1. You are in charge managing the performance of your organisation's network. What are the metrics you should check to assess performance? Discuss each by providing a practical example. [2 Marks] 2. A section of a network you manage contains two routers (router 1 and router 2) connected with two redundant links. lCine of the links A336 reliable while the second link is CD36 reliable. Where A, B, C and D are the last nonzero forur digits of your students ID. For example if your student ID is s1234067, then D=7, C=E,B=4 and A=3 hence A1 = 34% and A2 = 67%. [2 Marks] a. Calculate the overall reliability of the section of the network between these routers. Clearly show your working. [1 mark] h. Explain the implication of your answer for part (a) in regards to the link between router 1 and router 2. [1 mark]
