Cisco - CCNA Routing and Switching
Essentials Exam 1/Questions and
Answers (Study cards for chapter one's
exam.)
What is one advantage of using the cut-through switching method instead of
the store-and-forward switching method? - -Has a lower latency appropriate
for high-performance computing applications.
-A _______ network is one that uses the same infrastructure to carry voice,
data, and video signals. - -Converged.
-[Refer to the exhibit] How is a frame sent from PCA forwarded to PCC if the
MAC address table on switch SW1 is empty? - -SW1 floods the frame on all
ports on SW1, excluding the port through which the frame entered the
switch.
-[Refer to the exhibit] Consider that the main power has just been restored.
PC1 asks the DHCP server for IPv4 addressing. The DHCP server sends it an
IPv4 address. While PC2 is still booting up, PC3 issues a broadcast IPv4 DHCP
request. To which port will SW1 forward this request? - -To Fa0/1, Fa0/2, and
Fa0/3 only. [This graphic changes but the principle is the same, whatever
line PC3 is on is the line (port) that will not receive the broadcast.]
-[Refer to teh Exhibit] There are ______ collision domains in the topology. - -
12
-What does the term "port density" represent for an Ethernet switch? - -The
number of available ports.
-An administrator purchases new Cisco switches that have a feature called
StackPower. What is the purpose of this feature? - -It enables the sharing of
power among multiple stackable switches.
-What is a collapsed core in a network design? - -A combination of the
functionality of the distribution and core layer.
-What is one function of a Layer 2 switch? - -Determines which interface is
used to forward a frame based on the destination MAC address.
-What is a basic function of the Cisco Borderless Architecture ACCESS layer?
- -Provides access to the user.
