H19-338 Practice Exam Questions with Answers HCSP-Presales-Storage Certification

The leader AP does not establish a CAPWAP tunnel with the fit AP. The leader AP communicates with the fit AP through the management VLAN, and the fit AP establishes a CAPWAP tunnel with the AC. In tunnel forwarding mode, user traffic needs to pass through the leader AP. In direct forwarding mode, user traffic is directly transmitted from the AP egress rather than from the leader AP. In tunnel forwarding mode, the leader AP can manage more fit APs than in direct forwarding mode.

Free mobility is supported on a hybrid network consisting of Huawei and third-party devices, and the authentication point can be deployed on third-party devices. According to the Huawei CloudCampus Solution Description, free mobility is a feature that allows users to access network resources without changing their IP addresses or VLANs when they move within a virtual network (VN). Free mobility can be implemented on a hybrid network by using VXLAN tunneling technology and policy association.

The built-in LAN ports on all Huawei NetEngine AR6000/600 series routers can be used as WAN ports. According to the NetEngine AR6000 Series Enterprise Routers Product Overview, NetEngine AR6000/600 series routers support flexible WAN/LAN port configuration, which allows users to use any built-in LAN port as a WAN port.

 NE8000 X4 and X8 are high-end core routers designed for large-scale IP backbone networks, data centers, and metro networks . They support various redundancy designs to ensure high availability and reliability, such as MPU (Main Processing Unit) 1+1 backup, SFU (Switch Fabric Unit) 7+1 backup, and PEM (Power Entry Module) 1+1 backup . MPU 1+1 backup means that two MPUs work in active/standbymode and provide control plane redundancy . SFU 7+1 backup means that eight SFUs work in N+1 mode and provide data plane redundancy . PEM 1+1 backup means that two PEMs work in active/standby mode and provide power supply redundancy . The NE8000 X4 and X8 do not support power supply 9+1 backup, which is a feature of the NE8000 X16 router .

Spine nodes are core nodes on the fabric network, but they do need to support VXLAN in some scenarios. According to the Data Center Networking: What It Is, Why It Matters, And Types article, VXLAN is a tunnel encapsulation technology that allows overlay networks to be created on top of the underlay network. Spine nodes need to support VXLAN when they act as gateways between different overlay networks or between overlay and underlay networks.

Each AP does not need to be designed to cover as large an area as possible in order to provide better coverage in a high-density scenario. According to the Huawei AirEngine Wi-Fi 6 Solution White Paper, in a high-density scenario, each AP should be designed to cover a small area with high signal strength and low interference, which can improve user experience and network capacity.

NE8000 F1A has 36 1GE ports. According to the NetEngine 8000 F1A Service Router Datasheet3, NE8000 F1A supports flexible combinations of up to 56 ports, including 36 x GE, 16 x 10GE, 2 x 40GE, and 2 x 100GE ports.

iFIT is a technology that can provide real-time service quality visualization and minutes-level fault demarcation. It can collect and analyze network traffic data, identify network problems, and optimize network performance. iFIT uses Telemetry to collect data from network devices, and uses Network Cloud Engine (NCE) to process and display the data. iFIT can also use In-band Network Telemetry (INT) to embed data into packets for more accurate measurement.

HQoS (Hierarchical Quality of Service) is a technology that provides hierarchical per-user-per-service scheduling and quality guarantee for VIP users and high-priority services. HQoS can implement fine-grained traffic control and service differentiation based on user groups, service types, and service priorities. The control device and access device are not virtualized into one device by HQoS.

The WAN-side controller can manage only WAN services, not LAN services. The LAN-side controller can manage both LAN and WAN services. This is because the LAN-side controller supports both SD-WAN and SD-Campus functions, while the WAN-side controller only supports SD-WAN functions.

CloudEngine S5736-S supports iStack, which is a technology that allows multiple switches to be connected and managed as a single logical device, improving network scalability and reliability 1. The other features are not supported by the CloudEngine S5736-S. Native AC is a feature of the CloudEngine S7700 series switches that enables them to function as wireless access controllers 2. Free mobility is a feature of Huawei’s Agile Campus Network Solution that enables seamless roaming of wireless terminals 3. VXLAN is a technology that creates overlay networks to extend Layer 2 connectivity across Layer 3 networks 4, but it is not supported by the CloudEngine S5736-S 1.

NetEngineAR611W is a desktop router that is designed for small enterprises and SOHO enterprises. It integrates security and Wi-Fi functions, and its design is risk-free. NetEngineAR611W supports multiple WAN interfaces, such as ADSL2+, VDSL2, GE, and LTE. It also supports firewall, VPN, IPSec, NAT, and other security features. NetEngineAR611W can provide Wi-Fi coverage for up to 32 users.

CloudEngine S5732-H series multi-GE switches do not deliver a switching performance of 1760 Gbit/s. According to the CloudEngine S5732-H Series Multi-GE Switches Datasheet, CloudEngine S5732-H series multi-GE switches deliver a switching performance of up to 336 Gbit/s.
