JN0-649 Exam - Question 32


Click the Exhibit button.

Your network has an unmanaged switch between the hosts and your EX Series switch. After the traffic enters the EX Series switch, each host must be on a separate VLAN.

How would you accomplish this task?

Show Answer
Correct Answer: A

To accomplish the task of placing each host on a separate VLAN after the traffic enters the EX Series switch, you need to configure an input firewall filter on interface ge-0/0/3 to match the source MAC or IP address of the hosts to assign the VLANs. This approach ensures that the traffic is correctly categorized into the appropriate VLANs based on specific identifiers of the hosts. Configuring a trunk on interface ge-0/0/3 would not achieve the goal, as trunk mode is used for carrying VLAN-tagged traffic between switches, not for assigning VLAN tags based on host-specific criteria.

EX switches has VLAN action on ingress interfaces to forward traffic to specific VLAN. https://www.juniper.net/documentation/us/en/software/junos/routing-policy/topics/topic-map/firewall-filter-match-condtions-and-actions-qfx.html vlan VLAN-name Forward matched packets to a specific VLAN. NOTE: The vlan action is supported on ingress interfaces only.

trunk interfaces dont assign vlans on their own. besides, since the switch is unmanaged, the traffic from the 3 devices will be untagged and dropped on a trunk interface, unless you assign all the traffic to the native-vlan

The key is contained within answer C itself as the diagram leads one to think the devices already reside within their respective VLANs. “Configure interface ge-0/0/3 to a mode trunk to assign the VLANs. VLANs within a trunk interface can be allowed not assigned. This function is accomplished via answer A. This is a very tricky question especially the way the diagram is represented. 
A is the correct answer.
