Pass JUNIPER JN0-694 Exam Question 1
You are implementing Q-in-Q tunneling on an EX Series switch. You want the tunnel to support all C-VLANs; however, only some VLANs are able to send traffic across the tunnel. Switch-1 has the following configuration:

[edit vlans]
user@Switch-1# show
v100 {
vlan-id 100;
interface {
ge-0/0/0.10;
ge-0/0/1.20;
}
dot1q-tunneling {
customer-vlans [ ];
}
}
What would solve this problem?

A. Add family ethernet-switching to the tunnel-side interface on Switch-1.
B. Implement RSTP.
C. Q-in-Q tunneling will not work in this scenario; use a Layer 2 VPN instead.
D. Remove the customer-vlans statement.

Answer: C
