Network Topology - ANSWERSThe Physical/Logical shape of a network
Logical Topology - ANSWERSGives the description for the physical layout, shows
VLAN's and where they are placed on the physical topology
Trunk Port - ANSWERSConnects packets that travel to all VLAN's on a switch
Baseband Systems - ANSWERSTransmits one signal on the medium (fiber, copper,
etc)
Broadband - ANSWERSForm of multiplexing to join multiple signals on a medium
Ethernet - ANSWERSDesigned as baseband system that can be used in multiplexing
CSMA/CD - ANSWERSCarrier Sense Multiple Access/ Collision Detection
Unicast - ANSWERSBroadcast for a single device
Multicast - ANSWERSBroadcast for a specific group or multiple devices
Broadcast - ANSWERSMessage for everyone to receive and process
Hub - ANSWERSBroadcasts packets to every single port
Switch - ANSWERSBroadcasts packets to device found on a singular port
Content Addressable Memory (CAM) - ANSWERSIs a table that contains the MAC
address and port associated to that MAC Address
Virtual LAN (VLAN) - ANSWERSSplitting a switch in which certain ports can only talk to
certain ports (Segment networks within a switch)
Multiprotocol Label Switching (MPLS) - ANSWERSA different way of switching packets
that can be used on a dedicated line
802.1x - ANSWERSNetwork Access Control that is a layer 2 authentication
(Credentialed Question of 2FA)
A security appliance should be set in place when - ANSWERSThere is a change in trust
level in the network
, Protocol - ANSWERSis an agreement or rules of engagement for how computer
networks communicate
OSI Protocol Stack (7) - ANSWERSLayer 7) Application
Layer 6) Presentation

connections between systems
Transport Layer 4 OSI Stack - ANSWERSDetermines that application the packet should
be sent to through port numbers (Web on 80,443)
Network Layer 3 OSI Stack - ANSWERSMoving packets from one network to another
network, uses logical addressing instead of physical addressing
