   In a multi-level IS-IS network, you have a Level 1 router that needs to reach a destination in another area. The Level 1 router has a default route to the nearest Level 2 router. However, you want the Level 1 router to use a specific Level 2 router that provides a better path to the destination. What should you configure?

   • ARoute leaking from Level 2 to Level 1, which advertises the specific route with its metric into Level 1.
   • BA static route on the Level 1 router pointing to the desired Level 2 router.
   • CConfigure the Level 1 router to use wide metrics, which automatically provides more specific routes.
   • DIncrease the metric on the default route to make it less preferred.

   In a mixed IS-IS environment with both narrow and wide metric routers, what is a common compatibility issue?

   • ANarrow metric routers reject LSPs from wide metric routers, causing network partitions.
   • BRouters using wide metrics cannot form adjacencies with narrow-metric routers.
   • CWide metric routers automatically convert to narrow metrics when they detect narrow-metric neighbors.
   • DRouters using narrow metrics cannot understand wide metric TLVs, potentially causing routing loops.

   In an IS-IS network, you have two paths to a destination: Path A has a total metric of 50, and Path B has a total metric of 60. Both paths are learned via the same IS-IS level. Which path will the router install in its routing table?

   • ANeither path, because the router will wait for a better path to be advertised.
   • BPath B, because it has a higher metric and is considered more reliable.
   • CBoth paths, because IS-IS supports equal-cost multipath (ECMP) only when metrics are equal, but here they are not equal, so only the lower metric path is used.
   • DPath A, because it has the lower total metric.

   What is the role of route leaking in IS-IS?

   • AIt allows routes from one level to be advertised into another level with a specified metric.
   • BIt removes external routes from the routing table.
   • CIt prevents routes from being advertised between levels to reduce routing table size.
   • DIt changes the metric of routes to make them less preferred.
