CompTIA Security+ (SY0-501) — Question 211

An organization wants to utilize a common, Internet-based third-party provider for authorization and authentication. The provider uses a technology based on
OAuth 2.0 to provide required services. To which of the following technologies is the provider referring?

Answer options

• A. Open ID Connect
• B. SAML
• C. XACML
• D. LDAP

Correct answer: A

Explanation

The correct answer is Open ID Connect, as it is built on top of OAuth 2.0 and is specifically designed for authentication. SAML, XACML, and LDAP are different standards and protocols that do not directly utilize OAuth 2.0 for their operations, making them incorrect choices in this context.
