A developer supports an application that accesses data in an Amazon DynamoDB table. One of the item attributes is expiration Date 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 DeleteItem 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 EventBridge (Amazon CloudWatch Events) scheduled rule to invoke the Lambda functions. Use the DeleteItem 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.

A development team wants to build a continuous integration/continuous delivery (CI/CD) pipeline. The team is using AWS CodePipeline to automate the code build and deployment. The team wants to store the program code to prepare for the CI/CD pipeline.
Which AWS service should the team use to store the program code?

A. AWS CodeDeploy
B. AWS CodeArtifact
C. AWS CodeCommit
D. Amazon CodeGuru

A developer has created an AWS Lambda function that is written in Python. The Lambda function reads data from objects in Amazon S3 and writes data to an Amazon DynamoDB table.
The function is successfully invoked from an S3 event notification when an object is created. However, the function fails when it attempts to write to the DynamoDB table.
What is the MOST likely cause of this issue?

A. The Lambda function's concurrency limit has been exceeded.
B. The DynamoDB table requires a global secondary index (GSI) to support writes.
C. The Lambda function does not have IAM permissions to write to DynamoDB.
D. The DynamoDB table is not running in the same Availability Zone as the Lambda function.

A developer is writing an application that stores data in an Amazon DynamoDB table by using the Putltem API operation. The table has a partition key of streamID and has a sort key of seqID. The developer needs to make sure that the PutItem invocation does not overwrite the existing partition key and sort key.
Which condition expression will maintain the uniqueness of the partition key and the sort key?

A.

B.

C.

D.

A company has deployed a single-page application on AWS. The application stores assets in an Amazon S3 bucket. The application has an Amazon CloudFront distribution that is configured with the S3 bucket as the origin. Amazon API Gateway APIs access AWS Lambda functions that store information in an Amazon DynamoDB table. The application ingests a payload that includes 20 fields of sensitive data.
Which combination of steps should a developer take to protect the sensitive data through its entire lifecycle in AWS? (Choose two.)

A. Create a Lambda@Edge function to encrypt data when CloudFront processes a client request. Configure the distribution to invoke the Lambda@Edge function when the origin request event occurs.
B. Generate an AWS Key Management Service (AWS KMS) customer managed key that Lambda@Edge can use.
C. Create an SSL/TLS certificate in AWS Certificate Manager (ACM). Associate the certificate with the Network Load Balancer.
D. Set up a Network Load Balancer for API Gateway private integrations.
E. Store the data in the S3 bucket by using server-side encryption with Amazon S3 managed encryption keys (SSE-S3). Transfer the encrypted data from the S3 bucket to the DynamoDB table.

A developer wants to use AWS CodeDeploy to deploy an Amazon Elastic Container Service (Amazon ECS) service.
What are the MINIMUM properties required in the 'resources' section of the AppSpec file for CodeDeploy to deploy the ECS service successfully?

A. name, alias, currentversion, and targetversion
B. TaskDefinition, ContainerName, and PlatformVersion
C. TaskDefinition, ContainerName, and ContainerPort
D. name, currentversion, NetworkConfiguration, and PlatformVersion

A developer is creating an application. New users of the application must be able to create an account and register by using their own social media accounts.
Which AWS service or resource should the developer use to meet these requirements?

A. IAM role
B. Amazon Cognito identity pools
C. Amazon Cognito user pools
D. AWS Directory Service

A research company has a website that is used once each day to perform scientific calculations based on inputs that are submitted through a webpage. The calculations are CPU intensive. An AWS Lambda function performs the calculations once each day. Users occasionally receive errors because of Lambda function timeouts.
Which change will reduce the Lambda function's runtime duration?

A. Configure Lambda to run the function on an Amazon EC2 burstable instance type.
B. Configure Lambda to run the function on an Amazon EC2 instance type that is recommended for high performance computing (HPC) workloads.
C. Configure Lambda to run the function with a larger reserved concurrency value.
D. Configure Lambda to run the function with a larger memory value.

A company has a serverless application that uses AWS Lambda functions and AWS Systems Manager parameters to store configuration data. The company moves the Lambda functions inside the VPC and into private subnets. The Lambda functions are now producing errors in their attempts to access Systems Manager parameters.
Which solution will allow the Lambda functions to access Systems Manager parameters inside the VPC?

A. Configure security groups to allow access to Systems Manager.
B. Create an interface VPC endpoint for Systems Manager.
C. Use an Internet gateway from inside the VPC.
D. Create a gateway VPC endpoint for Systems Manager.

A developer is storing many objects in a single Amazon S3 bucket. The developer needs to optimize the S3 bucket for high request rates.
How should the developer store the objects to meet this requirement?

A. Store the objects by using S3 Intelligent-Tiering.
B. Store the objects at the root of the S3 bucket.
C. Store the objects by using object key names distributed across multiple prefixes.
D. Store each object with an object tag named "prefix" that contains a unique value.
