NEW QUESTION # 13
Which of the following statements is false about the energy-saving function of the digital map?
Answer: B
Explanation:
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.
NEW QUESTION # 14
An AP cannot work independently. Instead, it must be configured by a WAC or iMaster NCE-Campus.
Answer: B
Explanation:
The statement is false because "AP" is a generic term covering several operating architectures. A Fit AP requires a WAC, and a cloud-managed AP is centrally managed through iMaster NCE-Campus. However, a Fat AP is autonomous: it can operate and be configured independently without a centralized controller.
Huawei also describes the leader AP architecture, in which a capable AP integrates part of the WAC functionality, operates independently, and manages a limited number of Fit APs.
Therefore, the absolute claim that an AP cannot work independently is technically incorrect. The correct interpretation depends on the AP mode. Fit APs depend on a WAC or leader AP for centralized configuration and CAPWAP-based management, whereas Fat APs provide local control and forwarding. Huawei explicitly states that the Fat AP architecture is autonomous and requires no additional centralized control device.
Because at least one recognized AP architecture operates independently, the correct answer is False.
NEW QUESTION # 15
Which of the following statements is false about GRE over IPsec?
Answer: D
Explanation:
Option B is false because it reverses the encapsulation behavior. In IPsec transport mode, the IPsec security header is inserted after the existing IP header; a new outer IP header is not normally added. In tunnel mode, the complete original IP packet is encapsulated and a new outer IP header is added. Tunnel mode therefore generally introduces greater overhead and produces a longer packet than transport mode, not the reverse.
The remaining statements are correct. IPsec supports both transport and tunnel modes. GRE over IPsec performs GRE encapsulation first, allowing GRE to transport the original payload, and then applies IPsec protection to the resulting GRE packet. The IPsec security association is established between the GRE tunnel endpoints, protecting the GRE-encapsulated traffic as it traverses an untrusted transport network.
Huawei SD-WAN data channels can use either GRE or GRE over IPsec. GRE provides flexible overlay encapsulation, while IPsec adds confidentiality, integrity, origin authentication, and anti-replay protection for site-to-site traffic. Huawei specifically identifies IPsec encryption as the mechanism securing site-to-site SD- WAN services.
NEW QUESTION # 16
On which public clouds can vCPEs be deployed in SD-WAN scenarios?
Answer: A,C,D
Explanation:
In the product and course version covered by this examination, SD-WAN virtual CPEs can be deployed on AWS, Alibaba Cloud, and Microsoft Azure. A vCPE such as Huawei AR1000V provides SD-WAN routing functions as a virtual machine within a supported public-cloud infrastructure. It can connect enterprise branches to workloads hosted in the cloud and bring the cloud environment under the same controller-based management and policy-orchestration framework as physical CPEs.
This deployment provides one-hop cloud access, avoids unnecessarily routing cloud-bound traffic through a remote headquarters, and enables unified overlay networking between branches, data centers, and cloud virtual networks. Huawei states that the AR1000V virtual SD-WAN router can be deployed in public clouds to implement branch-to-cloud interconnection and unified policy orchestration. Huawei also describes flexible deployment of physical CPEs and vCPEs for cloud-access and PoP-based acceleration scenarios.
Huawei Cloud is not included in the supported public-cloud list represented by this specific H19-404 question. Product compatibility is version-dependent, so the correct examination answer is A, B, and C.
NEW QUESTION # 17
Traffic can be forwarded directly between the two PRP ports of a PRP RedBox.
Answer: B
Explanation:
The statement is false. In Parallel Redundancy Protocol, LAN A and LAN B must remain two separate, failure-independent networks. A PRP RedBox connects a singly attached node or conventional network to both parallel LANs and behaves toward the PRP network like a doubly attached node. It duplicates outgoing frames and transmits one copy through each PRP port. For incoming traffic, it accepts the first valid copy and discards the later duplicate before forwarding the frame through its interlink port.
The RedBox must not operate as a normal bridge that directly forwards frames from its LAN A port to its LAN B port. Doing so would connect the two redundant LANs, potentially creating loops, duplicate propagation, broadcast amplification, and a common failure path. That would defeat the fundamental PRP requirement that failure or disruption in one LAN must not affect the other.
The original video contains the typing error "PPR RedBox"; the correct term is PRP RedBox , meaning Parallel Redundancy Protocol Redundancy Box. PRP topology requires two separate networks with no direct links between them, while the RedBox provides controlled redundant attachment for non-PRP devices.
