    DVA-C02 Questions and Answers

    Question # 1

    A company uses AWS X-Ray to monitor a serverless application. The components of the application have different request rates. The user interactions and transactions are important to trace, but they are low in volume. The background processes such as application health checks, polling, and connection maintenance generate high volumes of read-only requests.

    Currently, the default X-Ray sampling rules are universal for all requests. Only the first request per second and some additional requests are recorded. This setup is not helping the company review the requests based on service or request type.

    A developer must configure rules to trace requests based on service or request properties. The developer must trace the user interactions and transactions without wasting effort recording minor background tasks.

    Which solution will meet these requirements?

    A.

    Disable sampling for high-volume read-only requests. Sample at a lower rate for all requests that handle user interactions or transactions.

    B.

    Disable sampling and trace all requests for requests that handle user interactions or transactions. Sample high-volume read-only requests at a higher rate.

    C.

    Disable sampling and trace all requests for requests that handle user interactions or transactions. Sample high-volume read-only requests at a lower rate.

    D.

    Disable sampling for high-volume read-only requests. Sample at a higher rate for all requests that handle user interactions or transactions.

    Question # 2

    A developer warns to add request validation to a production environment Amazon API Gateway API. The developer needs to test the changes before the API is deployed to the production environment. For the lest the developer will send test requests to the API through a testing tool.

    Which solution will meet these requirements with the LEAST operational overhead?

    A.

    Export the existing API to an OpenAPI file. Create a new API Import the OpenAPI file Modify the new API to add request validation. Perform the tests Modify the existing API to add request validation. Deploy the existing API to production.

    B.

    Modify the existing API to add request validation. Deploy the updated API to a new API Gateway stage Perform the tests Deploy the updated API to the API Gateway production stage.

    C.

    Create a new API Add the necessary resources and methods including new request validation. Perform the tests Modify the existing API to add request validation. Deploy the existing API to production.

    D.

    Clone the exiting API Modify the new API lo add request validation. Perform the tests Modify the existing API to add request validation Deploy the existing API to production.

    Question # 3

    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.

    Question # 4

    A developer supports an application that accesses data in an Amazon DynamoDB table. One of the item attributes is expirationDate in the timestamp format. The application uses this attribute to find items, archive them, and remove them from the table based on the timestamp value

    The application will be decommissioned soon, and the developer must find another way to implement this functionality. The developer needs a solution that will require the least amount of code to write.

    Which solution will meet these requirements?

    A.

    Enable TTL on the expirationDate attribute in the table. Create a DynamoDB stream. Create an AWS Lambda function to process the deleted items. Create a DynamoDB trigger for the Lambda function.

    B.

    Create two AWS Lambda functions one to delete the items and one to process the items Create a DynamoDB stream Use the Deleteltem API operation to delete the items based on the expirationDate attribute Use the GetRecords API operation to get the items from the DynamoDB stream and process them

    C.

    Create two AWS Lambda functions, one to delete the items and one to process the items. Create an Amazon EventBndge scheduled rule to invoke the Lambda Functions Use the Deleteltem API operation to delete the items based on the expirationDate attribute. Use the GetRecords API operation to get the items from the DynamoDB table and process them.

    D.

    Enable TTL on the expirationDate attribute in the table Specify an Amazon Simple Queue Service (Amazon SQS> dead-letter queue as the target to delete the items Create an AWS Lambda function to process the items

    Question # 5

    A company is building an application to accept data from customers. The data must be encrypted at rest and in transit.

    The application uses an Amazon API Gateway API that resolves to AWS Lambda functions. The Lambda functions store the data in an Amazon Aurora MySQL DB cluster. The application worked properly during testing.

    A developer configured an Amazon CloudFront distribution with field-level encryption that uses an AWS Key Management Service (AWS KMS) key. After the configuration of the distribution, the application behaved unexpectedly. All the data in the database changed from plaintext to ciphertext.

    The developer must ensure that the data is not stored in the database as the ciphertext from the CloudFront field-level encryption.

    Which solution will meet this requirement?

    A.

    Change the CloudFront Viewer protocol policy from "HTTP and HTTPS" to "HTTPS only."

    B.

    Add a Lambda function that uses the KMS key to decrypt the data fields before saving the data to the database.

    C.

    Enable encryption on the DB cluster by using the same KMS key that is used in CloudFront.

    D.

    Request and deploy a new SSL certificate to use with the CloudFront distribution.
