Certified Ethical Hacker (CEH v11) — Question 105

Which of the following is the structure designed to verify and authenticate the identity of individuals within the enterprise taking part in a data exchange?

Answer options

• A. SOA
• B. biometrics
• C. single sign on
• D. PKI

Correct answer: D

Explanation

PKI, or Public Key Infrastructure, is specifically designed to manage identity verification and authentication through digital certificates, making it the correct choice. SOA (Service-Oriented Architecture) relates to system design, biometrics involves physical traits but isn't a structured framework, and single sign-on is a convenience feature rather than a comprehensive identity verification structure.
