• A.It is used to load data between Teradata and Oracle.
• B.It must be used by ETL developers to develop ODI processes.
• C.It can be used to embed ODI processes into another product.
• D.It enables developers to execute most ODI operations through a Java program.

Your customer wants a project in ODI, which contains a user function, to translate commands with different syntax for different technologies but with the same functionality.
How can you achieve this? (Choose the best answer.)

• A.The project must be explicitly mapped within an ODI mapping.
• B.A customize knowledge module is needed.
• C.It can be defined for every technology listed in the topology.
• D.An ODI procedure must be associated with it.

You must run the same mapping concurrently while avoiding clashes of ODI temporary objects. How must you implement this? (Choose the best answer.)

• A.Create a custom KM to handle this by using ODI variables defined at the Topology level to create unique temporary object names.
• B.Select the Use Unique Temporary Object Names check box at the Physical Design level.
• C.Use variables in the Logical Design of the Mapping to create unique temporary object names.
• D.Create a custom Knowledge Module (KM) to handle this by using ODI variables to create unique temporary object names.

Which two statements are true about big data support in ODI? (Choose two.)

• A.ODI performs data transformations inside a Hadoop cluster.
• B.ODI must perform data transformations outside Hadoop in an Oracle database.
• C.ODI uses its own transformation engine to process data in a Hadoop cluster.
• D.ODI allows moving data in and out of a Hadoop cluster.

You are designing a Mapping. How are target and source tables defined? (Choose the best answer.)

• A.Their definition is imported with a reverse-engineering process directly from databases and other sources.
• B.Their definition is imported with areverse-engineering process directly from databases and other sources, but you must manually define all keys and constraints existing on the database.
• C.Forevery load the definition of the tables used, their columns and constraints must be manually built.
• D.An external engine must be run to describe what metadata is needed for a Mapping.
