Practice question 417 of 440 · medium

Site A has two independent WANs and two tunnels to site B, but B has one WAN. Which failure remains a common outage for both tunnels?

Choose the single best answer.

  1. A.Failure of B’s single WAN connection.
  2. B.Failure of only A’s first WAN when its second path is working and authorized.
  3. C.Changing only A’s route preference while both its working paths remain valid.
  4. D.A supported rekey on one healthy tunnel that has a validated replacement path.
Show the answer and explanation

✓ Correct answer

  • Failure of B’s single WAN connection.

Both logical tunnels depend on B’s one underlay, so its failure defeats that partial redundancy. A validated second A-side path can cover a single A-WAN failure; a valid A-side preference change and ordinary supported rekey are not the identified common physical dependency.
