Virtual machine (VM) configuration management (CM) tools should probably include ____________. Response:

Biometric recognition is an authentication method for user access, not a standard feature of VM configuration management tools themselves.

While security is important, 'anti-tampering mechanisms' is a broad term; specific logging and integrity checks are more direct features of CM for security rather than a general mechanism.

Log file generation is a fundamental feature for configuration management tools as it provides an audit trail of all changes, actions, and events performed on VM configurations. This is crucial for troubleshooting, compliance, security auditing, and understanding the state of managed systems.

'Hackback capabilities' refer to offensive security measures, which are entirely outside the scope and ethical boundaries of configuration management tools.
