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 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 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 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 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 a legacy application that is hosted on-premises.Other applications hosted on AWS depend on the on-premises application for proper functioning.In case of any application errors, the developer wants to be able to use Amazon CloudWatch to monitor and troubleshoot all applications from one place.How can the developer accomplish this?Read More →

A developer is writing a new AWS Serverless Application Model (AWS SAM) template with a new AWS Lambda function.The Lambda function runs complex code.The developer wants to test the Lambda function with more CPU power.What should the developer do to meet this requirement?Read More →

A developer is receiving HTTP 400: ThrottlingException errors intermittently when calling the Amazon CloudWatch API.When a call fails, no data is retrieved.What best practice should first be applied to address this issue?Read More →

A developer is using an AWS CodeCommit repository to store source code for an application.The developer is using an AWS CodePipeline pipeline to deploy the application.The pipeline does not start automatically and must be started manually when a deployment is needed.The developer needs to configure the pipeline to start automatically.Which solution meets this requirement with the LEAST delay?Read More →

A company configures an Amazon S3 bucket to deliver S3 object events to Amazon EventBridge (Amazon CloudWatch Events).An EventBridge rule invokes an AWS Lambda function for each object event that is received from the S3 bucket.A developer is working on a new version of the Lambda function.To ensure that the new Lambda function works as expected, the developer must run a repeatable test that uses realistic S3 bucket object events.The developer must minimize the amount of code and infrastructure that are required to support the test.Which solution will meet these requirements?Read More →
