DOP-C02 Question 301

Select 3

Your company is running a multi-account AWS environment with centralized monitoring and incident handling. To ensure proactive responses to critical events, you need to design a solution that captures operational issues such as AWS service outages, unauthorized API calls, and scheduled maintenance updates, and routes them to your incident response team via an Amazon SNS topic. Which of the following combination of services can be used to achieve this?

A
Amazon EventBridge for capturing AWS Health events and routing them to an SNS topic
B
AWS CloudTrail for capturing unauthorized API calls and routing them to an SNS topic
C
AWS Health Dashboard for monitoring AWS service outages and sending notifications to an SNS topic
D
Amazon EventBridge for forwarding scheduled maintenance events from AWS Health to an SNS topic
E
AWS Config for monitoring compliance violations and triggering notifications to an SNS topic

Show answer and explanation

Correct answers: A, B, D

Explanation

A combination of Amazon EventBridge and AWS CloudTrail allows you to capture and process key operational events such as AWS Health updates, unauthorized API calls, and scheduled maintenance events. EventBridge is particularly effective for integrating with AWS Health and routing these events to an SNS topic, while CloudTrail is essential for tracking API activity, including security-related incidents. AWS Config and the AWS Health Dashboard are not suitable for this scenario as they do not directly generate or route the required events to SNS topics.

A. Correct.
Amazon EventBridge is ideal for capturing AWS Health events, such as service outages and maintenance updates, and routing them to an SNS topic for further processing. This is a correct option.
B. Correct.
AWS CloudTrail captures API activity, including unauthorized API calls. These events can be forwarded to an SNS topic for alerting. This is a correct option.
C. Incorrect.
The AWS Health Dashboard provides a visual interface for monitoring AWS service outages and maintenance events, but it does not directly integrate with SNS for notifications. This is an incorrect option.
D. Correct.
Amazon EventBridge can forward maintenance events from AWS Health to an SNS topic, enabling proactive communication for scheduled downtimes. This is a correct option.
E. Incorrect.
AWS Config is used for compliance and configuration monitoring, not for capturing operational events like AWS Health updates or unauthorized API calls. This is an incorrect option.

DOP-C02 Question 302

Select 3

Your organization uses multiple AWS services to monitor and respond to events across your infrastructure. Recently, a business-critical application experienced downtime, and your team wants to build an automated solution to detect AWS Health events, process them, and notify the appropriate teams via an internal messaging system. Which combination of services should you use to implement this solution?

A
Amazon EventBridge to capture AWS Health events and route them to an AWS Lambda function
B
AWS CloudTrail to directly trigger notifications for AWS Health events
C
AWS Lambda to process AWS Health events and send notifications to the internal messaging system
D
Amazon SNS to capture AWS Health events and forward them to EventBridge
E
AWS Health APIs to access detailed information about the AWS Health events

Show answer and explanation

Correct answers: A, C, E

Explanation

To implement an automated solution for detecting AWS Health events, EventBridge is used to capture and route the events. Lambda processes the events and can execute custom logic, such as sending notifications to the internal messaging system. AWS Health APIs provide detailed event information that can be queried to enhance the notifications. This combination ensures an automated, scalable approach to handling AWS Health events.

A. Correct.
Correct: Amazon EventBridge can capture AWS Health events in near real-time and route them to various targets like AWS Lambda for further processing.
B. Incorrect.
Incorrect: AWS CloudTrail logs API activity but does not directly support triggering notifications for AWS Health events. CloudTrail is better suited for auditing and governance purposes.
C. Correct.
Correct: AWS Lambda can process the events captured by EventBridge and execute custom logic, such as sending notifications to an internal messaging system.
D. Incorrect.
Incorrect: Amazon SNS is used for publishing messages to subscribers but does not natively capture AWS Health events. EventBridge should be used to capture such events.
E. Correct.
Correct: The AWS Health APIs provide detailed information about AWS Health events, which can be queried as part of the solution to enrich notifications.

DOP-C02 Question 303

You are designing an event-driven architecture for a real-time order processing system. When a new order is placed, it triggers an order validation process and a payment processing workflow simultaneously. You also want to ensure that a failure in either process does not affect the other and that events are processed asynchronously. Which combination of AWS services should you use to implement this architecture?

A
Amazon SNS and Amazon SQS
B
Amazon Kinesis Data Streams and AWS Lambda
C
Amazon EventBridge and Amazon SQS
D
AWS Step Functions and Amazon Kinesis Data Streams
E
Amazon SNS and AWS Step Functions

Show answer and explanation

Correct answers: A, C

Explanation

To implement an event-driven architecture that supports fan-out and asynchronous processing, you can use Amazon SNS with Amazon SQS or Amazon EventBridge with Amazon SQS. Both combinations allow events to be routed to multiple processing workflows (order validation and payment processing) independently and asynchronously. SNS and EventBridge handle the fan-out, while SQS ensures decoupling and reliable delivery of messages to each workflow.

A. Correct.
Amazon SNS and Amazon SQS is correct because SNS can fan out messages to multiple SQS queues, enabling parallel processing of the order validation and payment workflows. SQS ensures that events are processed asynchronously.
B. Incorrect.
Amazon Kinesis Data Streams and AWS Lambda is incorrect because Kinesis is more suited for high-throughput event streaming rather than fan-out scenarios. While Lambda can process events from Kinesis, it does not natively support the fan-out model required here.
C. Correct.
Amazon EventBridge and Amazon SQS is correct because EventBridge can route events to multiple SQS queues, ensuring asynchronous and independent processing of workflows.
D. Incorrect.
AWS Step Functions and Amazon Kinesis Data Streams is incorrect because Step Functions are designed for orchestrating workflows, not for implementing fan-out or asynchronous processing. Kinesis, in this context, is not relevant for the fan-out requirement.
E. Incorrect.
Amazon SNS and AWS Step Functions is incorrect because although SNS can fan out messages, Step Functions is not well-suited for independent and asynchronous processing of events. It is primarily designed for orchestrating workflows in a more synchronous manner.

DOP-C02 Question 304

Single answer

Your team is building a real-time analytics platform for processing customer orders. The architecture requires the events from an order processing system to be processed by multiple downstream services simultaneously, such as a billing service, a notification service, and a machine learning service for fraud detection. Each service must process the events independently and at its own pace. Which AWS service or combination of services would best enable this fan-out pattern?

A
Amazon SNS with multiple Amazon SQS queues subscribed to the topic
B
Amazon Kinesis Data Streams with multiple consumers
C
Amazon S3 Event Notifications with Lambda functions for each downstream service
D
Amazon MQ for message fan-out to multiple consumers

Show answer and explanation

Correct answer: A

Explanation

The best solution for implementing a fan-out pattern in AWS is to use Amazon SNS in combination with multiple Amazon SQS queues. SNS allows for the publication of messages to a topic, and each subscribed SQS queue can independently receive and process the message. This approach provides scalability, decoupling, and fault tolerance, making it ideal for event-driven architectures where multiple downstream services need to process the same event at their own pace.

A. Correct.
Correct. Amazon SNS with multiple Amazon SQS queues allows you to implement a fan-out pattern where a single event is published to an SNS topic, and each subscribed SQS queue can independently receive and process the event. This meets the requirement for independent processing by downstream services.
B. Incorrect.
Incorrect. While Amazon Kinesis Data Streams can support multiple consumers, it is more suited for real-time streaming data where consumers are consuming from a shared stream. It does not inherently support the fan-out pattern as effectively as SNS and SQS for this scenario.
C. Incorrect.
Incorrect. Amazon S3 Event Notifications are specific to S3 bucket events and are not designed for generic event-driven architectures. This option does not fit the described use case.
D. Incorrect.
Incorrect. While Amazon MQ supports message brokering and multiple consumers, it is typically used for traditional message queuing scenarios and lacks the scalability and simplicity of the SNS-SQS combination for event fan-out.

DOP-C02 Question 305

Single answer

You are designing a serverless event-driven architecture for a video processing application on AWS. When a new video is uploaded to an S3 bucket, metadata about the video should be processed and stored in DynamoDB, and the video itself should be transcoded into multiple formats. Both tasks (metadata processing and transcoding) need to happen concurrently and independently. Which solution would best achieve this architecture?

A
Configure an S3 event notification to directly invoke two AWS Lambda functions: one for metadata processing and the other for transcoding.
B
Use an S3 event notification to publish an event to an Amazon SNS topic, and subscribe two AWS Lambda functions to the topic.
C
Use an S3 event notification to send messages to an Amazon SQS queue, and have two AWS Lambda functions poll the queue.
D
Use an S3 event notification to trigger a Step Functions workflow to orchestrate the metadata processing and transcoding tasks.

Show answer and explanation

Correct answer: B

Explanation

The application requires a fan-out architecture to process two tasks (metadata processing and transcoding) concurrently and independently when a new video is uploaded to S3. Amazon SNS is the best service for implementing a fan-out pattern, as it allows multiple subscribers (Lambda functions) to independently process the same event in parallel. Other options either lack the ability to fan out events or introduce unnecessary complexity.

A. Incorrect.
This option is not ideal because S3 does not allow simultaneous invocation of multiple Lambda functions for a single event. You would need a fan-out mechanism like SNS to achieve concurrent and independent processing.
B. Correct.
This is the correct solution. SNS enables a fan-out pattern where multiple subscribers (in this case, Lambda functions) can independently process the same event concurrently. This matches the requirement for both metadata processing and transcoding to happen independently.
C. Incorrect.
Using SQS would require additional complexity. SQS is designed for message queuing and would not natively support the fan-out pattern required for this use case. Each Lambda function would need independent polling logic.
D. Incorrect.
Step Functions is more suitable for orchestrating sequential or interdependent tasks. In this scenario, the tasks are independent and need to run concurrently, which is better handled by SNS.
