Administering Windows Server Hybrid Core Infrastructure (AZ-800) Practice

The key benefit of using checkpoints in Hyper-V is that they enable the rollback of changes. This feature allows administrators to capture the state, data, and hardware configuration of a virtual machine at a specific point in time. If an issue arises after changes are made—such as updates, installations, or configuration changes—administrators can revert the virtual machine to the state it was in when the checkpoint was taken. This is particularly valuable for testing scenarios or when making significant changes, as it provides a safety net that helps in quickly recovering from mistakes or failures without significant downtime.

While other options may imply benefits related to performance, storage, or networking, they do not capture the core purpose of checkpoints, which is fundamentally about preserving the virtual machine state and facilitating recovery to that state if necessary. This makes the ability to roll back changes a critical feature for maintaining the integrity and stability of virtual environments.
