Question No.71

What are two benefits of using 6to4 as an IPv6 transition method? (Choose two.)

  1. 6to4 tunnels allow isolated IPv6 domains to be remotely connected over IPv4 networks.

  2. Manual configuration (scalability) is easier.

  3. Point-to-multipoint automatic tunneling (automatic 6to4) is available.

  4. An infinite number of address spaces are allocated to an IPv6 subnet.

  5. Globally unique IPv4 addresses are not required.

Correct Answer: AC

Question No.72

  2. When redundant Layer 3 links, that are not part of a single EtherChannel or bundle, exist between distribution switches

  3. Between Distribution and Core switches when interfaces are configured with quot;no switchportquot;

  4. Between Distribution and Core switches when VSS is configured

Correct Answer: A

Question No.76

Which two elements comprise the backbone area while designing a new network utilizing IS-IS as

the interior gateway protocol? (Choose two)

  1. contiguous chain of Level 2 capable routers

  2. contiguous chain of Level1/Level 2 capable routers

  3. set of Level 2 configured interfaces

  4. contiguous Level 1 capable routers

  5. set of Level 1 configured interfaces

Correct Answer: AB



Backbone IS-IS does not have a backbone area like the OSPF area 0. The IS-IS backbone is a contiguous collection of Level 2-capable routers, each of which can be in a different area.


In most designs with routing hierarchy, the Level 2 routers are also Level 1 routers by virtue of their identification with a certain area. Therefore, in IS-IS, a router can function as Level 1-only or Level 2-only and possibly as both Level 1 and Level 2 (Level 1-2). Level 1-2 routers act as border routers to their respective areas, providing connectivity to other areas. The Level 2 backbone is essentially a virtual IS-IS area consisting of routers engaged in Level 2 routing.
