CompTIA A+ Core 2 (220-1102) — Question 485

Which of the following allows users to access connected system features through account federation?

Answer options

• A. MFA
• B. NAC
• C. SSO
• D. UAC

Correct answer: C

Explanation

The correct answer is SSO (Single Sign-On), which allows users to access multiple systems with one set of credentials, facilitating account federation. MFA (Multi-Factor Authentication) enhances security but does not provide access to features across systems. NAC (Network Access Control) manages device access to the network, and UAC (User Account Control) is a Windows feature that helps prevent unauthorized changes to the operating system.
