Practice question 322 of 440 · medium

A volumetric flood saturates the upstream WAN link before FortiGate. Which limitation applies to local IPS?

Choose the single best answer.

  1. A.Adding every signature increases the upstream link capacity
  2. B.Packet logging prevents incoming packets reaching the ISP
  3. C.Deep inspection eliminates all network floods
  4. D.It cannot restore upstream bandwidth already consumed
Show the answer and explanation

✓ Correct answer

  • It cannot restore upstream bandwidth already consumed

Inspection cannot create upstream capacity. More signatures, packet logging and decryption do not remove that bottleneck.
