- A
Amazon Simple Notification Service (SNS)
Amazon SNS is a fully managed pub/sub messaging service that can deliver messages to a variety of subscribers, including mobile push notifications and email. It is the correct choice for this requirement.
- B
Amazon Simple Queue Service (SQS)
Why wrong: Amazon SQS is a message queue service used for decoupling application components. It does not support sending push notifications or emails directly; it only stores messages and allows consumers to poll them from a queue.
- C
Amazon Simple Email Service (SES)
Why wrong: Amazon SES is a managed service for sending email only. It does not support mobile push notifications, so it does not meet the requirement to send alerts to both mobile devices and email.
- D
Amazon Pinpoint
Why wrong: Amazon Pinpoint is a managed marketing and engagement service that can send push, email, and SMS. However, it is designed for targeted campaigns and audience segmentation, making it more complex and heavier than needed for simple system alerts. Amazon SNS is the simpler and more appropriate fully managed service for straightforward event notifications.
Quick Answer
The answer is Amazon Simple Notification Service (SNS). This is the correct choice because SNS is a fully managed pub/sub messaging service that natively supports multiple delivery protocols, including push notifications to mobile devices via services like Apple Push Notification Service and Firebase Cloud Messaging, as well as email alerts through SMTP or HTTP endpoints, all from a single service without requiring separate infrastructure for each channel. On the AWS Certified Cloud Practitioner CLF-C02 exam, this question tests your understanding of managed messaging services and their integration with mobile and email endpoints; a common trap is confusing SNS with Amazon Simple Queue Service (SQS), which handles message queuing rather than push delivery. Remember the memory tip: SNS “Sends Notifications to Subscribers” across multiple channels, while SQS “Stores Queued Messages” for polling.
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 company runs a microservices application on AWS. It needs to send real-time alerts to mobile devices via push notifications and to administrators via email whenever a critical event occurs. The solution must be a fully managed service that supports both delivery channels without requiring separate infrastructure for each. Which AWS service should the company use?

Correct answer & explanation
Amazon Simple Notification Service (SNS)
Amazon SNS is a fully managed pub/sub messaging service that supports multiple delivery protocols, including push notifications to mobile devices (via Apple Push Notification Service, Firebase Cloud Messaging, etc.) and email (via SMTP or HTTP endpoints). This allows the company to send real-time alerts through both channels from a single service without provisioning separate infrastructure for each.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Amazon Simple Email Service (SES)
Why it's wrong here
Amazon SES is a managed service for sending email only. It does not support mobile push notifications, so it does not meet the requirement to send alerts to both mobile devices and email.

Amazon Pinpoint
Why it's wrong here
Amazon Pinpoint is a managed marketing and engagement service that can send push, email, and SMS. However, it is designed for targeted campaigns and audience segmentation, making it more complex and heavier than needed for simple system alerts. Amazon SNS is the simpler and more appropriate fully managed service for straightforward event notifications.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse Amazon Pinpoint (a marketing and analytics service) with Amazon SNS (a simple pub/sub notification service), but the question explicitly asks for a fully managed service that supports both push notifications and email without separate infrastructure — SNS fits this requirement directly, while Pinpoint is designed for targeted campaigns and user segmentation, not simple event-driven alerts.
Detailed technical explanation
How to think about this question
SNS uses a topic-based pub/sub model where publishers send messages to a topic, and subscribers receive messages via chosen protocols (e.g., HTTP, email, SMS, mobile push). Under the hood, SNS handles message fan-out, retries, and delivery status logging, and it integrates with AWS Lambda for custom processing. In a real-world scenario, a microservices application can publish a critical event to an SNS topic, which then fans out to an email subscription for administrators and a mobile push subscription for on-call engineers simultaneously.
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.
