EMC Proven Professional – Cloud Architect — Question 25

You are designing a cloud services architecture for a company. You have determined that running some of the customer facing applications the company uses in a public cloud would save a significant amount of money but the security department wants to retain control of customer data at rest. The application infrastructure consists of two database servers and eight web servers.
How can you architect the application to minimize the risk involved with data exposure?

Answer options

• A. Host the application servers in the public cloud and host the databases in the private cloud.
• B. Scale the application horizontally by utilizing a hybrid cloud where the application and database are mirrored a public cloud.
• C. Cluster four of the application servers and one database server in the public cloud and the remaining servers in the private cloud.
• D. Host the application servers and database servers in the public cloud and set up RBAC to restrict access to the applications

Correct answer: A

Explanation

The correct answer is A because it allows the application servers to benefit from the cost-effectiveness of the public cloud while keeping sensitive customer data secure by storing it in the private cloud. Options B and C increase the risk of data exposure by mirroring or clustering in the public cloud, while option D does not address the core concern of retaining control over data at rest.
