A batch processing job can be interrupted and restarted from checkpoints. The business wants to lower compute cost while still keeping the workload resilient to interruptions. Which two choices are best? Select two.
Answer choices
Why each option matters
Good practice is not just finding the correct option. The wrong answers often show the exact trap the exam wants you to fall into.
A
Best answer
Run the workload on Amazon EC2 Spot Instances.
Spot Instances are significantly cheaper than On-Demand capacity and are a good fit when the workload can tolerate interruption. Because the job can restart from checkpoints, interruptions are acceptable.
B
Best answer
Store checkpoints in durable storage such as Amazon S3.
Durable checkpoints allow the job to resume from the last saved state after an interruption. This avoids reprocessing all work from the beginning and makes interruption recovery practical.
C
Distractor review
Use a single On-Demand instance in one Availability Zone only.
A single On-Demand instance does not provide strong interruption resilience and gives up the main cost advantage of Spot. It is also less tolerant of an AZ failure.
D
Distractor review
Disable automatic replacement so the job is never restarted.
Disabling replacement defeats resilience. If the instance is interrupted or fails, the batch job would remain down until someone manually intervenes.
E
Distractor review
Keep all intermediate state only in instance memory.
Instance memory is lost when the instance stops or is interrupted. Restartable batch jobs need durable checkpoint storage rather than ephemeral in-memory state only.
Common exam trap
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.
Technical deep dive
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.

FAQ
Questions learners often ask
What does this SAA-C03 question test?
Read the scenario before looking for a memorised answer.
What is the correct answer to this question?
The correct answer is: Run the workload on Amazon EC2 Spot Instances. — For restartable batch processing, Spot Instances are a strong cost-saving option because the workload can tolerate interruption. Storing checkpoints in durable storage such as Amazon S3 allows the job to resume from the last saved state instead of starting over. Together, these choices lower compute cost while preserving recovery from interruption. A single On-Demand instance is less resilient and does not deliver meaningful cost savings for this use case. Disabling replacement makes recovery manual and slow. Memory is temporary, so it cannot be the only place to keep progress for a restartable workload.
