Switching, Routing, and Wireless Essentials Practice Final
Exam 2023 Questions and Answers
A network administrator is using the router-on-a-stick method to configure inter-VLAN
routing. Switch port Gi1/1 is used to connect to the router. Which command should be
entered to prepare this port for the task?
Switch(config)# interface gigabitethernet 1/1
Switch(config-if)# switchport mode trunk
Refer to the exhibit. The configuration shows commands entered by a network
administrator for inter-VLAN routing. However, host H1 cannot communicate with H2.
Which part of the inter-VLAN configuration causes the problem?
VLAN configuration
Refer to the exhibit. Inter-VLAN communication between VLAN 10, VLAN 20, and VLAN
30 is not successful. What is the problem?
The switch interface FastEthernet0/1 is configured as an access interface and should
be configured as a trunk interface.
An employee connects wirelessly to the company network using a cell phone. The
employee then configures the cell phone to act as a wireless access point that will allow
new employees to connect to the company network. Which type of security threat best
describes this situation?
rogue access point
Which combination of WLAN authentication and encryption is recommended as a best
practice for home users?
WPA2 and AES
What are the two methods that a wireless NIC can use to discover an AP? (Choose
two.)
transmitting a probe request
receiving a broadcast beacon frame
What address and prefix length is used when configuring an IPv6 default static route?
::/0
Refer to the exhibit. Match the description with the routing table entries. (Not all options
are used.)

Match the dynamic routing protocol component to the characteristic. (Not all options are
used.)
Data Structures- tables or databases that are stored in RAM
Routing protocol messages- exchanges routing information and maintains accurate
information about networks
Algorithm- a finite list of steps used to determine the best path
Which statement describes the behavior of a switch when the MAC address table is
full?
It treats frames as unknown unicast and floods all incoming frames to all ports within the
local VLAN.
Which term describes the role of a Cisco switch in the 802.1X port-based access
control?
authenticator
What is a result of connecting two or more switches together?
The size of the broadcast domain is increased.
A small publishing company has a network design such that when a broadcast is sent
on the LAN, 200 devices receive the transmitted broadcast. How can the network
administrator reduce the number of devices that receive broadcast traffic?
Segment the LAN into smaller LANs and route between them.
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.
