A developer has built an application that inserts data into an Amazon DynamoDB table.

Requirement Summary:

DynamoDBProvisioned Mode

ProvisionedThroughputExceededException error occurring

App hosted on a smallburstable EC2 instance

Option A: Move to a larger EC2 instance

❌May improve local performance, butdoes not solve DynamoDB provisioned throughputlimits.

Option B: Increase DynamoDB RCUs

✅Valid: This directly increases theread throughputcapacity of the table.

Helps handle more traffic andreduce throughput exceptions.

Option C: Reduce frequency via exponential backoff

✅Best practice: Usingexponential backoffandjitterreduces request pressure andspreads retriesout to avoid spiking.

Option D: Increase frequency of retries by reducing delay

❌Opposite of best practice. Increases load, worsening the issue.

Option E: Change to on-demand mode

✅Also validin general, but question is scoped around provisioned capacity.

Sinceminimizing cost or workload typeisn't mentioned, andscaling the existing modelis the focus, prefer B and C.
