Question: In a Public Land Mobile Network (PLMN), a video streaming service from a server to a User Equipment (UE) is characterized by which symmetry attribute, considering the primary direction of information flow?
Option 1: Bidirectional Symmetric
Option 2: Unidirectional
Option 3: Bidirectional Asymmetric
Option 4: Not Applicable to PLMN Services
Explanation: Since the primary direction of information flow in a video streaming service is from the server to the UE (with minimal feedback from the UE, such as playback controls), this scenario is best described as unidirectional. The information flow is predominantly in one direction, from the server to the UE, making bidirectional attributes less fitting for this specific use case's primary characteristic.
