正解:A,C,D
Virtualization provides several well-documented benefits in modern IT environments. One major advantage is improved hardware utilization(A), as multiple virtual machines can run on a single physical system, maximizing resource usage. Virtualization also enhancessecurity(C) through isolation between workloads, limiting the impact of failures or security breaches.
Another key benefit issimplified backup and recovery(D). Virtual machines are encapsulated into files, making it easier to snapshot, back up, clone, and restore entire systems. This significantly improves disaster recovery and testing workflows.
Option B is not universally true. While virtualization can help standardize environments, it does not inherently reduce software compatibility issues; in some cases, it may even introduce additional layers of complexity.
Virtualization documentation consistently highlightshardware efficiency, security isolation, and operational flexibilityas core benefits, makingA, C, and Dthe correct answers.
