CompTIA Network+ (N10-008) — Question 789

A network technician is implementing a solution that will allow end users to gain access to multiple applications after logging on. Which of the following authentication methods would allow this type of access?

Answer options

• A. SSO
• B. LDAP
• C. EAP
• D. TACACS+

Correct answer: A

Explanation

The correct answer is A (SSO), which stands for Single Sign-On, allowing users to authenticate once and gain access to multiple applications. The other options, such as LDAP (B), EAP (C), and TACACS+ (D), are authentication protocols or directory services but do not provide the same seamless access across multiple applications after a single login.
