The answer is scheduled scaling, enhanced health reporting, and CloudWatch alarms based on response time. This combination directly addresses the cost optimization and performance requirements by using a time-based policy to match capacity to predictable traffic patterns, while the response-time alarm handles unexpected spikes without over-provisioning. Enhanced health reporting gives you the granular metrics needed to fine-tune those scaling thresholds. On the AWS Certified SysOps Administrator Associate SOA-C02 exam, this scenario tests your ability to distinguish between proactive scheduled scaling and reactive dynamic scaling, with a common trap being the selection of multiple environments or launch templates—neither of which directly optimizes cost for a single fluctuating workload. Remember the memory tip: “Schedule the predictable, alarm the unpredictable, and monitor the middle.”
SOA-C02 Deployment, Provisioning, and Automation Practice Question
This SOA-C02 practice question tests your understanding of deployment, provisioning, and automation. 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 using AWS Elastic Beanstalk to deploy a web application. The application experiences high traffic during business hours and low traffic at night. The administrator wants to minimize costs while ensuring performance. Which THREE actions should the administrator take? (Choose THREE.)
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "minimum / minimize"
Why it matters: Asks for the least resource use — fewest addresses, smallest subnet, lowest overhead. Eliminate over-provisioned options even if they would technically work.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Enable enhanced health reporting and monitoring for the environment.
Options A, C, and E are correct. Configuring the Auto Scaling group with a scheduled scaling policy to increase capacity during business hours and decrease at night optimizes cost. Enabling enhanced health reporting provides better insights. Setting up CloudWatch alarms to trigger scaling based on response time ensures performance during unexpected spikes. Option B (launch template) is not needed for scaling. Option D (multiple environments) may increase costs.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

✗
Use a launch template to define instance configuration.
Why it's wrong here
Launch templates are for instance configuration, not scaling actions.
✓
Set up CloudWatch alarms to trigger scaling based on response time.
Why this is correct
Alarms based on response time can scale out during unexpected load.

✗
Deploy the application in multiple Elastic Beanstalk environments.
Why it's wrong here
Multiple environments increase cost and complexity unnecessarily.
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.

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.
