Refer to the Exhibit.
In the exhibit, Site 1 is sending traffic on VLANs 100, 200, and 300. The provider operating switch S1 must configure Q-in-Q tunneling to transport VLANs 100 and 200 to Site2. The provider must configure switch S1 to block traffic received from site 1 on VLAN 300.Which configuration accomplishes this goal?
A.
{master:0}[edit vlans pv200]
user@S1# show
vlan-id 200;
interface {
ge-0/0/0.0;
ge-0/0/1.0;
}
dot1q-tunneling {
customer-vlans [ 100 200 ];
}
B.
{master:0}[edit vlans pv200]
user@S1# show
vlan-id [100 200];
interface {
ge-0/0/0.0 {
dot1q-tunneling {
block-vlans 300;
}
}
ge-0/0/1.0;
}
C.
{master:0}[edit vlans pv200]
user@S1# show
vlan-id 200;
interface {
ge-0/0/0.0;
ge-0/0/1.0;
}
dot1q-tunneling {
block-vlans 300;
}
D.
{master:0}[edit vlans pv200]
user@S1# show
vlan-id 200;
interface {
ge-0/0/0.0 {
dot1q-tunneling {
customer-vlans [ 100 200 ];
}
}
ge-0/0/1.0;
}

The second method you can use is the many-to-one bundling approach which maps only the defined C-VLAN tags to the configured S-VLAN. You use the customer-vlans option to specify which C-VLANs are mapped to the S-VLAN as shown in the configuration example below:
[edit vlans]
user@Bridge-A# show
v200 {
vlan-id 200;
interface {
ge-0/0/0.0;
ge-0/0/10.0;
}
dot1q-tunneling {
customer-vlans [ 100 160 ];
}
}
