VLAN and Inter-VLAN Routing Quiz

A high school uses VLAN15 for the laboratory network and VLAN30 for the faculty network. What is required to enable communication between these two VLANs while using the router-on-a-stick approach?

• A multilayer switch is needed.

• A router with at least two LAN interfaces is needed.

• Two groups of switches are needed, each with ports that are configured for one VLAN.

• A switch with a port that is configured as a trunk is needed when connecting to the router.

When routing a large number of VLANs, what are two disadvantages of using the router-on-a-stick inter-VLAN routing method rather than the multilayer switch inter-VLAN routing method? (Choose two.)

• Multiple SVIs are needed.

• A dedicated router is required.

• Router-on-a-stick requires subinterfaces to be configured on the same subnets.

• Router-on-a-stick requires multiple physical interfaces on a router.

• Multiple subinterfaces may impact the traffic flow speed.

Refer to the exhibit. A network administrator is verifying the configuration of inter-VLAN routing. Users complain that PCs on different VLANs cannot communicate. Based on the output, what are two configuration errors on switch interface Gi1/1? (Choose two.)

• Gi1/1 is in the default VLAN.

• Voice VLAN is not assigned to Gi1/1.

• Gi1/1 is configured as trunk mode.

• Negotiation of trunking is turned on on Gi1/1.

• The trunking encapsulation protocol is configured wrong.

Refer to the exhibit. A network administrator is verifying the configuration of inter-VLAN routing. Users complain that PC2 cannot communicate with PC1. Based on the output, what is the possible cause of the problem?

• Gi0/0 is not configured as a trunk port.

• The command interface GigabitEthernet0/0.5 was entered incorrectly.

• There is no IP address configured on the interface Gi0/0.

• The no shutdown command is not entered on subinterfaces.

• The encapsulation dot1Q 5 command contains the wrong VLAN.

Refer to the exhibit. A network administrator has configured router CiscoVille with the above commands to provide inter-VLAN routing. What type of port will be required on a switch that is connected to Gi0/0 on router CiscoVille to allow inter-VLAN routing?

• routed port

• access port

• trunk port

• SVI

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 802.1Q encapsulation on subinterfaces.

Refer to the exhibit. A router-on-a-stick configuration was implemented for VLANs 15, 30, and 45, according to the show running-config command output. PCs on VLAN 45 that are using the 172.16.45.0 /24 network are having trouble connecting to PCs on VLAN 30 in the 172.16.30.0 /24 network. Which error is most likely causing this problem?

• The wrong VLAN has been configured on GigabitEthernet 0/0.45.

• The command no shutdown is missing on GigabitEthernet 0/0.30.

• The GigabitEthernet 0/0 interface is missing an IP address.

• There is an incorrect IP address configured on GigabitEthernet 0/0.30.

What is a characteristic of a routed port on a Layer 3 switch?

• It supports trunking.

• It is not assigned to a VLAN.

• It is commonly used as a WAN link.

• It cannot have an IP address assigned to it.

Refer to the exhibit. A network administrator needs to configure router-on-a-stick for the networks that are shown. How many subinterfaces will have to be created on the router if each VLAN that is shown is to be routed and each VLAN has its own subinterface?

• 1

• 2

• 3

• 4

• 5

A technician is configuring a new Cisco 2960 switch. What is the effect of issuing the BranchSw(config-if)# mdix auto command?

• It automatically adjusts the port to allow device connections to use either a straight-through or a crossover cable.

• It applies an IPv4 address to the virtual interface.

• It applies an IPv6 address to the virtual interface.

• It permits an IPv6 address to be configured on a switch physical interface.

• It updates the MAC address table for the associated port.
