What does virtualization do?

• A. Virtualization creates virtual resources to run multiple environments on a single hardware platform.
• B. Virtualization is a type of database indexing method.
• C. Virtualization is a data backup technique.
• D. Virtualization is a programming language.

Answer: (A)

Virtualization is about turning physical hardware into virtual resources so a single computer can host multiple independent environments at once. By carving up CPU, memory, storage, and network resources into separate virtual machines, you can run different operating systems or applications in isolation on one physical host. This enables consolidation, easier testing, and flexible deployment without needing extra hardware. The other options describe databases indexing, data backups, or a programming language—concepts that address different aspects of computing and are not what virtualization does. So, virtualization creates virtual resources to run multiple environments on a single hardware platform.
