assalam alaikum
sir there is a conflict about the qn 4 or 3 (for choosing the optimum route,,write about the performance criteria of routing strategy) among students....most of them say the right answer is to discuss or list the characteristics of the routing strategy...i.e about rhobustness and stability..
whereas the book categorises all this as the CHARACTERISTICS not PERFORMANCE CRITERIA..the performance criteria is to write about the selecting the optimum routestrategy such as the least cost route or the minimum hope route....this is in the william stalling book..
sir i wrote my answer in the least cost and minimum hop routes sense since the qns asked us to write about optimum route...
sir please mark this question lineantly and donot deduct marks for this qn.i wrote the book answer...every quiz counts for us now..
thanks a lot for your time sir
