NEW QUESTION # 207
Drag and drop the alarm slates from the left onto the corresponding alarm descriptions on the right.
Answer:
Explanation:
* Critical (Red): events that impair overlay network function
* Major (Yellow): events that might impair performance of network
* Medium (Blue): events that affect operation of network function
* Minor (Green): events that might diminish performance of network
* Critical (Red): These are the highest severity alarms indicating events that can cause significant impairment to the overlay network's functionality. Immediate attention is required to prevent major network issues.
* Major (Yellow): These alarms indicate events that could potentially impair network performance. They are serious but not as critical as red alarms. They need prompt attention to prevent degradation in network performance.
* Medium (Blue): These alarms are of medium severity and indicate events that affect the operation of the network function. They are important but do not require immediate action.
* Minor (Green): These are the lowest severity alarms and indicate events that might diminish network performance. They are more informational and do not typically require urgent action.
