- A
Amazon SES
Why wrong: SES is for email delivery only — it doesn't support mobile push notifications.
- B
Amazon Pinpoint
Why wrong: Pinpoint is a marketing communications service for targeted campaigns. For simple real-time push notifications, SNS is the standard foundational service.
- C
Amazon SNS
SNS directly integrates with Apple APNs, Google FCM, and Amazon ADM to deliver push notifications to mobile devices at scale.
- D
AWS AppSync
Why wrong: AppSync is a managed GraphQL API service — it doesn't deliver mobile push notifications.

CLF-C02 Cloud Technology and Services Practice Question
This CLF-C02 practice question tests your understanding of cloud technology and services. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A developer wants to send real-time notifications to mobile app users when new content is available. Which AWS service enables push notifications to iOS and Android devices?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Amazon SNS
Amazon SNS (Simple Notification Service) is the correct choice because it provides a fully managed pub/sub messaging service that supports push notifications to mobile endpoints via platform application endpoints for iOS (APNs) and Android (FCM). It enables real-time delivery of messages directly to mobile apps without requiring polling or additional infrastructure.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates may confuse Amazon Pinpoint as the only service for push notifications due to its marketing focus, but Amazon SNS is the core service for direct programmatic push notification delivery to mobile devices.
Detailed technical explanation
How to think about this question
Amazon SNS uses platform application endpoints to integrate with Apple Push Notification service (APNs) for iOS and Firebase Cloud Messaging (FCM) for Android. When a developer publishes a message to an SNS topic, the service automatically delivers the notification to all subscribed endpoints, including mobile devices, using the appropriate protocol and authentication credentials. A subtle behavior is that SNS supports message filtering and delivery retries, but developers must ensure the mobile app registers its device token with SNS via a platform endpoint ARN to receive notifications.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
TExam Day Tips
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A cloud solutions architect for a retail company is evaluating services for a new workload. The correct answer here reflects best practice for the specific scenario described — not a general cloud recommendation. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Cloud exam questions reward reading the constraint carefully: the same technology can be right or wrong depending on the use case.
