How would you enable a port persistently to keep communication open through that port
always?

A.
To enable a port persistently, you must contact your DBaaS support team to update the
port specifications for use.

B.
You can use server certificates to map a server’s identity to enable persistent
connection through a port to DBaaS instances.

C.
All ports that are available in DBaaS servers must use an SSH tunnel and cannot be
enabled persistently.

D.
To enable a port persistently, you would require access to the Compute Cloud Service
Console to open the ports to a set of IP addresses.
