Question 1

Question 2

Question 3

Explanation

To enabe encapsulation on a subinterface we have type the “encapsulation” command under that subinterface, not the main interface. An example of configuring encapsulation on subinterface of Fa0/1 is shown below:

Router(config)#interface f0/0
Router(config-if)#no shutdown

(Note: The main interface f0/0 doesn’t need an IP address but it must be turned on)

Router(config)#interface f0/0.0
Router(config-subif)#encapsulation dot1q 10
Router(config-subif)#ip address 192.168.1.1 255.255.255.0
Router(config-subif)#interface f0/0.1
Router(config-subif)#encapsulation dot1q 20
Router(config-subif)#ip address 192.168.2.1 255.255.255.0

Note: In the “encapsulation dot1q 10”, number 10 is the VLAN applied to that subinterface. Or you can understand that the subinterface belongs to that VLAN.

Question 4

Explanation

The causes of slow interVLAN are usually duplex mismatch or collision domain issues, user misconfiguration.

Question 5

Question 6

Question 7

Question 8

Explanation

This question only asks about enable router-on-stick on a switch, not a router. We don’t have subinterface on a switch so B is not a correct answer.
