Question 32 of 100 | ← Chapter 2

An application uses Amazon DynamoDB as its data store and must support strongly consistent reads of 100 items per second. Each item is 5 KB in size. What should the table's provisioned read capacity be set to?

• A. 50 read capacity units
• B. 100 read capacity units
• C. 200 read capacity units ✓
• D. 500 read capacity units

Correct Answer: C. 200 read capacity units

Explanation

1 Read Capacity Unit (RCU) supports one strongly consistent read of up to 4 KB. A 5 KB item requires 2 RCUs. For 100 items per second: 100 × 2 = 200 RCUs.
