Chapter 3 1. What is the most typical implementation of the hierarchal star? * All computers are connected to a single hub or switch. This is usually located in an equipment closet or telecommunications room 2. The loser cost method involves placing horizontal cross-connections and work group connections in the telecommunications room 3. Fiber to the telecommunication enclosure (FTTE) * Everything is run through a single point, * Odd are you paying more than you should be 1. The preferred UTP cabling media to support 10Gbps is Cat-5 or better. 2. Preferred Optical fiber to support 10Gbps is a single mode for long distance and multimode for short distance. 1. What Ethernet network application ports/modules should you use for horizontal links? -100Mbps for the horizontal, workgroups should have an uplink of 1Gbps 2. What are your horizontal cabling options? -Twisted pair (UTP), solid conductors copper cables, 62.5/125 micron and 50/125 micron multimode optical fiber 3. What backbone speed and network application should you use to obtain the lowest cost assuming a 10:1 rule? -Backbone speeds should be capable of operation at 10Gbps. It is smart to design the cabling with a 10:1 ration to support future bandwidth growth 4. What backbone cabling should you use? -UTP, ScTP, STP; 62.5/125 micron or 50/125 micron multimode optical fiber -You can also go with 8.3/125 micron single-mode optical fiber Chapter 5 1. What type of network cable would you use to connect the telecommunications room to the equipment room and what type of media would you specify inside the cable? -All in all, I would use Cat-5e to connect the telecommunication room to the equipment room. Over all, fiber optic, but it is expensive. Copper is still effective but not immune to EMI. So with coast in mind, copper would be the first
