- A
AWS Lambda
Why wrong: Lambda functions have a maximum 15-minute timeout — they can't directly manage workflows running for up to a year.
- B
Amazon SQS
Why wrong: SQS queues messages but doesn't orchestrate multi-step workflows with state management, human approvals, or the ability to pause for up to a year.
- C
AWS Step Functions (Standard Workflows)
Step Functions Standard Workflows support executions lasting up to one year, human approval steps via task tokens, parallel execution, and comprehensive error handling — ideal for long-running business processes.
- D
Amazon EventBridge
Why wrong: EventBridge routes events based on rules but doesn't maintain workflow state or support human approval steps as a workflow orchestration service.

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 needs a managed workflow service to coordinate long-running business processes that may require human approval steps and can run for up to one year. Which AWS service handles this?

Correct answer & explanation
✓
AWS Step Functions (Standard Workflows)
AWS Step Functions Standard Workflows are designed for long-running, durable, and auditable workflows that can run for up to one year, making them ideal for coordinating business processes that require human approval steps. They provide built-in error handling, retries, and state management, which are essential for orchestrating multi-step processes with human intervention.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
AWS Lambda
Why it's wrong here
Lambda functions have a maximum 15-minute timeout — they can't directly manage workflows running for up to a year.

- ✗
Amazon EventBridge
Why it's wrong here
EventBridge routes events based on rules but doesn't maintain workflow state or support human approval steps as a workflow orchestration service.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse AWS Step Functions with Amazon EventBridge, but EventBridge is only for event routing and cannot orchestrate long-running workflows with human approval steps, while Step Functions Standard Workflows are explicitly built for this purpose.
Detailed technical explanation
How to think about this question
Step Functions Standard Workflows use a JSON-based Amazon States Language (ASL) to define state machines, with each state transition being recorded in Amazon CloudWatch Logs for auditability. The service supports up to 12 months of execution history, and each workflow execution can include 'Task' states that integrate with over 200 AWS services, including Lambda, SQS, and DynamoDB, as well as 'Wait' states for human approval timeouts. A real-world scenario is an order fulfillment process where a Step Function pauses for a manager to approve a discount via an SNS notification, then resumes to process payment and shipping.
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.
