H19-401_V1.0 Sample Questions Answers

Huawei’s free mobility solution enhances user authentication and access control by synchronizing IP-security group entries across devices, ensuring seamless policy enforcement. The HCSP-Presales-Campus Network Planning and Design V1.0 documentation specifies:

Switches: Campus switches (e.g., CloudEngine series) can act as access devices, authenticating terminals via methods like 802.1X or MAC authentication. They support IP-security group synchronization to enforce consistent policies.

APs (Access Points): Wireless APs (e.g., AirEngine series) serve as access devices in WLAN scenarios, authenticating terminals via 802.1X, portal, or MAC methods. They also participate in IP-security group synchronization for mobility.

AR (Access Routers): While AR routers (e.g., NetEngine AR series) can perform authentication in certain contexts, they are typically not access devices in the free mobility solution’s context, focusing instead on routing and WAN functions.

Huawei’s SD-WAN solution comprises specific components. The HCSP-Presales-Campus Network Planning and Design V1.0 documentation highlights:

C: iMaster NCE is the management and control platform.

E: CPE (Customer Premises Equipment) is the edge device for connectivity.

A (NE): Network Element is a generic term, not a specific SD-WAN component.

B (Gateway): Used in some contexts but not a key SD-WAN component.

Huawei’s SD-WAN architecture is multi-layered. The HCSP-Presales-Campus Network Planning and Design V1.0 documentation defines:

A: Control layer (e.g., RR) manages routing and overlay topology.

B: Network layer (e.g., CPEs) handles data transmission.

C: Management layer (e.g., iMaster NCE) oversees configuration and monitoring.

Clustering algorithms in CampusInsight identify connectivity patterns. The HCSP-Presales-Campus Network Planning and Design V1.0 documentation specifies:

A, B: SSID and vendor are used to group devices and analyze issues.

Data channels in Huawei’s SD-WAN solution carry overlay traffic. The HCSP-Presales-Campus Network Planning and Design V1.0 documentation clarifies:

Data channels primarily use IPsec (for security) or VxLAN (for flexibility), not GRE or GRE over IPsec as the default.

Wi-Fi 6 leverages Orthogonal Frequency Division Multiple Access (OFDMA) and Multi-User Multiple-Input Multiple-Output (MU-MIMO) to enhance multi-user performance. The HCSP-Presales-Campus Network Planning and Design V1.0 documentation clarifies their roles:

OFDMA: Divides frequency resources into smaller subcarriers (resource units), allowing multiple users to transmit simultaneously. It excels in small-packet transmission scenarios (e.g., IoT devices, VoIP) due to its ability to efficiently allocate bandwidth for low-data-rate streams.

Traffic steering optimizes SD-WAN. The HCSP-Presales-Campus Network Planning and Design V1.0 documentation lists:

Network Access Control (NAC) is a critical security framework for managing endpoint access to a network. The HCSP-Presales-Campus Network Planning and Design V1.0 documentation outlines various NAC methods and their characteristics:

A. MAC Address Authentication: This method relies on the unique MAC address of a device for authentication. In most cases, it requires administrators to manually register MAC addresses in adatabase (e.g., on a RADIUS server), which increases management complexity, especially in large or dynamic networks. This statement is true.

B. 802.1X Authentication Requirements: Contrary to the statement, 802.1X authentication typically has high requirements for client software, as it requires a supplicant (e.g., a compatible client supporting EAP) to be installed and configured on user terminals. This limits its flexibility in environments with diverse or unmanaged devices, making the statement false.

C. 802.1X Authentication Applicability: 802.1X is ideal for newly deployed networks with centralized user bases (e.g., enterprise campuses) and stringent security needs, as it enforces strong authentication (e.g., via EAP-TLS). This aligns with its use in controlled, high-security environments, making the statement true.

CloudCampus supports dual modes. The HCSP-Presales-Campus Network Planning and Design V1.0 documentation clarifies:

Indoor AP installation modes vary. The HCSP-Presales-Campus Network Planning and Design V1.0 documentation lists:

A, B, C: Threaded rod, ceiling, and wall mounting are standard for Huawei APs.

Huawei's free mobility solution is designed to provide seamless user access and authentication across a campus network, often integrating with Network Access Control (NAC) mechanisms like 802.1X, MAC authentication, or portal authentication. The HCSP-Presales-Campus Network Planning and Design V1.0 documentation specifies that the free mobility solution supports interoperability between Huawei devices and third-party devices within the same network.

Third-party devices, such as switches or access points, can function as end-user authentication points (e.g., 802.1X authenticators) as long as they comply with standard protocols like RADIUS or EAP. Huawei’s solution leverages open standards to ensure compatibility, allowing third-party devices to participate in authentication workflows.

AP coverage control is key in WLAN design. The HCSP-Presales-Campus Network Planning and Design V1.0 documentation specifies:

A, C: Antenna angle and transmit power directly adjust coverage area.

Scenario-based planning is systematic. The HCSP-Presales-Campus Network Planning and Design V1.0 documentation lists:

Network Access Control (NAC) involves multiple roles to enforce security policies. The HCSP-Presales-Campus Network Planning and Design V1.0 documentation defines these roles as:

Admission Device: This is the network device (e.g., switch or AP) that enforces access control policies and initiates authentication (e.g., as an 802.1X authenticator). It is a key NAC component.

User Terminal: The endpoint device (e.g., laptop, smartphone) requesting network access. It interacts with the admission device and often runs a supplicant for authentication.

User: While the user is the human entity accessing the network, NAC terminology focuses on technical components (devices and servers) rather than the user as a "role" in the process.

FireHunter is Huawei’s APT detection system, integrated into campus and SD-WAN solutions. The HCSP-Presales-Campus Network Planning and Design V1.0 documentation confirms:

It uses sandboxing with multi-engine virtualized detection to analyze static (code) and dynamic (runtime) software behavior.
