Hi everyone, I have recently completed my A+ course and have just started my N+.I am doing the properly sanctioned courses and also loads and loads of reading outside the box(which in truth is what is actually preparing me for my intended career).Thing is,that I find a lot of the questions Im asked when tested rely more on my guessing of how the writer has interpreted their own question,than my actual knowledge of the subject matter.So below,to prove the point to myself(with your expert help)and for you to see what they are teaching us these days,are two questions that I noted down while doing my last test.Please give your thoughts,because I think that not even the most skilled of you will be able to unravel the mysteries of at least the second question. (1) The most important feature of the OSI model is that it enables________ communications components to smoothly transport information packets. a. Diverse b. Similar c. Expensive d. Proprietary Now,is it a. Diverse - because it allows various vendors to all produce products that will work together when adhering to the OSI framework,but that will by default all be different in some ways from each other....and so, "diverse"? Or is it d. Proprietary - for pretty much the same reason? (2) The following exercise represents a real-world illustration of the OSI model. Match the sequence of steps of a voice telephone call to a business associate with whom you are confirming an appointment to the functional performance level of the OSI model. ________1. Physical Layer ________2. Data Link Layer ________3. Network Layer ________4. Transport Layer ________5. Session Layer ________6. Presentation Layer ________7. Application layer A. Dial tone B. Extension look up C. Telephone number D. Receptionist E. Modular telephone cord F. Confirming conversation G. "Please dial a 1......" Okay,so heres the problem.I dont think that many of us could arrange the lettered answers in order on their own,let alone match them with the OSI layers.And thats bad,because the question isnt actually testing whether you know and can arrange the OSI layers in their correct order because thats already done(allbeit from the receiving end).The question is actually testing whether you can arrange the phone call in the order that the question writer thinks it would take place.QAnd thats where it really makes no sense: Im confident that the "Modular telephone cord" represents the "Physical Layer",and that the "Telephone number" is the"Network Layer",and the "Dial tone" matches with the "Data Link Layer" as well as telling me that the order is from my end as the sender.So,whatever order the rest goes in it comes before the physical layer.Which must mean that in this "Real world example".....I am able to pick up my phone,dial a number and talk to someone,and all before any kinds of signals have travelled down my telephone cord. Figure that out?????? Thankyou for your time everyone who attempts this!! Yours John
