Selected Answer: C

"If you use dynamodb:Attributes, you must specify the names of all of the primary key and index key attributes for the table and any secondary indexes that are listed in the policy. Otherwise, DynamoDB can't use these key attributes to perform the requested action." that makes sense, can't update user_name without user_id

A is the correct answer. The Leading key allows users to access only the items where the partition key value matches their user ID. And as Attribute value we set user_name because we want that the userID is able to update only his username

The question "Which set of conditions should be added in the policy attached to the role for the dynamodb:PutItem API call?" shouldn't ask about UpdateItem? Is it a typo or is it ok? If it is all right, then why?
