Your customer has two CDBs: one for Production and one for development. You are asked to create a new development PDB (salesdev) from an existing production PDB (salesprd). Which two options would accomplish this? 

Answer options:

A. You copy all the PDBSSEEDdata files from the production CDB into the development CDB and execute this on the development CDB;SQL> CREATE PLUGGABLE DATABASE salesdev ADMIN USER salesdm IDENTIFIED by password;
B. You alter the salesprd source database to open in read-only mode, and start cloning the source database:SQL> ALTER PLUGGABLE DATABASE salesprd OPEN READ ONLY;SQL> CREATE PLUGGABLE DATABASE salesdev FROM salesprd;
C. You alter the salesprd source database to open in read-only mode:SQL> ALTER PLUGGABLE DATABASE salesprd OPEN READ ONLY;In the development CDB, you create a databaselink "PRD" that connects to the root of the source CDB, and start cloning the source PDB:SQL> CREATE PLUGGABLE DATABASE salesdevFROM salesprd@prd;
D. Connected as the salesprd local DBA, you create an XML using:SQL> ALTER PLUGGABLE DATABASE salespdb UNPLUG INTO ` /tmp/salesprd-xml` ;Copy the XML file and all salesprd-related files to the target CDB and start plugging the copy into the development CDB using:SQL> CREATE PLUGGABLE

A: Creating a PDB Using the Seed You can use the CREATE PLUGGABLE DATABASE statement to create a PDB in a CDB using the files of the seed. D: Plugging In an Unplugged PDB - To plug in an unplugged PDB, the following prerequisites must be met: * Complete the prerequisites described in "Preparing for PDBs". * The XML file that describes the PDB must exist in a location that is accessible to the CDB. The USING clause must specify the XML file. Etc
