Desktop computers are connected to the building backbone in the wiring closet. What is another
name for this wiring closet? - Answer✔Intermediate distribution frame (IDF)
802.3-1983 - Answer✔10Base5
802.3a-1985 - Answer✔10Base2
802.3i-1990 - Answer✔10Base-T
802.3j-1993 - Answer✔10Base-F

Most modern networks follow the 802.3 standard. This standard offers technical solutions to
business needs. One business need is to connect client workstations to servers. Which technical
solution does 802.3 offer for this business? - Answer✔Create a star-wired network using
switches
Ethernet started with a bus topology. Computers in Ethernet use shared media and therefore need
an access control system to allow them to share this media. Which system does Ethernet use for
access control of shared media? - Answer✔Carrier Sense Multiple Access Collision Detection
(CSMA/CD)
Legacy networks contained hubs and bridges. Most modern networks use switches and routers
but not hubs and bridges. Why have bridges been removed from modern networks? -
Answer✔Bridges were phased out because they are not needed to divide collision domains in
modern networks; switches perform this task.
Computer networks provide critical functions for organizations. This means that network
resiliency is very important. How can a network architect build resiliency into a network? -
Answer✔Running servers with dual Network Interface Cards (NIC) can provide resiliency.
Connection-oriented - Answer✔Normal discussion between two people
User Datagram Protocol (UDP) - Answer✔Connectionless
Transmission Control Protocol (TCP) - Answer✔Connection-oriented
Internet Protocol (IP) - Answer✔Connectionless

network backbone? - Answer✔Dual NICs
Which 6-byte or 48-bit address is defined in the 802 standard? - Answer✔MAC address
What are the layers of the TCP/IP Reference Model? - Answer✔Application, Transport, Internet,
and Network Access Layers
