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?
- A. 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.
- B. Configure an output firewall filter on interface ge-0/0/1 to match the destination MAC or IP address of the hosts to assign the VLANs.
