Networking Exam #1 Questions with Correct Answers
OSI Model and Devices - ✔✔Physical: UTP STP cables, fiber optic, cat, hubs, etc.
Datalink: NICs and switches
Network: Routers
Transport: TCP/UDP
Session: SMB SIP (voice)
Presentation: TSL, SSL
Application: HTTP
ICMP - ✔✔Internet Control Message Protocol. Used for network error messages
and diagnostics. Used to report problems and diagnostics. Ping, traceroute.
unicast - ✔✔one sender to one specific receiver
multicast - ✔✔one sender to a selected group of receivers

nearest/best one.
Cat 5-8 vs Fiber max distance - ✔✔Cat 5, 100m
Cat 5e, 100m
Cat 6, 100m for 1Gbps, 55m for 10Gbps
Cat 6a, 100m
Cat 7, 100m
, Cat 8, 100ft

Link-local address - ✔✔An IP address that only works on the local network
segment and is not routed across the internet or other networks.

announce it's presence to other devices, makes network setup easier
QoS (Quality of Service) (networks) - ✔✔Allows certain devices preference for
bandwidth over others
