Module 4

Question 1

What are the three inter-VLAN routing options?

Question 2

What is legacy inter-vlan routing? What is its scalability?

Question 3

what is router-on-a-stick routing? What is its scalability?

Question 4

What is inter-vlan routing on a layer 3 switch? What is its scalability?

Question 5

What is needed for hosts to communicate with other VLANs?

Answer 5

A router or a layer 3 switch to provide routing services

Question 6

What is the limitation of legacy inter-vlan routing?

Answer 6

It is not reasonably scalable because routers have a limited number of physical interfaces. This would require one physical router interface per VLAN quickly exhausts the physical interface capability of a router.

Question 7

How does the router on a stick overcome the legacy inter-vlan limitations?

Question 8

What is the scaling limit for a router on a stick?

Answer 8

50 VLANs

Question 9

Explain how a router on a stick traffic is routed?

Question 10

What is the modern method of performing inter-vlan routing?

Answer 10

By using layer 3 switches and switched virtual interfaces (SVIs)

Question 11

What is a switched virtual interface (SVI)?

Answer 11

A virtual interface that is configured on a layer 3 switch.
