Quick Answer
The answer is Amazon S3, AWS Lambda, and Amazon EventBridge. This combination forms a fully serverless batch processing solution because EventBridge acts as the scheduler to trigger jobs on a defined cron schedule, Lambda provides the compute to process incoming files without managing servers, and S3 serves as the durable, scalable storage layer for the files that were previously on an FTP server. On the AWS Certified Solutions Architect Professional SAP-C02 exam, this scenario tests your ability to distinguish serverless orchestration from legacy or stateful services—a common trap is choosing Amazon EC2 (which requires server management) or Amazon SWF (designed for long-running workflows, not simple scheduled batch processing). The key insight is that for stateless, event-driven batch jobs, you need a scheduler, a compute engine, and a storage service, all of which are serverless. Memory tip: think "Schedule, Process, Store" to recall EventBridge, Lambda, and S3 in that order.
This SAP-C02 practice question tests your understanding of accelerate workload migration and modernization. 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 migrating a legacy batch processing system to AWS. The batch jobs run on a schedule and process files from an FTP server. The company wants a serverless solution. Which THREE AWS services should be combined to implement the solution?
Amazon EventBridge (CloudWatch Events)
EventBridge can trigger Lambda on a schedule.
Amazon EC2 with Auto Scaling
Why wrong: EC2 is not serverless.
AWS Lambda
Lambda processes the files serverlessly.
Amazon S3
S3 stores the processed files.
Amazon Simple Workflow Service (SWF)
Why wrong: SWF is for workflows, not needed for simple scheduled batch.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Amazon EventBridge (CloudWatch Events)
Options A, B, and D are correct. Option A (EventBridge) schedules events. Option B (Lambda) processes files. Option D (S3) stores files. Option C is wrong because EC2 is not serverless. Option E is wrong because SWF is a workflow service for long-running tasks.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Detailed technical explanation
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
A media company stores terabytes of video archives that are accessed once a year for audit purposes. Moving these objects to a cold storage tier (Azure Archive, S3 Glacier, or Google Nearline) costs a fraction of hot storage. Questions like this test whether you understand storage tiers, access frequency tradeoffs, and retrieval latency requirements.

Same concept, more angles
These questions test the same concept from different angles. Work through them to make sure you can recognise it however the exam phrases it.
Variation 1. A company is migrating a batch processing workload to AWS. The workload runs daily and processes large files. Which TWO AWS services are most suitable for this workload? (Choose TWO.)
easyWhy A: AWS Batch manages batch computing jobs. AWS Step Functions orchestrates workflows. Option A is wrong because Lambda has time limits. Option C is wrong because ECS is for containers, not specifically batch. Option D is wrong because SQS is for message queuing.
Variation 2. A company is migrating a batch processing workload to AWS. The workload runs daily on a single on-premises server and takes 6 hours to complete. The company wants to reduce processing time and cost. Which approach should the solutions architect recommend?
easyWhy A: AWS Batch can orchestrate parallel processing across multiple EC2 or Fargate resources, reducing time. A single larger instance may not reduce time as much as parallel processing. Lambda has a 15-minute execution limit. Step Functions alone does not provide compute.
