The correct answer is to create separate ZTNA rules for each application port, specifically for ports 8443 and 9090. This is required because a single ZTNA rule in FortiOS maps to exactly one proxy destination port; the rule configured with proxy destination 10.0.10.100:443 will only forward traffic destined for that specific port, dropping all other port connections. On the Fortinet NSE 7 Advanced Security NSE7 exam, this scenario tests your understanding that ZTNA rules operate on a per-port basis, not a per-IP basis, and the common trap is assuming a single rule can cover multiple ports behind a load balancer. A helpful memory tip is "one rule, one port" — think of each ZTNA rule as a dedicated tunnel for a single service port, so you must create a separate rule for each port you need to expose.
NSE7 Advanced VPN and Zero Trust Practice Question
This NSE7 practice question tests your understanding of advanced vpn and zero trust. Examine the command output carefully: the correct answer depends on what the output actually shows, not on general recall alone. 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 healthcare provider is deploying ZTNA to secure access to an internal electronic health records (EHR) system. The EHR system is composed of multiple web services running on different ports behind a load balancer with IP 10.0.10.100. The load balancer listens on ports 443, 8443, and 9090. The administrator configures a single ZTNA rule with proxy destination 10.0.10.100:443, expecting that the other ports will be accessed via the same rule. However, users report that they can only access the service on port 443; connections to ports 8443 and 9090 fail. The FortiGate logs show that requests to other ports are being dropped. What should the administrator do to resolve this?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Create separate ZTNA rules for each port (8443 and 9090).
Option C is correct because each ZTNA rule maps to a single proxy destination port. The rule configured with proxy destination 10.0.10.100:443 only forwards traffic for that specific port. To access services on ports 8443 and 9090, separate ZTNA rules must be created for each port, each with its own proxy destination and access proxy configuration.
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.
✗
Configure the load balancer to redirect all traffic to port 443.
Why it's wrong here
This would break the application functionality.
✗
Configure the ZTNA gateway to allow all ports to the load balancer.
Why it's wrong here
ZTNA rules must explicitly define the destination port.
✓
Create separate ZTNA rules for each port (8443 and 9090).
Why this is correct
ZTNA rules are port-specific.

✗
Ask users to change the port in their browser to 443.
Why it's wrong here
The application requires specific ports.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates assume a single ZTNA rule with a destination IP will automatically forward traffic to all ports on that IP, overlooking that ZTNA rules are port-specific and require separate rules for each service port.
Detailed technical explanation
How to think about this question
In FortiGate ZTNA, each access proxy rule defines a specific destination IP and port that the gateway will forward traffic to. The proxy destination is a tuple (IP:port) and the gateway performs port-based forwarding. If multiple ports are needed, each requires a separate rule or a wildcard port configuration (if supported by the proxy type), but standard HTTPS access proxies require explicit port definitions. This design enforces granular access control, preventing unintended port exposure.

TExam Day Tips
→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

Real-world example
How this comes up in practice
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.
