Palo Alto Networks Certified Network Security Administrator (PCNSA)Palo Alto Networks Security PlatformMedium
A network security administrator needs to configure a Palo Alto Networks firewall to allow management access from a specific subnet, 192.168.10.0/24, using SSH and HTTPS. The firewall is in Layer 3 mode. Which interface type is typically used for out-of-band management access, and what configuration element is essential to restrict access to the specified subnet?
- AVirtual Wire Port; Security Zone
- BManagement Port; Interface Management Profile
- CService Route; Static Route
- DData Port; Security Policy
Show answer & explanationAnswer & explanation
Correct answer: B. Management Port; Interface Management Profile
The dedicated Management port (MGT interface) is typically used for out-of-band management. An Interface Management Profile is then applied to restrict access to specific services (SSH, HTTPS) and source IP addresses (192.168.10.0/24).
Why the other options are wrong
- A. Virtual Wire ports are for transparent inspection, not direct management, and security zones are for data plane segmentation.
- C. Service Routes define how the firewall itself reaches external services, and static routes are for data plane routing, not direct management access control.
- D. Data ports are for forwarding network traffic, not typically for dedicated out-of-band management, and security policies are for data plane traffic.
Management Interface & Profile
The Management (MGT) interface on a Palo Alto Networks firewall is a dedicated out-of-band port for administrative access. An Interface Management Profile defines which services (e.g., SSH, HTTPS) and source IP addresses are allowed to connect to this interface.
- Dedicated MGT port for out-of-band access
- Interface Management Profile controls access to the MGT interface
- Allows specifying permitted services (SSH, HTTPS, ping)
- Allows specifying permitted source IP addresses/subnets
Memory trick: Manage the 'MGT' port with a 'Profile' of who can enter.
