Which two benefits result from server virtualization using VMs in a data center?

Server virtualization allows multiple virtual machines (VMs) to run on a single physical server. This consolidates workloads, leading to a significant reduction in the number of physical servers needed. Fewer physical servers directly translate to less rack space consumed, lower power consumption, and reduced cooling requirements in the data center. Additionally, VMs can be provisioned and deployed much faster than physical servers, as they are software-defined and can be cloned or templated, enabling speedy deployment of new services or applications. "Smaller Layer 2 domain" is incorrect because virtualization can actually increase the complexity of the Layer 2 domain within the hypervisor. "Increased security" is not a direct benefit; while virtualization offers some security features, it also introduces new security challenges. "Reduced IP and MAC address requirements" is incorrect as each VM still requires its own IP and MAC address.
