What operations can be performed on a Windows virtual machine in Huawei FusionCompute experiencing a blue screen?

The correct choice is based on the capabilities of Huawei FusionCompute when dealing with a virtual machine that experiences a blue screen. In such a scenario, taking a snapshot can be a key recovery strategy. Snapshots capture the state of the VM at a specific point in time, which can be critical for troubleshooting and restoring the system to a functional condition without losing previous data.

High Availability (HA) features allow for automatic recovery of VMs in case of failures, including those that might result from a blue screen error. This means that FusionCompute can attempt to recover the VM automatically or through administrative intervention to restore its operation without the need for extra manual tasks.

Other operations such as restarting the virtual machine or formatting it are more drastic measures that might result in data loss or additional complications. While shutting down or deleting a virtual machine are possible actions, they do not aid in recovering from the blue screen error and are not suitable first steps for troubleshooting in this context. Similarly, restoring from a backup could be an option but is not always effective immediately, especially if the blue screen indicates a software issue requiring a more nuanced approach like using snapshots.

Thus, the focus on snapshot recovery and HA aligns best with effective and safe recovery operations in the face of a blue screen
