An ephemeral port is a short-lived transport protocol port for
What is an ephemeral port? Internet Protocol (IP) communications. Can be used by both TCP
& UDP.

Name five network types. LAN, WAN, MAN, VLAN, WLAN, PAN.
Name five network topologies Mesh, Ring, star, Tree, Bus.
Name five common ethernet 100Base5, 10Base2, 10BaseT, 100Base-FL, 1000Base-T.
and FDDI cable types.
What is WIFI the alias for? IEEE 802.11
What does VLAN stand for? Virtual Local Area Network
Virtual Local Area Networks (VLANs) separate an existing
physical network into multiple logical networks.
How does VLAN work? Thus, each VLAN creates its own broadcast domain.
Communication between two VLANs can only occur through a
router that is connected to both.

What does ICMP stand for? Internet Control Message Protocol
What does TTL stand for? Time to Live
TTL is a hop count system, and each router decreases the TTL by
1. Upon reaching 0, the packet is dropped. This way you don't

have packets not reaching their destination and clogging the
network.
OS TLL numbers? 128 Windows, 64 linux, 255 solaris(kapp)
Traceroute is when you send a packet with a TTL value of 1 once
it reaches the first router it will die sending a ICMP message to
sender, at which point the sender can send another one with a
What is Traceroute
value of 2 to see how far it will go. By doing this we can see how
many hops it will take to reach our target. (A good way of
enumeration of a network, when in a black box pen-test.)
Ping sweep is just a technique that can be used to find out which
What is ping sweep?
hosts are alive in a network or large number of IP addresses.
