Exam AWS Certified Solutions Architect - Professional topic 1 question 82 discussion

Exam question from Amazon's AWS Certified Solutions Architect - Professional
Question #: 82
Topic #: 1
[All AWS Certified Solutions Architect - Professional Questions]

A company is running a batch analysis every hour on their main transactional DB, running on an RDS MySQL instance, to populate their central Data Warehouse running on Redshift. During the execution of the batch, their transactional applications are very slow. When the batch completes they need to update the top management dashboard with the new data. The dashboard is produced by another system running on-premises that is currently started when a manually-sent email notifies that an update is required. The on-premises system cannot be modified because is managed by another team.
How would you optimize this scenario to solve performance issues and automate the process as much as possible?

  • A. Replace RDS with Redshift for the batch analysis and SNS to notify the on-premises system to update the dashboard
  • B. Replace RDS with Redshift for the oaten analysis and SQS to send a message to the on-premises system to update the dashboard
  • C. Create an RDS Read Replica for the batch analysis and SNS to notify me on-premises system to update the dashboard
  • D. Create an RDS Read Replica for the batch analysis and SQS to send a message to the on-premises system to update the dashboard.

C is correct, since datawarehouse and traditional relational database is not the same thing. A data warehouse exists as a layer on top of another database or databases (usually OLTP databases). Addicionally not change database
