Practice question 418 of 440 · easy

Both VPN gateways have two WAN links. If every WAN cross-pair is intentionally configured, how many pairwise underlay paths are possible?

Choose the single best answer.

  1. A.Two, because each gateway can use only one WAN in every design.
  2. B.Eight, because every direction is counted as another gateway pair.
  3. C.One, because the IKE version fixes path count.
  4. D.Four.
Show the answer and explanation

✓ Correct answer

  • Four.

Two interfaces at A combined with two at B produce 2×2 = 4 cross-pairs. Directional SA state is separate from physical pairing. IKE version does not constrain this simple topology count to one.
