Question: When utilizing a notification service for a specific interface (e.g., Notification IRP: IS), what is the required setting for the order policy to ensure notifications are delivered in a specific sequence?
Option 1: RandomOrder - Notifications are delivered in a random sequence.
Option 2: LastInFirstOut (LIFO) - Newest notifications are delivered first.
Option 3: FifoOrder (First-in, First-out) - Oldest notifications are delivered first.
Option 4: PriorityOrder - Notifications are delivered based on their priority.
Explanation: To maintain a predictable and sequential delivery of notifications, the service must be configured to use FifoOrder (First-in, First-out). This setting ensures that the oldest notification in the queue is delivered first, crucial for maintaining chronological order and consistency in telecom network management.
