How can an administrator check the EVC mode for virtual machines when managing a cloud migration project?

The correct approach to check the EVC (Enhanced vMotion Compatibility) mode for virtual machines is found in the choice that involves selecting the host and viewing the VM settings directly related to EVC. By selecting the view of the host and then navigating to the VMs section, an administrator can use the Show/Hide Column feature to display the EVC Mode column. This method provides a straightforward overview of the EVC configuration that affects the virtual machines hosted on that particular host.

Understanding EVC is crucial during cloud migration projects, as it ensures compatibility among different CPU generations and allows for live migration of VMs without compatibility issues. The ability to visualize this information in a column format allows administrators to quickly audit and confirm EVC settings, which impacts VM performance and migration capabilities.

The other options focus on actions related to VM migration or configuration that are not directly intended for checking the EVC mode. Specifically, actions like changing storage or compute resources do not provide information about the EVC settings in use. Powering off the VM to configure EVC is also not practical for checking its currently set mode; it is more about setting or changing rather than verifying existing configurations.
