Question 69

A company maintains a REST service using Amazon API Gateway and the API Gateway native API key validation. The company recently launched a new registration page, which allows users to sign up for the service. The registration page creates a new API key using CreateApiKey and sends the new key to the user. When the user attempts to call the API using this key. the user receives a 403 Forbidden error. Existing users are unaffected and can still call the API.

What code updates will grant these new users access to the API?

Options:

The createDeploymer.t method must be called so the API can be redeployed to include the newly created API key.

The updateAuthorizer method must be called to update the API's authorizer to include the newly created API key

The importApiKeys method must be called to import all newly created API keys into the current stage of the API.

The createUsagePlanKey method must be called to associate the newly created API key with the correct usage plan.

Question 70

A developer is configuring an applications deployment environment in AWS CodePipeine. The application code is stored in a GitHub repository. The developer wants to ensure that the repository package's unit tests run in the new deployment environment. The deployment has already set the pipeline's source provider to GitHub and has specified the repository and branch to use in the deployment.

When combination of steps should the developer take next to meet these requirements with the least the LEAST overhead' (Select TWO).

Options:

Create an AWS CodeCommt project. Add the repository package's build and test commands to the protects buildspec

Create an AWS CodeBuid project. Add the repository package's build and test commands to the projects buildspec

Create an AWS CodeDeploy protect. Add the repository package's build and test commands to the project's buildspec

Add an action to the source stage. Specify the newly created project as the action provider. Specify the build attract as the actions input artifact.

Add a new stage to the pipeline alter the source stage. Add an action to the new stage. Speedy the newly created protect as the action provider. Specify the source artifact as the action's input artifact.

Question 71

A company has an online web application that includes a product catalog. The catalog is stored in an Amazon S3 bucket that is named DOC-EXAMPLE-BUCKET. The application must be able to list the objects in the S3 bucket and must be able to download objects through an 1AM policy.

Which policy allows MINIMUM access to meet these requirements?

Options:

Option A

Option B

Option C

Option D

Question 72

A developer has designed an application to store incoming data as JSON files in Amazon S3 objects. Custom business logic in an AWS Lambda function then transforms the objects, and the Lambda function loads the data into an Amazon DynamoDB table. Recently, the workload has experienced sudden and significant changes in traffic. The flow of data to the DynamoDB table is becoming throttled.

The developer needs to implement a solution to eliminate the throttling and load the data into the DynamoDB table more consistently.

Which solution will meet these requirements?

Options:

Refactor the Lambda function into two functions. Configure one function to transform the data and one function to load the data into the DynamoDB table. Create an Amazon Simple Queue Service (Amazon SQS) queue in between the functions to hold the items as messages and to invoke the second function.

Turn on auto scaling for the DynamoDB table. Use Amazon CloudWatch to monitor the table's read and write capacity metrics and to track consumed capacity.

Create an alias for the Lambda function. Configure provisioned concurrency for the application to use.

Refactor the Lambda function into two functions. Configure one function to store the data in the DynamoDB table. Configure the second function to process the data and update the items after the data is stored in DynamoDB. Create a DynamoDB stream to invoke the second function after the data isstored.
