Correct answer: B. Hypervisor
Explanation
A Hypervisor (also called a Virtual Machine Monitor) is the software/firmware layer that abstracts physical server hardware and creates and manages multiple virtual machines (virtual servers) on it. A DNS server resolves names to IP addresses, a firewall filters traffic for security, and a load balancer distributes incoming requests across servers — none of these create virtual servers themselves.More Data Communication and Computer Networks questions
