- A
Use Amazon EventBridge cross-account event buses in each target account
EventBridge natively supports cross-account event routing.
- B
Publish events to an AWS Lambda function in each target account
Why wrong: Not scalable and adds complexity.
- C
Use Amazon Kinesis Data Streams with cross-account access
Why wrong: Kinesis is for streaming data, not event routing.
- D
Create an Amazon SNS topic in the central account and subscribe SQS queues in each target account
Why wrong: SNS cross-account is possible but less scalable than EventBridge.

SAP-C02 Design for New Solutions Practice Question
This SAP-C02 practice question tests your understanding of design for new solutions. 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 is designing an event-driven architecture using Amazon EventBridge. They have multiple AWS accounts that need to receive events from a central account. What is the MOST scalable and secure way to route events to these accounts?
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
✓
Use Amazon EventBridge cross-account event buses in each target account
Amazon EventBridge cross-account event buses allow a central account to route events directly to event buses in target accounts using resource-based policies. This approach is serverless, fully managed, and scales horizontally without any intermediate components, making it the most scalable and secure solution. It avoids the complexity and potential bottlenecks of Lambda invocations, Kinesis stream management, or SNS-to-SQS fan-out across accounts.
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 often default to SNS or SQS for cross-account messaging, but EventBridge's native cross-account event bus feature is specifically designed for this use case and is more scalable and secure because it uses resource-based policies and avoids intermediate services.
Detailed technical explanation
How to think about this question
EventBridge cross-account event buses use resource-based policies that allow the central account to put events directly into a target account's event bus, which then routes events to rules and targets within that account. This eliminates the need for intermediate services and reduces latency because events are pushed in near real-time. In a real-world scenario, a central observability account can send compliance or security events to multiple accounts without managing custom forwarding logic, and EventBridge supports event filtering at the rule level to reduce unnecessary data transfer.
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 company's IT admin needs to give a contractor read-only access to production logs without sharing account credentials. Using role-based access control (RBAC) and temporary scoped permissions — not a permanent shared password — is the correct pattern. Questions like this test whether you can apply least-privilege access across cloud identity services.
