CompTIA Network+ (N10-007) — Question 518

A network administrator wants to reduce the amount of time each user takes to log in to different systems in the network. Which of the following would reduce the time spent authenticating?

Answer options

• A. Kerberos
• B. RADIUS
• C. Certificate
• D. SSO
• E. MFA
• F. NAC

Correct answer: D

Explanation

Single Sign-On (SSO) allows users to authenticate once and gain access to multiple systems without needing to log in separately to each one, effectively reducing login time. While Kerberos and RADIUS are authentication protocols, they don't provide the same user experience as SSO in terms of convenience. Certificates, MFA, and NAC also enhance security but do not primarily focus on reducing login time.
