Answer 1

Amazon DynamoDB offers two types of primary keys: Single-key (Partition key) and Composite key (Partition key and Sort key) for organizing data in the database.

Step-by-step explanation:

The two options for primary keys in Amazon DynamoDB are: A. Single-key and Composite key. A Single-key, also known as a Partition key, is a simple primary key composed of one attribute. A Composite key includes two attributes: the Partition key and the Sort key. The Partition key determines the partition in which the data is stored, and the Sort key allows further sorting of the data within that partition.
