Which of the following is NOT a best practice when performing cable management? A cable tester should be used to verify that each segment of cable is transmitting reliably. Cable should not be placed across a floor where they might be damaged by traffic. Cable ties should be pulled tightly to keep cables from moving around in a bundle. Grounding requirements should be followed when running cables.

What does a statement of work document do? -It documents in detail the work that must be completed for a particular object, and includes specifics such as tasks, deliverables, standards, payment schedule, and work timeline. -It documents the intentions of two or more parties to enter into a binding agreement, or contract, and is sometimes used between an informal handshake and the legally binding signatures on contracts. -It is 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, such as the service provided by an ISP. -It is a contract that defines the terms of future contracts between parties, such as payment terms or arbitration arrangements.

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

What statement regarding main distribution frame or main distribution facilities is accurate? -The MDF and entrance facility are always in separate rooms. -The MDF refers to the racks holding network equipment in an organization. -The MDF provides intermediate connection between the IDF and end-user equipment on each floor. -The MDF is the centralized point of interconnection for an organization's LAN or WAN.
The MDF is the centralized point of interconnection for an organization's LAN or WAN.
What does backbone cabling consist of? -Short length cables with connectors at both ends. -It is cabling that connects workstations to the closest data room and to switches housed in the room. -The cables or wireless links that provide interconnection between the entrance facility and MDF, and between the MDF and IDFs. -The shielded cables that are used for high data transmission rates between an organization and an ISP.
The cables or wireless links that provide interconnection between the entrance facility and MDF, and between the MDF and IDFs.
Why should you not leave more than 1 inch of exposed cable before a twisted-pair termination? -Exposing more cable than necessary can cause corrosion of the copper wire. -The exposure of the cable can cause transmission interference between wires. -The cable will lose its conductive properties. -The termination will fail over time due to oxidation.
