- A
Use a scheduled scaling action to increase capacity during peak hours.
Why wrong: Scheduled scaling is not dynamic; requires prior knowledge of traffic patterns.
- B
Manually add EC2 instances during peak hours.
Why wrong: Manual intervention is not automatic.
- C
Set the environment to use a fixed number of EC2 instances.
Why wrong: Fixed number does not scale automatically.
- D
Configure Auto Scaling triggers based on CloudWatch alarms.
Auto Scaling triggers allow the environment to scale out based on metrics like CPU.

DVA-C02 Deployment Practice Question
This DVA-C02 practice question tests your understanding of deployment. 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 developer is deploying a web application using AWS Elastic Beanstalk. The application experiences high traffic during peak hours. The developer wants to ensure that the environment can scale out quickly without manual intervention. Which Elastic Beanstalk configuration should be used?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Configure Auto Scaling triggers based on CloudWatch alarms.
Option D is correct because Elastic Beanstalk integrates with Auto Scaling to automatically adjust the number of EC2 instances based on demand. By configuring Auto Scaling triggers that respond to CloudWatch alarms (e.g., CPU utilization > 70%), the environment can scale out quickly and without manual intervention during peak hours.
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 scheduled scaling action to increase capacity during peak hours.
Why it's wrong here
Scheduled scaling is not dynamic; requires prior knowledge of traffic patterns.
- ✗
Manually add EC2 instances during peak hours.
Why it's wrong here
Manual intervention is not automatic.
- ✗
Set the environment to use a fixed number of EC2 instances.
Why it's wrong here
Fixed number does not scale automatically.
- ✓
Configure Auto Scaling triggers based on CloudWatch alarms.
Why this is correct
Auto Scaling triggers allow the environment to scale out based on metrics like CPU.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse scheduled scaling (Option A) with dynamic scaling, not realizing that scheduled actions cannot handle unpredictable spikes, while CloudWatch-triggered Auto Scaling provides real-time, event-driven scaling.
Detailed technical explanation
How to think about this question
Under the hood, Elastic Beanstalk creates an Auto Scaling group with a launch configuration. The Auto Scaling group uses CloudWatch metric alarms (e.g., Average CPUUtilization > 75% for 5 minutes) to trigger scale-out policies, which increment the desired capacity by a specified number of instances. This dynamic scaling ensures the application can handle sudden traffic surges without pre-defined schedules.
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
- 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.
