Options

• ANeighbors maintain communication with the restarting router.
• BThe restarting router sends gratuitous ARP for 30 seconds.

• C

• D
  85% (17)

Explanation

From the partial OSPF (Open Shortest Path First) configuration output: The router sends grace LSAs before it restarts: This is implied by the command 'set restart-mode graceful-restart'. When OSPF is configured with graceful restart, the router sends grace LSAs (Link State Advertisements) to inform its neighbors that it is restarting, allowing for a seamless transition without recalculating routes. Fortinet documentation on OSPF configuration clearly states that enabling graceful restart mode allows the router to maintain its adjacencies and routes during a brief restart period.
