You have implemented a firewall-based VLAN filter to map traffic from subnet
192.168.40.0/24 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.)
A. set vlans vlan_30 interface ge-0/0/19.0 mapping policy
B. set interfaces ge-0/0/19.0 family ethernet-switching filter input assign_vlan
C. set vlans vlan_40 interface ge-0/0/19.0 mapping policy
D. set interfaces ge-0/0/19.0 family ethernet-switching filter output assign_vlan
E. set interfaces ge-0/0/20 unit 0 family ethernet-switching port-mode trunk vlan members all
正解：B,C,E

質問 2：
You manage your company's enterprise network using EX series switches. Your company wants to use Q in Q tunneling to correct remote customer sites together, which statement is correct about the scenario?
A. the default Ethernet type value is 0x9100
B. customer traffic is tunneled through the network using the C-VLAN-ID
C. the outside layer 2 frame is popped by the penultimate switch
D. you must enable L2PT to tunnel layer 2 protocol traffic
正解：D

質問 3：
Which two statements are correct about L2PT? (Choose two.)
A. L2PT encapsulates L2 PDUs by enabling the ingress switch to rewrite the PDUs' source
MAC addresses before forwarding them onto the service provider network.
B. L2PT requires 802.1Q tunneling enablement to effectively tunnel L2 protocols.
C. You cannot enable L2PT and VLAN translation on the same VLAN.
D. 802.1Q tunnels all L2 protocols by default.
正解：B,C

Traffic flows through your network, as shown in the exhibit. You have configured a rewrite rule on R1 to mark HTTP traffic with a specific DSCP value.
What must you do to ensure that the HTTP traffic preserves its DSCP value as it leaves your CoS domain?
A. Use rewrite rules mapping the HTTP traffic to the specific DSCP value on R2 and R3.
B. Use the default settings already in place on the device.
C. Use behavior aggregate classifiers mapping the HTTP traffic to the specific DSCP value on R1 and R2.
D. Use a rewrite rule mapping the HTTP traffic to the specific DSCP value on R3.
正解：B
