The answer is `set add-route enable` on the spoke’s phase1 interface. This setting is required because ADVPN shortcut tunnels rely on the spoke accepting dynamic route offers from the hub; without it, the spoke will ignore shortcut initiation messages and never build a direct tunnel to another spoke, even when traffic patterns demand it. On the Fortinet NSE 7 Advanced Security NSE7 exam, this concept tests your understanding of how ADVPN control-plane signaling works in a hub-and-spoke topology with dynamic public IPs—a common trap is assuming the hub’s configuration alone is sufficient, when in fact the spoke must explicitly enable route addition to trigger the shortcut. Remember the mnemonic “Spokes need to add routes to accept shortcuts” to avoid missing this critical toggle.
NSE7 Advanced VPN and Zero Trust Practice Question
This NSE7 practice question tests your understanding of advanced vpn and zero trust. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A FortiGate administrator is configuring Auto Discovery VPN (ADVPN) in a hub-and-spoke topology. Spokes are FortiGates with dynamic public IPs. Which setting is required on the spoke for it to automatically initiate shortcut tunnels to other spokes when needed?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
set add-route enable
ADVPN shortcut tunnels require the spoke to accept shortcut offers from the hub. Setting 'set add-route enable' on the phase1 interface allows the spoke to install routes for shortcuts. Without this, the spoke will not create shortcut tunnels even if it receives the offer.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
set net-device disable
Why it's wrong here
This prevents the tunnel interface from appearing as a network interface; it does not affect shortcuts.
✗
set mode aggressive
Why it's wrong here
Aggressive mode is an IKE authentication mode, not related to ADVPN shortcuts.
✓
set add-route enable
Why this is correct
This command on the phase1-interface allows dynamic route injection for shortcut tunnels.

✗
set shortcut-station enable
Why it's wrong here
This is not a valid FortiGate command.

TExam Day Tips
→Underline the problem statement mentally.
→Watch for words such as best, first, most likely and least administrative effort.
→Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A practitioner preparing for the NSE7 exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.
