Question #: 145
Topic #: 1

[All AWS Certified Developer - Associate DVA-C02 Questions]

A developer is creating an AWS Lambda function that searches for items from an Amazon DynamoDB table that contains customer contact information. The DynamoDB table items have the customer’s email_address as the partition key and additional properties such as customer_type, name and job_title.

The Lambda function runs whenever a user types a new character into the customer_type text input. The developer wants the search to return partial matches of all the email_address property of a particular customer_type. The developer does not want to recreate the DynamoDB table.

What should the developer do to meet these requirements?

A. Add a global secondary index (GSI) to the DynamoDB table with customer_type as the partition key and email_address as the sort key. Perform a query operation on the GSI by using the begins_with key condition expression with the email_address property.
B. Add a global secondary index (GSI) to the DynamoDB table with email_address as the partition key and customer_type as the sort key. Perform a query operation on the GSI by using the begins_with key condition expression with the email_address property.
C. Add a local secondary index (LSI) to the DynamoDB table with customer_type as the partition key and email_address as the sort key. Perform a query operation on the LSI by using the begins_with key condition expression with the email_address property.
D. Add a local secondary index (LSI) to the DynamoDB table with job_title as the partition key and email_address as the sort key. Perform a query operation on the LSI by using the begins_with key condition expression with the email_address property.

Option B (Global Secondary Index with email_address as Partition Key): Add a global secondary index (GSI) to the DynamoDB table. Set email_address as the partition key and customer_type as the sort key for the GSI. Perform a query operation on the GSI using the begins_with key condition expression with the email_address property.

A. Add a global secondary index (GSI) to the DynamoDB table with customer_type as the partition key and email_address as the sort key. Perform a query operation on the GSI by using the begins_with key condition expression with the email_address property: This approach is correct. By creating a GSI with customer_type as the partition key and email_address as the sort key, the developer can efficiently query items based on customer_type. The begins_with condition can be applied to the sort key (email_address) in the GSI, allowing for searches that return partial matches.

The correct answer is (A). By adding a global secondary index (GSI) to the DynamoDB table with customer_type as the partition key and email_address as the sort key, the developer can perform a query operation on the GSI using the Begins_with key condition expression with the email_address property. This will return partial matches of all email_address properties of a specific customer_type.
