to monitor error rates and anomalies of the CloudFront distribution as frequently as possible.
Which combination of steps should the developer take to meet these requirements? (Choose two.)

  1. Stream the CloudFront distribution logs to an Amazon S3 bucket. Detect anomalies and error rates by using Amazon Athena.
  2. Enable real-time logs on the CloudFront distribution. Create a data stream in Amazon Kinesis Data Streams.
  3. Set up Amazon Kinesis Data Streams to send the logs to Amazon OpenSearch Service by using an AWS Lambda function. Make a dashboard in OpenSearch Dashboards.
  4. Stream the CloudFront distribution logs to Amazon Kinesis Data Firehose.
  5. Set up Amazon Kinesis Data Firehose to send the logs to AWS CloudTrail. Create CloudTrail metrics, alarms, and dashboards.

Answer(s): B,C



A developer creates an Amazon DynamoDB table. The table has OrderID as the partition key and NumberOfItemsPurchased as the sort key. The data type of the partition key and the sort key is Number.
When the developer queries the table, the results are sorted by NumberOfItemsPurchased in ascending order. The developer needs the query results to be sorted by NumberOfItemsPurchased in descending order.
Which solution will meet this requirement?

  1. Create a local secondary index (LSI) on the NumberOfItemsPurchased sort key.
  2. Change the sort key from NumberOfItemsPurchased to NumberOfItemsPurchasedDescending.
  3. In the Query operation, set the ScanIndexForward parameter to false.
  4. In the Query operation, set the KeyConditionExpression parameter to false.

Answer(s): C



A developer needs to use a code template to create an automated deployment of an application onto Amazon EC2 instances. The template must be configured to repeat deployment, installation, and updates of resources for the application. The template must be able to create identical environments and roll back to previous versions.
Which solution will meet these requirements?

  1. Use AWS Amplify for automatic deployment templates. Use a traffic-splitting deployment to copy any deployments. Modify any resources created by Amplify, if necessary.
  2. Use AWS CodeBuild for automatic deployment. Upload the required AppSpec file template. Save the appspec.yml file in the root directory folder of the revision. Specify the deployment group that includes the EC2 instances for the deployment.
  3. Use AWS CloudFormation to create an infrastructure template in JSON format to deploy the EC2 instances. Use CloudFormation helper scripts to install the necessary software and to start the application. Call the scripts directly from the template.
  4. Use AWS AppSync to deploy the application. Upload the template as a GraphQL schema. Specify the EC2 instances for deployment of the application. Use resolvers as a version control mechanism and to make any updates to the deployments.

Answer(s): C



A developer has a continuous integration and continuous delivery (CI/CD) pipeline that uses AWS CodeArtifact and AWS CodeBuild. The build artifacts are between 0.5 GB and 1.5 GB in size. The builds happen frequently and retrieve many dependencies from CodeArtifact each time.
The builds have been slow because of the time it takes to transfer dependencies. The developer needs to improve build performance by reducing the number of dependencies that are retrieved for each build.
Which solution will meet this requirement?

  1. Specify an Amazon S3 cache in CodeBuild. Add the S3 cache folder path to the buildspec.yaml file for the build project.
  2. Specify a local cache in CodeBuild. Add the CodeArtifact repository name to the buildspec.yaml file for the build project.
  3. Specify a local cache in CodeBuild. Add the cache folder path to the buildspec.yaml file for the build project.
  4. Retrieve the buildspec.yaml file directly from CodeArtifact. Add the CodeArtifact repository name to the buildspec.yaml file for the build project.
