You created your Database as a Service (DBaaS) database instance. Predefined network access rules are also created.
Which two predefined network access rules are created when you created the DBaaS database instance?
A.
The ora_p2_ssh access rule for the public-internet network group is created to communicate with the ora_db predefined network group over SSH.
B.
The ora_db_public access rules to manage database access through the default port 1521 and the ora_db_admin access rules for SSH connection via
SQL*Net through port 5500 are created.
C.
The ora_access db access rule for SSH connection via PuTTY is created to configure network rules and ora_access_console for HTTPS access to Oracle
Cloud Services Console.
D.
No access rules are created by default and users must manually configure all access rules.
E.
The ora_p2_dblistener access rule for the public-internet network group (any host on the Internet) is created to communicate with the ora_db predefined
network group over SQL*Net.
Explanation:
When a database deployment is created, the following Oracle Compute Cloud Service security rules are created, but set to a disabled status.
ora_p2_dbconsole, which controls access to port 1158, the port used by Enterprise Manager 11g Database Control.
ora_p2_dbexpress, which controls access to port 5500, the port used by Enterprise Manager Database Express 12c.
ora_p2_dblistener, which controls access to the port used by SQL*Net.
ora_p2_http, which controls access to port 80, the port used for HTTP connections.
ora_p2_httpssl, which controls access to port 443, the port used for HTTPS connections, including Oracle REST Data Services, Oracle Application Express, and
Oracle DBaaS Monitor.
