Referring to the exhibit, you are asked to ensure that CE1 can communicate with CE2 using VLAN
150.
Which configuration meets this requirement on S1?
A.
user@S1# show
customer-a {
vlan-id 200;
dot1q-tunneling {
customer-vlans 150;
}
{master:0}[edit vlans]
B.
user@S1# show
customer-a {
vlan-id 150;
interface {
ge-0/0/0.0;
ge-0/0/1.0;
}
dot1q-tunneling {
customer-vlans 200;
}
{master:0}[edit vlans]
C.
user@S1# show
customer-a {
vlan-id 200;
interface {
ge-0/0/0.0;
ge-0/0/1.0;
}
dot1q-tunneling {
customer-vlans 150;
}
{master:0}[edit vlans]
D.
user@S1# show
customer-a {
vlan-id 150;
interface {
ge-0/0/0.0;
}
v200 {
vlan-id 200;
interface {
ge-0/0/1.0;
}
shouldn’t the answer be A
interfaces should be added in the S-VLAN. C is right.

I would say that access interface misses in A.
B. & C. contains the backbone interface which is wrong
D seems correct but i’m not 100% sure.
Wrong. Ingress and egress interfaces are in different vlans, thus in different L2 domains (no qinq cfg mentioned in D), therefore communication is not possible.
http://kb.juniper.net/InfoCenter/index?page=content&id=KB12259 examples suggest C.
