NAT HRP (Hot Standby High Reliability Protocol)is used in Huawei firewalls to synchronizeNAT sessions and state informationbetween theactive and standby firewalls. This enablesseamless failoverwithout session interruption, thereby improving thereliabilityof the firewall deployment.
A: VLANis used for logical segmentation
B: Securityis a broad concept, not a specific technology
C: Policiesgovern traffic handling but don't impact hardware reliability directly Reference:

According to Huawei's documentation on theiMaster NCE series, theiMaster NCE-IPis theonly controller that supports unified LAN and WAN management, providing centralized control, O&M, and intelligent policy enforcement across both LAN and WAN domains.
iMaster NCE-Fabric: Focuses on data center networks.
iMaster NCE-Campus: Primarily for campus LAN management.
iMaster NCE-WAN: Focuses only on WAN orchestration.
iMaster NCE-IP:Integrates LAN and WAN managementto offer end-to-end control.

HuaweiAirEngine APswith theleader AP featureare capable of managing Fit APs insmall-scale or branch networks. The supportedforwarding modesinclude:
A: Tunnel forwarding: Traffic is encapsulated and sent to the gateway (leader AP or AC) B: Direct forwarding: Traffic exits directly at the AP to reduce latency Bridge forwardingandroute forwardingare not standard forwarding modes in this context.Bridge modegenerally applies to Layer 2 switching, androute forwardingpertains to Layer 3 routers, not WLAN forwarding at the AP level.

Huawei'sNAC (Network Access Control)solution on campus networks supportsmultiple authentication modes, including:
A: 802.1X authentication: Uses credentials with a supplicant (e.g., on a PC or phone) C: Portal authentication: Redirects users to a login webpage D: MAC address authentication: Authenticates based on the device's MAC address, often used for IoT or non- interactive devices B: Wireless authenticationis not an authentication mode itself; rather, wireless clients can use802.1X or portalmethods over WLAN.
