DVA-C02 Exam Question 2

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?

A.Use AWS Amplify for automatic deployment templates. Use a traffic-splitting deployment to copy any deployments. Modify any resources created by Amplify, if necessary.

B.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.

C.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.

D.Use AWS CloudFormation to create an infrastructure template in JSON format to deploy the EC2 instances. Use Cloud Formation helper scripts to install the necessary software and to start the application. Call the scripts directly from the template.

B.Create separate AWS AppConfig feature flags for both groups of users. Configure the flags to target
15% of users.

C.Create an AWS AppConfig feature flag. Define a variant for the new feature, and create a rule to target
15% of users.

D.Use AWS AppConfig to create a feature flag without variants. Implement a custom traffic-splitting mechanism in the application code.

DVA-C02 Exam Question 5

A developer wants to store information about movies. Each movie has a title, release year, and genre. The movie information also can include additional properties about the cast and production crew. This additional information is inconsistent across movies. For example, one movie might have an assistant director, and another movie might have an animal trainer.
The developer needs to implement a solution to support the following use cases:
For a given title and release year, get all details about the movie that has that title and release year.
For a given title, get all details about all movies that have that title.
For a given genre, get all details about all movies in that genre.
Which data store configuration will meet these requirements?

A.Create an Amazon DynamoDB table. Configure the table with a primary key that consists of the title as the partition key and the release year as the sort key. Create a global secondary index that uses the genre as the partition key and the title as the sort key.

B.Create an Amazon DynamoDB table. Configure the table with a primary key that consists of the genre as the partition key and the release year as the sort key. Create a global secondary index that uses the title as the partition key.

C.On an Amazon RDS DB instance, create a table that contains columns for title, release year, and genre.
Configure the title as the primary key.

D.On an Amazon RDS DB instance, create a table where the primary key is the title and all other data is encoded into JSON format as one additional column.
