WGU C172 NETWORK AND SECURITY
FOUNDATIONS CERTIFICATION EVALUATION
◉ What is OSI meant for? Answer: To provide a framework for
networking devices that ensure compatibility in the network
hardware and software.
◉ What is the OSI model meant to accelerate? Answer: The
development of new networking technologies.
◉ What is layer 1 of the OSI model? Answer: Physical
◉ The layer of the OSI model that provides the electrical and
mechanical connection to the network. Answer: physical
◉ UTP, fiber, and network interface cards are examples of which
layer of the OSI model? Answer: physicaL
◉ What is layer 2 of the OSI model? Answer: Data link
,◉ Layer of the OSI model that handles error recovery, flow control
(synchronization), and sequencing (which terminals are sending and
which are receiving) Answer: data link
◉ Also called the media access control layer Answer: data Link
◉ The layer of the OSI model where the Media Access Control or
MAC, addressing is defined Answer: data lInk
◉ Where is the Ethernet 802.3 standard defined? Answer: In the
MAC or media access control
◉ Also called the Ethernet address Answer: MAC or media access
control
◉ MAC addresses are an example of which layer of the OSI model?
Answer: data linK
◉ What is layer 3 of the OSI model? Answer: Network
◉ layer of the OSI model that accepts outgoing messages and
combines messages or segments into packets, adding a header that
includes routing information. Answer: network
, ◉ Acts as the network controller Answer: network layer of the OSI
model
◉ Internet Protocol (IP) and internetwork packet exchange (IPX) are
examples of which layer of the OSI model? Answer: networK
◉ What is layer 4 of the OSI model? Answer: Transport
◉ layer of the OSI model that is concerned with message integrity
between source and destination Answer: transport
◉ layer of the osi model that also segments/reassembles the packes
and handles flow control Answer: tRansport
◉ Transmission control protocol (TCP) and User Datagram Protocol
are examples of which layer of the OSI model? Answer: transporT
◉ What is layer 5 of the osi model? Answer: Session
◉ layer of the osi model that provides the control functions
necessary to establish, manage, and terminate the connections as
required to satisfy the user request Answer: session
