AWS Certified Data Analytics – Specialty DAS-C01 – Question083

A retail company that is based in the United States has launched a global website. The website's historic transaction data is stored in an Amazon Redshift cluster in a VPC in the us-east-1 Region. The company's business intelligence (BI) team wants to enhance user experience by providing a dashboard to visualize trends.
The BI team decides to use Amazon QuickSight to render the dashboards. During development, a team in Japan provisioned QuickSight in the ap-northeast-1 Region. However, the team cannot connect from QuickSight in ap-northeast-1 to the Amazon Redshift cluster in us-east-1.
Which solution will resolve this issue MOST cost-effectively?

A.
In the Amazon Redshift console, configure Cross-Region snapshots. Set the destination Region as ap-northeast-1. Restore the Amazon Redshift cluster from the snapshot. Connect to QuickSight in ap-northeast-1.
B. Create a VPC endpoint from the QuickSight VPC to the Amazon Redshift VPC.
C. Create an Amazon Redshift endpoint connection string with Region information in the string. Use this connection string in QuickSight to connect to Amazon Redshift.
D. Create a new security group for the Amazon Redshift cluster in us-east-1. Add an inbound rule that allows access from the appropriate IP address range for the QuickSight servers in ap-northeast-1.
