in the Main Distribution Frame (MDF)
Where is a demarc located in relation to the structured cabling of an enterprise environment? in the Main Distribution Frame (MDF) at the Intermediate Distribution Frame (IDF) at the entrance facility between the MDF and the IDF
full-duplex
Which method of transmission allows signals to travel in both directions over a medium simultaneously? half duplex simplex full-duplex multiplex
iSCSI
If the use of a pre-existing Ethernet infrastructure is desired for a SAN, what Transport Layer protocol should be utilized? Fibre Channel iSCSI SAS PATA
Fiber optic
What cable type comes in two different modes, single mode and multimode? UTP STP Fiber optic Coaxial
vertical cross connect
What component of the backbone runs between a building's floors and can be used to connect an MDF and IDF or multiple IDFs? horizontal cross connect patch cable vertical cross connect diagonal cabling
No more than 1 inch of the cable should be exposed.
During termination of twisted pair cabling, what should be done to ensure minimal cross talk is introduced? No more than 1 inch of the cable should be exposed. No less than 1 inch of the cable should be exposed. Each pair should be stripped of insulation so that it doesn't get caught in the jack. Each pair should be twisted around another pair to reduce cross talk.
