AWS Certified Solutions Architect Associate SAA-C03 Practice Question

Designing for resilience includes planning for unexpected spikes in traffic and ensuring that AWS services can scale to meet demand. Increasing the provisioned read/write capacity units for the DynamoDB table is the correct action to address the issue. By provisioning more throughput, the ability to handle higher levels of traffic without throttling is ensured. Requesting a service quota increase would be relevant if the application was hitting account-level service limits, but this is less likely to be the immediate solution to throttling, which is often encountered at the table level. Similarly, monitoring with Amazon CloudWatch is useful for awareness and alarms, but it does not address the need to accommodate increased traffic. Implementing exponential backoff is a retry strategy to handle request throttling but does not by itself prevent throttling from occurring initially.
