Best answer: "One bad configuration could be replicated across your network."

Why: VMs are easy to clone, snapshot, and deploy from templates. A misconfigured image or vulnerable template can be propagated quickly to many hosts, multiplying risk. Also virtualization concentrates many workloads on a single physical host and relies on a hypervisor — so a compromise or misconfiguration can affect multiple VMs. The other statements are not primary reasons:
- Performance differences vs physical networking devices isn’t the main security concern.
- "Starts a minimal OS for a remote user" describes a use case, not why VM security is more important.
- "There is a limited amount of work that can be done on one host" is incorrect — hosts often run many VMs, increasing blast radius.
