SAP-C02 Continuous Improvement for Existing Solutions Practice Question
A company uses AWS Elastic Beanstalk to deploy a web application. The application experiences increased traffic, and the environment's Auto Scaling group is not scaling out quickly enough. What should a solutions architect do to improve the scaling response?
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
✓
Reduce the cooldown period for the Auto Scaling group.
Reducing the cooldown period allows the Auto Scaling group to react faster to increased traffic, enabling quicker scale-out. Option A is incorrect because decreasing the CPU utilization threshold for scale-out alarms would cause the group to scale out at lower CPU levels, potentially scaling out sooner but not necessarily improving the speed of response. Option B is incorrect because increasing the minimum number of instances does not speed up scaling; it only ensures a higher baseline capacity. Option D is incorrect because using larger instance types handles more traffic per instance but does not improve the scaling response time.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Decrease the CPU utilization threshold for scale-out alarms.
Why it's wrong here
This triggers scaling earlier but does not speed up the scaling action itself.
- ✗
Increase the minimum number of instances in the Auto Scaling group.
Why it's wrong here
This keeps more instances running but does not speed up scaling out.
- ✓
Reduce the cooldown period for the Auto Scaling group.
Why this is correct
A shorter cooldown allows new instances to be launched sooner after a scaling activity.
- ✗
Use a larger instance type to handle more traffic.
Why it's wrong here
Larger instances may handle more traffic but do not improve scaling speed.
