   You have an IS-IS network with two paths to a destination. Path A has a total metric of 100, and Path B has a total metric of 100. Both paths are learned via the same level. What will the router do?

   • AInstall only Path B, because it has a higher metric.
   • BInstall only Path A, because it was learned first.
   • CInstall both paths in the routing table and load-balance traffic across them.
   • DInstall neither path, because the router cannot decide between equal-cost paths.

   You have an IS-IS network with multiple areas. You want to ensure that routes from one area are advertised into another area with their original metrics, so that the receiving area can make informed path decisions. What mechanism should you use?

   • AUsing wide metrics, which automatically propagate routes between areas with their metrics.
   • BDefault route advertisement, which sends a default route into the other area, but this does not carry specific route metrics.
   • CRedistribution, which copies routes from one routing protocol to another, but this does not preserve IS-IS metrics.
   • DRoute leaking, which allows Level 1 routes to be advertised into Level 2 and vice versa, preserving the original metric values.

   You are configuring a new IS-IS network and need to support link metrics up to 100000. Which metric style should you use?

   • AWide metrics, because they support values up to 2^24-1 (16777215).
   • BBoth narrow and wide metrics, because you can use narrow for small values and wide for large values.
   • CNarrow metrics, because they support values up to 63.
   • DNarrow metrics with a multiplier, because you can scale the metric values.

   In which scenario is the use of wide metrics most appropriate?

   • AA network with a small number of routers where all link costs are below 10.
   • BA network where interface metrics need to reflect high-bandwidth links with values exceeding 63.
   • CA network that requires the use of the default metric of 10 for all interfaces.
   • DA network that must interoperate with legacy IS-IS routers that only support narrow metrics.
