You are asked to place employees that are in the sales group into their own VLAN called
Sales_VLAN with a VLAN ID of 123 on port ge-0/0/17. The VLAN must be assigned dynamically. After trying an initial configuration, you see that users in the sales group are not assigned to the Sales_VLAN.
Referring to the exhibit, which two configuration statements are needed on the EX Series switch to resolve this problem? (Choose two.)

In the exhibit, Host2 is the only host currently joining group 231.1.1.1, but S1 is still flooding the traffic to all hosts on VLAN 100.
What feature can be configured on S1 to limit the multicast flooding of traffic to only interested hosts on VLAN 100?
You notice that a number of IGMP leave group messages are passing through a BMA network and are impacting the network's performance.
What would you do to resolve this issue without affecting multicast traffic?
