Question: What is the primary consideration for handling the VLR recovery procedure after an internal failure with restart, in relation to its impact on the network?
Option 1: Minimizing the time taken for the VLR to regain SGs association with all MMEs.
Option 2: Ensuring seamless handover of ongoing sessions to neighboring VLRs.
Option 3: Preventing overload problems due to increased signalling load on both the VLR and MMEs.
Option 4: Automatically triggering a global network restart to synchronize all elements.
Explanation: The correct answer highlights managing recovery to prevent overload issues, crucial as improper management could lead to a surge in signalling traffic, causing network instability or congestion. Prioritizing this prevents overload, maintaining network health and performance for the VLR and its associated MMEs.
