NEW QUESTION # 322
To deploy a virtual campus network using iMaster NCE-Campus, the following steps are performed. From top to bottom, sort the steps in the order in which they occur during network deployment and management.
Answer:
Explanation:
Correct Order of Steps:
1##Network planning
2##Site design
3##Device management
4##Fabric management
5##VN (Virtual Network) management
6##Service deployment
Understanding the iMaster NCE-Campus Deployment Process
# iMaster NCE-Campus is Huawei's AI-driven network automation and management platform for campus networks.
# The deployment follows a structured sequence to ensure a fully operational network.
Detailed Explanation of Each Step:
#1##Network Planning(First Step)
Defines the overallnetwork architecture, topology, and business requirements.
DeterminesWAN, LAN, and WLAN coveragefor the campus.
EnsuresIP addressing, VLANs, and security policiesare planned.
#2##Site Design(Second Step)
Createssite layoutsand determinesdevice placement(switches, APs, routers).
Definespower, cabling, and uplink requirementsfor optimal connectivity.
#3##Device Management(Third Step)
Onboards network devices (e.g., switches, APs, firewalls) into iMaster NCE-Campus.
Configuresinitial settingssuch asIP addresses, interfaces, and SNMP settings.
Ensuresdevices are registered and reachablein the management platform.
#4##Fabric Management(Fourth Step)
EstablishesVXLAN-based network fabricforautomated Layer 2/3 connectivity.
ConfiguresEVPN/VXLAN overlays, VTEPs, and underlay routing.
#5##VN (Virtual Network) Management(Fifth Step)
Definesvirtual networks (VNs) for different departments, tenants, or services.
ConfiguresQoS, ACLs, and network segmentation policies.
#6##Service Deployment(Final Step)
Activatesnetwork services like DHCP, security policies, and application access.
Ensures thatend-user connectivity and application traffic policies are in place.
Why Is This the Correct Order?
#Each step builds upon the previous one, ensuring a smooth and structured deployment process.
#Service deployment comes last because it finalizes user access and application connectivity.
Real-World Application:
Enterprise Campus Networks:Deployssecure, scalable campus connectivity with AI-based automation.
University Campuses & Smart Cities:UsesSDN-driven network segmentation and automationto simplify operations.
