Verified Boot is a security feature in ChromeOS that checks the integrity of the system during startup. It verifies that the firmware (low-level software) and the operating system haven't been modified or corrupted by unauthorized sources. If any tampering is detected, Verified Boot can initiate recovery processes to restore the system to a known good state.
Option B is incorrect because Verified Boot doesn't directly manage guest access.
Option C is incorrect because Verified Boot is a security layer that complements, not replaces, policy controls.
Option D is incorrect because website access control is handled by other mechanisms like web filtering or content restrictions.
