The correct answer is to enable remote logging under Log Settings and specify the FortiAnalyzer IP address. This configuration works because the FortiGate sends traffic logs directly to the FortiAnalyzer over the network, bypassing the local disk entirely; a full local disk does not interrupt or delay this outbound log stream. On the Fortinet NSE 4 Network Security Professional exam, this scenario tests your understanding of log destinations and the independence of remote logging from local storage constraints. A common trap is assuming you must first free local disk space or enable a “fallback” mode, but the direct method is simply configuring the FortiAnalyzer as a remote log server. Remember the key concept: remote logging is not affected by local disk fullness, so you only need to point the FortiGate to the FortiAnalyzer. Memory tip: “Remote logs ride the network, not the disk.”
NSE4 High Availability and Diagnostics Practice Question
This NSE4 practice question tests your understanding of high availability and diagnostics. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. 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 needs to ensure that traffic logs are sent to a FortiAnalyzer even when the FortiGate's local disk is full. What configuration is required?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Enable 'remote log' under Log Settings and specify the FortiAnalyzer IP
Configuring the FortiAnalyzer as a log destination ensures logs are sent immediately. The local disk issue does not affect remote logging. Optionally, the admin can set logging to 'fallback' or 'any', but the direct method is to configure the remote syslog/FortiAnalyzer.
Key principle: NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
Enable 'disk logging' with rollover policy
Why it's wrong here
Disk logging is local; if disk is full, logs may be lost.
✗
Increase the log severity to 'emergency' only
Why it's wrong here
This reduces log volume but does not send logs to FortiAnalyzer.
✓
Enable 'remote log' under Log Settings and specify the FortiAnalyzer IP
Why this is correct
This directly sends logs to FortiAnalyzer, independent of local disk.
Related concept
Static NAT maps one inside address to one outside address.
✗
Configure a log filter to send only security logs
Why it's wrong here
Filtering does not change the destination.
Common exam traps
Common exam trap: NAT rules depend on direction and matching traffic
NAT is not only about the public address. The inside/outside interface roles and the ACL or rule that matches traffic are just as important.
Detailed technical explanation
How to think about this question
NAT questions usually test address translation, overload/PAT behaviour, static mappings and whether the right traffic is being translated. Read the interface direction and address terms carefully.
KKey Concepts to Remember
Static NAT maps one inside address to one outside address.
PAT allows many inside hosts to share one public address using ports.
Inside local and inside global describe the private and translated addresses.
NAT ACLs identify traffic for translation, not always security filtering.
TExam Day Tips
→Identify inside and outside interfaces first.
→Check whether the scenario needs static NAT, dynamic NAT or PAT.
→Do not confuse NAT matching ACLs with normal packet-filtering intent.
Key takeaway
NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.
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.
What to study next
Got this wrong? Here's your next step.
Review the four NAT address types (inside local, inside global, outside local, outside global), PAT port overload, and static vs dynamic NAT use cases. Then practise related NSE4 NAT questions on configuration and troubleshooting.

Variation 1. A FortiGate administrator needs to send logs to a FortiAnalyzer device for long-term storage and analysis. Which log configuration must be set up?
medium
A.Configure an IPsec tunnel to FortiAnalyzer
✓ B.Add the FortiAnalyzer as a logging destination in Log Settings
C.Enable disk logging on the FortiGate
D.Configure syslog server pointing to FortiAnalyzer IP
Why B: Logs are sent to FortiAnalyzer by configuring the Log Settings > Log Forwarding or the Log & Report > Log Setting to send logs to FortiAnalyzer.
