A legacy municipal utility still authenticates line-of-business apps against on-premises Active Directory. Which identity concept does that describe?
Select an answer to reveal the explanation.
Short Explanation
Some city systems still check badges at the old local front desk—Active Directory on-premises. That is on-premises identity for those LOB apps. Cloud Microsoft 365 can sit beside it, but those apps still trust the local directory.
Full Explanation
On-premises identity refers to directories and authentication that remain hosted in local Active Directory Domain Services for workloads that have not moved to cloud identity. A legacy utility authenticating LOB apps against on-premises AD is a textbook on-premises identity scenario at MS-900 depth. Cloud-only identity would not use AD DS as the auth source; Purview DLP and Copilot Chat are not identity directory models.
