How many terminal identification methods are supported by Huawei's campus network solution?
Answer(s): A
Huawei’s terminal identification system (used in iMaster NCE-Campus for fingerprinting IoT devices) officially utilizes 7 distinct methods to ensure high accuracy:MAC OUI: Identification by the vendor prefix of the MAC address.HTTP User-Agent: Extracting device info from browser headers.DHCP Option: Identifying devices based on DHCP request parameters (e.g., Option 55/60).LLDP: Using Link Layer Discovery Protocol info.mDNS: Identifying Apple and other smart devices via multicast DNS.SNMP Query: Actively reading MIBs from terminals.Nmap/Proactive Scanning: Actively probing open ports and OS fingerprints.
How many 400GE ports can be supported by a single board on the next-generation flagship core switch CloudEngine S16700?
Answer(s): B
The CloudEngine S16700 is Huawei's flagship core switch for large-scale enterprise campuses. It features an orthogonal Clos architecture with massive per-slot bandwidth (up to 14.4 Tbps). To support the evolution to ultra-high-speed backbones, the S16700 supports a high-density 400GE line card that provides 18 ports per board. When fully populated (8 slots), the S16700-8 chassis can support up to 144x400GE ports.
Which of the following user access authentication modes are supported?
Answer(s): A,B,C
Huawei's Xinghe Intelligent Campus defines three standard "Access Authentication" modes for users and terminals:802.1X (B): High security, suitable for PCs and mobile devices with clients.Portal (C): Common for guest access and public areas (web-based login).MAC Address Authentication (A): Used primarily for "dumb" terminals like printers, cameras, and IoT devices that cannot perform 802.1X/Portal logins.OSPF Authentication (D) is a protocol-level security feature used to secure routing updates between routers, not an access authentication method for end-user devices.
Which of the following deployment modes are supported by APs?
Answer(s): A,C,D
In the Xinghe Intelligent Campus solution, APs (Access Points) support several automated "Plug-and-Play" deployment methods. Option A (Registration Query Center) allows an AP to query a Huawei-hosted global database to find its assigned controller. Option C (Barcode Scanning) uses the mobile app to scan the SN (Serial Number), binding the device to a site. Option D (DHCP Option 148) allows a local DHCP server to deliver the management IP of iMaster NCE-Campus directly to the AP. Email-based deployment (B) is reserved specifically for AR routers/CPEs in SD-WAN scenarios and is not a supported method for AP onboarding.
A virtual network is also called an overlay network. SD-WAN uses the IP overlay virtualization technology to build one or more virtual networks on top of physical networks. Service policies are deployed on virtual networks and decoupled from physical networks, thereby separating services from the WAN.
The core philosophy of SD-WAN within the Huawei campus architecture is the decoupling of the Underlay (the physical transport network like MPLS, Internet, or 5G) from the Overlay (the virtualized service network). By using IPsec or VXLAN tunnels, SD-WAN creates a logical network where business policies—such as application-based routing and security rules—are applied. This allows enterprises to change their service logic without modifying the underlying physical WAN infrastructure.
