Question: What triggers a Packet Data Summary Report for a unique packet flow associated with an EPS bearer, according to security standards for lawful interception?
Option 1: Expiration of a configurable Summary Timer per intercept, reaching a per-intercept configurable count threshold, start/end of a packet flow, or interim report for a packet flow.
Option 2: Only when the target's data usage exceeds a predefined bandwidth limit within an EPS bearer.
Option 3: Upon detection of the first packet in a new EPS bearer, regardless of packet flow.
Option 4: Manually by the network administrator through a dedicated interface for lawful interception.
Explanation: This option correctly identifies all triggers for a Packet Data Summary Report as outlined in security standards for lawful interception. These include the expiration of a configurable Summary Timer, reaching a count threshold, and events related to the start or end of packet flows within an EPS bearer.
