Take Assessment - Module 9 Exam - CCNA 3 Switching Basics and Intermediate Routing (Version 3.1)
1 A router has two serial interfaces and two FastEthernet interfaces. It needs to connect to a wide area link to the main office and to four VLANs in the local network. How can this be accomplished in the most efficient manner?
• Connect a trunked uplink from the switch to a router FastEthernet interface and create logical subinterfaces for each VLAN.
• Use a hub to connect the four VLANS with a FastEthernet interface on the router.
• Two additional FastEthernet interfaces are required to interconnect the VLANs.
• Use serial to FastEthernet transceivers to connect two of the VLANs to the router. Attach the other two VLANs directly to the available FastEthernet ports.
• Add a second router to handle the inter-VLAN traffic.

The switches in the diagram are connected with trunks within the same VTP management domain. Each switch is labeled with its VTP mode. A new VLAN is added to Switch3. This VLAN does not show up on the other switches. What is the reason for this?
• VLANs cannot be created on transparent mode switches.
• Server mode switches neither listen to nor forward VTP messages from transparent mode switches.
• VLANs created on transparent mode switches are not included in VTP advertisements.
• There are no ports assigned to the new VLAN on the other switches.
• Transparent mode switches do not forward VTP advertisements.
3
Refer to the graphic. What are some advantages of replacing the individual VLAN links between Switch1 and Switch2 with a single trunk line? (Choose three.)
• It would free 2 switch ports on each switch.
• It would free 3 switch ports on each switch.
• It would save 2 cabling runs.
• It would save 3 cabling runs.
• It would provide three times the bandwidth of the individual links.
• It would allow adding more VLANs without requiring more cabling or switch ports.
4
A switch is configured with the commands shown in the diagram. Host1 is connected to port 0/4 with an IP address of 192.168.1.22/28. Host2 is connected to port 0/5 with an IP address of 192.168.1.33/28. Host3 is connected to port 0/6 with an IP address of 192.168.1.30/28. Select the statements that describe the success of pinging from one host to another. (Choose three.)
• Host1 can ping Host2.
• Host1 cannot ping Host2.
• Host1 can ping Host3.
• Host1 cannot ping Host3.
• Host2 can ping Host3.
• Host2 cannot ping Host3.
5
A router is configured to connect to a trunked uplink as shown in the graphic. A packet is received on the FastEthernet 0/1 physical interface from VLAN 10. The packet destination address is 192.168.1.120. What will the router do with this packet?
• The router will forward the packet out interface FastEthernet 0/1.1 tagged for VLAN 10.
• The router will forward the packet out interface FastEthernet 0/1.2 tagged for VLAN 60.
• The router will forward the packet out interface FastEthernet 0/1.3 tagged for VLAN 60.
• The router will forward the packet out interface FastEthernet 0/1.3 tagged for VLAN 120.
• The router will not process the packet since the source and destination are on the same subnet.
• The router will drop the packet since no network that includes the source address is attached to the router.
6 A switch in a VTP domain sends an advertisement request. What will be the response?
• A configuration status reply will be issued from the closest client switch.
• A three-way handshake will establish a configuration session with the VTP server.
• Summary and subset advertisements will be sent by the VTP server.
• The configuration version number will be set to zero and all switches in the domain will issue advertisements regarding the state of their VLANs.
7 Which devices can be connected to a VLAN trunk? (Choose three.)
• a switch
• a hub
• a router
• a server with a special NIC
• a CSU/DSU
• a repeater
8 What should be done before moving a Catalyst switch to a new VTP management domain? (Choose three.)
• Verify that the new switch has a lower configuration revision number than the other switches in the domain.
• Reset the VTP counters to allow the switch to synchronize with the other switches in the domain.
• Download the VTP database from the VTP server in the new domain.
• Configure the VTP server in the domain to recognize the BID of the new switch.
• Select the correct VTP mode and version.
• Configure the switch with the name of the new management domain.
9 Which of the following must be used when configuring a router interface for VLAN trunking? (Choose three.)
• one subinterface per VLAN
• one physical interface for each subinterface
• one IP network or subnetwork for each subinterface
• one trunked link per VLAN
• a management domain for each subinterface
• a compatible trunking protocol encapsulation for each subinterface
10 By default, to which VLAN does a trunked link belong?
• the first VLAN defined
• the last VLAN defined
• all VLANs
• the lowest number VLAN
11
If trunking were not used in the network shown in the graphic, how many links would be required to carry the traffic for all the VLANs between the switches?
• 1
• 2
• 3
• 4
12
Host A sends a frame to host B over the network shown in the graphic. Each link has been labeled with a letter. On which links along the path between hosts A and B will a VLAN ID tag be included with the frame?
• C, E
• A, C, E
• C, E, F
• A, C, D, E

13
Which statements describe the network design shown in the graphic? (Choose three.)
• This design will not scale easily.
• This design exceeds the maximum number of VLANs that can be attached to a switch.
• Devices on the different VLANs can communicate through the router.
• This design requires the use of the ISL or 802.1q protocol on the links between the switch and the router.
• This design uses more switch and router ports than are necessary.
• The router merges the VLANs into a single broadcast domain.
14 What causes a VTP configured switch to issue a summary advertisement?
• A new host has been attached to a switch in the management domain.

• A five-minute update timer has elapsed.
• The advertisement revision number has reached n+1.
