Huawei HCSE-Presales-Campus Network Planning and Design V1.0 Sample Questions (Q29-Q34):

NEW QUESTION # 29
What are the modes of the HSR RedBox?

Answer: A,B,C,D

Explanation:
An industrial RedBox can provide all four listed interconnection modes. In HSR-SAN mode, it connects a singly attached node that does not natively support High-availability Seamless Redundancy to an HSR network. The RedBox duplicates frames entering the HSR domain and removes duplicate frames before delivering traffic to the SAN.
HSR-PRP mode interconnects an HSR ring with a Parallel Redundancy Protocol network while preserving seamless redundancy. PRP-PRP mode couples two PRP network domains, while HSR-HSR mode connects separate HSR rings. Depending on the implementation, the HSR-HSR interconnection function may also be described as a QuadBox function because four HSR-facing ports can be involved.
The essential RedBox responsibilities are frame conversion, duplication, duplicate elimination, sequence- number handling, and prevention of unintended forwarding loops between redundancy domains. HSR and PRP use compatible duplicate-identification principles, enabling controlled interconnection between these network types without introducing a single point of failure. RedBoxes also provide redundant connectivity for devices that have only one ordinary Ethernet interface.


NEW QUESTION # 30
On which public clouds can vCPEs be deployed in SD-WAN scenarios?

Answer: A,B,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 # 31
An AP cannot work independently. Instead, it must be configured by a WAC or iMaster NCE-Campus.

Answer: A

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 # 32
Which of the following statements is true about MACsec?

Answer: D


NEW QUESTION # 33
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.
