You are configuring network connections to your database instance.
What does each network group represent?
A.
It is used to allow unrestricted communication among some of your DBaaS instances
byusing a set of defined policies and access rules.
B.
It is used to define load balancing and failover configurations between RAC database
instances.
C.
It is used to define network connections to the Pluggable Databases (PDBs) within a
Container Database.
D.
It is used to manage the connections between your external application servers
(application servers that you currently use in your business environment) and your DBaaS
instances.
Explanation:
Network groups provide a method for VMs to be grouped together forcommunications and
firewall rules. You can define network groups to allow VMs within agroup to communicate
with each other, while also preventing those VMs fromcommunicating outside the group.
Note:
Access rule. Access rules define the permitted paths of communication for VMs that are
within a network group. You can define an access rule to enable a specific path of
communication between two network groups, or between a network groupand a specified
list of IP addresses.

A
To enable unrestricted communication among some of your DBCS database deployments (for example, to enable all the instances hosting your development environment to communicate with each other), you can create a network group and add all the DBCS database deployments to that network group. When you add a DBCS database deployment to a network group, the DBCS database deployment can communicate with all the other DBCS database deployments in the same
group.
