NEW QUESTION # 36
You have an on-premises non-TDE-encrypted Linux 19c container database (CDB) that is already being regularly backed up to Oracle Cloud Infrastructure (OCI) Object Storage via the Database Backup Cloud Service. You plan on using Recovery Manager (RMAN) to migrate it to Database Cloud Service. What is the valid strategy to migrate?
- A. Create a new DB Service instance, delete the existing database, manually install the DB Cloud Backup Module pointing it to the backed where the on-premises backups are located, and perform a complted RMAN RESTORE AS encryption operation.
- B. Create a new OCI DB Service Instance, copy the backup data from the bucket to the FRA, and then use the console to perform a DB restore.
- C. Create a new OCI DB Service instance, delete the existing database, and use the DBaa$ tooling to configure the DB Cloud Backup Module to point to the existing bucket, and then restore the backup by using the console.
- D. Create a new OCI DB Service instance and use the "instantiate from backup" option in the console. This will automatically take care of the encryption.
Answer: D
Explanation:
For migrating a non-TDE-encrypted 19c CDB to Database Cloud Service using RMAN and backups stored in OCI Object Storage, the "instantiate from backup" option simplifies the process. This method automatically handles the necessary encryption for the cloud environment, streamlining the migration and ensuring compliance with cloud security standards.

You have a requirement to join data from an Oracle database table and a flat file and load into target DB2 table, using Oracle Data Integrator (ODI). Which statement is correct about this?
- A. It is possible to join data from different source connection types in mapping, but the result must be loaded to Oracle.
- B. Flat file data has to have a header row in order to join with Oracle database table in a single mapping
- C. Heterogeneous sources and targets are possible in a single mapping only if there is no incremental data load.
- D. It is not possible to join data from different source connection types in a Single mapping
- E. It is possible to mix heterogeneous source connection type and load into any supported target connection type in a single mapping.
Answer: E
Explanation:
Oracle Data Integrator (ODI) supports the integration of heterogeneous data sources, including databases and flat files, within a single mapping. This capability allows for the joining of data from different source types, such as an Oracle database table and a flat file, and loading the combined data into a target database like DB2. ODI's flexible architecture and support for various technologies enable this seamless integration, facilitating complex data transformation and loading tasks across diverse data environments.

NEW QUESTION # 41
You took a backup to DISK on the on-premises database and copied it to an Object Storage bucket to be used to instantiate a new Database Cloud Service.
Which RMAN operation is required before the backup can be restored?
- A. export backuppiece
- B. encrypt backup
- C. uncompress backup
- D. decrypt backup
Answer: D
Explanation:
Before restoring a TDE-encrypted backup from an on-premises database to a Cloud Database Service, the RMAN operation required is to decrypt the backup if the encryption keys or wallet are not available in the target environment. This ensures the backup can be restored without encryption constraints in the new environment.
NEW QUESTION # 42
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. Make sure that the SYS user password is identical on both systems.
- B. Perform an RMAN backup of the on-premises DB to OCI Cloud Storage.
- C. Use the dbcli dbstorage command to identify the DATA, RECO, and REDO locations.
- D. Copy the encryption wallet from the on-premises DB to the Cloud DB System.
Answer: D
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.

Which TWO statements are true about online pluggable database (PDB) relocation? (Choose all correct answers)
- A. Database version downgrade can be achieved with PDB relocation.
- B. PDB relocation with no version change can be performed with near-zero downtime.
- C. Online PDB relocation can achieve a zero downtime upgrade.
- D. A PDB with the ASCII character set can be relocated to a container database (CDB) with the AL32UTF8 character set.
Answer: B,D
Explanation:
Online Pluggable Database (PDB) relocation allows for the movement of a PDB from one CDB to another with minimal disruption. It supports relocating a PDB with an ASCII character set to a CDB with the AL32UTF8 character set, enabling character set conversion. Furthermore, PDB relocation can achieve near-zero downtime when there is no version change between the source and target CDBs, enhancing operational continuity.
NEW QUESTION # 51
Which type of Zero Downtime Migration (ZDM) can you use for Inflight Upgrade?
- A. Physical Migration only
- B. ZDM does not support Inflight Upgrade.
- C. Logical Migration only
- D. Both Physical and Logical Migration is supported.
Answer: C
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 # 52
Which statement is true?
- A. One PDB consists of multiple CDBs.
- B. One CDB can have one or more PDBs.
- C. One CDB can have only one PDB.
- D. One PDB consists of only one CDB.

Oracle Zero Downtime Migration (ZDM) uses MySQL internally, configuring on a default port number. What will ZDM proceed to, if a port number is not specified and the default is not available?
- A. Assign a random port number.
- B. Request a valid port number
- C. Increase the default port number by one and retry five times.
- D. Exit the installation with an error message.
Answer: C
Explanation:
If Oracle Zero Downtime Migration's (ZDM) default MySQL port is unavailable and no alternative is specified, ZDM will increment the default port number by one and retry up to five times to find an available port, ensuring the internal MySQL instance used by ZDM can operate without port conflicts.
NEW QUESTION # 55
You have a security requirement within your organization to separate your resources. There is a team that supports each resource and they are not allowed access to the other resources.
Which security control with Oracle Cloud Infrastructure meets this requirement?
- A. Key Management
- B. Federation
- C. Compartments and Policies
- D. Tagging
Answer: C

NEW QUESTION # 56
Which two ports are required for ZDM to communicate between the source and target database servers and perform a successful physical online database migration? (Choose two.).
- A. Port 22 on the source and Target Database
- B. Port 443 on the Source and Target Database
- C. Port 1521 on the source and Target Database
- D. Port 455 on the Source and Target Database
Answer: A,C
Explanation:
For ZDM to communicate between the source and target database servers during a physical online migration, Port 22 (SSH) is used for secure shell access, and Port 1521 (Oracle Net Listener) is used for database connections. These ports must be open to enable ZDM to execute commands and transfer data.
