Explanation

For LAN-side APs in small/medium campus networks, three auto-discovery or manual provisioning methods are supported by typical enterprise wireless controllers (such as Huawei's AC architecture).

Why A, B, and D are correct:

• A (Command line start): Administrators can manually specify the AC's IP address via CLI directly on the AP - reliable for small deployments where each AP can be touched individually.
• B (DHCP Option): DHCP Option 43 (or vendor-specific options like Option 148) delivers the AC's IP address to APs automatically during IP assignment - the most scalable and widely recommended zero-touch method.
• D (Registration inquiry center): APs can query a centralized registration/inquiry server (e.g., a cloud or DNS-based discovery service) to locate the controller - useful when APs are pre-registered and provisioned remotely.

Why C is wrong: Email is a messaging protocol with no role in network device provisioning or AP-to-controller discovery. It does not exist as a mechanism in any standard WLAN deployment workflow.

Memory tip: Think of the three valid methods as Manual, Automatic, and Centralized - CLI (manual touch), DHCP Option (automatic on boot), and Registration Center (centralized lookup). Email belongs in your inbox, not your network config.
