Cisco CCNA Routing and
Switching Essentials
Exam 1
What is one advantage of using the cut-through switching method instead of the store-and-
forward switching method? - ANSWERSHas 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. - ANSWERSConverged.
[Refer to the exhibit] How is a frame sent from PCA forwarded to PCC if the MAC address table
on switch SW1 is empty? - ANSWERSSW1 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? -
ANSWERSTo 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. - ANSWERS12
What does the term "port density" represent for an Ethernet switch? - ANSWERSThe number of
available ports.
An administrator purchases new Cisco switches that have a feature called StackPower. What is
the purpose of this feature? - ANSWERSIt enables the sharing of power among multiple
stackable switches.
