Question: Under what condition(s) is interception for IMS (IP Multimedia Subsystem) Conference Services **NOT** necessarily initiated, according to security standards?
Option 1: When a target requests that a conference be created
Option 2: When the target of interception has not joined the conference but has provisioned or requested it
Option 3: During an ongoing conference when no parties have communication enabled by the conference server
Option 4: When only non-target parties are communicating within an already started conference, without the target's involvement
Explanation: Interception for IMS Conference Services is initiated based on a target's actions or involvement. However, if a conference is ongoing with only non-target parties communicating (without the target's direct involvement), interception specifically for IMS Conference Services would **NOT** necessarily be initiated, highlighting the focus on targeting specific individuals' communications.
