Final Exam IT 341 Chapter 4

Inter-VLAN Routing

process of forwarding network traffic from one VLAN to another VLAN

Which solution is the most scalable solution for medium to large organizations?

layer 3 router and switch

Why is a SVI created?

its created for a VLAN that exists on a switch, it performs the same functions for a VLAN as a router interface would

Put the following steps in order for a layer 3 switch config

Enable IP Routing

Configure access ports

Create VLANs

Create SVI VLAN Interfaces

Step 1: create VLANs

Step 2: create the SVI VLAN Interfaces

Step 3: configure access ports

Step 4: enable ip routing

Drag each function to correct device?

router:

-routes packets between diff ip subnets

-typically used at network edges

layer 3 switch:

-can perform inter-vlan routing

-provides hardware-based packet forwarding

-usually configured with VLAN interfaces

Label the correct decision point that each device uses to forward traffic

Options:

-MAC Address Table

-Routing Table

-IP Address

-VLAN ID

-ARP cache

Drop Zones:

-Layer 2 Switch

-Layer 3 switch

-Router

-MAC Address Table: Layer 2 Switch

-VLAN ID: Layer 2 Switch

-Routing Table: Layer 3 Switch

-IP Address: Layer 3 Switch

-Routing Table: router

-IP Address: router

Match each inter-VLAN routing method to the device that can perform it

Options:

-Router on a Stick

-SVIs

-Routed Ports

-Sub-Interfaces

Drop Zones:

-router

- layer 3 switch

-Router on a Stick: router

-sub interfaces: router

-SVIs: layer 3 switch

-routed ports: layer 3 switch

Match each interface type under the correct device

Options:

-VLAN 10

-FastEthernet 0/0

-GigabitEthernet 1/1

-VLAN 1

-Serial 0/1/0

Drop Zones:

-router

-layer 3 switch

-VLAN 10: layer 3 switch

-FastEthernet 0/0: router

-GigabitEthernet 1/1: layer 3 switch

-VLAN 1: layer 3 switch

-Serial 0/1/0: router

Why are the trunk links necessary?

its required for forward traffic within and between the VLANs

R1, S1, and S2 have initial basic config. Why can’t PC1 and PC2 ping each other?

They cannot ping each other because they are on separate networks

How can you enable devices to ping each other?

switches must be configured with VLANs and trunking

router must be configured for inter-VLAN routing

What are the 3 inter-vlan routing options

-legacy inter-vlan routing

-router on a stick

-layer 3 switch using SVIs
