Huawei H19-404_V1.0 Dumps Questions Answers

AR routers support registration query center–based deployment, email-based deployment, and DHCP Option 148–based deployment. In registration query center deployment, the router obtains basic network connectivity, resolves or contacts Huawei’s registration service, retrieves the address and port of iMaster NCE, and then initiates registration. Huawei identifies AR routers, firewalls, switches, and APs as applicable devices for this method.

Email-based deployment is a major SD-WAN ZTP method for AR routers operating as CPEs. An administrator creates the site and ZTP configuration on iMaster NCE and sends a deployment URL to the onsite engineer. After the URL is opened and the parameters are written to the router, the device connects to the WAN and automatically registers with the controller.

DHCP Option 148 can provide the controller’s southbound IP address and port number to an IPv4 AR router, enabling automatic registration. Barcode scanning through the CloudCampus APP is specifically presented as an AP onboarding method, not an AR-router deployment method. Therefore, A, C, and D are correct.

Option C is false. Traditional QoS can classify traffic and provide differentiated treatment for service categories such as voice, video, and ordinary data. It normally performs classification, marking, policing, shaping, congestion avoidance, and queue scheduling on an interface. This provides service-level differentiation but does not deliver sufficiently refined simultaneous management across multiple users and multiple applications.

Huawei’s material explicitly states that traditional QoS schedules traffic based on port bandwidth and can differentiate traffic according to service levels, but it is difficult to distinguish traffic by user. It also states that traditional QoS cannot manage and schedule traffic from multiple services and multiple users simultaneously.

HQoS addresses this limitation through hierarchical, multi-level queues. For example, a parent level can allocate bandwidth to departments, VPNs, sites, or users, while child queues prioritize applications such as voice, video, email, and best-effort traffic. Huawei describes HQoS as hierarchical scheduling that differentiates both services and users. Therefore, statements A, B, and D are correct, while statement C incorrectly attributes an HQoS capability to traditional QoS.

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

Professional security devices should be deployed at the headquarters or another centralized Internet-access site. Under centralized Internet access, branch Internet traffic is first carried through the SD-WAN overlay to the centralized gateway. The headquarters security infrastructure then performs access control and security inspection before forwarding the traffic to the Internet.

This approach is appropriate when branch CPEs lack sufficient processing capacity or advanced security functions. A centralized firewall or dedicated security platform can provide intrusion prevention, antivirus inspection, URL filtering, application control, content security, and unified logging. It also allows the enterprise to enforce one consistent security policy instead of maintaining separate advanced configurations at every branch.

Deploying advanced security capabilities on each CPE, as proposed in option C, is a distributed local-breakout design and does not satisfy the stated limitation concerning security-processing capability. Third-party cloud security services can be used in some site-to-cloud or secure Internet-access architectures, but they are not the intended headquarters-based centralized solution in this question.

Huawei explicitly states that centralized Internet traffic is diverted to the centralized access site and that the firewall function is deployed there to secure Internet services. Therefore, option D is correct.
