NEW QUESTION # 77
Devices that need to provide network services externally, such as WWW servers and FTP servers, can be placed in the DMZ.
- A. TRUE
- B. FALSE
Answer: A
Explanation:
This statement is TRUE . A DMZ is a special security zone used to place servers that must provide services to external users while still being isolated from the internal trusted network. Typical examples include WWW servers, FTP servers, mail servers, and DNS servers . These systems need to be accessible from outside networks such as the Internet, but placing them directly inside the internal network would increase security risk.
The purpose of the DMZ is to create a buffer area between the Untrust zone and the Trust zone. External users can be allowed to access the public-facing servers in the DMZ according to security policies, while access from the DMZ to the internal network can be more strictly restricted. This design helps reduce the chance that an attacker who compromises a public server can directly reach sensitive internal systems.
On Huawei firewalls, the DMZ is one of the default security zones and is specifically intended for such semi- public service devices. Therefore, devices that provide external network services, such as WWW and FTP servers, can correctly be deployed in the DMZ .

NEW QUESTION # 80
The traffic direction of a firewall is based on the zone priority. The _____ direction refers to the direction from a low-priority zone to a high-priority zone. Capitalize the first letter.
Answer:
Explanation:
Inbound
Explanation:
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 .
