WHY A IS False? |
CONCEPT: Amazon SQS(Amazon Simple Queue Service) |
Amazon SQS is a fully managed message queuing service that enables you to decouple and scale microservices, distributed systems, and serverless applications.Here we require a notification service not a message queue service like SQS.

WHY B IS False? |
CONCEPT: Amazon Simple Workflow Service (Amazon SWF) |
SWF makes it easy to build applications that use Amazon's cloud to coordinate work across distributed components. Amazon SWF gives you full control over implementing tasks and coordinating them without worrying about underlying complexities such as tracking their progress and maintaining their state. Therefore it is a workflow orchestration service and it is not used for publishing messages to mobile app users. |
WHY C IS True? |
CONCEPT: Amazon Simple Notification Service (Amazon SNS) |
Amazon SNS is a fully managed messaging service for both application-to-application (A2A) and application-to-person (A2P) communication. With Amazon SNS, you have the ability to send push notification messages directly to apps on mobile devices. Push notification messages sent to a mobile endpoint can appear in the mobile app as message alerts, badge updates, or even sound alerts. You send push notification messages to both mobile devices and desktops using supported push notification services.

WHY D IS False? |
CONCEPT: Amazon CloudWatch Events |
Amazon CloudWatch Events delivers a near real-time stream of system events that describe changes in Amazon Web Services (AWS) resources. Hence, CloudWatch Events will not be able to send notifications to mobile app users.
NEW SERVICE ALERT: Amazon EventBridge is the preferred way to manage your events. CloudWatch Events and EventBridge are the same underlying service and API, but EventBridge provides more features. Changes you make in either CloudWatch or EventBridge will appear in each console.

Short Trick |
1." push notification" which redirects us to Amazon SNS as it is a basic notification service used to send push notification messages to both mobile devices and desktops.
