Microsoft Azure Fundamentals — Question 257

You have an accounting application named App1 that uses a legacy database.
You plan to move App1 to the cloud.
Which service model should you use?

Answer options

• A. platform as a service (PaaS)
• B. infrastructure as a service (IaaS)
• C. software as a service (SaaS)

Correct answer: B

Explanation

The correct choice is B, infrastructure as a service (IaaS), because it provides the necessary infrastructure resources to host legacy applications and databases. PaaS (A) is more suited for developing new applications without managing the underlying infrastructure, while SaaS (C) is for fully managed software solutions, which is not applicable in this case.
