AWS Certified Solutions Architect – Professional — Question 91

By default, Amazon Cognito maintains the last-written version of the data. You can override this behavior and resolve data conflicts programmatically.
In addition, push synchronization allows you to use Amazon Cognito to send a silent notification to all devices associated with an identity to notify them that new data is available.

Answer options

Correct answer: D

Explanation

The correct answer is D because push synchronization specifically refers to the act of sending notifications to devices about new data. Options A (get), B (post), and C (pull) do not describe the process of sending notifications; instead, they refer to data retrieval and submission actions.
