Question 1

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.)

Options :

A :

Use Consistent CDC, do not perform a purge of the journal data when the first Mapping gets executed, and manually change the JRN_SUBSCRIBER column in the corresponding J$ 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.

Answer: A

Question 2

Identify two constraints that can be used to ensure uniqueness in ODI. (Choose two.)

Options :

A : conditions

B : foreign keys

C : primary keys

D : alternate keys

E : not null

Answer: B,E

Question 3

Which two objects can be dragged to a Mapping? (Choose two.)

Options :

A : Variables

B : Datastores

C : Knowledge Modules

D : Reusable Mappings

Answer: B,D

Question 4

Identify two correct statements about reusable Mappings. (Choose two.)

Options :

A : They can have generic input and output signatures.

B : They contain both a Logical and Physical Mapping design.

C : They can be used within regular Mappings.

D : They can be executed directly.

E : They can be shared across projects.

Answer: A,B

Question 5

How would a Knowledge Module, that is required to perform an aggregation in a Mapping, generate the correct code? (Choose the best answer.)

Options :

A :

The Knowledge Module must be customized because business rules and the physical implementation are strictly interlayed in ODI.

B : The Knowledge Module must be customized only for aggregation functions.

C :

The Knowledge Module need not be customized because aggregation code is generated automatically by ODI according to the Mapping logic.

D :

The Knowledge Module need not be customized, but a variable must be used in the aggregate expression to generate the correct sum.
