You have implemented a firewall-based VLAN filter to map traffic from subnet to a VLAN named vlan_40. However, you have not been successful in getting the traffic mapped correctly. In addition, all traffic must be passed to the Layer 2 network.

Referring to the exhibit, which three commands are required to accomplish this behavior? (Choose three.)

  1. set interfaces ge-0/0/19.0 family ethernet-switching filter output assign_vlan

  2. set interfaces ge-0/0/19.0 family ethernet-switching filter input assign_vlan

  3. set vlans vlan_40 interface ge-0/0/19.0 mapping policy

  4. set vlans vlan_30 interface ge-0/0/19.0 mapping policy

  5. set interfaces ge-0/0/20 unit 0 family ethernet-switching port-mode trunk vlan members all

A new user#39;s Class 3 IP phone is connected to port ge-0/0/7 on an EX Series switch; however, it is not working.

Referring to the exhibit, what is the cause?

  1. The model of the EX Series switch being used supports PoE only on interfaces ge-0/0/0 through ge-0/0/6.

  2. The PoE port is set to class 0.

  3. The port has been shut down because the phone#39;s power requirements exceed the PoE power budget for the switch.

  4. The guard-band is insufficient.

Answer: C

Question No: 125 – (Topic 2)

Which two statements are correct about L2PT? (Choose two.)

  1. L2PT requires 802.1Q tunneling enablement to effectively tunnel L2 protocols.

  2. 802.1Q tunnels all L2 protocols by default.

  3. L2PT encapsulates L2 PDUs by enabling the ingress switch to rewrite the PDUs#39; source MAC addresses before forwarding them onto the service provider network.

  4. You cannot enable L2PT and VLAN translation on the same VLAN.

Answer: A,D

Question No: 126 – (Topic 2)
