Selected Answer: B

Explanation: When upgrading a critical production application without a development environment, a quick rollback strategy is essential in case something goes wrong. Why Option B (Production Snapshot) is the Best Choice: ✔ Fastest rollback method – Snapshots capture the entire system state, including the OS, application, and configuration. If the upgrade fails, the administrator can quickly revert to the snapshot. ✔ Minimal downtime – A snapshot restore is significantly faster than restoring from a full or differential backup. ✔ Common cloud & virtualization feature – Many cloud platforms and virtualization solutions (e.g., AWS, Azure, VMware) provide snapshot-based rollback capabilities.
