Quick Answer
The answer is a geography object. This is the correct choice because a geography object leverages FortiOS’s integrated GeoIP database to dynamically match traffic based on a specific country, continent, or region, such as France, by resolving the IP ranges assigned by IANA and regional internet registries. On the Fortinet NSE 4 Network Security Professional exam, this concept tests your understanding of how to implement a firewall policy geographic location rule without manually listing IP addresses, which would be inefficient and prone to error. A common trap is confusing geography objects with IP address objects or FQDN objects—remember that only geography objects use the GeoIP database for country-based matching. For the exam, a useful memory tip is “Geo for GeoIP,” meaning if the policy needs to filter by geographic location, always choose the geography object type.
This NSE4 practice question tests your understanding of firewall policies and nat. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. 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.
An admin needs to create a firewall policy that matches traffic based on the destination being a specific geographic location (e.g., France). Which address object should be used?
A geography object
Geography objects use IP geolocation databases to match traffic from/to a country.
An FQDN object
Why wrong: FQDN matches by domain name, not geography.
A subnet object
Why wrong: Subnet matches specific IP ranges, not countries.
A wildcard FQDN object
Why wrong: Wildcard FQDN matches domain patterns, not geography.

Correct answer & explanation
A geography object
A geography object is specifically designed to match traffic based on geographic location (country, continent, or region) using the GeoIP database integrated into FortiOS. When a firewall policy needs to allow or deny traffic to or from a specific country like France, a geography object is the correct address object type because it dynamically resolves IP ranges assigned to that country by IANA/RIRs.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.
A geography object
Why this is correct
Geography objects use IP geolocation databases to match traffic from/to a country.
Related concept

An FQDN object
Why it's wrong here
FQDN matches by domain name, not geography.
A subnet object
Why it's wrong here
Subnet matches specific IP ranges, not countries.
A wildcard FQDN object
Why it's wrong here
Wildcard FQDN matches domain patterns, not geography.
Common exam traps
The trap here is that candidates may confuse geography objects with FQDN or wildcard FQDN objects, mistakenly thinking domain-based objects can represent geographic regions, when in fact only geography objects leverage the GeoIP database for location-based matching.
Detailed technical explanation
FortiOS uses a regularly updated GeoIP database (from MaxMind or FortiGuard) that maps IP prefixes to countries, regions, and continents. When a geography object is used in a firewall policy, the FortiGate inspects the source or destination IP address and performs a lookup against this database at the session level, not per packet, to minimize performance impact. This allows policies to enforce geo-blocking or geo-allowing without maintaining static IP lists that would become outdated as IP allocations change.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
A small business has 20 workstations on the 192.168.1.0/24 network and one public IP from its ISP. The router uses PAT (NAT overload) so all 20 devices share one public address using different source ports. NAT questions test whether you understand the four address terms and which direction each translation applies.
