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
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.)
BD
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 Putltem 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?
C
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?
C
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?
B
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
A company has developed a new serverless application using AWS Lambda functions that will be deployed using the AWS Serverless Application Model (AWS SAM) CLI.
Which step should the developer complete prior to deploying the application?
C
A developer is working on an ecommerce website. The developer wants to review server logs without logging in to each of the application servers individually. The website runs on multiple Amazon EC2 instances, is written in Python, and needs to be highly available.
How can the developer update the application to meet these requirements with MINIMUM changes?
B
A company needs an event-management platform to accept registrations for an upcoming event. The platform must perform a single invocation of an existing AWS Lambda function 10 minutes after a user completes a new account registration.
Which solution will meet these requirements?
B
How would a developer notify users when a new item is written to a DynamoDB table without affecting the provisioned throughput?
A
