Oracle 1z0-915-1 Dumps Questions Answers

To connect to a MySQL DB system from an OCI Cloud Shell session when the VCN is not configured with VCN peering, VPN access, or FastConnect, the following must be true:

A.You must attach the Cloud Shell session to a VCN subnet that can connect to the MySQL DB system: The Cloud Shell must be in the same network or have a route to the network containing the MySQL DB system. C.The MySQL DB system subnet must be in theCloud Shell tenancy home region: Cloud Shell sessions operate within the OCI home region, so the target MySQL DB system must be accessible from within the same region.

To enable client applications to connect to a MySQL DB system that uses default port numbers and is attached to a subnet, you need tocreate an ingress rule that allows stateful connections on port 3306 and 33060(Answer C).

Ingress Rule: An ingress rule specifies the types of inbound connections that are allowed to a resource within a subnet.

Stateful Connections: Stateful connections keep track of the state of network connections passing through them, allowing return traffic to pass automatically.

Steps:

Navigate to the Virtual Cloud Network (VCN) in the OCI Console.

Open the subnet to which the MySQL DB system is attached.

Add an ingress rule to the subnet's security list to allow traffic on port 3306 (MySQL) and 33060 (MySQL X Protocol).

Ensure the rule is stateful to maintain the connection state.

In MySQL HeatWave configurations, dynamic variables can be changed without requiring the configuration to be copied to a new configuration. This allows for more flexible and immediate adjustments to system settings without the need for a server restart or creating a new configuration instance.
