DynamoDB - Cost Optimization and MonitoringWhich of the following is the correct way to specify Reserved Capacity units in DynamoDB?ABy defining the number of backup snapshots per monthBBy setting the maximum storage size in GBCBy specifying the number of read and write capacity units per secondDBy choosing the number of indexes on the tableCheck Answer
Step-by-Step SolutionSolution:Step 1: Understand what Reserved Capacity units representReserved Capacity is about throughput, measured in read and write capacity units per second.Step 2: Eliminate unrelated optionsStorage size, backups, and indexes are not part of Reserved Capacity specification.Final Answer:By specifying the number of read and write capacity units per second -> Option CQuick Check:Reserved Capacity units = throughput units per second = C [OK]Quick Trick: Reserved Capacity is about throughput units, not storage or backups [OK]Common Mistakes:MISTAKESConfusing capacity units with storage sizeThinking backups count as capacity unitsMixing indexes with capacity units
