Identify the solution with the lowest data transfer egress cost.
Explanation:
The correct answer is C: Host the visualization tool on premises and query the data warehouse directly over a Direct Connect connection at a location in the same AWS Region. Using AWS Direct Connect for data transfer between the on-premises environment and AWS can significantly reduce data transfer costs compared to using the internet, as Direct Connect provides a more predictable and lower-cost data transfer solution. Hosting the visualization tool on premises and leveraging the Direct Connect connection to query the AWS data warehouse ensures that the data transfer is within the same region, providing the lowest data transfer egress cost.
