An Ecommerce Company Has Tasked a Database Specialist with Creating

An ecommerce company has tasked a Database Specialist with creating a reporting dashboard that visualizes critical business metrics that will be pulled from the core production database running on Amazon Aurora. Data that is read by the dashboard should be available within 100 milliseconds of an update. The Database Specialist needs to review the current configuration of the Aurora DB cluster and develop a cost-effective solution. The solution needs to accommodate the unpredictable read workload from the reporting dashboard without any impact on the write availability and performance of the DB cluster. Which solution meets these requirements?

A) Turn on the serverless option in the DB cluster so it can automatically scale based on demand.
B) Provision a clone of the existing DB cluster for the new Application team.
C) Create a separate DB cluster for the new workload, refresh from the source DB cluster, and set up ongoing replication using AWS DMS change data capture (CDC) .
D) Add an automatic scaling policy to the DB cluster to add Aurora Replicas to the cluster based on CPU consumption.
