CompTIA CASP+ (CAS-004) — Question 333

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 share access to applications without needing to merge their authentication systems, making it the best choice for this scenario. RADIUS and TACACS+ are protocols for remote authentication but do not facilitate cross-organization access. MFA enhances security but does not address the integration of different authentication stores, while ABAC focuses on access control policies rather than authentication methods.
