   A network engineer is troubleshooting a routing loop in an IS-IS area. The engineer suspects that a router is not flooding LSPs correctly. Which action would most directly help the engineer verify that LSPs are being flooded correctly?

   • ACheck the LSP database on multiple routers to ensure they all have the same LSPs with the same sequence numbers.
   • BIncrease the LSP refresh interval on all routers.
   • CDisable CSNP generation on all routers.
   • DChange the overload bit on all routers.

   Which statement correctly describes the role of the link-state database in IS-IS route calculation?

   • BIt provides the complete topology information required by the SPF algorithm to compute loop-free paths.
   • CIt is used only for neighbor discovery and not for path computation.
   • DIt is used only for building the forwarding table, not for route calculation.
