H19-404_V1.0 Exam Preparation Material | HCSE-Presales-Campus Network Planning and Design V1.0

Explanation:
The two IPsec encapsulation modes are transport mode and tunnel mode. In transport mode, IPsec protects the upper-layer payload of the original IP packet while retaining the original IP header as the packet’s outer header. It is commonly associated with end-to-end host communication, although it can also protect a GRE packet between tunnel endpoints.
In tunnel mode, IPsec protects the complete original IP packet and adds a new outer IP header containing the addresses of the IPsec peers. This mode is commonly used between security gateways, routers, or site-to-site VPN endpoints because the original source and destination information can be protected within the encrypted inner packet. RFC 4301 formally defines transport and tunnel as the two IPsec security-association modes.
AH and ESP are not encapsulation modes. They are IPsec security protocols. Authentication Header provides integrity and source authentication but not encryption. Encapsulating Security Payload can provide encryption, integrity, authentication, and anti-replay protection. Either protocol can conceptually operate in transport or tunnel mode, although ESP is overwhelmingly used for encrypted enterprise VPN and SD-WAN data channels.

Explanation:
After identifying a terminal, iMaster NCE-Campus can use the identification result for security monitoring, visibility, and policy automation. Spoofing detection is supported because the platform can compare a terminal’s current type and traffic behavior with its previously identified characteristics .
For example, if a device originally identified as an IP phone suddenly behaves like a PC, the system can generate a spoofing alarm or apply an isolation policy.
Terminal identification also supports statistics and reporting by vendor, operating system, device category, access port, and policy status. Huawei explicitly describes terminal-type statistics, report export, and visibility of access policies.
In addition, iMaster NCE-Campus can automatically deliver VLAN, security-group, QoS, authentication, and access-permission policies according to the identified terminal type.
Option B is incorrect because wired authentication is an admission process, not a service produced after terminal identification. Therefore, A, C, and D are correct.

Explanation:
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.

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.

Explanation:
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.
