SK0-005 Question #461: Real Exam Question with Answer & Explanation

Question

Due to a disaster incident on a primary site, corporate users are redirected to cloud services where they will be required to be authenticated just once in order to use all cloud services. Which of the following types of authentications is described in this scenario?

Options

• AMFA
• BNTLM
• CKerberos
• DSSO

Explanation

The scenario describes Single Sign-On (SSO), where users authenticate once to access multiple cloud services without re-entering credentials.

Common mistakes.

• A. MFA (Multi-Factor Authentication) requires users to provide two or more verification factors to gain access, which enhances security but does not specifically enable single authentication for multiple services.
• B. NTLM (NT LAN Manager) is an older suite of Microsoft security protocols that provides authentication, integrity, and confidentiality to users, but it is not specifically designed for cross-service single sign-on.
• C. Kerberos is a network authentication protocol that grants users access to resources after a single authentication, but SSO is a broader concept that can encompass Kerberos or other protocols to achieve single sign-on across diverse services, especially in cloud environments.

Concept tested. Single Sign-On (SSO) authentication
