OBJ 5 Flashcards
OBJ 5.2
Cyclic Redundancy Check (CRC)
Error in data Transmission
OBJ 5.4
Throughput capacity
Maximum rate at which data can be transferred
OBJ 5.4
Bandwidth allocation
how network bandwidth is distributed across devices, services, or applications. The goal is to prioritize critical traffic and prevent congestion.
OBJ 5.4
ICMP
Sending control and error messages between devices
Many companies block imcp. Which causes ping to fail.
OBJ 5,5
Giants
Giants are frames larger than the maximum Ethernet frame size (1518 bytes)
Can be caused by network congestion, misconfigured devices, or errors in frame processing
OBJ 5,5
Runts
frames smaller than the minimum Ethernet frame size
OBJ 5,5
CRC errors
Occur when the cyclic redundancy check fails
OBJ 5,5
Drops
Occur when the switch’s buffer is full and cannot process incoming frames
OBJ 5,5
Traffic Access Point (TAP)
Silently intercepting network traffic without disrupting operations. More seamless than network Sniffer.
OBJ 5,5
Nslookup
Query the dns to obtain info about host address, mail exchanges and name servers
OBJ 5,5
Packet Capture
Contain every packet that is sent and received by the network
OBJ 5,5
-sU in Nmap
Identify open UDP ports on a target device
OBJ 5,5
Nmap
Scan the network for devices and provide information, including open ports and running services
OBJ 5,5
LLDP (Link Layer Discovery Protocol) and CDP (Cisco Discovery Protocol)
Provide information about directly connected devices
OBJ 5,5
Show config
shows device’s current configuration
OBJ 5,5
Show interface
display statistics for a given network interface
OBJ 5,5
Show route
display current state of the routing table
OBJ 5,5
Show diagnostic
display hardware and software on each node in a networked device
