      117 Ralph has been hired by a client to install cabling to connect two existing networks. The two networks are in different buildings approximately 1000 feet apart. The cable type must support Gigabit Ethernet data rates of 1000 megabits per second (Mbps) and provide a high level of resistance to electromagnetic interference (EMI). Your client wants the most economical cabling solution that meets their needs. Which of the following cable types best meets the needs of this client?Multimode fiber-optic cableShielded Twisted Pair (STP) cableUnshielded Twisted Pair (UTP) cableThin coaxial cableSingle-mode fiber-optic cable

      118 Which of the following are connector types used with coaxial cables? (Choose all that apply.)BNCF-typeN-typeSTRJ-11

      119 Alice has been hired by a corporation to design the cabling for their network. The corporation just moved into two different floors of an older building: a retail space on the ground floor and an office space on the 43rd floor. The building has existing Category 5 (CAT5) Unshielded Twisted Pair (UTP) cable. Alice's client wants two separate Local Area Networks (LANs), one on each of the two floors, with a backbone network connecting them. They want a 1 gigabit-per-second (Gbps) data rate for each LAN but plan on migrating to 10 Gbps in the future. The two networks are approximately 200 meters apart. Which of the following solutions best meets the client's needs?Install Category 6 (CAT6) or Category 6a (CAT6a) UTP cable for the LANs. These cables run at 1 Gbps and provide a migration path to 10 Gbps. Use twisted pair cable for the backbone network.Use the existing CAT5 cabling for the LANs, since CAT5 runs at 1 Gbps. Use thick coaxial cable for the backbone network.Install CAT6 or CAT6a UTP cable for the LANs. These cables run at 1 Gbps and provide a migration path to 10 Gbps. Use multimode fiber-optic cable for the backbone network.Install CAT6 or CAT6a UTP cable for the LANs. These cables run at 1 Gbps and provide a migration path to 10 Gbps. Use the existing CAT5 cable for the backbone network.

      120 A maintenance worker, while replacing a light fixture in an office building, accidentally severs a network cable in the drop ceiling. The tenants use a variety of Local Area Network (LAN) technologies throughout the structure, but on that particular floor, there are three separate LANs: a 10-node Thin Ethernet LAN using coaxial cable in a bus topology, a 25-node Gigabit Ethernet LAN using twisted pair cable in a star topology, and a 5-node Fiber Distributed Data Interface (FDDI) LAN using multimode fiber-optic cable in a double ring topology. Without knowing which of the LANs the severed cable belongs to, what is the maximum number of computers that could be directly affected by the cable break?015102540

      121 In the punchdown process for Unshielded Twisted Pair (UTP) cable, which of the following is the last step that you perform when connecting bulk cables to jacks in wall plates and patch panels?Cut off the excess wire that protrudes past the contacts.Press the bare wire down between the two metal contacts that hold it in place.Strip some of the insulating sheath off the cable end to expose the wires.Insert the wires into the appropriate contacts in the jack.Strip a small amount of insulation off each wire.Separate the twisted wire pairs at the ends.

      125 Which of the following twisted pair cable types is rated for both a 10-megabit-per-second (Mbps) data rate (using two pairs) and a 100 Mbps data rate (using four pairs)?Category 3 (CAT3)Category 5 (CAT5)Category 5e (CAT5e)Category 6 (CAT6)

      126 Ed has been hired to install network cabling for a small private company with 15 employees who need to share files and printers. All of the employees are physically located within the same building in two separate office spaces directly adjacent to each other, sharing a common wall and door for access. Both offices have drop ceilings. The client wants a simple Gigabit Ethernet installation that is easy to troubleshoot. In addition, Ed's client wants to keep installation costs to a minimum. Which of the following combinations of topology, cable type, and installation method would best meet the needs of Ed's client?Star topology, fiber-optic cabling, and internal installationBus topology, coaxial cabling, and external installationBus topology, twisted pair cabling, and internal installationStar topology, coaxial cabling, and external installationStar topology, twisted pair cabling, and external installation
