Network Management Flashcards
Shows the actual physical arrangement of the components that make up the network
Physical Network Diagram
illustrates the flow of data across a network and shows how devices communicate with each other
Logical Network Diagram
Labels which cables are connected to which ports
Wiring Diagram
Planning and designing a wireless network to deliver the required wireless Solution
Wireless Site Survey
Determines if a site has the right amount of power, space and cooling support a new upgrade or install
Wired Site Survey
Delivered after a formal assessment has been conducted

Audit and Assessment Report
Set of Specifications for an information system, or a configuration item within a system, that has been formally reviewed and agreed on
Baseline Configurations
Monitors the performance the end user’s workstation to the final destination they are trying to reach
Network Performance Monitoring
Time it takes for data to reach its destination across a network
Latency
maximum rate of data transfer across a network
Bandwidth
actual measure of how much data is successfully transferred from the source to a destination
Throughput
When a time delay in the sending of data packets over a network connection occurs
ex: on a video, if someone is speaking and it goes silent, and they start to speak but they are speaking faster
Jitter
What can be implemented to prevent jitter
QoS
Monitors a device’s temperature, CPU usage, and memory, which could indicate if it is operating properly or is about to fail
Sensor
Used to set off an alarm when temperature reaches dangerous conditions
Major Temperature Threshold
Captures the entire packet, including the header and the payload for all traffic entering and leaving a network
Full Packet Capture
Relies on a flow collector to record metadata and statistics about network traffic rather than recording each frame
Flow Analysis
Defines a particular traffic flow based on the different packets that share the same characteristics
NetFlow
Passively monitors a network like a sniffer, but only logs full packet capture data of potential interest
Zeek
Creates graphs showing traffic flows through the network interfaces of routers and switches by polling the appliances using SNMP
Multi Router Traffic Grapher (MRTG)
communicates whether a given interface has a cable connected to it and a valid protocol to use for communication
Link State
Used to count the number of packets that have been dropped
Drop
Used to count Selective Packet Discards (SPD) that have occurred
Flush
Drops low priority packets when the CPU is too busy so it can save capacity for higher priority packets as a form of QoS
Selective Packet Discards (SPD)
An Ethernet frame that is less than 64 bytes in size
Runt
Any Ethernet frame that exceeds the 802.3 frame size of 1518 bytes
Giant
Number of packets received that failed the cyclic redundancy checksum, or CRC check upon receipt
CRC
Used to count the number of packets where are CRC error and non-integer number of octets was received
Frame
Used to count how often the interface was unable to receive traffic due to an insufficient hardware buffer
Overrun
Used to count the number of packets that the interface ignored since the hardware interface was low and internal buffers
Ignored
Used to count any frames that are transmitted and are larger than 1518 bytes
Babble
Used to count the number of frames that were transmitted successfully after waiting because the media was busy
Deferred
Number of times a packet was not output from the output hold queue because of a shortage of shared memory
Output Buffer Failure
