QUESTIONS WITH VERIFIED
ANSWERS/2023-2024/GRADED
A+/ 100% ACCURATE
Network Topology - -The Physical/Logical shape of a network
-Logical Topology - -Gives the description for the physical layout, shows
VLAN's and where they are placed on the physical topology
-Trunk Port - -Connects packets that travel to all VLAN's on a switch
-Baseband Systems - -Transmits one signal on the medium (fiber,
copper, etc)
-Broadband - -Form of multiplexing to join multiple signals on a medium
-Ethernet - -Designed as baseband system that can be used in
multiplexing
-CSMA/CD - -Carrier Sense Multiple Access/ Collision Detection
-Unicast - -Broadcast for a single device
-Multicast - -Broadcast for a specific group or multiple devices
-Broadcast - -Message for everyone to receive and process
-Hub - -Broadcasts packets to every single port
-Switch - -Broadcasts packets to device found on a singular port
-Content Addressable Memory (CAM) - -Is a table that contains the MAC
address and port associated to that MAC Address
-Virtual LAN (VLAN) - -Splitting a switch in which certain ports can only
talk to certain ports (Segment networks within a switch)
-Multiprotocol Label Switching (MPLS) - -A different way of switching
packets that can be used on a dedicated line
-802.1x - -Network Access Control that is a layer 2 authentication
(Credentialed Question of 2FA)
, -A security appliance should be set in place when - -There is a change
in trust level in the network
-Protocol - -is an agreement or rules of engagement for how computer
networks communicate
-OSI Protocol Stack (7) - -Layer 7) Application
Layer 6) Presentation
Layer 5) Session
Layer 4) Transport
Layer 3) Network
Layer 2) Data Link
Layer 1) Physical
-Application Layer 7 OSI Stack - -Browsers, FTP, HTTP, SCP
-Presentation Layer 6 OSI Stack - -Makes data presentable to the
application or user (ASCII)
-Session Layer 5 OSI Stack - -Handles the establishment/maintenance
of connections between systems
-Transport Layer 4 OSI Stack - -Determines that application the packet
should be sent to through port numbers (Web on 80,443)
-Network Layer 3 OSI Stack - -Moving packets from one network to
another network, uses logical addressing instead of physical addressing
-Data Link Layer 2 OSI Stack - -Takes a packet and frames it suitable for
transmission
-Physical Layer 1 OSI Stack - -Network cable, electromagnetic radiation
-TCP/IP Protocol Stack (4) - -Layer 4) Application
Layer 3) Transport (TCP/UDP)
Layer 2) Internet (IP)
Layer 1) Network
-Network Address in: 10.1.2.0/24 Subnet - -10.1.2.0
-Broadcast Address in: 10.1.2.0/24 Subnet - -10.1.2.255
-Class A CIDR Addressing (Mask, IP Range) - -N.H.H.H, 255.0.0.0 - 1-127
10.0.0.0/8
16.7 Million IP's
-Class B CIDR Addressing (Mask, IP Range) - -N.N.H.H, 255.255.0.0 -
128-191
172.16.0.0/16
