Cable that is coated with flame-resistant polyvinyl chloride (PVC) is acceptable for use in plenum areas. True or False

The industry standard height for a rack in rack units is 42U. True or False

A 66 block is more suitable for data connections than the older 110 block. True or False

Fiber-optic cable comes in two types: single-mode fiber (SMF) or multimode fiber (MMF). True or False

In a rack setup, a device called a KVM allows multiple consoles to connect to a single device on the rack. True or False

When planning horizontal cabling, what is the maximum allowable distance that can be used? 1,000 feet 300 meters 100 meters 100 feet

In general, how much can a twisted-pair's cable be bent before data transmission may be impeded? 1-Twisted pair cable has a near infinite bend radius. 2-No more than ten times the diameter of the cable. 3-No more than two times the diameter of the cable. 4-No more than four times the diameter of the cable.

What statement accurately describes what a cable bend radius determines? 1-A cable bend radius is the radius of the maximum arc into which you can loop the cable without impairing data. 2-A cable bend radius defines the twist rate of the cable inside of the insulation. 3-A cable bend radius is the radius of the minimum arc into which you can loop the cable without impairing data. 4-A cable bend radius determines the total number of bends that can exist in an overall cable before data is impaired.

In order to ensure that a cable is not affected by electromagnetic interference, how far away should the cable be from fluorescent lighting? 1-at least 12 feet 2-at least 3 inches 3-at least 3 feet 4-at least 6 feet

What is NOT a TIA/EIA recognized cabling type that can be used for horizontal cabling? 1-unshielded twisted pair (UTP) 2-fiber-optic 3-RG-6 Coaxial 4-shielded twisted pair (STP)

What component of the backbone runs between a building's floors and can be used to connect an MDF and IDF or multiple IDFs? 1-diagonal cabling 2-patch cable 3-vertical cross connect 4-horizontal cross connect

Where is a demarc located in relation to the structured cabling of an enterprise environment? 1-in the Main Distribution Frame (MDF) 2-at the Intermediate Distribution Frame (IDF) 3-between the MDF and the IDF 4-in the work area

What component of enterprise level structured cabling serves as the location where an incoming network interface enters a building and connects with the building's backbone cabling? 1-network interface device 2-entrance facility 3-intermediate distribution frame 4-main distribution frame

During termination of twisted pair cabling, what should be done to ensure minimal cross talk is introduced? 1-Each pair should be twisted around another pair to reduce cross talk. 2-No less than 1 inch of the cable should be exposed. 3-No more than 1 inch of the cable should be exposed. 4-Each pair should be stripped of insulation so that it doesn't get caught in the jack.

What type of diagram is a graphical representation of a network's wired infrastructure? 1-system diagram 2-topology map 3-network diagram 4-wiring schematic

What is the name of the GUI front end that is available for the Nmap utility? 1-Zenmap 2-iMap 3-GUINmap 4-VizMap

What kind of document serves as a legally binding contract or part of a contract that defines, in plain language and in measurable terms, the aspects of a service provided to a customer? 1-memorandum of understanding 2-service-level agreement 3-statement of work 4-master service agreement

In a voice over IP setup (VoIP), what kind of device converts signals from a campus's analog phone equipment into IP data that can travel over a phone company's analog telephone lines? 1-VoIP MTA 2-VoIP PBX 3-VoIP translator 4-VoIP gateway

Why should you not leave more than 1 inch of exposed cable before a twisted-pair termination? 1-The exposure of the cable can cause transmission interference between wires. 2-The cable will lose its conductive properties. 3-Exposing more cable than necessary can cause corrosion of the copper wire. 4-The termination will fail over time due to oxidation.

What does backbone cabling consist of? 1-It is cabling that connects workstations to the closest data room and to switches housed in the room. 2-Short length cables with connectors at both ends. 3-The shielded cables that are used for high data transmission rates between an organization and an ISP. 4-The cables or wireless links that provide interconnection between the entrance facility and MDF, and between the MDF and IDFs.
