The correct answer is to configure Permitted IP Addresses under Device > Setup > Management. This setting creates a management-plane ACL that explicitly defines which source IPs can reach the firewall’s dedicated management interface, effectively restricting management interface access to only trusted hosts on the separate management network. On the PCNSA exam, this question tests your understanding of the separation between management-plane and dataplane traffic—a common trap is confusing interface management profiles (which control dataplane services like ping or HTTPS on production interfaces) with the management interface itself. Security policies do not apply to management traffic, and the “trusted management stations” option does not exist in the Palo Alto configuration. Remember the memory tip: “Permitted IPs protect the pilot—management profiles protect the passengers.” This directly reinforces that the management interface is locked down via its own dedicated ACL, not through dataplane rules.
PCNSA Core Concepts Practice Question
This PCNSA practice question tests your understanding of core concepts. 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 protect the firewall management interface from unauthorized access. The management interface is on a separate management network. Which of the following is the best security practice to restrict access?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "best"
Why it matters: Signals that multiple options may be partially correct. Choose the option that most directly solves the exact problem described, not the one that sounds most complete.
Configure 'Permitted IP Addresses' under Device > Setup > Management.
This setting restricts management access to a predefined list of IP addresses.
B
Create a security policy rule that blocks traffic to the management interface.
Why wrong: Security policies only control dataplane traffic, not management plane traffic.
C
Apply an interface management profile to the management interface.
Why wrong: Management profiles are for dataplane interfaces to allow management protocols, but the management interface is always accessible; a profile cannot restrict source IPs.
D
Enable 'Trusted Management Stations' under firewall settings.
Why wrong: This is not a feature in PAN-OS; the correct feature is 'Permitted IP Addresses'.
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.
Option B is correct. Creating an ACL on the management interface using the 'permitted IP addresses' setting is the standard method to restrict management access. Option A is wrong because interface management profiles are for dataplane interfaces, not the management interface itself. Option C is wrong because security policies do not apply to management traffic. Option D is wrong because the 'trusted management stations' option is not a configuration on the firewall.
Key principle: ACLs process entries top to bottom and stop at the first match. Entry order and interface direction matter as much as the permit or deny statement.

Common exam traps
Common exam trap: ACLs stop at the first match
ACLs are processed top to bottom. The first matching entry wins, and an implicit deny usually exists at the end.
Detailed technical explanation
How to think about this question
ACL questions test precision: source, destination, protocol, port and direction. A generally correct ACL can still fail if it is applied on the wrong interface or in the wrong direction.
KKey Concepts to Remember
Standard ACLs match source addresses.
Extended ACLs can match source, destination, protocol and ports.
The first matching ACL entry is used.
There is usually an implicit deny at the end.
TExam Day Tips
→Check inbound versus outbound direction.
→Read the ACL from top to bottom.
→Look for a broader permit or deny above the intended line.
Key takeaway
ACLs process entries top to bottom and stop at the first match. Entry order and interface direction matter as much as the permit or deny statement.
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.
What to study next
Got this wrong? Here's your next step.
Review ACL processing order, placement rules (standard near destination, extended near source), and inbound vs outbound direction. Study wildcard masks and implicit deny. Then practise related PCNSA ACL questions on filtering logic and placement.
