When defining extensible attributes in Cisco ISE, which option is required?

Defining extensible attributes in Cisco Identity Services Engine (ISE) involves several critical components, each playing an integral role in creating a robust and flexible system for identity management. When you are tasked with defining these attributes, it’s essential to provide the attribute name, attribute type, and data source.

The attribute name is necessary because it specifies the identifier for the attribute, allowing users to understand its purpose and context. The attribute type is required as well because it decides what kind of data can be stored in that attribute, such as string, integer, or boolean, ensuring that the information is interpreted correctly when processed by the system.

Furthermore, the data source is also mandatory as it determines where the information for that attribute is drawn from, whether from external databases, internal directories, or other repositories. This linkage to the data source is crucial for maintaining consistency and accuracy in identity management.

Therefore, all these components must be specified when creating extensible attributes in ISE to ensure that they function correctly within the broader context of identity and access management. Each part contributes to a comprehensive understanding and functioning of the attribute, making them collectively required for successful implementation.
