Question: In the context of Service Enabler Architecture Layer for Verticals (SEAL), what is the basis for the functional model of identity management as per the 3GPP specifications?
Option 1: It is based on a dedicated vertical-specific architecture.
Option 2: It is based on the generic functional model specified in a broader architectural framework.
Option 3: It is derived from the identity management models used in previous network generations (e.g., 4G, 3G).
Option 4: It is exclusively designed for off-network identity management aspects.
Explanation: The functional model for identity management in SEAL is grounded in a pre-existing, broader architectural framework, ensuring consistency and integration with other aspects of the SEAL architecture, facilitating a cohesive support system for vertical applications' identity management needs.
