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 'Permitted IP Addresses' under Device > Setup > Management.
Configuring 'Permitted IP Addresses' under Device > Setup > Management is the best security practice to restrict access to the firewall management interface. This setting allows only specified IP addresses or subnets to access the management interface, effectively creating an ACL. Option C is incorrect because interface management profiles are applied to dataplane interfaces, not the out-of-band management interface. Option B is incorrect because security policies do not apply to management plane traffic; they only control dataplane traffic. Option D is incorrect because 'Trusted Management Stations' is not a configuration option; the correct setting is 'Permitted IP Addresses' on the Management Access Settings page.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Configure 'Permitted IP Addresses' under Device > Setup > Management.
Why this is correct
This setting restricts management access to a predefined list of IP addresses.
- ✗
Create a security policy rule that blocks traffic to the management interface.
Why it's wrong here
Security policies only control dataplane traffic, not management plane traffic.
- ✗
Apply an interface management profile to the management interface.
Why it's wrong here
Management profiles are for dataplane interfaces to allow management protocols, but the management interface is always accessible; a profile cannot restrict source IPs.
- ✗
Enable 'Trusted Management Stations' under firewall settings.
Why it's wrong here
This is not a feature in PAN-OS; the correct feature is 'Permitted IP Addresses'.
