Which two statements about an auxiliary session ate true? (Choose two.)

Question

Options

• AWith the auxiliary session selling disabled, only auxiliary sessions are offloaded.
• BWith the auxiliary session setting enabled, ECMP traffic is accelerated to the NP6 processor.
• CWith the auxiliary session setting enabled, two sessions are created in case of routing change.
• DWith the auxiliary session setting disabled, for each traffic path, FortiGate uses the same auxiliary

• A
  6% (3)
• B
  78% (42)
• D
  17% (9)

Explanation

Options B and C are correct because they accurately describe the behavior when the auxiliary session setting is enabled. When enabled, FortiGate offloads ECMP (Equal Cost Multi-Path) traffic to the NP6 hardware processor for acceleration (B), and it creates two sessions - a primary and an auxiliary - so that if a routing change occurs, the alternate path already has an established session ready (C).

Option A is wrong because when the auxiliary session setting is disabled, no auxiliary sessions are created at all - so nothing is being "offloaded" via auxiliary sessions. The statement inverts the logic.

Option D is wrong because when the setting is disabled, FortiGate creates only a single session per flow and relies solely on that session regardless of routing changes - there is no auxiliary session involved. D is also incomplete as written, which is a clue to eliminate it.

Memory tip: Think of "auxiliary" like a spare tire - when the feature is enabled, you carry a second session (spare) in case the route changes. When disabled, you ride on one session only, with no backup. ECMP + NP6 acceleration are the two hardware-level benefits that kick in only when the spare tire is "in the trunk."
