Q21. Which two statements are true about big data support in ODI?(Choose two.)
A. ODI uses its own transformation engine to process data in a Hadoop cluster.
B. ODI performs data transformations inside a Hadoop cluster.
C. ODI must perform data transformations outside Hadoop in an Oracle database.
D. ODI allows moving data in and out of a Hadoop cluster.
Q22. Which product is included in ODI web-based components?(Choose the best answer.)
A. Oracle BPEL Process Manager
B. Oracle GoldenGate
C. ODI Console
D. Oracle WebLogic Server
Q23. You are defining a data store in ODI metadata and want toadd a primary key even if it does not physically exist on the related database catalog.
How can you accomplish this?(Choose the best answer.)
A. You can add a primary key even if it does not physically exist on the related database catalog, by adding constraintson the data store.
B. You can add a primary key even if it does not physically exist on the related database catalog, by adding constraints to the data store diagram.
C. You cannot add a primary key if it does not physically exist on the related database catalog. You can flag only non-null conditions to be checked.
D. You cannot add a primary key if it does not physically exist on therelated database catalog. You can reverse engineer only the existing constraints.
Q24. Which statement is true about theIKM SQL Control Append thatcreates an intermediate integration table prefixed with I$?(Choose the best answer.)
A. Theintermediate integration table prefixed with I$is required to determine which records must be inserted.
B. IfFlow Control is not necessary, an I$ table is not created.
C. Theintermediate integration table prefixed with I$ is createdbecause the flow control is mandatory when doing an initial load.
D. Neither the LKM northe IKM create intermediate tables. Most of their work is performed in the ODI Agent memory.
Q25. The source and target data stores are located on the same data server. Which statement is correct about the need for a Loading KnowledgeModule to load the data on the target?(Choose the best answer.)
A. Only an Integration KnowledgeModule single-technology is required.
B. Only an Integration Knowledge Module multitechnology is required.
C. Aloading Knowledge Module multitechnology and an IntegrationKnowledgeModule single-technology are required.

Q26. You create two mappings that both use the same changed data and run at different times. One runs every 15 minutes and the other runs once every day.
What must you do to ensure that the Mapping that gets executed more often does not consume the changed data required by the other Mapping?(Choose the best answer.)
A. Use Consistent CDC, do not perform a purge of the journal data when the first Mapping gets executed, and manually change theJRN_SUBSCRIBERcolumn in the correspondingJ$table to keep the changed data present for the second Mapping.
B. Create a third mapping to copy the changed data to a staging table, which is used as the source of the second Mapping.
C. Duplicate the source data store for each Mapping.
D. Create two distinct subscribers for each Mapping.
Q27. You have to loop through a Mapping step three times in a package by using variables. Identify thecorrect variable data type to create the loop. (Choose the best answer.)

B. Use automatic distribution feature at the models level to automatically create the submodels and move the data stores based on their names.
C. Create new submodels and leverage the automatic distribution feature at the submodels level to automatically move the data stores based on their names.
D. Create new models, drag the data stores individually to each model and then drag the models to the parent model to create submodels.
