問題文
A controller picks the address of its exit by itself from the static routes that match the subnet of the link for the redundancy management. Which of the matching routes does it draw that address from, and what becomes of the failover of the exit where a match is absent?
選択肢

- The gateway is drawn from the route with the widest of the masks, and the failover of the gateway sits ready while a match is absent by the book.
