- A
Create a firewall policy to allow SNMP traffic from the monitoring server
Why wrong: SNMP access to the FortiGate itself is managed via trusted hosts or local-in policies, not firewall policies. However, if the monitoring server is on a different subnet, a policy might be needed for the traffic to reach the FortiGate? Actually, SNMP is management traffic, so it is subject to administrative access controls (trusted hosts). A separate firewall policy is not required for management traffic.
- B
Configure an SNMP community with read-only access
A community is required for authentication (v2c) and to define access.
- C
Enable the SNMP agent under System > SNMP
The SNMP agent must be enabled to allow queries.
- D
Set the SNMP trap destination IP
Why wrong: Traps are optional for monitoring; basic SNMP can work without traps.
- E
Configure a user for SNMPv3
Why wrong: SNMPv3 is not required; v2c is simpler and common.
Quick Answer
The correct choices are enabling the SNMP agent under System > SNMP and configuring an SNMP community with read-only access. These two steps are necessary for a basic SNMP setup on a FortiGate because the SNMP agent must be active to listen for and process incoming queries from a monitoring server, while a read-only community defines the authentication string and access permissions for SNMPv1/v2c, which are the most common versions used in basic monitoring scenarios. On the Fortinet NSE 4 Network Security Professional exam, this question tests your understanding of the minimum configuration required to allow external SNMP managers to poll the FortiGate for statistics; a common trap is thinking you need to configure SNMPv3 security or traps first, but those are optional enhancements, not part of the basic setup. A helpful memory tip is “Agent and Community” — think of the agent as the door that must be open, and the community as the password to walk through it.
NSE4 System and Network Administration Practice Question
This NSE4 practice question tests your understanding of system and network administration. 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.
An administrator is setting up SNMP monitoring on a FortiGate. Which two configurations are necessary for a basic SNMP setup? (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
Configure an SNMP community with read-only access
Option B is correct because an SNMP community with read-only access defines the basic authentication and access control for SNMPv1/v2c queries, which is essential for monitoring. Option C is correct because the SNMP agent must be enabled on the FortiGate to process SNMP requests from the monitoring server.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse optional features like trap destinations or SNMPv3 authentication as mandatory for basic monitoring, when only the agent enablement and a community string are required.
Detailed technical explanation
How to think about this question
SNMP monitoring relies on the SNMP agent (port 161/UDP) to respond to GET requests from a manager. The community string acts as a plaintext password in SNMPv1/v2c, and read-only access ensures the monitoring server can retrieve OIDs without modifying the device. Enabling the agent activates the SNMP daemon, which binds to the management interface and processes incoming requests.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
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
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
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.
