AWS - Auto Scaling

Given this step scaling policy snippet:

{"StepAdjustments": [{"MetricIntervalLowerBound": 0, "ScalingAdjustment": 2}]}

What happens when the metric breaches the alarm threshold?

ACapacity remains unchanged

BCapacity increases by 2 units

CCapacity decreases by 2 units

DCapacity increases by 1 unit

Step-by-Step Solution

Solution:

Step 1: Understand StepAdjustments
MetricIntervalLowerBound of 0 means the adjustment applies when metric is above threshold.
Step 2: Apply ScalingAdjustment
ScalingAdjustment of 2 means increase capacity by 2 units.
Final Answer:
Capacity increases by 2 units -> Option B
Quick Check:
Step scaling with positive adjustment = capacity increase [OK]

Quick Trick: Positive ScalingAdjustment increases capacity [OK]
