The answer is AWS Instance Scheduler, the correct choice for automating SAP EC2 start/stop actions because it is a purpose-built AWS solution that natively handles scheduling without requiring custom code. This service allows you to define recurring start and stop times for EC2 instances, directly reducing costs for non-production SAP environments by ensuring instances run only when needed. On the AWS Certified SAP on AWS Specialty PAS-C01 exam, this question tests your ability to identify the simplest managed solution for operational cost optimization, often appearing as a trap where Lambda or CloudWatch Events seem viable but require additional development and maintenance. A common mistake is choosing Lambda, but remember that Instance Scheduler is the pre-built, deployment-ready answer for scheduling—think of it as the "set-it-and-forget-it" tool for SAP instance lifecycle management. Memory tip: "Scheduler schedules, Lambda labors" to recall that Instance Scheduler is the direct, no-code path for start/stop automation.
PAS-C01 Technology Practice Question
This PAS-C01 practice question tests your understanding of technology. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. 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 to automate the start and stop of SAP applications in non-production environments to reduce costs. The SAP systems run on multiple EC2 instances. Which AWS service can be used to schedule start and stop actions?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
AWS Instance Scheduler
Option B is correct because AWS Instance Scheduler is a solution specifically designed to start and stop EC2 instances on a schedule. Option A is wrong because Lambda can be used but requires custom code; Instance Scheduler is simpler. Option C is wrong because CloudWatch Events can trigger Lambda, but not directly stop instances. Option D is wrong because OpsWorks is for configuration management, not scheduling.
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 OpsWorks
Why it's wrong here
OpsWorks is for configuration management, not scheduling.
✗
AWS Lambda with custom code
Why it's wrong here
Lambda can be used but requires custom development; Instance Scheduler is a turnkey solution.
✓
AWS Instance Scheduler
Why this is correct
Instance Scheduler is a ready-made solution that uses Lambda and DynamoDB to start/stop instances.

✗
Amazon CloudWatch Events
Why it's wrong here
CloudWatch Events can trigger Lambda, but the Instance Scheduler is the recommended approach.
Common exam traps
Common exam trap: answer the scenario, not the keyword
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
How to think about this question
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.
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.
Use explanations to understand the rule behind the answer.
TExam Day Tips
→Underline the problem statement mentally.
→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 startup's cloud architect reviews their monthly bill and notices costs are higher than expected for a long-running batch job. Switching from on-demand instances to Reserved Instances — or using Spot/Preemptible VMs — can reduce compute costs by up to 72 %. Questions like this test whether you understand the tradeoffs between commitment, flexibility, and cost across cloud pricing models.
