Question

 You are developing an application that is working with a DynamoDB table. You need to create a query that has search criteria.

Which of the following must be done to work with search queries? Choose 2 answers from the options given below.

A. Specify a key condition expression in the query.

B. Specify a partition key name and value in the equality condition.

C. Specify a sort key name and value in the equality condition.

D. Specify a filter expression.

Answer 1

Answer - A and B.

The AWS Documentation mentions the following.

Key Condition Expression.

To specify the search criteria, you use a key condition expression-a string that determines the items to be read from the table or index.

You must specify the partition key name and value as an equality condition.

Option C is incorrect since you need to mention the partition key and not the sort key.

Option D is incorrect since this is used to filter results further.
