The work of an IT department is never finished. The WVCC network administrators and student assistants have many plans for the next network upgrade. Their main concern at this point is availability. Although the hierarchical mesh network has some redundancy, there are many single points of failure. Availability of applications can be adversely affected by any one of these points failing. Write a short paper that identifies the most significant single points of failure in WVCC's new network design. Discuss the changes to the network design that you would make (or additional products that you would recommend) to avoid these single points of failure.
