NEW QUESTION # 20
Which type of checks is NOT supported by Oracle Data Integrator (ODI)?
- A. references
- B. mandatory attributes
- C. conditions
- D. business rule
- E. keys
Answer: D
Explanation:
Oracle Data Integrator (ODI) supports various types of checks, including conditions, keys, references, and mandatory attributes, but it does not inherently enforce business rules. Business rules, which are higher-level validations and constraints defined by business logic, are typically implemented at the application level or within the database through triggers or stored procedures.

- B. Logical Migration only
- C. ZDM does not support Inflight Upgrade.
- D. Physical Migration only
Answer: B
Explanation:
For Inflight Upgrade scenarios, Zero Downtime Migration (ZDM) supports Logical Migration only. Logical migration involves capturing and transforming the database schema and data into a logical format before transferring it to the target system, which is suitable for upgrades that involve significant changes to the database structure or version.
NEW QUESTION # 30
When preparing for a migration using RMAN DUPLICATE from an active database, which two actions do you need to take if the on-premises database (DB) is Transparent Data Encryption (TDE) encrypted?
- A. Use the dbcli dbstorage command to identify the DATA, RECO, and REDO locations.
- B. Copy the encryption wallet from the on-premises DB to the Cloud DB System.
- C. Perform an RMAN backup of the on-premises DB to OCI Cloud Storage.
- D. Make sure that the SYS user password is identical on both systems.
Answer: B
Explanation:
When migrating a TDE-encrypted database using RMAN DUPLICATE, it's crucial to copy the TDE wallet from the on-premises database to the Cloud DB system. This ensures that the cloud database can decrypt the data, as the encryption keys contained in the wallet are necessary for accessing the encrypted data.

NEW QUESTION # 32
When integrating data from multiple sources into a Data Warehouse schema, you want to check a length constraint that you have imposed on one of the target columns before the rows arrive in the target table. All the rows that do not pass this quality check will have to be isolated in error tables. For this, you have chosen an Integration Knowledge Module (IKM) that supports flow control. You have also chosen the value raue for this parameter to enable this check. At compile time, you see that Oracle Data Integrator (ODI) throws an error and the execution cannot start. What is the reason?
- A. Primary key was not defined on the target table.
- B. There were no rows compliant with imposed constraint.
- C. The Check Knowledge Module was not set in the physical design.
- D. The integration type was not set in the logical design.
Answer: C
Explanation:
When using Oracle Data Integrator (ODI) for data integration with flow control to check constraints, it's essential to set the Check Knowledge Module in the physical design. If this module is not set, ODI cannot perform the required checks during the integration process, leading to errors at compile time and preventing the execution from starting.
NEW QUESTION # 33
You are creating a data integration mapping in Oracle Data Integrator (ODI). Your source tables are in an on-premises Oracle Database.
Which three items from the source tables can be retrieved by reverse-engineering a model? (Choose three.)
- A. Table owner
- B. Data types
- C. Table Statistics
- D. Constraints
- E. Column names
Answer: B,D,E
Explanation:
Reverse-engineering a model in Oracle Data Integrator (ODI) from source tables in an on-premises Oracle Database retrieves metadata such as constraints (e.g., primary keys, foreign keys), column names, and data types. This information is crucial for creating accurate and functional data integration mappings in ODI.
NEW QUESTION # 34

NEW QUESTION # 35
When building out your private subnet, you realize you need a host within your network in order to get access to the rest of your Oracle Cloud Infrastructure instances. Which type of host should you set up to get around this constraint?
- A. Encrypted host
- B. Isolation host
- C. Baston host
- D. Private host
Answer: C
Explanation:
A Bastion host is used within a network, especially in a private subnet, to provide secure access to Oracle Cloud Infrastructure instances. It acts as a gateway, enabling controlled access to internal instances from an external network, thereby enhancing the security posture by limiting direct exposure of instances to the public internet.
NEW QUESTION # 36
You have executed the mappings with Change Data Capture ( CDC ) on the source data store and you are now going through the code in the operator log for debugging. Which two tables or view do you need to inspect in the database to see whether the CDC process is writing changed data or not in Oracle Data Integration ( ODI )? (Choose all correct answers)
- A. JV$ view
- B. JW$ view
- C. JV$D view
- D. J$ table
Answer: C,D
Explanation:
In Oracle Data Integrator (ODI) Change Data Capture (CDC) processes, the JV$D view and J$ table are critical components for monitoring changed data capture activities. The JV$D view provides information about the CDC subscriber view definitions, while the J$ table stores the actual changed data records. Inspecting these database objects can help debug and verify that the CDC process is correctly capturing and writing changed data.
