How do GG45 connectors compare to RJ45 connectors?
How do GG45 connectors compare to RJ45 connectors?
GG45 connectors have a similar form factor to RJ45, but with additional conductors in the corners.
How can you identify transmitted optical signals when working with fiber optic patch cords?
By observing bright white spots through a smartphone camera
What is the primary locking mechanism used by the Straight Tip (ST) fiber optic connector?
Push and Twist
What is the purpose of using a hot aisle/cold aisle layout in a data center?
To maximize cooling efficiency
For what reason might a company deploy 10/40 GbE Ethernet in its network?
To support very high bandwidth data transfers
Which of the following is a typical use of twinaxial cables?
Data centers intercoms
ou are overseeing the installation of a new fiber optic network in an office building. The network design includes a central switch connected to various endpoints throughout the building using fiber optic cables.
To ensure a successful installation, you need to select the appropriate type of fiber optic patch cords for connecting the endpoints to the switch. The network requires high data transmission quality with minimal back reflection.
Which type of fiber optic patch cord finishing should you choose?
UltraPhysical Contact (UPC) finishing
What are the potential causes of intermittent loss of connectivity in a cabling system? (Select two.)
Excessive untwisted cables end & Attenuation
What is a primary function of a Power Distribution Unit (PDU) in a data center?
To distribute power to multiple devices in a rack
What is the primary purpose of a jam signal in a contention-based MAC system like Ethernet?
To signal that a collision has occurred on the network
What is the MOST significant disadvantage of using copper cabling for networking?
High attenuation over long distances
Users must do their part to maintain network security. How can users know how to reduce risk factors?
Users should be trained in risk mitigation.
How is crosstalk measured in a cabling system?
dB (decibels)
In a high-rise office building, the fire alarm system detects smoke on one of the floors. The building is equipped with a sophisticated fire suppression system that includes automatic smoke detectors, manual alarm points, and a combination of wet-pipe and pre-action sprinkler systems.
The fire is located in a storage room filled with paper products, which is adjacent to the server room.
Given the situation, what immediate action should the building's fire safety team prioritize to effectively manage the fire while minimizing potential damage to the server room?
Use portable Class A fire extinguishers to control the fire in the storage room.
Which of the following is true about the color coding of conductors in a 4-pair data cable according to the T568A and T568B termination standards?
Each pair is assigned a color (Blue, Orange, Green, or Brown).
You are the network administrator for a medium-sized data center that is undergoing an upgrade to improve its network infrastructure. The upgrade includes enhancing the connections between top-of-rack (ToR) switches and servers within the same racks to support 10 GbE speeds. The distance between the switches and servers does not exceed 5 meters.
You need a cabling solution that offers high-speed data transfer, minimal latency, and is cost-effective for the short distances involved.
What type of cable would be MOST appropriate for connecting the ToR switches to the servers within the same racks to meet the 10 GbE speed requirement?
Twinaxial cables with DAC transceivers
How many fiber strands are required for a 40 Gbps link comprising 4 x 10 Gbps lanes using Multi-fiber Push On (MPO) connectors?
What mark is given to plenum-rated data cable under the US National Electrical Code (NEC)?
CMP/MMP
What are the following are requirements for fire-retardant plenum cable?
Must be self-extinguishing
Must not emit large amounts of smoke when burned
A network technician is researching standards for the physical and data link layer.
What standard, developed to implement the functions of the physical and data link layers of the OSI model, is the most important?
802.3
What primarily causes attenuation in a network cable?
Length of the cable
What is the primary purpose of Wavelength Division Multiplexing (WDM)?
To provision multiple channels over one or two strands of fiber
A company is planning to upgrade its data center to support increased data traffic and improve the efficiency of its server interconnections and network backbones.
The IT department has been tasked with selecting the appropriate fiber optic cabling to meet the company's future bandwidth requirements. They are considering the implementation of a 10 Gbps Ethernet over fiber solution to replace their existing network infrastructure.
Given the need for high bandwidth and long-distance transmission capabilities, what type of fiber optic cable and Ethernet standard should the IT department choose?
Single Mode Fiber (SMF) with long wavelength optics for 10 Gbps Ethernet standard
What type of sprinkler system holds water at high pressure and discharges water when triggered by heat?
Wet pipe
