CompTIA Security+ (SY0-601) — Question 83

The concept of connecting a user account across the systems of multiple enterprises is BEST known as:

Answer options

• A. federation.
• B. a remote access policy.
• C. multifactor authentication.
• D. single sign-on.

Correct answer: A

Explanation

The correct answer is federation, which refers to the ability to connect user accounts across various systems and organizations. A remote access policy is related to access controls, multifactor authentication involves using multiple methods for verification, and single sign-on allows users to access multiple applications with one set of credentials, but does not necessarily imply cross-enterprise connectivity.
