A PC is to access a web server on another network. Which inter-VLAN method will provide the highest bandwidth at Layer 3 and also provide a default gateway for the PC?
multilayer switch with routing enabled
2
Which scalable method must be implemented in order to provide inter-VLAN routing on a switched network with more than 1000 VLANs?
routing traffic internally to a Layer 3 switch device
3
When configuring a router as part of a router-on-a-stick inter-VLAN routing topology, where should the IP address be assigned?
to the subinterface
4
A small college uses VLAN 10 for the classroom network and VLAN 20 for the office network. What is needed to enable communication between these two VLANs while using legacy inter-VLAN routing?
A router with at least two LAN interfaces should be used.
5
What is a disadvantage of using multilayer switches for inter-VLAN routing?
Multilayer switches are more expensive than router-on-a-stick implementations.
6
Which type of inter-VLAN communication design requires the configuration of multiple subinterfaces?
router on a stick
7
What is a disadvantage of using router-on-a-stick inter-VLAN routing?
does not scale well beyond 50 VLANs
8
What is the meaning of the number 10 in the encapsulation dot1Q 10 native router subinterface command?
the VLAN ID
9
While configuring inter-VLAN routing on a multilayer switch, a network administrator issues the no switchport command on an interface that is connected to another switch. What is the purpose of this command?
to create a routed port for a single network
10
network administrator enters the following command sequence on a Cisco 3560 switch. What is the purpose of these commands? Switch(config)# interface gigabitethernet 0/1 Switch(config-if)# no switchport
to make the Gi0/1 port a routed port
11
What operational mode should be used on a switch port to connect it to a router for router-on-a-stick inter-VLAN routing?
trunk
12
Which sentence correctly describes the SVI inter-VLAN routing
An SVI is needed for each VLAN.
13
How is traffic routed between multiple VLANs on a multilayer switch?
Traffic is routed via internal VLAN interfaces.
14
What is required to perform router-on-a-stick inter-VLAN routing?
a router that is configured with multiple subinterfaces
15
An administrator was troubleshooting a router-on-a-stick topology and concluded that the problem was related to the configuration of VLANs on the router subinterfaces. Which two commands can the administrator use in the router to identify the problem? (Choose two.)
show ip interface, show running-config
16
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? Use a hub to connect the four VLANS with a FastEthernet interface on the router.
Implement a router-on-a-stick configuration.
17
What distinguishes traditional legacy inter-VLAN routing from router-on-a-stick?
Traditional routing uses one port per logical network, whereas a router-on-a-stick uses subinterfaces to connect multiple logical networks to a single router port.
18
Subinterface G0/1.10 on R1 must be configured as the default gateway for the VLAN 10 192.168.10.0/24 network. Which command should be configured on the subinterface to enable inter-VLAN routing for VLAN 10?
encapsulation dot1q 10
19
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.
20
What are the steps that must be completed in order to enable inter-VLAN routing using router-on-a-
Create the VLANs on the switch to include port membership assignment and configure subinterfaces on the router matching the VLANs.
21
What two statements are true regarding the use of subinterfaces for inter-VLAN routing? (Choose two.)
Fewer router Ethernet ports required than in traditional inter-VLAN routing, Less complex physical connection than in traditional inter-VLAN routing
22
Which router-on-a-stick command and prompt on R1 correctly encapsulates 802.1Q traffic for VLAN 20?
R1(config-subif)# encapsulation dot1q 20
23
What are two disadvantages of using the router-on-a-stick inter-VLAN routing method in a large network? (Choose two.)
A dedicated router is required., It does not scale well.
24
What is a characteristic of a routed port on a Layer 3 switch? (Choose two.)
It requires the switchport mode access interface config command., It requires the no switchport interface config command.
25
25. What are two advantages of using a Layer 3 switch with SVIs for inter-VLAN routing? (Choose two.)
A router is not required., It switches packets faster than using the router-on-a-stick method.
