What does Fast Ethernet (100BASE-TX) use to support older 10BASE-T Ethernet interfaces?
Autonegotiation
Full-duplex transmissions
Higher frequency signaling
Use of hubs instead of switches
What is the main advantage of using fiber optic cable over copper cable?
Heavier and more durable for outdoor use.
Higher bandwidth and faster data transmission over longer distances.
Switches eliminate the effect of contention by using what type of transmissions?
What does 10BASE-T network cabling denote?
100 Mbps Ethernet, uses a baseband signal, and runs over twisted pair cabling.
1 Mbps Ethernet, uses a baseband signal, and runs over fiber optic cabling.
10 Mbps Ethernet, uses a baseband signal, and runs over twisted pair cabling.
10 Gbps Ethernet, uses a baseband signal, and runs over coaxial cabling.
What are the typical uses of RG-59 coax cable?
Typical uses of RG-59 coax cable include CCTV systems, audio/ video connections.
Typical uses of RG-59 coax cable include internet networking, wireless communication.
Typical uses of RG-59 coax cable include high-frequency data transmission, long-distance audio connections.
What type of cable must you use when running cable through a false ceiling or a raised floor?
Plenum-rated cable
Why are wires twisted together in twisted pair cables?
How can you tell the difference between RJ11 and RJ45 connectors?
RJ11 connectors have 4 or 6 pins/are used for telephones, while RJ45 connectors have 8 pins, a plastic retaining clip/are used for Ethernet.
RJ11 connectors are larger and used for network connections.
What is the main function of horizontal cabling?
The main function of horizontal cabling is to connect work areas to the IDF.
When using copper cabling, what is the maximum distance between the IDF and each wall port?
The IDF must be within 200 m cabling distance of each wall port.
The IDF must be within 90 m cabling distance of each wall port.
The IDF must be within 150 m cabling distance of each wall port.
The IDF must be within 50 m cabling distance of each wall port.
What is the most likely impact of installing cable runs that are in close proximity to several electrical power cables and fluorescent lights?
When installing structured cabling, why is it important to leave a service loop at both ends of the cable run?
It allows for faster installation and reduces costs.
It leaves slack at both ends to make the connection and to accommodate future reconnections or changes.
Which tool is used to create a patch cord by fixing a plug to a cable?
Cable Crimper
Which fiber optic connector is known for its small form factor and is widely adopted for Gigabit Ethernet and 10/40 GbE?
MTRJ
ST
What is the primary purpose of using fiber distribution panels in a fiber optic network?
Which fiber optic cable has a smaller core, but a long wavelength and provides better support for 40 Gbps and 100 Gbps data rates?
Twisted Pair Cable
Coaxial Cable
Single Mode Fiber
Multimode Fiber
How is each network appliance and server hardware installed in a rack if there is little need for maintenance?
Each appliance can be screwed into the rack directly. A tower server or monitor, can be installed on shelves.
What electrical device will convert the DC power stored in batteries into AC power that can be used by devices?
What do internal sensors within servers and appliances normally monitor?
Security breaches
Software updates
Component Failure
Fan speed
Temperature
For a rack containing equipment that draws 2000 watts in total on a 240 VAC circuit, what is the amperage?
How can you identify transmitted optical signals when working with fiber optic patch cords?
Transmitted optical signals are visible as bright white spots when viewed through a smartphone camera.
What is the maximum distance supported by Cat 6A cables?
What does Alien Crosstalk measure?
Interference from cables that are in close proximity.
What is the primary consequence of connecting single mode fiber to multimode fiber?
Catastrophic signal loss of up to 99%
What is the first step in troubleshooting cable issues?
Check physical damage.
What is the main purpose of using a hot aisle/cold aisle layout in a data center?
