D. dynamodb:UpdateItem, dynamodb:GetItem, and dynamodb:PutItem Here's why: dynamodb:GetItem: This permission allows the Lambda function to retrieve an item from DynamoDB. dynamodb:UpdateItem: This permission allows the Lambda function to update the attributes of an item in DynamoDB. dynamodb:PutItem: This permission allows the Lambda function to create a new item if it doesn't already exist in the DynamoDB table.

D is the correct answer.

D is correct

x A: as delete is not required. Plus Put item is not required, update lets you create a new item if it doesn't already exist B: meets requirements. DescribeTable helps provide a list of attributes that can be used to update. x C: put not required; getrecords does not exist x D: put not required.

UpdateItem: Edits an existing item's attributes https://docs.aws.amazon.com/amazondynamodb/latest/APIReference/API_UpdateItem.html GetItem: retrieves attributes from the Thread table https://docs.aws.amazon.com/amazondynamodb/latest/APIReference/API_GetItem.html#API_GetItem_Examples PutItem: Creates a new item, or replaces an old item with a new item. https://docs.aws.amazon.com/amazondynamodb/latest/APIReference/API_PutItem.html

PutItem is to CREATE new item or replace old item with new item GetItem is to retrieve an item UpdateItem so to update the attributes Hence answer D
