Question: What are the three options of Network Slice Admission Control (NSAC) procedures defined for an S-NSSAI, depending on the NSAC architecture deployed in the network?
Option 1: Hierarchical NSAC architecture only
Option 2: Centralized and non-Hierarchical NSAC architectures only
Option 3: Non-Hierarchical, centralized, and hierarchical NSAC architectures
Option 4: Only one option is defined for all NSAC architectures
Explanation: The three options of Network Slice Admission Control (NSAC) procedures are defined as non-Hierarchical, centralized, and hierarchical NSAC architectures. These options provide flexibility in deploying NSAC procedures depending on the network architecture.
