Which statement best describes why virtualization is beneficial for lab environments?

• A. It guarantees 100% protection from all malware
• B. It allows running multiple isolated virtual machines on a single host for testing without extra hardware
• C. It replaces the need for network infrastructure
• D. It is primarily used for accelerating graphics rendering

Answer: (B)

Virtualization enables running several isolated virtual machines on one physical host, which is exactly what makes lab environments efficient. You can spin up different operating systems and configurations, test software, and perform experiments without purchasing extra hardware. Each VM is sandboxed, so changes in one don’t affect others, and you can quickly snapshot, roll back, or clone environments as needed. This combination of isolation, rapid provisioning, and consolidated hardware is what makes virtualization so valuable for labs. Other options miss the practical benefit: they don’t capture how virtualization enables multiple, separate test environments without extra gear, and they either overstate protection, ignore networking needs, or misstate the primary use.
