Which term describes virtualization that uses storage area network (SAN) technology to pool storage for multiple virtual machines?

• A. Storage Virtualization
• B. Fabric Virtualization
• C. File System Virtualization
• D. Server Virtualization

Answer: (A)

Storage virtualization pools storage resources using SAN technology to present a single, scalable pool to multiple virtual machines. By abstracting the physical disks and arrays from how they’re consumed, administrators can allocate storage on demand to any VM, optimize utilization, and simplify management. SAN provides fast, block-level access across devices, making it ideal for sharing storage among many VMs and enabling features like thin provisioning and centralized control without tying each VM to a specific disk. The other terms describe different ideas. Fabric virtualization relates to the network fabric itself rather than storage resources; file system virtualization focuses on a virtualized view of files or namespaces rather than pooling block storage; server virtualization centers on abstracting compute resources (CPU, memory) for multiple VMs and doesn’t specifically address pooling storage via SAN.
