1
Refer to the exhibit. This switch is to be added to the production network. Which two facts about VLANs and VTP operation can be confirmed by this output? (Choose two.)
The network administrator will be able to configure VLANs of local significance on this switch.
VLANs can only be added to the VLAN database on this switch by a VTP advertisement.
All VLANs that are configured on this switch will be sent to all other switches in the same VTP domain.
This switch will drop all VTP advertisements that come from switches that are configured in the same VTP domain.
Adding this switch to the network will cause no disruption in the VTP domain operations if the rest of the switches in the same VTP domain have a higher configuration revision number.
2 Which statement correctly describes the spanning-tree path cost?
It is calculated based on the total number of switches connected in a loop.
It is calculated based on the utilization of all the switches along a given path.
It is calculated based on the bridge priority of the switches along a given path.
It is calculated based on the sum of the port cost value, determined by link speed, for each switch port along a given path.

3 Which method establishes an administrative connection for configuring the Linksys WRT300N wireless access point?
Associate with the access point and then open a HyperTerminal session with the access point.
Physically connect to the access point and then reboot the computer to launch the configuration software.
From a computer in the same IP subnet as the access point, enter the default IP address of the access point in a web browser.
Modify the TCP/IP properties of the computer connected to the access point so that it exists on the same network, and then reboot your computer to establish a connection.

4
Refer to the exhibit. Hosts PC_A and PC_B send traffic simultaneously, and the frames from the transmitting stations collide. What is the last device to receive the collision?

hub HB1
switch SW1
router R1

router R2
switch SW4
5
Refer to the exhibit. A network administrator is configuring RT1 for inter-VLAN routing. The switch is configured correctly and is functional. Host1, Host2, and Host3 cannot communicate with each other. Based on the router configuration, what is causing the problem?

Interface Fa0/0 is missing IP address configuration information.
IP addresses on the subinterfaces are incorrectly matched to the VLANs.
Each subinterface of Fa0/0 needs separate no shutdown commands.
Routers do not support 892.1Q encapsulation on subinterfaces.
6
Refer to the exhibit. Switch SW2 has been newly purchased and added to the network. What configuration should be applied to SW2 so that it participates in the same VTP domain as switch SW1, receives VLAN information from SW1, and synchronizes VLAN information?

Disable VTP pruning on SW2.

8 Which statement correctly describes a function of a Layer 2 switch?

It routes packets between different LAN segments.
It uses the destination MAC address to selectively forward a frame.
It performs switching and filtering based on the destination network layer address.
It drops a frame whose destination MAC address is not in the MAC address table.

9 What is the purpose of the Spanning Tree algorithm?

It propagates VLAN configurations to other switches.
It restricts broadcast packets to a single VLAN.
It segments a network into multiple broadcast domains.
It prevents loops in a switched network with redundant paths.

10

It will be forwarded out ports Fa0/5 and Fa0/10.
It will be forwarded out ports Fa0/5, Fa0/10, and Fa0/15.

11


Refer to the exhibit. If switch SW1 is configured with the four VLANs as shown in the exhibit, how many physical interfaces are needed on router R1 to configure inter-VLAN routing using subinterfaces?

zero
one
two
four


12


Refer to the exhibit. Which three options correctly identify information that could be associated with this output?(Choose three.)

Interface FastEthernet3/0/0 is subinterfaced.
A non-proprietary trunking protocol is in use.
The configuration is appropriate for a router-on-a-stick network design.
A shutdown command has been applied to interface FastEthernet3/0/0.
Interface FastEthernet3/0/0.3 is mapped to the default management VLAN.
An IP address should be applied to FastEthernet3/0/0 for correct data routing.


13


Refer to the exhibit. Computer D sends a broadcast message. Which devices will process the broadcast message?

computer E
computer D and computer E
computer D, computer E, and Router1
computer B and computer E
computer B, computer E, and Router1
computer C, computer D, and computer E
computer C, computer D, computer E, and Router1
computer A, computer B, computer C, computer D, computer E, and Router1


14


Refer to the exhibit. What would happen if the network administrator moved the network cable of Host A from interface Fa0/1 to Fa0/3 on switch SW1?

Host A remains a member of VLAN 10, because the router is routing traffic between VLANs.
Host A is no longer a member of VLAN 10, because port Fa0/3 has been manually assigned to VLAN 30.
Host A remains a member of VLAN 10, because the switch provides dynamic VLAN assignment for the port.
Host A maintains connectivity to all members of VLAN 10, because it is connected to the same physical network.
Host A is no longer a member of VLAN 10, but because port Fa0/3 was unused, it is now a member of VLAN 1

15


Refer to the exhibit. What does STATIC indicate in the output that is shown?

Switch port Fa0/24 can only work in VLAN 99.
VLAN 99 was manually added to the VLAN database.
MAC address 0001.637b.b267 was learned from the source address of a frame that was received on switch port Fa0/24.
MAC address 0001.637b.b267 was manually associated with the switch port Fa0/24.
