Refer to the exhibit vManage and vBond have an issue establishing a connection to vSmart...

To resolve this issue and allow the vSmart to establish a connection, the administrator must complete the certificate installation process. The correct two actions are:

E. Request a certificate from the certificate server based on the CSR for the vSmart. The generated CSR must be sent to a Certificate Authority (CA), which will then sign it and issue a valid digital certificate.

A. Install the certificate received from the certificate server. Once the signed certificate is received from the CA, the administrator must upload and install it in vManage for the vSmart controller. After the certificate is successfully installed, the "Operation Status" will change, and the vSmart will be able to join the SD-WAN fabric.
