Identity Services and Access Frameworks for A+
Short answer
Identity services help systems know who a user is and what they can access. SSO is the user-facing result where one login covers multiple apps. SAML is one standard that enables identity assertions between providers and services. IAM refers to the broader policies and systems that manage identities and access. Directory services store identity records used by IAM and SSO systems.
Why it appears on the exam
- Match SSO to one-login access across apps, SAML to assertion exchange between systems, IAM to identity/policy management, and directory services to identity record storage.
Key concepts
Concept 1
Required terms
Security Assertions Markup Language (SAML): A standard used to exchange authentication and authorization assertions between an identity provider and a service provider. single sign-on (SSO): A sign-in experience where one authentication grants access to multiple connected services or applications. identity access management (IAM): A broad framework or set of tools for managing user identities, authentication, authorization, and access policies. directory services: Services that store, organize, and provide lookup for identity records, groups, and related attributes used in access decisions.
Example
An employee logs in once and can open several company cloud apps without separate logins -> SSO.
Concept 2
How Identity Services and Access Frameworks works
Identity services help systems know who a user is and what they can access. SSO is the user-facing result where one login covers multiple apps. SAML is one standard that enables identity assertions between providers and services. IAM refers to the broader policies and systems that manage identities and access. Directory services store identity records used by IAM and SSO systems.
Example
A company needs a central place to look up user groups and attributes -> directory services.
Concept 3
Common confusion
Learners often conflate SSO with SAML or treat IAM and directory services as identical. Emphasize: SSO is the experience, SAML is a supporting assertion standard, IAM is the overall management framework, and directory services store identity data.
Example
A support scenario that asks which standard exchanges authentication information between systems -> SAML.
Concept 4
Core 2 (220-1202) question cues
Match SSO to one-login access across apps, SAML to assertion exchange between systems, IAM to identity/policy management, and directory services to identity record storage.
Example
An employee logs in once and can open several company cloud apps without separate logins -> SSO.

Q1.A technician is troubleshooting this situation: An employee logs in once and can open several company cloud apps without separate logins -> SSO. What should they identify?
Q2.For this A+ objective, the scenario says: A company needs a central place to look up user groups and attributes -> directory services. What is the best match?
Q3.An A+ support scenario describes this situation: A support scenario that asks which standard exchanges authentication information between systems -> SAML. Which answer fits best?
