   Which statement correctly describes the compatibility between narrow and wide metric styles in IS-IS?

   • AA router using wide metrics can understand narrow metrics, but a router using narrow metrics cannot understand wide metrics.
   • BNarrow and wide metrics can be used interchangeably on the same link without any configuration.
   • CNarrow and wide metrics are completely incompatible and cannot be used in the same network.
   • DA router using narrow metrics can understand wide metrics but will truncate the value.

   A network administrator is configuring IS-IS on a router and wants to ensure that a specific interface is preferred over others. The administrator decides to set an explicit metric. Which statement accurately describes the effect of setting an explicit metric on an interface?

   • AThe explicit metric overrides the default metric of 10 for that interface.
   • BThe explicit metric is ignored if auto-cost is enabled.
   • CThe explicit metric only affects level 1 routing, not level 2.
   • DThe explicit metric is added to the default metric of 10.

   How are IS-IS metrics propagated to other routers in the network?

   • AThey are sent in separate metric update packets.
   • BThey are configured manually on every router in the network.
   • CThey are included in the Link State PDUs (LSPs) that are flooded to other routers.
   • DThey are propagated using the Routing Information Protocol (RIP).

   How does the external metric affect route preference in IS-IS compared to an internal metric?

   • AExternal and internal metrics are treated equally in route preference.
   • BExternal metrics are always preferred over internal metrics.
   • CThe preference depends on the metric value, not on whether it is internal or external.
   • DInternal metrics are always preferred over external metrics, regardless of the metric value.

   An IS-IS network has two paths to a destination. Path A is an internal route with a metric of 100. Path B is an external route with a metric of 50. Which path will be preferred by the SPF algorithm?

   • AThe path with the lower interface metric is preferred, regardless of the total metric.
   • BBoth paths are equally preferred, and load balancing is performed.
   • CPath A, because internal routes are always preferred over external routes.
   • DPath B, because it has a lower metric.
