CompTIA Security+ (SY0-701) — Question 190

A company is decommissioning its physical servers and replacing them with an architecture that will reduce the number of individual operating systems. Which of the following strategies should the company use to achieve this security requirement?

Answer options

• A. Microservices
• B. Containerization
• C. Virtualization
• D. Infrastructure as code

Correct answer: B

Explanation

Containerization allows multiple applications to run in isolated environments using a single operating system kernel, significantly reducing the number of individual operating systems needed. Microservices, while beneficial for application structure, do not directly address the operating system reduction. Virtualization enables multiple OS instances but does not minimize them as effectively as containerization. Infrastructure as code focuses on managing infrastructure through code but does not impact the number of operating systems directly.
