Which configuration must be applied so that VLANs 2 and 3 communicate (CCNA 200-301)
Refer to the exhibit. Configurations for the switch and PCs are complete.
Which configuration must be applied so that VLANs 2 and 3 communicate back and forth?
A. interface GigabitEthernet0/0 ip address 10.10.2.10 255.255.252.0
B. interface GigabitEthernet0/0.10 encapsulation dot1Q 3 ip address 10.10.2.10 255.255.254.0
C. interface GigabitEthernet0/0.3 encapsulation dot1Q 3 native ip address 10.10.2.10 255.255.252.0
D. interface GigabitEthernet0/0.3 encapsulation dot1Q 10 ip address 10.10.2.10 255.255.255.252
Solution
Correct answer: B. interface GigabitEthernet0/0.10 encapsulation dot1Q 3 ip address 10.10.2.10 255.255.254.0.
Given that the configuration for VLAN 2 is already set, configuring VLAN 3 on the router using the correct IP addressing (10.10.2.10 255.255.254.0) completes the setup for inter-VLAN communication.
