Question: What is the primary purpose of the 'Random Time Period' in the context of Multimedia Broadcast/Multicast Service (MBMS) file repair procedure?
Option 1: To ensure a statistically uniform distribution of file repair initiations over a specified time window, preventing network congestion.
Option 2: To set a fixed delay for all MBMS clients before initiating file repair, ensuring synchronized network requests.
Option 3: To define the maximum duration an MBMS client should wait before abandoning a file repair attempt.
Option 4: To specify the frequency at which MBMS clients should poll the network for updated content.
Explanation: The 'Random Time Period' ensures a statistically uniform distribution of file repair initiations, preventing sudden spikes in network traffic (congestion) that could occur if all clients initiated repairs simultaneously. This differs from fixed delays, abandonment timelines, or polling frequencies, which aren't aligned with its described functionality.
