AWS Backup offers centralized management, scheduling, and retention of backups for supported AWS services including Amazon DynamoDB. It enables compliance retention with minimal management.

From AWS Documentation:

“AWS Backup provides centralized backup management across AWS services, including DynamoDB. You can define backup plans, schedules, and retention policies to meet business or regulatory requirements.”

(Source: AWS Backup Developer Guide – Backing up DynamoDB Tables)

Why B is correct:

Automatically manages backup scheduling and retention (7 years).

Centralized compliance monitoring via AWS Backup Audit Manager.

Fully managed and requires no custom automation.

Why others are incorrect:

A: PITR is for continuous restore within 35 days, not long-term compliance retention.

C & D: Manual or Lambda-based backups require custom management and increase operational complexity.

For a MySQL database experiencing high write operations, using Amazon RDS with Provisioned IOPS (io1 or io2) SSD storage is recommended to achieve consistent and low-latency performance. Provisioned IOPS allows you to specify a desired IOPS rate, which is crucial for write-intensive workloads.

Monitoring write operation metrics through Amazon CloudWatch enables you to observe performance and adjust the provisioned IOPS as needed to meet application demands.

Amazon Kinesis Data Streams provides a highly scalable and durable service for ingesting real-time streaming data. By decoupling ingestion and processing, Kinesis can handle large spikes in traffic without service disruption. Lambda functions (or other consumers) can then process the data as it arrives, scaling automatically. This pattern avoids 503 errors due to compute saturation and delivers a resilient, serverless, and highly scalable architecture.

Reference Extract from AWS Documentation / Study Guide:

" Kinesis Data Streams provides a scalable and durable real-time data streaming service. Coupling Kinesis with AWS Lambda enables event-driven processing, elasticity, and decoupling between ingestion and processing layers. "
