Question 1 of 36

You have been tasked with designing a Mapping that must perform an initial load and incremental updates using the same transformation logic. How should you proceed? (Choose the best answer.)

Create a single Mapping with two Physical Designs: one for the initial load and one for the incremental updates.

Create a single Mapping with a single Physical Design and modify it appropriately when an initial load is required or when an incremental update is required.

Create two Mappings: one for the initial load and one for the incremental updates. Duplicate the transformation logic.

Create a single Mapping and use variables in the Logical Design to do an initial load when required or an incremental update otherwise.

Correct Answer: A

To design a Mapping that performs both an initial load and incremental updates using the same transformation logic, the best approach is to create a single Mapping with two Physical Designs: one tailored for the initial load and the other for incremental updates. This allows for flexibility and avoids duplication of transformation logic, ensuring that both processes can coexist within the same framework.

Question 2 of 36

How are the ODI repositories upgraded? (Choose the best answer.)

by using Opatch

by using ODI Studio

by using the import/export utilities

by using Upgrade Assistant

Correct Answer: D

The correct method for upgrading ODI repositories is by using the Upgrade Assistant. This tool is specifically designed to help with the upgrade process of Oracle components, including ODI repositories, ensuring a smooth transition from older versions to newer ones.

Question 3 of 36

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.)

The project must be explicitly mapped within an ODI mapping.

A customize knowledge module is needed.

An ODI procedure must be associated with it.

It can be defined for every technology listed in the topology.

Correct Answer: D

To address the requirement of translating commands with different syntax but the same functionality across different technologies in ODI, the feature you need is the capability to define user functions for every technology listed in the topology. This means you can create a function once and map it to the specific syntax required by various target technologies, ensuring consistent functionality regardless of the underlying technology.

Question 4 of 36

You want to ensure that the Physical Mapping Design cannot be modified even if the Logical Design of the Mapping is changed. What sequence of steps must you follow to achieve this? (Choose the best answer)

Go to the Physical tab, select the Fixed Design check box of the Physical Mapping Design.

Go to the Physical tab, select the Is Frozen check box of the Physical Mapping Design.

Go to the Physical tab, select the Read-only check box of the Physical Mapping Design.

Go to the Physical tab, deselect the Modify check box of the Physical Mapping Design.

Correct Answer: B

To ensure that the Physical Mapping Design cannot be modified even if the Logical Design of the Mapping is changed, you need to go to the Physical tab and select the Is Frozen check box of the Physical Mapping Design. This option is provided to freeze the design, thereby preventing any modifications irrespective of changes in the logical design.

Question 5 of 36

Which two statements are true about the Oracle Data Integrator Software Development Kit (ODI SDK)? (Choose two.)

It enables developers to execute most ODI operations through a Java program.

It can be used to embed ODI processes into another product.

It is used to load data between Teradata and Oracle.

It must be used by ETL developers to develop ODI processes.

Correct Answer: A, B

The Oracle Data Integrator Software Development Kit (ODI SDK) allows developers to execute most ODI operations through a Java program, which makes option A correct. Additionally, it can be used to embed ODI processes into another product, which makes option B correct. Options C and D are incorrect; the SDK is not specifically about loading data between Teradata and Oracle nor is it specifically required for ETL developers to develop ODI processes.
