Amazon AWS Certified Developer - Associate Sample Questions (Q684-Q689):

NEW QUESTION # 684
A company is developing a serverless application by using AWS Lambda functions. One of the Lambda functions needs to access an Amazon RDS DB instance. The DB instance is in a private subnet inside a VPC.
The company creates a role that includes the necessary permissions to access the DB instance.
The company then assigns the role to the Lambda function. A developer must take additional action to give the Lambda function access to the DB instance.
What should the developer do to meet these requirements?

A. Assign a public IP address to the DB instance. Modify the security group of the DB instance to allow inbound traffic from the IP address of the Lambda function.
B. Set up an AWS Direct Connect connection between the Lambda function and the DB instance.
C. Configure an Amazon CloudFront distribution to create a secure connection between the Lambda function and the DB instance.
D. Configure the Lambda function to connect to the private subnets in the VPC. Add security group rules to allow traffic to the DB instance from the Lambda function.

Answer: D

NEW QUESTION # 685
A developer is creating an application that will give users the ability to store photos from their cellphones in the cloud. The application needs to support tens of thousands of users. The application uses an Amazon API Gateway REST API that is integrated with AWS Lambda functions to process the photos. The application stores details about the photos in Amazon DynamoDB.
Users need to create an account to access the application. In the application, users must be able to upload photos and retrieve previously uploaded photos. The photos will range in size from 300 KB to 5 MB.
Which solution will meet these requirements with the LEAST operational overhead?

A. Create a users table in DynamoDB. Use the table to manage user accounts. Create a Lambda authorizer that validates user credentials against the users table. Integrate the Lambda authorizer with API Gateway to control access to the API. Use the Lambda function to store the photos in Amazon S3. Store the object's S3 key as par of the photo details in the DynamoDB table. Retrieve previously uploaded photos by querying DynamoDB for the S3 key.
B. Create an IAM user for each user of the application during the sign-up process. Use IAM authentication to access the API Gateway API. Use the Lambda function to store the photos in Amazon S3. Store the object's S3 key as part of the photo details in the DynamoDB table. Retrieve previously uploaded photos by querying DynamoDB for the S3 key.
C. Use Amazon Cognito user pools to manage user accounts. Create an Amazon Cognito user pool authorizer in API Gateway to control access to the API. Use the Lambda function to store the photos in Amazon S3. Store the object's S3 key as part of the photo details in the DynamoDB table. Retrieve previously uploaded photos by querying DynamoDB for the S3 key.
D. Use Amazon Cognito user pools to manage user accounts. Create an Amazon Cognito user pool authorizer in API Gateway to control access to the API. Use the Lambda function to store the photos and details in the DynamoDB table. Retrieve previously uploaded photos directly from the DynamoDB table.

Answer: C

Explanation:
Explanation
Amazon Cognito user pools is a service that provides a secure user directory that scales to hundreds of millions of users. The developer can use Amazon Cognito user pools to manage user accounts and create an Amazon Cognito user pool authorizer in API Gateway to control access to the API. The developer can use the Lambda function to store the photos in Amazon S3, which is a highly scalable, durable, and secure object storage service. The developer can store the object's S3 key as part of the photo details in the DynamoDB table, which is a fast and flexible NoSQL database service. The developer can retrieve previously uploaded photos by querying DynamoDB for the S3 key and fetching the photos from S3. This solution will meet the requirements with the least operational overhead.

NEW QUESTION # 686
A developer is creating a serverless application that uses an AWS Lambda function. The developer will use AWS CloudFormation to deploy the application. The application will write logs to Amazon CloudWatch Logs. The developer has created a log group in a CloudFormation template for the application to use. The developer needs to modify the CloudFormation template to make the name of the log group available to the application at runtime.
Which solution will meet this requirement?

A. Pass the log group's name to the application in the user data section of the CloudFormation template.
B. Use the CloudFormation template's Mappings section to specify the log group's name for the application.
C. Pass the log group's Amazon Resource Name (ARN) as an environment variable to the Lambda function.
D. Use the AWS::Include transform in CloudFormation to provide the log group's name to the application.

Answer: C

NEW QUESTION # 687
A developer is creating an application that uses an AWS Lambda function to transform and load data from an Amazon S3 bucket. When the developer tests the application, the developer finds that some invocations of the Lambda function are slower than others.
The developer needs to update the Lambda function to have predictable invocation durations that run with low latency. Any initialization activities, such as loading libraries and instantiating clients, must run during allocation time rather than during actual function invocations.
Which combination of steps will meet these requirements? (Select TWO.)

A. Deploy changes, and publish a new version of the Lambda function.
B. Use the $LATEST version of the Lambda function.
C. Configure provisioned concurrency for the Lambda function to have the necessary number of execution environments.
D. Create a schedule group in Amazon EventBridge Scheduler to invoke the Lambda function.
E. Configure reserved concurrency for the Lambda function to have the necessary number of execution environments.

Answer: C,E

NEW QUESTION # 688
A company wants to automate part of its deployment process. A developer needs to automate the process of checking for and deleting unused resources that supported previously deployed stacks but that are no longer used.
The company has a central application that uses the AWS Cloud Development Kit (AWS CDK) to manage all deployment stacks. The stacks are spread out across multiple accounts. The developer's solution must integrate as seamlessly as possible within the current deployment process.
Which solution will meet these requirements with the LEAST amount of configuration?

A. In the central AWS CDK, write a handler function in the code that uses AWS SDK calls to check for and delete unused resources. Create an API in AWS Amplify. Use the API to attach the function code to an AWS Lambda function and to invoke the Lambda function when the deployment stack runs.
B. In the central AWS CDK application, write a handler function in the code that uses AWS SDK calls to check for and delete unused resources. Create an AWS CDK custom resource. Use the custom resource to attach the function code to an AWS Lambda function and to invoke the Lambda function when the deployment stack runs.
C. In the central AWS CDK application, write a handler function in the code that uses AWS SDK calls to check for and delete unused resources. Create an AWS CloudFormation template from a JSON file. Use the template to attach the function code to an AWS Lambda function and to invoke the Lambda function when the deployment stack runs.
D. In the AWS Lambda console, write a handler function in the code that uses AWS SDK calls to check for and delete unused resources. Create an AWS CDK custom resource. Use the custom resource to import the Lambda function into the stack and to invoke the Lambda function when the deployment stack runs.

Answer: B
