- A
The FortiGate must be configured to log to both destinations simultaneously
Why wrong: This is a configuration step, not a condition. The conditions are the prerequisites for that configuration to be possible.
- B
The FortiGate must have a valid FortiCloud subscription
FortiCloud logging requires a valid subscription.
- C
The FortiGate must be in NAT mode
Why wrong: NAT mode is not a requirement for logging.
- D
The FortiGate must have a hard disk or SSD installed
Local disk logging requires physical storage. If the model does not have a disk, local logs cannot be stored.
- E
The FortiGate must have a policy to allow outbound traffic to FortiCloud
Why wrong: While connectivity is needed, a specific policy is not always required if the FortiGate has a default route; but it's often needed. However, the two primary conditions are subscription and disk.
NSE4 High Availability and Diagnostics Practice Question
This NSE4 practice question tests your understanding of high availability and diagnostics. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. 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 wants to send logs to both a local disk and a remote FortiCloud account. Which two conditions must be met for this to work? (Choose two.)
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
The FortiGate must have a valid FortiCloud subscription
The FortiGate must have local storage (disk) to store logs locally. It also must have connectivity to FortiCloud servers, and logging to FortiCloud must be enabled. The local disk logging is a separate configuration.
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.
- ✗
The FortiGate must be configured to log to both destinations simultaneously
Why it's wrong here
This is a configuration step, not a condition. The conditions are the prerequisites for that configuration to be possible.
- ✓
The FortiGate must have a valid FortiCloud subscription
Why this is correct
FortiCloud logging requires a valid subscription.
Related concept
Static NAT maps one inside address to one outside address.
- ✗
The FortiGate must be in NAT mode
Why it's wrong here
NAT mode is not a requirement for logging.
- ✓
The FortiGate must have a hard disk or SSD installed
Why this is correct
Local disk logging requires physical storage. If the model does not have a disk, local logs cannot be stored.
Related concept

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.
