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.

Answer options:

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 – 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.
