DynamoDB - Cost Optimization and Monitoring

AAuto-scaling increases capacity gradually; some throttling may occur during scaling

BNo throttling occurs because capacity instantly matches traffic

CCosts remain fixed regardless of traffic spikes

DAuto-scaling disables billing during spikes

Step-by-Step Solution

Solution:

Step 1: Understand provisioned mode with auto-scaling
Auto-scaling adjusts capacity based on usage but takes time to react; capacity changes are gradual.
Step 2: Predict behavior during sudden spikes
During sudden spikes, capacity may lag behind demand causing some throttling until scaling catches up; costs increase with capacity.
Final Answer:
Auto-scaling increases capacity gradually; some throttling may occur during scaling -> Option A
Quick Check:
Auto-scaling = gradual capacity change, possible throttling [OK]

Quick Trick: Auto-scaling reacts slowly; expect throttling during spikes [OK]

Common Mistakes:

MISTAKES

Assuming instant capacity increase
Thinking costs stay fixed during spikes
Believing billing pauses during scaling
