CompTIA SecurityX (CAS-005) — Question 32

Two companies that recently merged would like to unify application access between the companies, without initially merging internal authentication stores. Which of the following technical strategies would best meet this objective?

Answer options

• A. Federation
• B. RADIUS
• C. TACACS+
• D. MFA
• E. ABAC

Correct answer: A

Explanation

Federation allows different organizations to maintain their own authentication systems while enabling users to access shared resources seamlessly. RADIUS and TACACS+ are authentication protocols that do not provide a unified access solution without merging stores. MFA enhances security but does not address the integration of access between the two companies. ABAC focuses on access control based on attributes, which doesn't directly solve the unification of application access.
