Question

Company B is writing 10 items to the Dynamo DB table every second. Each item is 15.5Kb in size.  What would be the required provisioned write throughput for best performance? Choose the correct answer from the options below.

A. 10

B. 160

C. 155

D. 16

Answer 1

Correct option is :- Answer - B.

As per the documentation, when working with write capacity, the rule is to divide the item size by 1KB.Hence, 15.5 divided by 1 is 15.5

When we round-off to the nearest 1KB value, it's 16.Since we are writing 10 items per second, we need to multiply 10*16 = 160.
