Which combination of permissions should the developer use to resolve this error? (Choose two.)
Question 25
A company is adding items to an Amazon DynamoDB table from an AWS Lambda function that is written in Python.

Which solution meets these requirements with MINIMUM code changes?
Question 26
A developer is writing an AWS Lambda function. The developer wants to log key events that occur during the Lambda function and include a unique identifier to associate the events with a specific function invocation. Which of the following will help the developer accomplish this objective?
Question 27
A company experienced partial downtime during the last deployment of a new application. AWS Elastic Beanstalk split the environment's Amazon EC2 instances into batches and deployed a new version one batch at a time after taking them out of service. Therefore, full capacity was not maintained during deployment. The developer plans to release a new version of the application, and is looking for a policy that will maintain full capacity and minimize the impact of the failed deployment. Which deployment policy should the developer use?
Question 28
A company is providing services to many downstream consumers. Each consumer may connect to one or more services.

Question 29
When a Developer tries to run an AWS CodeBuild project, it raises an error because the length of all environment variables exceeds the limit for the combined maximum of characters. What is the recommended solution?
Question 30
A Development team decides to adopt a continuous integration/continuous delivery (CI/CD) process using AWS CodePipeline and AWS CodeCommit for a new application. However, management wants a person to review and approve the code before it is deployed to production. How can the Development team add a manual approver to the CI/CD pipeline?
