An application uses a DynamoDB table to store data with each record being 6KB in size. The application needs to perform 100 eventually consistent read operations per second and 40 write operations per second. What is the provisioned RCU value required to meet these requirements?

Answer options:

A.200 RCU
B.600 RCU
C.300 RCU
D.100 RCU

Answer: D
Option D is CORRECT.
1RCU is equivalent to two strongly consistent reads per second of an item up to 4KB in size. Thus, to calculate the required RCU in this scenario, we need to:
1. Round up the item size to the nearest 4KB (8KB)
2. Divide by 4KB to calculate the number of read units (8/4 = 2)
3. Divide by 2 to calculate the number of eventually consistent read units per item (2/2 = 1)
4. Multiple by operations per second to get the total RCU required (1*100 = 100 RCU)
