Network + Chapter 4 – Flashcards

The portion of an ethernet network in which collisions could occur if two nodes transmit data at the same time

In a chassis, the path along which air from a cool air source is conducted, pass equipment to cool it, and then out of the rack. Typically, air moves from front to back

They specialized storage device or group of storage devices that provide centralized fault tolerant data storage for network

The industry standard unit for measuring rack height. Stack racks are 42 U tall to about 6 feet

The field in which a Frame responsible for ensuring that data carried by the frame arise intact. It uses an algorithm, such as CRC, to accomplish this a verification

A device that converts DC electrical energy to AC electrical energy. Better inverts will also condition the device power, which helps protect sensitive electronic equipment from power fluctuations

How far away from fluorescent lights or some other sources of EMI should cable be installed

In order to simplify consul access to computer and a rack, what device is typically used to provide essential portal for all devices on the rack

If the use of a pre-existing infrastructure is desired for a S AN, wet transport layer protocol should be utilized

Which of the following options is not a likely source of electromagnetic interference

Which method of transmission allow signal to travel in both directions over a medium simultaneously

What is the maximum frame size for ethernet two frames on a VL AN

What is the maximum allowable distance for horizontal wiring

What cable type comes into different notes, single mode and multiple modes

Which method of transmission allow signal to travel in both directions over medium but in only One Direction time

The radius of the maximum arc into which you can Lupe cable without impairing data transmission is known as what option below

Select the component of enterprise level structured cabling that serves as a location where an incoming network interface and use a building and connect with the buildings backbone cabling

Deering termination of twisted-pair cabling what should be done to ensure minimal crosstalk is introduced

What Component of the backbone runs between a building floors and give you to connect and MDF and IDF are multiple IDF

Where is the D Mark located in relation to the structured cabling of enterprise environment

What type of power converter change the voltage of an AC current, such as one power over the mainline for the electric company is changed for being delivered to a home

Ethernet exist at what layer of the OSI model

When selecting a punch down block wall block time is more suitable for data connections

One watt is equal to how many volts amps

What is the industry standard for a rack in rack units

What type of power flow involves a fluctuation of voltage levels caused by other devices on the network or by EMI

Selected to transport layer protocols that are used by the SANz

Slut the maximum allowed with distances for horizontal wiring for his span that connects the data jack on a walk to like data closet, and for span that connects the workstation to the data Jack respectively

Equipment racks most commonly come and what two widths

Selected to terms below that I used to describe a UPS that provides continuous voltage to a device by switching virtually instantaneously to the battery when it detects a loss of power

The standard that you describe the uniform, enterprisewide cabling systems, regardless of who manufactures or sells the various parts use the system, can be referred to by what two options below

Explain the difference between an inverter and a rectifier

Describe the three different types of cabling recognized by TIA/EIA acceptable for horizontal wiring

What steps should be taken to manage documentation at a cabling plant

Explain how equipment should be configured in a rack to best optimize airflow in temperature

Describe the differences between a brown out in the blackout

A power fluctuation that result in a temporary dimming of light is known as a blackout

Cable that is coated with frame resistant polyvinylchloride is acceptable for use plenty of areas

The TIA/EIA standard for wall jacks in the world areas required that at least one outlet be provided for data and one for voice

Each type of cable has prescribed bend radius, which is the radius of the Maxim arc into which you can Lupe cable without impairing data transmission

Hey NIC card cannot determine whether the frames it transmits and receives are using IP packets or a different layer 3 protocol, because the NIC does not operate higher than level two of the OSI model
