Why is it important and difficult to maintain connectivity in a network?

What will be an ideal response?

This should be a general discussion.Encourage discussion of both aspects: importance and difficulty.The importance is to maintain network operation and interconnectivity of any two hosts on the same network; although the actual use of these connections may vary, it is important to guarantee operations as detailed in the network configuration.Another important consideration in managing a network is the quality of service (QoS) metrics discussed in previous chapters such as availability.The difficulty in managing a network is that most of the network itself is generally difficult to access, namely the cabling connecting the nodes.This can run through walls, under floors, or even across ceilings.It may even be outside of the property of the organization maintaining the network.Understanding the jurisdiction and responsibility of managing elements of the network is essential for managing it.
