CCNA: Cisco Certified Network Associate — Question 59

An organization has decided to start using cloud-provided services. Which cloud service allows the organization to install its own operating system on a virtual machine?

Answer options

• A. platform-as-a-service
• B. network-as-a-service
• C. software-as-a-service
• D. infrastructure-as-a-service

Correct answer: D

Explanation

The correct answer is D, infrastructure-as-a-service, which provides virtualized computing resources over the internet, allowing users to install their own operating systems. Options A, B, and C do not offer the flexibility to install custom operating systems, as they are managed services where the provider controls the underlying infrastructure.
