Ch5 Flashcards
You, as a network engineer, have been sent to insert twisted pairs into an RJ-45 T568B for a newly set up network at Delta Innovations. Which of the following cables will you use in this scenario to connect the workstation to a switch?
Straight-Through Cable (Patch Cable)
Netcom Solutions is an Internet Service Provider that has purchased a fresh wholesale bandwidth from network service provider GT&P. Netcom Solutions has been using duplex technologies running through copper wires for its distribution. It now wants to upgrade to multiplexing technologies using fiber-optic cables so that it can allow multiple signals to travel simultaneously. Analyze which of the following types of multiplexing technologies Netcom should choose in this situation for its connection with GT&P so that it can operate with more channels.
DWDM (Dense Wavelength Division Multiplexing) or (Dense WDM)
A multiplexing technique used over single-mode or multimode fiber-optic cable in which each signal is assigned a different wavelength for its carrier wave.
You have successfully followed the cabling procedures for a new network connection at a primary school. The only task left is to connect the administrative computer to the console port of the router. Which of the following cables will you choose to connect the console port of the router to the computer?
Rollover Cable
Which of the following multiplexing types divides a channel into multiple intervals of time, or time slots?
TDM (Time Division Multiplexing)
A method of multiplexing that assigns a time slot in the flow of communications to every node on the network and , in that time slot, carries data from that node.
Which of the following multiplexing technologies would you use with fiber-optic cable?
WDM (Wavelength Division Multiplexing)
A multiplexing technique in which each signal on a fiber-optic cable is assigned a different wavelength, which equates to its own subchannel.
Josh is a new trainee at TT&P who has been sent to a client location to patch up cables connecting the switch to the data center. While doing so, Josh is unable to decide which connector to consider while connecting the ferrules of an SMF cable that measures 1.25 mm. Analyze and suggest which of the following connectors Josh should opt for under the circumstances so that there are minimum back reflections.
LC (Local Connector)
The most common 1.25-mm ferrule connector, which is used with single-mode, fiber-optic cable. Full-Duplex
Mr. Furland was hired as a network engineer at Secret Eye Corporations that is running a security camera outlet. While setting up a camera at one of the sites, he notices that the security camera has been mounted really high as a result of which there are no power receptacles to power up the device. So, Mr. Furland plans on powering these devices using an Ethernet cable. Which category of cable should he choose to power up the device?
Cat 7 (Category 7)
A twisted-pair cable that contains multiple wire pairs, each separately shielded then surrounded by another layer of shielding within the jacket, allowing throughput up to 100 Gbps at very short distances.
Cat 7 is not included in the TIA/EIA standards.
You are a network administrator for an ISP that wants to increase the amount of data that can be transmitted within the given bandwidth. For this purpose, you decide to use multiplexing technologies so that you can modulate the signals into different frequencies that can travel simultaneously over a single channel only to be demultiplexed at the other end. Which of the following multiplexing types will you use in this case?
FDM (Frequency Division Multiplexing)
A type of multiplexing that assigns a unique frequency band to each communications subchannel. Signals are modulated with different carrier frequencies and then multiplexed to simultaneously travel over a single channel.
Which of the following transceivers supports up to 10 Gbps?
XFP (10 Gigabit Small Form-Factor Pluggable)
A type of SFP that can send and receive data at rates of up to 10 Gbps.
SFP = Small Form-Factor Pluggable
RT&T is a world-renowned ISP that has hired you as a contractor for a cross-country network cabling project for its upcoming new FiberNet package. Through this package, it plans on providing high-speed Internet to consumers. Which of the following cables will you choose to carry out this large-scale project?
SMF (Single Mode Fiber)
A type of fiber-optic cable with a narrow core of 8 to 10 microns in diameter that carries light pulses along a single path from one end of the cable to the other.
While setting up a network segment, you want to check the functionality of a cable before putting connectors on them. You also want to measure the termination point or damage in the cable. Which of the following tools would you use to identify this?
Cable Performance Tester
A troubleshooting tool that tests cables for continuity, but can also measure crosstalk, attenuation, and impedance; identify the location of faults; and store or print cable testing results. Also called line tester, certifier, or network tester.
Mr. Anderson had to set up an Ethernet network segment that can transmit data at a bandwidth of 1000 Mbps and cover a distance of 2000 m per segment. The available fiber-optic cable in the market was an SMF cable. Analyze and discuss which of the following fiber Ethernet standards he should follow under such circumstances.
1000BASE-LX
A physical layer standard for networks that specifies 1-Gbps transmission over fiber-optic cable using baseband transmission. The LX represents its reliance on long wavelengths of 1300 nanometers.
Max trans bandwidth = 1000Mbps
Max distance = 550m MMF, 5000m SMF.
You are working as a network engineer for an ISP. A ticket has been raised that states that the SMF (single mode fiber) and the MMF (multimode fiber) cables have come apart at the FDP (fiber distribution panel). On checking the situation, you realize that you will need to melt the tips of the two fibers together so that light can pass cleanly through the joint. Which of the following kits will you require in this scenario?
Fusion Splicer
You are setting up a network connection that can transmit up to 10 Gbps with a maximum frequency of 500 MHz. However, you do not want to disrupt the previous cabling equipment as it will increase the cost. Which of the TIA/EIA 568 standard twisted-pair cables will you use to carry out this operation without having to go through the equipment changes?
Cat 6a (Augmented Category 6)
A higher-grade version of Cat 6 wiring that further reduces attenuation and crosstalk, and allows for potentially exceeding traditional network segment length limits.
The Embassy of New Zealand has hired you to set up some patch cables that are to be used at its immigration office. What color wire will you insert into the third pin of an RJ-45 plug in such an establishment?
White/Orange
