A cloud engineer is configuring an auto-scaling group and wants to add instances based on a sustained increase in CPU utilization above 80% for 5 minutes. Which scaling policy type 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
✓
Step scaling policy
Step scaling policies allow you to define steps that respond to metric breaches with specific actions, such as adding a certain number of instances when CPU exceeds 80% for a specified period.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Target tracking scaling policy
Why it's wrong here
Target tracking maintains a target metric value (e.g., 70% CPU) and adjusts capacity accordingly, but does not allow custom step adjustments.
- ✓
Step scaling policy
Why this is correct
Step scaling policies allow you to define specific adjustments based on the magnitude of the metric breach.
- ✗
Simple scaling policy
Why it's wrong here
Simple scaling waits for cooldown periods but does not allow multiple steps based on metric magnitude.
- ✗
Scheduled scaling policy
Why it's wrong here
Scheduled scaling is time-based, not metric-based.
