Assignment directions the owner of a popular local coffee shop has approached you to design a network for his business. he would like to offer his customers wifi access to the internet, but also thinks it might be handy to network the kitchen and store room together with the office computer he already uses for ordering, scheduling, and payroll. he thinks that might save him time doing inventory control and ordering. your assignment is to create a set of questions for him that will precisely define the purpose of the network and any constraints and restrictions on its implementation. assignment guidelines create a list of at least ten questions to ask your customer. of those ten questions, at least one question must come from each of the following subject areas: purpose of the network network access and security issue network availability and fault tolerance issues future expansion issues vendor issues briefly explain in two or three sentences why you would ask each question and what you expect to learn from your customer’s response. submission requirements your questions should meet the criteria of a good survey question by being specific, unambiguous, and closed-ended. all questions, as well as your explanations, should be written in proper english using correct grammar, spelling, and punctuation. use complete sentences, and do not use slang, texting abbreviations, or shortcuts.
