attached to a subnet, you need tocreate an ingress rule that allows stateful connections on port 3306 and 33060(Answer C).<br\/>* Ingress Rule: An ingress rule specifies the types of inbound connections that are allowed to a resource within a subnet.<br\/>* Stateful Connections: Stateful connections keep track of the state of network connections passing through them, allowing return traffic to pass automatically.<br\/>Steps:<br\/>* Navigate to the Virtual Cloud Network (VCN) in the OCI Console.<br\/>* Open the subnet to which the MySQL DB system is attached.<br\/>* Add an ingress rule to the subnet&#8217;s security list to allow traffic on port 3306 (MySQL) and 33060 (MySQL X Protocol).<br\/>* Ensure the rule is stateful to maintain the connection state.<br\/>References:<br\/>* OCI Networking Documentation<br\/>* MySQL X Protocol Documentation<\/div><input type='button' class='showchecked' style='margin: 10px 0;' onclick='showanswer1(13,this)'
