Physical Network Segmentation 1. What is a demarc point? A demarc point is actual place where authority or responsibility for the network is transfers from one party to the next. 2. What is the significance of a demarc point? The significance of a demarc point is the special place that is responsible for the internet connection or telephone line from within the building. So basically, demarc point decide where the responsibility is passed from a provider to the customer. 3. What is a Main Distribution Frame? A Main Distribution Frame is where all the cables come together to create the overall network. 4. What is an Intermediate Distribution Frame? An Intermediate Distribution Frame is a middle-ground connection center between the office space and the MDF. 5. Why use an IDF? Using an IDF it is easier to make a connection to the MDF. Also, you would only need to run one cable from the IDF to the MDF, instead of running 50+ cables from your office space to the MDF. 6. In a conventional small network, where would you expect to find the MDF? In a conventional small network, you would expect to find the MDF in the server room. 7. If you had a network that covered five floors in a building, how many IDF(s) and MDF(s) would you expect to have? If you had a network that covered five floors in a building, you would expect to have 1 MDF on the 1st floor and 4 IDF(s) on the other 4 floors. 8. What purpose does an IDF serve? The purpose of an IDF is to make it easier and cost effective to connect to the MDF. Let say you have a company that has multiple floors in a building or they have multiple buildings that all need to connect to the network. An IDF can be used as a switch for each floor or each separate building where all the machines are connecting to. The IDF’s are then connected, usually through Fiber optic cabling, to the MDF location.
