A company stores all personally identifiable information (PII) in an Amazon DynamoDB table named PII in Account A.Developers are working on an application that is running on Amazon EC2 instances in Account B.The application in Account B requires access to the PII table.An administrator in Account A creates an IAM role named AccessPII that has permission to access the PII table.The administrator also creates a trust policy that specifies Account B as a principal that can assume the role.Which combination of steps should the developers take in Account B to allow their application to access the PII table? (Choose two.)Read More →

A developer has an application that asynchronously invokes an AWS Lambda function.The developer wants to store messages that resulted in failed invocations of the Lambda function so that the application can retry the call later.What should the developer do to accomplish this goal with the LEAST operational overhead?Read More →
