Which of the following would be the best ways to ensure only authorized personnel can access a secure facility? (Choose two.)

Badge access provides a verifiable method of entry, ensuring only individuals with valid credentials can unlock doors. This is a direct control over who enters. An access control vestibule, also known as a mantrap, enhances security by creating a two-door system where the first door must close before the second can open. This prevents tailgating and allows for individual verification of credentials, often combined with badge access, making it highly effective for restricting unauthorized entry. Video surveillance is a deterrent and a forensic tool, but doesn't directly prevent unauthorized access. Fencing defines a perimeter but can be breached. A sign-in sheet is easily circumvented and relies on honesty. Sensors detect presence but don't inherently control access.
