WGU D481 Security Foundations – Accurate
Solutions To All Your Questions
Desktop computers are connected to the building backbone in the
wiring closet. What is another name for this wiring closet? Right
Ans - Intermediate distribution frame (IDF)
802.3-1983 Right Ans - 10Base5
802.3a-1985 Right Ans - 10Base2
802.3i-1990 Right Ans - 10Base-T
802.3j-1993 Right Ans - 10Base-F
802.3af-2003 Right Ans - PoE
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? Right Ans - 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? Right Ans - 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? Right Ans -
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? Right Ans -
Running servers with dual Network Interface Cards (NIC) can
provide resiliency.
Connection-oriented Right Ans - Normal discussion between two
people
User Datagram Protocol (UDP) Right Ans - Connectionless
Transmission Control Protocol (TCP) Right Ans - Connection-
oriented
