Q4. The management functions discussed in this chapter pertain not only to the element management layer that deals with individual pieces of equipment, but really to any management layer. Give an example of a fault at the element management layer, an example of a fault at the network management layer, and an example of a fault at a service management layer.
Network management layer: Loss of connectivity between two devices—for example, cannot ping system A from system B
Service management layer: Degraded service—for example, for a voice service, no dial tone or excessive post-dial delay (time from dialing a phone number to hearing a ring tone)
Q5. Give an example of a configuration operation at the element management layer, a configuration operation at the network management layer, and a configuration operation at the service management layer.
