Question: In a 5G Network Resource Model (NRM), when multiple `DRACHOptimization` Managed Object Instances (MOIs) exist at different levels of the containment tree, how do their configurations interact?
Option 1: The `DRACHOptimization` MOI at the higher level of the containment tree always overrides those at lower levels.
Option 2: The `DRACHOptimization` MOI at the lower level of the containment tree overrides those at higher levels within the same containment tree.
Option 3: All `DRACHOptimization` MOIs at different levels must have identical configurations to avoid conflicts.
Option 4: The interaction between `DRACHOptimization` MOIs at different levels is determined by the network's overall Self-Organizing Networks (SON) policy.
Explanation: This is because, in a 5G Network Resource Model, when there are multiple instances of `DRACHOptimization` MOIs at different levels of the containment hierarchy, the instance at the lower level takes precedence. This ensures more specific configurations can override broader settings, allowing for finer-grained control over RACH optimization within the network.
