A network at a large building failed, causing a severe disruption in business activities. The problem was
eventually detected and resolved by replacing a piece of failed network equipment. Investigation led to the
conclusion that a network design problem was the main cause of the disruption. Loss of a single piece of
equipment should not have been able to cause such a large problem. What two terms best describe this type o
design weakness? (Choose two.)
