Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Step scaling
Why it's wrong here
Step scaling is based on alarm thresholds, not a target value.
- ✗
Simple scaling
Why it's wrong here
Simple scaling requires manual steps; not ideal for dynamic adjustment.
- ✗
Scheduled scaling
Why it's wrong here
Scheduled scaling is time-based, not reactive to queue depth.
- ✓
Target tracking scaling
Why this is correct
Target tracking keeps the metric near a target value (e.g., 100 messages).
