Huawei firewalls use security zones to group interfaces that share the same trust level and security policy requirements. In the default configuration, Huawei firewalls provide four built-in zones that cover the most common deployment scenarios.

Trust represents the internal network where users and servers are typically considered more reliable. Untrust represents external networks such as the Internet, where traffic is considered untrusted and usually requires stricter access control and security inspection. DMZ is designed for semi-public servers (for example, web or mail servers) that must be reachable from Untrust but should be isolated from the Trust network to reduce lateral movement risk if a DMZ host is compromised. Local is a special zone that represents the firewall device itself (management plane and control plane). Traffic destined to or originating from the firewall (such as management access, routing protocol packets, or local services) is associated with the Local zone and is controlled using dedicated policies.

Because these four zones are pre-defined and available by default, all listed options are correct.

On Huawei firewalls, traffic direction is determined according to the priority of security zones . When traffic moves from a low-priority zone to a high-priority zone , that direction is called Inbound . For example, traffic going from the Untrust zone to the Trust zone is considered inbound because Untrust has a lower security priority than Trust.

By contrast, traffic moving from a high-priority zone to a low-priority zone is called Outbound . A common example is internal users in the Trust zone accessing resources on the Internet in the Untrust zone. This zone-priority concept is important because firewall security policies, packet filtering behavior, and session control are all evaluated according to the source zone and destination zone.

Understanding inbound and outbound directions is essential when configuring interzone security policies. Administrators must know whether traffic is flowing from low to high priority or high to low priority in order to apply the correct permit, deny, NAT, and inspection rules. Since the question specifically asks for the direction from a low-priority zone to a high-priority zone, the correct answer is Inbound .
