CCNA: Cisco Certified Network Associate — Question 305

Which security program element involves installing badge readers on data-center doors to allow workers to enter and exit based on their job roles?

Answer options

• A. physical access control
• B. biometrics
• C. role-based access control
• D. multifactor authentication

Correct answer: A

Explanation

The correct answer is A, physical access control, as it directly relates to managing physical entry points using mechanisms like badge readers. Option B, biometrics, refers to using biological traits for identification, which is not the focus here. Option C, role-based access control, pertains to permissions based on user roles but does not specifically address physical entry methods. Option D, multifactor authentication, involves using multiple verification methods but is also not directly related to physical access control.
