Explanation

Server Virtualization Benefits in Data Centers

Virtualizing servers with VMs allows multiple virtual machines to run on a single physical server, which directly reduces the number of physical servers needed - meaning fewer rack units consumed, lower power draw, and less cooling infrastructure required (B). VM templates and snapshots also enable rapid provisioning of new servers in minutes rather than days or weeks compared to physical hardware deployment (D).

Why the distractors are wrong:

• (A) Increased security - VMs can actually introduce new attack surfaces (VM escape, hypervisor vulnerabilities); security is not a primary virtualization benefit
• (C) Reduced IP/MAC requirements - VMs typically increase IP and MAC address consumption since each VM needs its own addresses
• (E) Smaller Layer 2 domain - Virtualization doesn't inherently shrink broadcast domains; VLANs and network design control domain size, not VM count

Memory Tip: Think of virtualization in terms of physical resources saved (less hardware = less space/power/cooling) and time saved (deploy VMs instantly). The two benefits that are unique to virtualization and most commonly tested are consolidation and agility - matching options B and D respectively.
