CompTIA Network+ N10-009 Practice Question

Biometric locks are the most effective option listed for controlling physical access to a sensitive area like a data center. They require unique physical characteristics (e.g., fingerprints or retinal patterns), which are harder to duplicate or share compared to key cards or pin codes. Traditional key locks are less secure as keys can be copied or stolen. Pin code access systems can also be compromised if the code is shared or observed by unauthorized persons. While surveillance cameras are useful, they do not prevent entry but rather record it, making them less effective as the primary security measure.
