One of the 192 · item RTG-002

A whole question, with the answer and the source.

This is not a teaser. It is reproduced here exactly as it appears in the bank: the stem, all four options, the keyed answer, the full explanation, and the Fortinet page it was written from.

RTG-002 · Routing · single answer FortiOS 7.6 · bank 1.6.51

A FortiGate has several routes whose destination prefixes could match the same packet. In what order does FortiGate apply the route-selection criteria to determine the best route?

  • Most specific prefix first, then the lowest administrative distance, then metric and priority Correct
  • Lowest administrative distance first, then the most specific prefix, then priority
  • Lowest priority value first, then the lowest administrative distance, then the most specific prefix
  • Lowest metric first, then the most specific prefix, then the administrative distance

Explanation

The best route is the most specific route to the destination (longest prefix match). Only when FortiGate finds duplicate routes - multiple routes to the same destination - does it use route attributes as tiebreakers: administrative distance is the first tiebreaker, metric breaks ties, and priority breaks ties between equal-distance duplicate static routes. The remaining options invert this order: distance, metric, and priority are never compared across routes of different prefix lengths, because those routes are not duplicates and are not competing for the same routing table entry.

After a session

You find out which domain to go back to.

Every session ends with a score per blueprint domain, not a single number. A 71% overall that hides a 55% in one domain is the result worth knowing about. The domains below are the real ones for NSE 4; the percentages are made up, to show the shape of the screen.

Example only — invented figures, real domains

  1. Deployment and System Configuration 78%
  2. Firewall Policies and Authentication 61%
  3. Content Inspection 84%
  4. Routing 92%
  5. VPNs 55%

Timed mode draws to the published domain weightings. Untimed study mode shows the explanation and the source as you go. Fortinet does not publish the cut score for this exam, so neither do we — sessions are scored against a 70% mark we chose as a working target, and it is labeled as an estimate inside the app.

Sourcing

How these questions are written.

Grindstone Prep is a small independent publisher. Every question and every explanation here is written by a 20-year industry veteran with extensive network and security experience, checked against a primary source before it ships, with the citation left attached to the question where you can see it. If a question here is wrong, one person is responsible for it, and that is deliberate.

Questions are written from the FortiOS 7.6.0 Administration Guide, the FortiOS 7.6.0 CLI Reference and Log Message Reference on docs.fortinet.com, Fortinet Knowledge Base articles, Fortinet’s published exam description for NSE4_FGT_AD-7.6, and hands-on verification on a FortiGate. They are never taken from a real examination, from a braindump site, or from another vendor’s practice product. An item that cannot be traced to a primary source is deleted rather than published.

The full methodology, in detail — what is used, what is refused, and how an item gets from a source page to the bank.

Before you buy: the FortiOS 8.0 exam

Fortinet has announced a successor to this exam, NSE 4 — FortiOS 8.0 Administrator, on its own release-notice page. It has published no last delivery date for the FortiOS 7.6 exam this bank prepares you for, and that exam is listed as available.

Fortinet’s stated rule is that the previous version of an exam is generally last delivered four months after the new version is released, and its three 2026 version changes held to that within about half a month each. Our own projection is therefore that the FortiOS 7.6 exam stops being deliverable roughly four months after FortiOS 8.0 appears, which can fall inside an access term bought today. That is our projection from Fortinet’s published rule, not a date Fortinet has confirmed. Both pages are linked below; check them yourself.

So here is what your purchase covers: buy the NSE 4 exam once and you get every NSE 4 practice bank we publish while your access runs — the FortiOS 7.6 bank today, and a FortiOS 8.0 bank automatically as soon as it exists, at no extra charge and with no second purchase.

Fortinet’s own pages, so you can check this instead of believing us: Fortinet, NSE exam release notices: new and discontinued exams · Fortinet, NSE 4 FortiOS 7.6 Administrator exam description. Last checked 11 September 2026.

Buy this exam You sign in first, so your purchase attaches to your account and is there whenever you come back. Payment is taken by our merchant of record, who is the seller and handles tax; we never see your card details.

The guarantee, plainly. If you sit the NSE 4 FortiOS 7.6 Administrator exam during your access term and do not pass, send us the result notification the certification body gave you and we refund what you paid for this product. There is a 48-hour no-reason refund window on top of it. Conditions apply and both are written out on the refunds page — read them before you buy. This is a refund of our fee. It is not a prediction about your result, and we do not promise that you will pass.
