During a malware-analysis lab, a technician needs to execute suspicious code without risking the physical PC or the production network. The technician launches a virtual machine that is fully isolated and will be discarded after the test is complete. According to CompTIA A+ virtualization concepts, which primary purpose of a virtual machine does this scenario illustrate?
Running potentially harmful software inside an isolated virtual machine keeps the host OS and network safe, providing a controlled sandbox environment. The sandbox purpose is specifically called out in the CompTIA A+ objectives as one of the key uses of virtual machines. The other options describe different virtualization use cases that do not fit the malware-testing scenario.
