You are configuring a home entertainment system and need to choose the appropriate coaxial cable for connecCng to your television and also to your cable modem. Which of the following cable types should you consider for opCmal performance given the electrical characterisCcs menConed? A) RG-58 B) RG-59 C) RG-6 D) RG-8/U Answer: C) RG-6 Explana9on: RG-6 is recommended for home entertainment systems and for connecCons to cable modems, as it has beier electrical characterisCcs than RG-59, which is an older standard. RG-58 and RG-8/U are used for different applicaCons, such as networking in older 10BASE2 and 10BASE5 networks. Also, RG-58 and RG-8/U cables have a different impedance (i.e., 50 Ohms) as compared to RG-59 and RG-6 cables (i.e., 75 Ohms). Q2. You are installing a network in an office environment with a significant amount of electromagneCc interference (EMI). Which type of twisted pair cabling should you choose to ensure the best protecCon against EMI? A) UTP (Unshielded Twisted Pair) B) STP (Shielded Twisted Pair) C) Plenum-rated cabling D) Any twisted pair cabling, as they are all equally effecCve against EMI Answer: B) STP (Shielded Twisted Pair) Explana9on: STP (Shielded Twisted Pair) is the correct choice for environments with significant electromagneCc interference (EMI). STP cables have an addiConal layer of shielding, either foil or braided metal, which provides superior protecCon against EMI compared to UTP (Unshielded Twisted Pair) that relies solely on the twisCng of the wires. Plenum-rated cabling is concerned with fire safety and the release of toxic fumes, not specifically with EMI protecCon. © 2024 Kevin Wallace Training, LLC Q3. A network engineer is tasked with upgrading the company's network infrastructure to support 1 gigabit per second data transmission over a maximum distance of 100 meters. Which category of twisted pair cabling should the engineer choose to ensure compaCbility with the 1000BASE-T standard, while minimizing cost of the cabling? A) Category 5 B) Category 6a C) Category 3 D) Category 5e Answer: D) Category 5e Explana9on: Category 5e cabling is the appropriate choice for supporCng 1 gigabit per second data transmission over distances up to 100 meters using the 1000BASE-T standard. While Category 5 technically can support 1 gigabit per second, it's not recommended due to its electrical characterisCcs. Category 3 is not suitable for 1 gigabit per second speeds, and while Category 6a could also support 1 gigabit per second, however, it is more expensive that Category 5e. Q4. You are tasked with connecCng two PCs directly to facilitate a file transfer without using a switch or router. What type of Ethernet cable should you use to ensure the PCs can communicate effecCvely? A) Crossover cable B) Straight-through cable C) Plenum-rated cable D) Coaxial cable Answer: A) Crossover cable Explana9on: A crossover cable is required when directly connecCng two devices with idenCcal pinouts on their network interfaces, such as directly connecCng two PCs, to ensure proper communicaCon. This cable type swaps transmit and receive leads, allowing the devices to communicate effecCvely without needing an intermediary device like a switch. © 2024 Kevin Wallace Training, LLC Q5. When considering the installaCon of a fiber opCc network that spans a long distance, which type of fiber opCc cabling would you choose to minimize data corrupCon due to mulCmode delay distorCon? A) Coaxial Fiber B) Single Mode Fiber (SMF) C) MulCmode Fiber (MMF) D) Plenum-rated Fiber Answer: B) Single Mode Fiber (SMF) Explana9on: Single Mode Fiber (SMF) is the ideal choice for long-distance installaCons because it is designed to carry light directly down the fiber without mulCple modes of propagaCon. This characterisCc minimizes modal dispersion, a common issue in MulCmode Fiber (MMF) where different paths (modes) of light can lead to data corrupCon, especially over long distances. SMF has a smaller core diameter, allowing only one path for the light, which prevents modal dispersion and ensures data integrity. Q6. In secng up a high-density fiber network panel, which connector would you choose to maximize port density? A) ST connector B) LC connector C) SC connector D) MTRJ connector Answer: D) MTRJ connector Explana9on: The MTRJ connector is the best choice for maximizing port density in a high- density fiber network panel due to its design, which incorporates two fibers (for transmicng and receiving) within a single, very small connector. This allows for a higher density of cabling in the same physical space compared to ST, LC, and SC connectors, which typically require a separate connector for each fiber strand. © 2024 Kevin Wallace Training, LLC Q7. A network administrator is tasked with implemenCng a fiber opCc network to interconnect several buildings on a university campus, where the maximum distance between any two buildings does not exceed 220 meters. Also, the fiber network must support a speed of 1 gigabit per second. Which of the following Ethernet standards should the administrator choose to ensure compaCbility, while minimizing cost? A) 100BASE-FX B) 100BASE-SX C) 1000BASE-SX D) 10GBASE-LR Answer: C) 1000BASE-SX Explana9on: The 1000BASE-SX standard supports a 1 gigabit per second speed over 200m (using mulCmode fiber with a core diameter of 62.5μm). However, the 100BASE-FX and 100BASE-SX standards support a maximum speed of 100 megabits per second. The 10GBASE-LR standard supports a speed of 10 gigabits per second, but it uses single mode fiber, which is more expensive than mulCmode fiber. Q8. A network designer is planning to deploy IP cameras and wireless access points in a new office building. To simplify the installaCon and reduce the need for addiConal power outlets, which technology should be uClized to power these devices over the Ethernet infrastructure? A) Power over Ethernet (PoE) B) Power over Cable (PoC) C) Power Line CommunicaCon (PLC) D) Power over WiFi (PoWiFi) Answer: A) Power over Ethernet (PoE) Explana9on: Power over Ethernet (PoE) is the correct technology to use for powering devices like IP cameras and wireless access points over the Ethernet cabling. This technology allows electrical power, along with data, to be transmiied over Ethernet cables, eliminaCng the need for separate power supplies or electrical outlets close to the devices. © 2024 Kevin Wallace Training, LLC Q9. A network engineer noCces an increasing number of input/output errors on router interfaces. What could be a potenCal cause for these errors? A) Incorrect VLAN configuraCon B) Duplex mismatch C) IP address conflict D) Incorrect subnet mask Answer: B) Duplex mismatch Explana9on: Duplex mismatch is a common cause of increasing input/output errors on router interfaces. This occurs when one end of a connecCon operates in half-duplex mode and the other in full-duplex mode, leading to poor network performance and a high number of errors. A duplex mismatch can be diagnosed with the `show interfaces` command to view a router’s duplex secng and to look for conCnuously incremenCng errors. © 2024 Kevin Wallace Training, LLC
