You are troubleshooting an OSPF adjacency problem between R1 and R2.
Referring to the exhibit, what is causing this OSPF adjacency problem?
A. There is a dead interval mismatch.
B. There is an MTU mismatch.
C. There is an LSA refresh timer mismatch.
D. There is a hello interval mismatch.
正解：B

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