CompTIA Cloud+ (CV0-003) — Question 288

As part of a public cloud deployment strategy, the Chief Information Officer requires users to be able to log in to multiple cloud environments with a single identity. Which of the following is the best way to enable this method?

Answer options

• A. SAML federation with SSO
• B. Multifactor authentication
• C. VDIs in multiple cloud instances
• D. Lightweight directory access protocol

Correct answer: A

Explanation

SAML federation with SSO allows users to authenticate once and gain access to multiple cloud services, which meets the requirement for a single identity across environments. Multifactor authentication enhances security but does not facilitate single sign-on. VDIs in multiple cloud instances provide virtual desktop access rather than identity management, and Lightweight Directory Access Protocol is primarily for directory services, not for managing single sign-on across cloud platforms.
