FCS, DATA, ACK, Sequence,source port, destination port, source ip address, destination ip address, source mac, and destination mac
What is a protocol data unit (PDU)
a group of information added or removed by a layer of the OSI model
Name all of the parts of a Ip packet
Data, ACK, sequence, source port, destination port, source ip address, destination ip address

What does the command trace route do
Shows the amount of hops from your computer to another computer
What does path ping do
pings all of the routers on its way to a destination
What does the Network Time Protocol (NTP) do
allows the synchronization of system clocks (from desktops to servers).
What does Simple Network Time Protocol (SNTP) do
simplified version of Network Time Protocol only when used when the full ntp isnt needed
What port does NTP/SNTP use
port 123
How does NTP operate
In a hierarchical fashion (clock strata)
What protocol does NTP/SNTP use to allow devices to synchronize their clocks
UDP
What is IPAM (IP Address Management)
Keeps track of ip addresses and handles scopes of ip addresses
When should you use MAC reservations
When you have devices that have top priority for address assignment
What protocol does DNS use and what port is it on
UDP and port 53
