   A service provider is running IS-IS with narrow metrics. They need to support a link with a metric of 100. What is the best way to achieve this?

   • AUse a metric of 63 and rely on the default metric.
   • BUse a route policy to modify the metric during redistribution.
   • CUse a loopback interface to create a virtual link with a higher metric.
   • DChange the metric style to wide on all routers.

   An ISP is migrating its IS-IS backbone from IPv4-only to dual-stack. The network team wants to minimize operational complexity and ensure that IPv4 and IPv6 always use the same paths. They plan to enable IPv6 on all existing IS-IS interfaces. Which configuration approach best meets their requirement?

   • AUse separate IS-IS processes for IPv4 and IPv6.
   • BEnable multitopology IS-IS for IPv6 on all routers.
   • CConfigure IPv6 on only the core routers and use redistribution into IPv4.
   • DEnable single-topology IS-IS for IPv6 on all routers.
