Correct answers: A, D
Explanation
This scenario requires a combination of cloud models and services to meet the company's needs. PaaS is ideal for developing and hosting customer-facing applications, as it provides tools and runtime environments. SaaS is well-suited for email services because it is fully managed and easy to deploy. For financial data, a private cloud ensures maximum security, but a hybrid cloud can also offer flexibility by combining private and public cloud benefits.
- A. Correct.
Correct: PaaS is ideal for hosting customer-facing applications as it provides tools and runtime environments for development. SaaS is suitable for email services, and a private cloud ensures sensitive financial data remains secure.
- B. Incorrect.
Incorrect: IaaS requires more management and may not provide the development tools needed for the application. Public clouds are not ideal for sensitive financial data due to potential security risks.
- C. Incorrect.
Incorrect: SaaS is not suitable for hosting a custom customer-facing application that requires development tools. Hybrid clouds could work for financial data, but this option does not provide the best setup overall.
- D. Correct.
Correct: PaaS supports application development and hosting, SaaS is appropriate for email services, and a hybrid cloud offers flexibility for handling financial data securely.
