1. What are the steps which must be completed in order to enable inter-VLAN routing using router-on-a-stick?
Create the VLANs on the switch to include port membership assignment and configure subinterfaces on the router matching the VLANs.
Refer to the exhibit. R1 is routing between networks 192.168.10.0/28 and 192.168.30.0/28. PC1 can ping R1 interface F0/1, but cannot ping PC3. What is causing this failure?
The PC3 network address configuration is incorrect.
3. Which statement is true about ARP when inter-VLAN routing is being used on the network?
When router-on-a-stick inter-VLAN routing is in use, the router returns the MAC address of the physical interface in response to ARP requests.
4. In which situation could individual router physical interfaces be used for InterVLAN routing, instead of a router-on-a-stick configuration?
a network with a limited number of VLANs
Refer to the exhibit. Switch1 is correctly configured for the VLANs that are displayed in the graphic. The configuration that is shown was applied to RTA to allow for interVLAN connectivity between hosts attached to Switch1. After testing the network, the administrator logged the following report: Hosts within each VLAN can communicate with each other. Hosts in VLAN5 and VLAN33 are able to communicate with each other. Hosts connected to Fa0/1 through Fa0/5 do not have connectivity to host in other VLANs. Why are hosts connected to Fa0/1 through Fa0/5 unable to communicate with hosts in different VLANs?
The router was not configured to forward traffic for VLAN2.
6. What is important to consider while configuring the subinterfaces of a router when implementing inter-VLAN routing?
The IP address of each subinterface must be the default gateway address for each VLAN subnet.
Refer to the exhibit. Which two statements are true about the operation of the subinterfaces? (Choose two.)
Incoming traffic with VLAN ID 0 is processed by interface fa0/0.
Traffic inbound on this router is processed by different subinterfaces, depending on the VLAN from which the traffic originated.
Refer to the exhibit. The commands for a router to connect to a trunked uplink are shown in the exhibit. A packet is received from IP address 192.168.1.54. 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 0/1.2 tagged for VLAN 60.
Refer to the exhibit. PC1 has attempted to ping PC2 but has been unsuccessful. What could account for this failure?
The encapsulation command on the R1 F0/0.3 interface is incorrect.
Refer to the exhibit. What two conclusions can be drawn from the output that is shown? (Choose two.)
Both of the directly connected routes that are shown will share the same physical interface of the router.
Inter-VLAN routing between hosts on the 172.17.10.0/24 and 172.17.30.0/24 networks is successful on this network.
Refer to the exhibit. Which three statements describe the network design shown in the exhibit? (Choose three.)
This design will not scale easily.
This design uses more switch and router ports than are necessary.
If the physical interfaces between the switch and router are operational, the devices on the different VLANs can communicate through the router.
12. Devices on the network are connected to a 24-port Layer 2 switch that is configured with VLANs. Switch ports 0/2 to 0/4 are assigned to VLAN 10. Ports 0/5 to 0/8 are assigned to VLAN 20, and ports 0/9 to 0/12 are assigned to VLAN 30. All other ports are assigned to the default VLAN. Which solution allows all VLANs to communicate between each other while minimizing the number of ports necessary to connect the VLANs?
Add a router to the topology and configure one FastEthernet interface on the router with multiple subinterfaces for VLANs 1, 10, 20, and 30.
Refer to the exhibit. Port Fa0/0 on router R1 is connected to port Fa0/1 on switch S1. After the commands shown are entered on both devices, the network administrator determines that the devices on VLAN 2 are unable to ping the devices on VLAN 1. What is the likely problem?
R1 is configured for router-on-a-stick, but S1 is not configured for trunking.
14. A router has two FastEthernet interfaces and needs to connect to four VLANs in the local network. How can this be accomplished using the fewest number of physical interfaces without unnecessarily decreasing network performance?
Implement a router-on-a-stick configuration.
15. What distinguishes traditional routing from router-on-a-stick?
Traditional routing uses one port per logical network. Router-on-a-stick uses subinterfaces to connect multiple logical networks to a single router port.
16. What two statements are true regarding the use of subinterfaces for inter-VLAN routing? (Choose two.)
fewer router ports required than in traditional inter-VLAN routing
less complex physical connection than in traditional inter-VLAN routing
17. Which three elements must be used when configuring a router interface for VLAN trunking? (Choose three.)
one subinterface per VLAN
one IP network or subnetwork for each subinterface
a compatible trunking protocol encapsulation for each subinterface
Refer to the exhibit. The network administrator correctly configures RTA to perform inter-VLAN routing. The administrator connects RTA to port 0/4 on SW2, but inter-VLAN routing does not work. What could be the possible cause of the problem with the SW2 configuration?
Port 0/4 is configured in access mode.
19. Which two statements are true about the interface fa0/0.10 command? (Choose two.)
The command is used in the configuration of router-on-a-stick inter-VLAN routing.
The command configures a subinterface.
Refer to the exhibit. All devices are configured as shown in the exhibit. PC2 can successfully ping the F0/0 interface on R1. PC2 cannot ping PC1. What might be the reason for this failure?
S1 interface F0/8 is in the wrong VLAN.
