Question 25
Domain 3: Cloud Technology and ServicesA solutions architect needs to design an AWS-based application that can both deliver application messages between components and send alerts to subscribers when important events occur. Which AWS service category is most appropriate to evaluate for this requirement?
Correct answer: C
Explanation
Use AWS messaging and notifications services when a solution must deliver messages between components and send alerts or notifications to recipients. — 05-AWS_Core_Services.md
Why each option is right or wrong
A. Compute services for running application code and processing workloads
Compute services run workloads; they are not the primary category for delivering messages and sending alerts.
B. Storage services for retaining files, objects, and long-term data
Storage services retain data; they are not intended to send notifications and deliver application messages.
C. Messaging and notifications services for message delivery and event alerts
The requirement explicitly includes delivering messages and sending alerts and notifications. The source material states that the appropriate service choice is the category used for delivering messages and for sending alerts and notifications.
D. Database services for structured records and transactional queries
Database services store and query records; they do not primarily provide alerting and message delivery functions.
