• Question 222:

  Your customer requests that you provide a transparent Layer 2 service between two of their remote locations. This service must allow the customer to pass tagged traffic from multiple VLANs. You decide to use Q-in-Q tunneling on the two provider edge MX Series routers that connect to the customer's CE devices. Which two statements are true? (Choose two.)

  A. As traffic leaves the Q-in-Q tunnel, the S-VLAN tag will be removed from the frames.

  B. As traffic enters the Q-in-Q tunnel, an S-VLAN tag will be added to the frames.

  C. As traffic enters the Q-in-Q tunnel, a C-VLAN tag will be added to the frames.

  D. As traffic leaves the Q-in-Q tunnel, the C-VLAN tag will be removed from the frames.

  Correct Answer: AB

• Question 224:

  You are deploying IS-IS in your network to enable the routing of only IPv6. Assume that the loopback interface has been properly configured.

  What is the minimum required configuration to enable only IPv6 routing in IS-IS?

  A. user@host# show protocols isis rib-group inet6; interface ge-0/0/0.0; interface lo0.0 { passive; } user@host# show interfaces ge-0/0/0 unit 0 { family inet6 address fd85:5944:1aee:026::1/64; }

  B. user@host# show protocols isis interface ge-0/0/0.0; interface lo0.0 { passive; } user@host# show interfaces ge-0/0/0 unit 0 { family iso; family inet6 address fd85:5944:1aee:026::1/64; }

  C. user@host# show protocols isis no-ipv4-routing; interface ge-0/0/0.0 interface lo0.0 { passive; } user@host# show interfaces ge-0/0/0 unit 0 { family iso; family inet6 address fd85:5944:1aee:026::1/64; }

  D. user@host# show protocols isis no-ipv4-routing; interface ge-0/0/0.0; interface lo0.0 { passive; } user@host# show interfaces ge-0/0/0 unit 0 { family iso; family inet6; }

  E. user@host# show protocols isis traffic-engineering { family inet6 { shortcuts; } } interface ge-0/0/0.0;

  interface lo0.0 {
