Question: What triggers the activation of a Performing Service State Machine (SSM) in the context of MAP specific services?
Option 1: Receipt of a MAP response primitive with a linked identifier
Option 2: Arrival of a TC-INVOKE indication primitive with a linked identifier
Option 3: Arrival of a TC-INVOKE indication primitive without a linked identifier
Option 4: Sending of a MAP specific request primitive to another node
Explanation: A Performing Service State Machine (SSM) is activated upon receiving a TC-INVOKE indication primitive that does not have a linked identifier, distinguishing it from other primitives or events that may trigger different actions within the service state management.
