You need to configure fine-grained access control to external network resources from within your
database. You create an access control list (ACL) using the DBMS_NETWORK_ACL_ADMIN
package.
Which statement is true regarding the ACL created?
A.
It is a list of remote database links stored in the XML file that are available to the users of the
database.
B.
It is a list of users and network privileges stored in the XML file according to which a group of
users canconnect to one or more hosts.
C.
It is a list of users and network privileges stored in the data dictionary according to which a
group of userscan connect to one or more hosts.
D.
It is the list of the host names or the IP addresses stored in the data dictionary that can connect
to yourdatabase through PL/SQL network utility packages such as UTL_TCP.
Explanation:
The DBMS_NETWORK_ACL_ADMIN package provides the interface to administer the network
Access ControlList (ACL).
Refer to here for About Fin-Grained Access to External Network ServicesConfiguring fine-grained
access control for users and roles that need to access external network services fromthe
database. This way, specific groups of users can connect to one or more host computers, based
onprivileges that you grant them. Typically, you use this feature to control access to applications
that run onspecific host addresses.
To configure fine-grained access control to external network services, you create an access
control list (ACL),which is stored in Oracle XML DB. You can create the access control list by
using Oracle XML DB itself, orby using the DBMS_NETWORK_ACL_ADMIN and
DBMS_NETWORK_ACL_UTILITY PL/SQL packages. This guideexplains how to use these
packages to create and manage the access control list. To create an access controllist by using
Oracle XML DB and for general conceptual information about access control lists, see Oracle
XMLDB Developer’s Guide.
