The answer is to execute 'config system interface', edit wan1, and set allowaccess ping https ssh snmp. This is correct because the allowaccess parameter under config system interface explicitly controls which management protocols—such as ping, HTTPS, SSH, and SNMP—are permitted on a specific FortiGate interface, and adding snmp to that list enables SNMP access without altering the interface’s role or type. On the Fortinet NSE 4 Network Security Professional NSE4 exam, this tests your understanding of interface-level access control, a common configuration task that often appears in multiple-choice or CLI-based scenarios; a frequent trap is confusing this with global SNMP settings or assuming a separate SNMP interface is required. Remember the mnemonic “P-H-S-S” for the typical allowaccess order (ping, HTTPS, SSH, SNMP) to quickly recall which protocols are managed per interface.
NSE4 System and Network Administration Practice Question
This NSE4 practice question tests your understanding of system and network administration. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. 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.
Exhibit
config system interface
edit "wan1"
set vdom "root"
set ip 10.0.0.1 255.255.255.0
set allowaccess ping https ssh
set type wan
set role wan
set snmp-index 1
next
end
Refer to the exhibit. An administrator wants to enable SNMP access on the wan1 interface. Which of the following is the most efficient method?
config system interface
edit "wan1"
set vdom "root"
set ip 10.0.0.1 255.255.255.0
set allowaccess ping https ssh
set type wan
set role wan
set snmp-index 1
next
end
A
Execute 'config system interface' and edit wan1, then set allowaccess ping https ssh snmp.
Adding 'snmp' to allowaccess enables SNMP on that interface.
B
Change the interface type to 'management' to allow SNMP.
Why wrong: Changing type does not enable SNMP access.
C
Execute 'config system interface' and edit wan1, then set snmp-index 1.
Why wrong: snmp-index already exists; it does not enable SNMP access.
D
Configure an SNMP community under 'config system snmp community'.
Why wrong: Community is needed but not sufficient; interface must allow snmp.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Execute 'config system interface' and edit wan1, then set allowaccess ping https ssh snmp.
Option A is correct because the 'allowaccess' parameter under 'config system interface' controls which management protocols (ping, https, ssh, snmp, etc.) are permitted on a given interface. By adding 'snmp' to the allowaccess list for wan1, the administrator enables SNMP access on that interface without changing its role or type.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis

Execute 'config system interface' and edit wan1, then set snmp-index 1.
Why it's wrong here

Why it's wrong here
Community is needed but not sufficient; interface must allow snmp.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse configuring an SNMP community (which defines who can query) with enabling SNMP access on an interface (which allows the SNMP agent to listen on that interface); both are required, but the question asks for the most efficient method to enable SNMP access on wan1, which is setting 'allowaccess snmp' on that interface.
Detailed technical explanation
How to think about this question
The 'allowaccess' setting controls which management daemons (e.g., HTTPS, SSH, SNMP, Ping, TELNET) listen on that interface's IP address. Without 'snmp' in the allowaccess list, the SNMP agent will not respond on that interface even if a valid community is configured. This is a common source of troubleshooting issues when SNMP queries fail despite correct community settings.

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 security administrator must allow nursing staff to reach a patient records server while blocking access from the guest Wi-Fi VLAN. After applying an extended ACL, traffic is still blocked from nursing workstations. The ACL was applied outbound instead of inbound on the wrong interface. Questions like this test ACL direction and placement rules.
