Which are two of the tasks that must be performed to enable SQL*NET access for your
DBaaS database instance over SSL?
A.
You must open a port on the virtual machine (VM) that is hosting the instance.
B.
You use Net Manager (NETMGR) to configure a database alias and set the connect
string.
C.
You use Oracle Connection Manager to configure the required network settings.
D.
You must configure SSL support on the instance.
Explanation:
SQL*Net is Oracle’s remote data access protocol that enables client-server and serverserver communications across networks.
An Oracle client connects to the server using the port address of the listener, which is
normally defined as TCP port 1521 during Oracle installation.
Oracle Net Manager is a utility used for configuring SQL*Net.

SQL Developer is a GUI tool that provides all the functionality of SQL*Plus and adds a high degree of ease of use.
SQL Developer in recent releases (4.1.x) has added several cloud-specific features. There are three ways to access your
deployment.
>> Open SQL*Net port(1521) on the compute node.
>> Create an SSH tunnel for port 1521.
>> Use the SQL Developer built in ability to create an SSH tunnel.

Using Oracle Net Manager to Configure Oracle Net Services
Oracle Net Manager enables you to configure Oracle Net Services for an Oracle home on a local client or server host.
Listeners: Create and configure listeners to receive client connections.
Naming: Define connect identifiers and map them to connect descriptors to identify the network location and identification of a service. Oracle Net Manager supports configuration of connect descriptors in local tnsnames.ora files or a centralized directory service.
Naming Methods: Configure the ways connect identifiers are resolved to connect descriptors.
Profiles: Configure preferences for enabling and configuring Oracle Net features on the client or server.
