An application uses a DynamoDB table to store data with each record being 6KB in size. The application needs to perform 100 strongly 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.150 RCU
C.600 RCU
D.100 RCU

Answer: A
Option A is CORRECT.
1RCU is equivalent to one strongly consistent read per second for an item up to 4 KB 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 strongly consistent read units (8/4 = 2)
3. Multiple by operations per second to get the total RCU required (2*100 = 200 RCU)
