A network engineer is designing a network for AS100. The design should ensure that all traffic enters AS100 via link 1 unless there is a network failure. In the event of a failure, link 2 should function as the path for incoming traffic. Which solution should the design include?

A.

Modify the next-hop attribute on R3.

B.

Use AS-Path prepending on R3.

C.

Modify the next-hop attribute on R4.

D.

Use AS-Path prepending on R4

IPFIX

B.

static telemetry

C.

on-change subscription

D.

periodic subscription

An engineer is creating a design to enable IPv6 to run on an existing IPv4 IS-IS network.
The IPv4 and IPv6 topologies will match exactly, and the engineer plans to use the same
router levels for each protocol per interface. Which IS-IS design is required?

A.

single topology without enabling transition feature

B.

single topology with transition feature enabled

C.

multi topology with transition feature enabled

D.

multi topology without enabling transition feature
