A developer is designing a serverless application with two AWS Lambda functions to process photos.One Lambda function stores objects in an Amazon S3 bucket and stores the associated metadata in an Amazon DynamoDB table.The other Lambda function fetches the objects from the S3 bucket by using the metadata from the DynamoDB table.Both Lambda functions use the same Python library to perform complex computations and are approaching the quota for the maximum size of zipped deployment packages.What should the developer do to reduce the size of the Lambda deployment packages with the LEAST operational overhead?Read More →

A developer has built an application running on AWS Lambda using AWS Serverless Application Model (AWS SAM).What is the correct sequence of steps to successfully deploy the application?Read More →

A developer is adding a feature to a client-side application so that users can upload videos to an Amazon S3 bucket.What is the MOST secure way to give the application the ability to write files to the S3 bucket?Read More →

A developer needs to deploy the code for a new application on an AWS Lambda function.The application needs a dependency file that is 500 MB to run the business logic.Which solution will meet these requirements?Read More →

A media company wants to test its web application more frequently.The company deploys the application by using a separate AWS CloudFormation stack for each environment.The same CloudFormation template is deployed to each stack as the application progresses through the development lifecycle.A developer needs to build an automated alert for the quality assurance (QA) team.The developer wants the alert to occur for new deployments in the final pre-production environment.Which solution will moot these requirements?Read More →

A developer is creating a solution to track an account’s Amazon S3 buckets over time.The developer has created an AWS Lambda function that will run on a schedule.The function will list the account’s S3 buckets and will store the list in an Amazon DynamoDB table.The developer receives a permissions error when the developer runs the function with the AWSLambdaBasicExecutionRole AWS managed policy.Which combination of permissions should the developer use to resolve this error? (Choose two.)Read More →

A company is building a cloud solution to analyze customer demographic data.The data includes personally identifiable information (PII) such as full names, street addresses, and financial records.A developer is configuring a source Amazon DynamoDB table with a DynamoDB stream.The developer is writing an AWS Lambda function that will ingest the demographic data from the DynamoDB stream.perform analytics, and write results to a separate DynamoDB table.The application must log important AWS API workflow events for monitoring purposes, but the application must expose the PII.Which combination of actions should the developer take to log the LARGEST amount of AWS API operational information without exposing the PII? (Choose two.)Read More →

A developer has built an application that inserts data into an Amazon DynamoDB table.The table is configured to use provisioned capacity.The application is deployed on a burstable nano Amazon EC2 instance.The application logs show that the application has been failing because of a ProvisionedThroughputExceededException error.Which actions should the developer take to resolve this issue? (Choose two.)Read More →

A developer is working on a serverless project.Initial testing shows that a cold start takes about 8 seconds on average for AWS Lambda functions.Which actions should the developer take to reduce the cold start time? (Choose two.)Read More →

A developer is using an AWS Lambda function to generate avatars for profile pictures that are uploaded to an Amazon S3 bucket.The Lambda function is automatically invoked for profile pictures that are saved under the /original/ S3 prefix.The developer notices that some pictures cause the Lambda function to time out.The developer wants to implement a fallback mechanism by using another Lambda function that resizes the profile picture.Which solution will meet these requirements with the LEAST development effort?Read More →
