Question: What is the primary distinction between an orderly and disorderly departure of an Integrated Access Backhaul (IAB)-node from the network?
Option 1: The IAB-node's ability to maintain connectivity with neighboring nodes.
Option 2: The level of resource allocation required for the IAB-node's departure process.
Option 3: The impact on ongoing communication sessions between User Equipment (UE) and the IAB-node.
Option 4: Whether both the network and the IAB-node are aware in advance of the departure.
Explanation: An orderly departure implies that both the network and the IAB-node have prior knowledge of the departure, allowing for a more controlled and coordinated process. In contrast, a disorderly departure occurs without such prior awareness, often due to unexpected events like Radio Link Failure (RLF) with failed recovery.
