Refer to exhibit. An engineer is troubleshooting tear down of control connections even though a valid CertificateSerialNumber is entered Which two actions resolve the issue? (Choose two)

The device's physical serial number must be correctly entered in vManage to match the WAN Edge's actual serial number, allowing the controller to recognize and onboard the specific device.

While duplicate IPs can cause connectivity issues, the problem specifies a valid certificate serial number is entered, implying the issue is with control plane identity or registration, not basic IP reachability.

Entering a valid product ID (model) on the PNP portal is essential for correct device identification and automated onboarding processes, which are critical for establishing stable control connections.

Matching the serial number file between controllers is related to controller-to-controller synchronization, not the initial control connection establishment of a single WAN Edge device.

If network reachability were entirely absent, the control connection would not initiate to tear down based on certificate serial number validation; the issue implies a deeper identity or registration problem.
