CMPE 150 FINAL Exam questions and answers with
complete solutions verified graded a++ 2025/2026
Medium Access Control False - required in broadcast networks
is required in all types
of networks
In virtual circuit False - only in datagram networks
networks, packets must
be self-contained and
independent of one
another
In datagram networks, a False - connection only needs to be established in VC
virtual connection networks
between the source
and the destination
must be established prior
to data exchange

Medium Access Control False - collisions can still occur, CSMA just
protocols that use means connection is "carrier-sensing" and
CSMA are collision-free detects whether network is idle or not
Medium-Access True - if everything is working optimally and as
Control protocols it should, there should be no collisions
based on token-
passing, are collision-
free
CSMA-CD based False - collisions can still occur, but CSMA-CD
medium access can detect collisions as they are occurring
control protocols are unlike CSMA
collision-free
Congestion Control is False - it's the other way around
about making sure the
receiver can keep up
with the sender,
whereas flow control
is not about
overwhelming the
network
Going from top to False - it is the network layer first
bottom of the protocol
stack, the transport
layer is the first layer
that is executed by all
nodes in the network
A virtual circuit network False - it aims to provide the same service as
layer atop packet circuit switching networks (establishing a
switching networks connection, allocating resources for a
aims at providing the guaranteed reliable connection)
same service to the
transport layer as
packet switching
networks
Random Access True - however channel partitioning and "taking turns"
