A Company Is Building a Software as a Service Application

question 43

Multiple Choice

A company is building a software as a service application. As part of the new user sign-on workflow, a Python script invokes the CreateTable operation using the Amazon DynamoDB API.

• A) Add an allow statement for the dynamodb:PutItem action in a policy attached to the role used by the application creating the table.
• B) Set the StreamEnabled property of the StreamSpecification parameter to true, then call PutItem.
• C) Change the application to call DescribeTable periodically until the TableStatus is ACTIVE, then call PutItem.
