NEW QUESTION # 40
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. Copy the encryption wallet from the on-premises DB to the Cloud DB System.
- B. Use the dbcli dbstorage command to identify the DATA, RECO, and REDO locations.
- C. Make sure that the SYS user password is identical on both systems.
- D. Perform an RMAN backup of the on-premises DB to OCI Cloud Storage.
Answer: A
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 # 41

- A. A best practice is to invoke Data Pump using SYS as SYSDBA
- B. It supports cross-endian formats
- C. Both the source and target database must be of the same version
- D. It supports cross-platform migration
Answer: B,D
Explanation:
Data Pump is a versatile Oracle utility that facilitates high-speed data transfer between Oracle databases. It indeed supports cross-endian formats, meaning it can handle data migration between systems with different byte orders. Additionally, Data Pump supports cross-platform migration, allowing for the movement of data across different operating systems and architectures, making it a valuable tool for database migration projects.
NEW QUESTION # 42
You are migrating a non TDE encrypted on-premises Database to an OCT Database Service Instance ising RMAN. You set up the DB Cloud Backup Module, but when executing the RMAN command to create your Cloud Backup you see the following error: AANA RMAN-03009: failure of backup command on ORA_SBT_TAPE 1 channel at: 08/18/2014 11: ORA-19914: unable to encrypt backup ORA~29361 mastor key not yet set What are the TWO causes of this error? (Choose all correct answers)
- A. The Set ENCRYPTION IDENTIFIED BY command was executed.
- B. The set DECRYPTION IDENTIFIED BY RMAN command was not executed.
- C. The Set ENCRYPTION IDENTIFIED BY only command was executed
- D. SET ENCRYPTION ON
- E. He OCT Object Storage eye on at rest key is missing
Answer: D,E
Explanation:
The error ORA-19914 indicates encryption issues during RMAN backup to cloud storage. Enabling encryption with "SET ENCRYPTION ON" without a proper encryption key or missing the Object Storage encryption-at-rest key can lead to this error. Ensuring encryption keys are correctly configured and accessible is crucial for successful RMAN backups to the cloud.
