Question: In Intent-Driven Management Services for Mobile Networks, what does `targetAchievedValue` represent within the `TargetFulfilmentResult` data type for each `ExpectationTarget`?
Option 1: The reason for an infeasible status of an expectation target.
Option 2: The current performance value achieved for the expectation target.
Option 3: A boolean indicating whether the expectation target is fulfilled.
Option 4: The historical trend of performance values for the expectation target.
Explanation: Within the context of Intent-Driven Management, understanding the current state of network performance relative to set expectations (ExpectationTargets) is crucial. The `targetAchievedValue` specifically provides insight into how well an expectation is being met by detailing the current performance value. This allows for precise assessment and potential adjustment of network configurations or intents to better achieve desired outcomes, highlighting its role in practical telecom scenario management and optimization.
