Quick Answer
The correct answer is the configuration under `config system snmp community` with `set query enable`, `set query-port 161`, and `set hosts 192.168.1.100`. This is correct because read-only SNMP monitoring on a FortiGate is achieved by enabling SNMP queries within a community, which allows the monitoring server to send GET requests for read-only data without needing to configure traps or global SNMP settings. On the Fortinet NSE 4 exam, this question tests your understanding of the specific hierarchy for SNMP read-only access, often tripping candidates who mistakenly enable SNMP globally under `config system snmp sysinfo` or who forget to restrict the host. A common trap is confusing the `set query enable` command with trap configuration, but remember: queries are for polling, traps are for alerts. For a quick memory tip, think “QUERY for QUERYing data” — if you need read-only polling, you enable queries, not traps.
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 wants to configure SNMP on a FortiGate to allow a monitoring server 192.168.1.100 to poll read-only information. Which set of commands is correct?

Correct answer & explanation
✓
config system snmp community edit 1 set name public set query enable set query-port 161 set hosts 192.168.1.100 end
Option B is correct because SNMP read-only polling on FortiGate is configured under the `config system snmp community` hierarchy. The `set query enable` command allows SNMP GET requests, `set query-port 161` specifies the standard SNMP port, and `set hosts 192.168.1.100` restricts polling to that specific monitoring server. This matches the requirement for read-only access without configuring traps or enabling SNMP globally via the sysinfo context.
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 the `config system snmp sysinfo` context (for system contact/location) with the community configuration context, or mistakenly think SNMP is enabled globally via a simple `set enable` command, when in fact the community must be explicitly created and enabled with `set query enable`.
Detailed technical explanation
How to think about this question
FortiGate SNMPv2c uses community strings as a form of authentication, and the `config system snmp community` block allows granular control over read-only (query) and read-write (notify) access. The `set hosts` command can specify individual IP addresses or subnets, and if omitted, the community is open to any source. In real-world deployments, restricting hosts is critical to prevent unauthorized SNMP queries that could expose system information like interface utilization, CPU load, and session counts.
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 practitioner preparing for the NSE4 exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.

FAQ
Questions learners often ask
What does this NSE4 question test?
System and Network Administration — This question tests System and Network Administration — Read the scenario before looking for a memorised answer..
What is the correct answer to this question?
The correct answer is: config system snmp community edit 1 set name public set query enable set query-port 161 set hosts 192.168.1.100 end — Option B is correct because SNMP read-only polling on FortiGate is configured under the `config system snmp community` hierarchy. The `set query enable` command allows SNMP GET requests, `set query-port 161` specifies the standard SNMP port, and `set hosts 192.168.1.100` restricts polling to that specific monitoring server. This matches the requirement for read-only access without configuring traps or enabling SNMP globally via the sysinfo context.

Same concept, more angles
1 more ways this is tested on NSE4
These questions test the same concept from different angles. Work through them to make sure you can recognise it however the exam phrases it.
Variation 1. A FortiGate administrator needs to allow SNMP monitoring from a management station at 10.10.10.50. Which TWO configuration steps are required? (Choose two.)
medium- ✓ A.Enable SNMP agent globally
- ✓ B.Configure an SNMP community with read-only access and restrict access to 10.10.10.50
- C.Configure an SNMP trap to send alerts to 10.10.10.50
- D.Enable SNMP on the interface connected to the management station
- E.Configure a firewall policy allowing SNMP from the management station
Why A: Option A is correct because the SNMP agent must be globally enabled on the FortiGate before any SNMP queries can be processed. Option B is correct because an SNMP community with read-only access defines the authentication and access control parameters, and restricting it to 10.10.10.50 ensures only that management station can poll the device.
