Use these visual guides to connect the key ideas before answering the questions.

Choose a safe Linux labMatch the host situation to a route that protects valuable data and provides the needed isolation.
Choose a safe Linux labA decision connects a compatible Windows host to WSL 2, a cross-platform host to an Ubuntu VM, and a spare device to direct installation.
Choose lab routeStart with host risk and isolation needs
WSL 2Fast Linux shell on supported Windows
Ubuntu VMSeparate instance on a supported host
Spare deviceFull install after backup and checks
Create, verify, and recoverA usable lab joins repeatable creation with system evidence and a tested return path.
Create, verify, and recoverA flow moves from recorded creation through starting the lab and verifying identity to a tested recovery baseline.
