Which term is an emulation of a computing system?

• A. Dynamic Testing
• B. Entitlement
• C. Identity and Access Management (IAM)
• D. Virtual Machines

Answer: (D)

Emulation here means creating a software-based replica of a computer system that behaves like real hardware. A virtual machine does exactly that: it provides a complete guest computer with its own virtual CPU, memory, storage, and network interface, all managed by a hypervisor on real hardware. The guest operating system and applications run as if they’re on a separate physical machine, even though they’re actually sharing the host’s resources. The hypervisor maps the virtual resources to the host’s hardware, allowing multiple independent VMs to operate simultaneously. This makes virtual machines a classic example of emulating a computing system.

Dynamic Testing, Entitlement, and Identity and Access Management do not imitate an entire computer system. Dynamic Testing is about executing code to observe behavior, Entitlement deals with access rights, and IAM covers identity and access controls; none of these replicate a full hardware/software environment the way a virtual machine does.
