Jason Dion Network Plus

Used to reduce redundancy or increase throughput, directly affecting a wireless connection's speed. Signal strength only refers to the maximum transmitted power by an antenna

a useful tool, helping you do things like track traffic and malicious usage on the network i.e. Wireshark

sends unsolicited messages over bluetooth to bluetooth enabled devices such as mobile phones, PDAs, or laptop computers

Allows network segments and broadcast domains to communicate with each other. Allows two broadcast domains for each side of the router

ST, SC, LC, LC, FC

Switch to a switch Workstation to workstation

Computer to switch Router to modem

Shorter distances than single-mode fiber Larger core size allows for multiple modes of travel for the light signal

Coordinated system to account for upgrades, installs, and network outages Should include the specific details of what was changed and what things may have been affected by the change

Important for a company's long-term health in the event of a disaster

Is a self-contained computer that connects to a home business network and can share files over TCP/IP Consists of a hard disk for storage of files and usually utilizes a RAID system for redundancy and/or performance

Specialized LAN designed for data transfer/storage Transfers data at block level with special protocol

Removes need for specialized software Runs over your Ethernet

Lower cost, built using Ethernet switches (<10 Gbps) Relies on configuration allowing jumbo frames over the network

Layer 2 The switch is DHCP firewall Trusted: routers, switches, DHCP servers Untrusted: Other computers, unofficial DHCP servers

Where devices go that do not meet the regular network's standards can be placed. They can be checked in this area before connecting

allow the cabling to be placed under the floor, but still accessible to the network administrators (Hides the cabling)

enables the network administrator to view device error information from a central location All network infrastructure devices send system-level information to a centralized server

Man-in-the-middle attack on a wireless network May be used to steal the passwords of unsuspecting users by monitoring their connections or phishing, which involves setting up a fraudulent website

canonical name records can be used to alias one name to another i.e. google.com & www.google.com

There is more than one layer 2 path between two endpoints i.e. Two switches connected using both a Cat 6 and a Cat 5e It can be prevented with Spanning Tree Protocol (STP)

Allows a new piece of hardware to be installed and the configuration from the previous device can be restored

5Ghz MIMO provides support for dozens of non-overlapping channels

Steps a technician uses to solve a problem: identify the problem, establish a theory of probable cause, test the theory, establish and implement a plan of action, verify functionality, and document findings.

A method of remapping one IP address space into another by modifying network address information in the IP header packet

is a type of server that provides a suite of services to connect users to a network or the internet remotely. Will usually be an RDP or VNC

A piece of equipment that connects a T-carrier leased line from the telephone company to a customer's equipment (such as a router). It performs line encoding and conditioning functions, and it often has a loopback function for testing.

A third-party computer that passes traffic to and from a specific address without revealing the address of the connected user. Can come up as an unexpected source IP address

Install and configure a virtual switch

A device for making, breaking, or changing the connections in an electrical circuit.

A software-based switch that provides functionality similar to physical switches, and is used for connecting virtual systems to form a network.

Used to control the combining of ports. Can increase bandwidth and throughput. Can provide network redundancy and load balancing

Conduct real-time monitoring of the phone's activity and usage

Has the capability to capture the TCP handshake and display it for analysis

Firewall connects directly to the router, and the router connects directly to the computer. This would form a single line

Used to manage credentials centrally, combines authentication and authorization

Used for securing key exchanges during client-to-server VPN connection. Used in IPsec, which is commonly used in securing the key exchange during the establishment of a client-to server VPN connection

relies on virtual circuits and point-to-multipoint connections. specifies the physical and data link layers of digital telecommunication channels using a packet switching methodology

Can provide a pass or fail status following the industry standards - can show info such as open and short or the length

record requires in the DNS for a domain for the email server to accept emails - would allow the new server to receive email on behalf of diontraining.com

allows for two or more signals or bitstreams to be transferred in what appears to be simultaneous sub channels in one communication channel Delivers multiple calls over a copper wire if you have an ISDN or T1-connection

used for managing all entities on a network using SNMP protocol

Used to access the device during a one-time check-in at login Used to perform a one time temporary posture

a router/switch console port is connected using this

collision domain

collision domain

cables can be easily removed or added cost-effective and allow for easy installation

a method to prevent a router from sending packets through a route that has become invalid within computer networks Prevents routing loops

Layer 3

10GB Ethernet LAN standard over MMF

A fiber connection most common used in fiber and LAN networking applications

a wireless network that can utilize multiple WAPs to a broadcast network

in a SAN

Security through isolation

Straight-through cable

crossover cable

Straight-through cable

crossover cable

Deep pack inspection to identify which applications or protocol is actually being used to send traffic over a given port
