An engineer is migrating to a new Cisco Catalyst CW9800-H1 WLC to modernize the wireless infrastructure and enable advanced monitoring capabilities. The organization operates more than
150 access points and uses Cisco Catalyst Center for centralized network management and assurance. As part of the deployment, the engineer must enable wireless service assurance and wireless telemetry to monitor client connectivity, roaming behavior, and performance metrics across the wireless network. Which configuration must be applied in Cisco Catalyst Center when onboarding the WLC?

• A.Configure CLI and SNMP credentials and the NETCONF port during device discovery and ensure that device controllability is enabled under device settings. When discovered, assign the WLC and APs to a site with wireless telemetry enabled.
• B.Configure CLI and SNMP credentials and the NETCONF port during device discovery and ensure that wireless telemetry is enabled under system settings. When discovered, assign the WLC to a site with device controllability enabled.
• C.Enable CLI, SNMP, and NETCONF credentials during device discovery and ensure that wireless assurance is enabled globally. When discovered, assign the WLC to a site with device controllability enabled.
• D.Enable CLI, SNMP, and NETCONF credentials during device discovery and ensure that device controllability is enabled globally. When discovered, assign the WLC to a site with wireless assurance enabled.
