Huawei Updated H19-404_V1.0 Exam Questions and Answers by iqra

A terminal-type survey primarily determines the appropriate network admission control solution. Different terminal categories have different authentication capabilities and security requirements. Corporate laptops may support 802.1X authentication, guests may require Portal authentication, and printers, cameras, sensors, and other dumb terminals commonly require MAC-address authentication or automatic terminal identification.

Huawei recommends selecting authentication technologies according to the terminal type and usage scenario. For example, access switches can serve as authentication points for wired dumb terminals, while APs or other access devices can perform authentication for wireless users. After terminal identification is enabled, iMaster NCE-Campus can automatically assign VLANs, ACLs, security groups, QoS parameters, and other authorization policies according to terminal category.

The survey therefore establishes which endpoints support interactive authentication, which require non-interactive admission, and which must receive special isolation or compliance policies. It does not independently determine the complete physical network architecture or the overall O & M platform. Consequently, the terminal survey is used to formulate the network admission control solution, making option C correct.

==================

The AR5710-SE is the security-enhanced model that supports intrusion prevention, antivirus, and URL filtering concurrently. The “SE” variant is designed for branch scenarios requiring integrated routing and advanced security processing instead of only basic WAN connectivity and packet forwarding.

IPS examines network traffic for attack signatures and abnormal behavior and can block detected intrusions. Antivirus inspection identifies malicious files or content using security-signature databases. URL filtering controls access to websites based on categories, reputation, or explicitly configured allowlists and blocklists. Supporting all three functions simultaneously allows the AR5710-SE to operate as both an SD-WAN CPE and a secure branch egress gateway, reducing the requirement for an additional branch firewall.

Huawei’s SD-WAN security architecture identifies firewall protection, antivirus, IPS, and URL filtering as its principal service-traffic security functions. Huawei also recommends advanced security functions such as URL filtering, IPS, and antivirus for branch scenarios requiring stronger Internet-egress protection. Among the listed models, the AR5710-SE provides the combined feature set. Therefore, option A is correct.

==================

Option B is false because a station retains its original IP address during Layer 3 roaming. Preserving the IP address is essential for maintaining active application sessions when the station moves between APs associated with different service VLANs, Layer 2 domains, and gateways. Huawei’s training diagram shows the same station IP address before and after roaming, while the service VLAN changes.

When the STA initially accesses the WLAN, a Home AP or HAP is selected for it. After the STA roams to a Foreign AP, the new AP obtains the station information and establishes the required forwarding relationship with the HAP. In direct-forwarding implementations, the STA’s traffic is encapsulated and forwarded to the HAP, which preserves access through the original network and gateway.

Therefore, A and C accurately describe HAP-based Layer 3 roaming. Option D is also correct: the APs use the same SSID and authentication mode but different service VLANs. The station’s IP address does not change, so B is the false statement.

==================

Option C is false. The digital-map energy-saving function provides network-wide energy visibility, identifies periods of low wireless demand, and recommends appropriate energy-saving time windows. During an approved energy-saving period, selected wireless APs or radio resources can be placed into an energy-saving state after the system evaluates coverage, traffic, and capacity requirements.

Automatically powering off switches is not the intended function. Campus switches may carry essential wired services, provide uplinks for other network devices, and supply PoE power to APs, cameras, phones, sensors, and access-control systems. Automatically shutting down a complete switch could therefore interrupt many unrelated services and potentially disconnect downstream network segments.

Huawei identifies low-carbon and energy-saving operation as a characteristic of cloud campus networks and combines this objective with AI-based intelligent O & M and proactive optimization. Its intelligent O & M architecture analyzes AP load trends and performs predictive wireless-network optimization, providing the analytical foundation for selecting safe energy-saving periods and resources.

Therefore, A, B, and D describe supported digital-map energy-saving capabilities. Automatic switch power-off is the false statement, making C correct.
