AWS Certified CloudOps Engineer Associate SOA-C03 Practice Question

Switching the table from provisioned capacity to on-demand capacity removes the need to specify or scale write capacity units. DynamoDB instantly accommodates sudden, short-lived spikes up to double the previous peak traffic and then continues to expand as required, so the flash-sale surge is served without throttling. Because the startup pays only for actual read and write requests, normal-time charges stay close to their current level and no manual scheduling is needed. Raising maximum provisioned capacity or reducing the target utilization still suffers from scaling ramp-up delays and incurs higher standby costs. Adaptive capacity only reallocates existing throughput across partitions; it cannot create additional capacity, so throttling would persist.
