DynamoDB - Backup and Recovery

Why does DynamoDB use encryption at rest instead of only relying on network security?

ABecause encryption at rest reduces storage costs

BBecause data stored on disks can be accessed if not encrypted, even if network is secure

CBecause encryption at rest speeds up data access

DBecause network security is not important

Step-by-Step Solution

Solution:

Step 1: Understand difference between network security and encryption at rest
Network security protects data during transfer; encryption at rest protects stored data.
Step 2: Explain why encryption at rest is necessary
Data on disks can be accessed if not encrypted, so encryption at rest protects against physical or unauthorized disk access.
Final Answer:
Because data stored on disks can be accessed if not encrypted, even if network is secure -> Option B
Quick Check:
Encryption at rest protects stored data beyond network security [OK]

Quick Trick: Encryption at rest protects data on disks, not just in transit [OK]
