Which of the following APs is not involved in the campus energy saving solution?
Answer(s): B
Huawei’s Intelligent Energy Saving Solution (Zero-bit, Zero-watt) uses AI to transition APs between states based on traffic demand. In this logic:Energy-saving APs (A): Are those identified by the system to enter a deep sleep/hibernation mode when traffic is low.Assurance APs (D): Remain active to provide basic signal coverage and "listen" for wake-up triggers.Leader APs (C): Function as the local controller (in small-scale deployments) to coordinate these states.IoT APs (B), while they support converged services, are not defined as a specific functional role within the energy-saving state-switching algorithm itself, as IoT devices often require persistent, low-power connectivity that differs from standard Wi-Fi user traffic patterns.
Which of the following information is contained in the DHCP snooping binding table?
Answer(s): A,B,C,D
DHCP Snooping is a key security feature in campus access layer design. When a client obtains an IP address, the switch populates a binding table that links the MAC address (B) and the assigned IP address (D) to the specific physical Interface (C) and the VLAN (A) ID. This table is then used by other security features like Dynamic ARP Inspection (DAI) and IP Source Guard (IPSG) to prevent spoofing attacks by verifying that incoming traffic matches the authorized entries in the binding table.
On a traditional network, network planning, configuration, and O&M are performed by professional network engineers. In contrast, on an SDN network, network services are abstracted, orchestrated, and automatically provisioned on demand through a centralized network control system.
Answer(s): A
This statement describes the fundamental shift from traditional networking to the SDN (Software-Defined Networking) model used in Huawei's Xinghe Intelligent Campus. By using iMaster NCE-Campus, the network complexity is hidden behind a GUI. Instead of manual, box-by-box configuration (CLI), services are defined as "intents" (e.g., "Guest Access" or "Production Fabric"), which the controller then automatically translates into configurations and deploys across the entire network fabric.
Which of the following is the main reason why SD-WAN requires high-specification devices?
Answer(s): D
While encryption (IPsec) is important, the "Intelligence" in SD-WAN comes from Application-based Routing. To perform Intelligent Traffic Steering, the gateway must identify traffic not just by IP/Port (L3/L4), but by the actual application (L7), such as distinguishing between Office 365 and YouTube.This requires DPI (Deep Packet Inspection) and complex signature matching, which is significantly more CPU and memory intensive than traditional destination-based routing, thus necessitating high-specification hardware.
Which of the following are the advantages of SDN?
The Huawei Xinghe Intelligent Campus leverages SDN to deliver four core benefits:Open Programmability (A): Via Northbound APIs for integration with 3rd-party apps.Network Automation (B): Automating full-lifecycle O&M.Rapid Service Provisioning (C): Reducing deployment time from weeks to minutes via templates.Network Virtualization (D): Using VXLAN/EVPN to create multiple isolated logical networks (e.g., IoT, Office, Security) on a single physical infrastructure.
