Question: Which interfaces are utilized by the MCData-6 reference point, situated between the MCData server and the EPS, for its operations in a Mission Critical Data (MCData) environment?
Option 1: MB2-C interface only, as defined for Group Communication System Enablers
Option 2: xMB-C interface only, specifically for file distribution purposes
Option 3: Both S1-AP and X2-AP interfaces, commonly used in EPS for signaling
Option 4: Both MB2-C interface (for multicast transport) and xMB-C interface (for file distribution)
Explanation: In the context of MCData, efficient resource allocation and data distribution are crucial. The correct answer reflects the utilization of both defined interfaces for specific purposes: MB2-C for requesting multicast transport resources (enabling group communications) and xMB-C for optimized file distribution, highlighting the nuanced application of these interfaces in supporting Mission Critical Data services within the EPS framework.
