11. Network Management

Front 1

As related to networks, this is a formalized system of tracking network components and managing the lifecycle of those components.

Front 2

A collection of data portraying the characteristics of a network under normal operating conditions. Data collected while troubleshooting can then be contrasted against ________ data.

Baseline

Front 3

When troubleshooting a link where you suspect this condition, you can use a piece of test equipment called _________________which contains both a pattern generator (which can generate a variety of bit patterns) and an error detector (which is synchronized with the pattern generator and can determine the number of bit errors) and can calculate a BER for the tested transmission link.

Front 4

A piece of test equipment typically used by telephone technicians. The clips on a _________can connect to the tip and ring wires on a punch-down block (for example, a 66 block or a 110 block) connecting to a telephone. This allows the technician to check the line (for example, to determine whether a dial tone is present on the line and determine whether a call can be placed from the line).

If you are working with existing cable and want to determine its category, or if you simply want to test the supported frequency range (and therefore data throughput) of the cable, you can use a _____ ______.

Cable certifier

Front 6

A_____ _____can test the conductors in an Ethernet cable. It contains two parts. By connecting these parts of the _____ ______to each end of a cable under test, you can check the wires in the cable for continuity (that is, check to make sure that there are no opens, or breaks, in a conductor). In addition, you can verify an RJ-45 connector’s pinouts (which are wires connected to the appropriate pins on an RJ-45 connector).

To prevent static electricity in your body from damaging electrical components on a circuit board, you can wear an ___ ___ ____. The strap is equipped with a clip that you can attach to something with a ground potential (for example, a large metal desk). While wearing the ____ ____, if you have any static buildup in your body, the static flows to the object with a ground potential to which your strap is clipped, thus avoiding damage to any electrical components that you might touch.

Front 9

Detects the location of a fault in a fiber cable by sending light down the fiber-optic cable and measuring the time required for the light to bounce back from the cable fault. The _____ can then mathematically calculate the location of the fault.

Back 9

Optical time domain reflectometer (OTDR)

Front 10

When terminating wires on a punch-down block (for example, a 110 block), you should use a ______ ______, which is designed to properly insert an insulated wire between two contact blades in a punch-down block, without damaging the blades.

Front 11

A protocol used to monitor and manage network devices, such as routers, switches, and servers.

Simple Network Management Protocol (SNMP)

Front 12

A ______-logging solution consists of two primary components: ______ servers, which receive and store log messages sent from ______clients; and ______ clients, which can be a variety of network devices that send logging information to a _______ server.

Back 12

Syslog

Front 13

Detects the location of a fault in a copper cable by sending an electric signal down the copper cable and measuring the time required for the signal to bounce back from the cable fault. A _____ can then mathematically calculate the location of the fault.

Back 13

Time domain reflectometer (TDR)

Front 14

Sometimes called a fox and hound, a _____ _____ allows you to place a _____ generator at one end of the connection (for example, in someone’s office) and use a ______ on the punch-down block to audibly detect to which pair of wires the ______ generator is connected.
