Explanation:
10
One Read Capacity Unit represents one strongly consistent read per second, or two eventually consistent reads per second, for an item up to 4 KB in size. If you need to read an item that is larger than 4 KB, DynamoDB will need to consume additional read capacity units. The total number of Read Capacity Units required depends on the item size, and whether you want an eventually consistent or strongly consistent read.
So, in the above case, 4KB / 4 KB = 1 read capacity unit.
So, in the above case, 1 x 10 = 10 read capacity units.

As a software engineer at an IT company, you are contributing to the development of an internal application that features dashboards designed for data visualization. In the process of provisioning an AWS DynamoDB table, you need to ensure that it supports 10 strongly consistent reads per second, with each read being 4 KB in size.
Calculate the number of Read Capacity Units (RCUs) required to achieve this.
