The answer is to use a step scaling policy with a lower scale-out threshold and a larger adjustment. This is correct because step scaling policies allow you to define distinct scaling adjustments based on the magnitude of the alarm breach, meaning that during a traffic spike, a larger deviation from the threshold triggers a more aggressive addition of tasks, rapidly absorbing the load before tasks become unhealthy. On the AWS Certified Solutions Architect Professional SAP-C02 exam, this question tests your understanding of how to balance proactive scaling with cost efficiency, often contrasting step scaling against target tracking, which is more reactive and can lag behind sudden spikes. A common trap is to assume that increasing health check intervals or memory will solve the issue, but those don’t address scaling speed. Memory tip: think “step up fast” — step scaling takes bigger steps when the spike is bigger, preventing task flapping.
SAP-C02 Continuous Improvement for Existing Solutions Practice Question
This SAP-C02 practice question tests your understanding of continuous improvement for existing solutions. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. 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 runs a critical application on Amazon ECS Fargate. The application uses an Application Load Balancer as the front end. Recently, the application experienced a spike in traffic, and many tasks were marked as unhealthy and replaced. The team wants to improve resilience to traffic spikes without over-provisioning. What should the team do?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Use a step scaling policy with a lower scale-out threshold and a larger adjustment
Option B is correct because step scaling policies respond more aggressively to larger deviations, helping to add capacity faster. Option A (increase memory) does not directly affect scaling. Option C (increase health check interval) would slow detection of unhealthy tasks. Option D (use target tracking) is reactive and may not handle spikes well.
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.
✓
Use a step scaling policy with a lower scale-out threshold and a larger adjustment
Why this is correct
Step scaling can add more tasks faster when CPU exceeds thresholds.
Related concept
Read the scenario before looking for a memorised answer.
✗
Increase the task memory allocation to improve performance
Why it's wrong here
Performance improvement does not address scaling speed.
✗
Increase the health check interval to reduce the number of tasks marked unhealthy
Why it's wrong here
Longer interval means slower detection of actual issues.
✗
Use a target tracking scaling policy with a higher target value
Why it's wrong here
Higher target delays scaling.
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
An e-commerce site experiences heavy traffic on Black Friday and near-zero traffic during off-peak weeks. Rather than provisioning permanent large VMs, the team uses auto-scaling groups that add capacity automatically under load and reduce it overnight. Questions like this test whether you understand elasticity, availability zones, and cloud compute scaling patterns.
