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.
get
post
pull
push
Explanations:
“Get” is used to retrieve data, but does not relate to resolving conflicts or notifying devices about new data.
“Post” is used to send data to a server but does not specifically address conflict resolution or push synchronization features in Amazon Cognito.
“Pull” refers to retrieving data, but does not correspond to sending notifications about data changes or resolving conflicts in Amazon Cognito.
“Push” is the correct answer, as it refers to Amazon Cognito’s ability to send silent notifications to devices, notifying them about the availability of new data.
I design that the answer is:
push
