Question 1

Question
What are two advantages of using Data Pump to migrate your Oracle Databases to Autonomous Database? (Choose two.)
Answer
  • Data Pump can exclude migration of objects like indexes and materialized views that are not needed by Autonomous Database.
  • Data Pump is platform independent - it can migrate Oracle Databases running on any platform.
  • Data Pump is faster to migrate database than using RMAN (= Recovery MANager).
  • Data Pump creates the tablespaces used by your Autonomous Database.

Question 4

Question
Which three statements are true about procedures in the DBMS_CLOUD package? (Choose three.)
Answer

The Oracle adviser recommends to use Oracle Data Sync for this. Which statement is true regarding Oracle Data Sync?
Answer
  • Data Sync can only load files into tables (insert-only), the customer has to write the additional code.

Question 18

Question
The 3rd party application that your customer wants to migrate to Autonomous Database (ADB) has some specific demands like tablespace names, usernames and init.ora parameters. The decision was made to adhere to the suggested migration method using an instant client and the datapump version that was suggested (and came with it). Which statement is true about the migration of the application's database success?
Answer
  • The migration can be technically a success but the 3-rd party vendor needs to support the result
  • The suggested datapump version will create an alias for non-standard tablespace names so the migration is successful.
  • The tablespace names will result in a blocking error during datapump import because of ADB limitations
  • The migration can be a success, both technically and functional due to datapump enhancements

Question 19

Question
A customer wants to migrate to Autonomous Database (ADB) but only allows for a very small window of downtime. Golden Gate was advised to be used during the migration.

If customers complain, the on-premise data can be synchronised with the ADB Instance for a switch back. Which statement about the migration using Golden Gate is correct?
Answer
  • Migration to ADB is not possible using Golden Gate because the apply-process cannot be installed on ADB
  • Only the migration to ADB is possible from an on-premise installation of Golden Gate
  • Golden Gate on premise is not certified with ADB because Golden Gate Cloud Service exists for this
  • The fallback scenario is not possible using Golden Gate because the capture-process cannot be installed on ADB
  • The described scenario is correct, can be used for migration and fallback scenarios

Question 20

Question
Which statement is true regarding database client credentials file required to connect to your Autonomous Database?
Answer
  • Place the credential files on a share drive that all users can use to connect to the database
  • The Transparent Data Encryption (TDE) wallet can be used for your client credentials to connect to your database

Question 21

Question
In which way can a SQL Developer help you test your data loading scenario to Autonomous Database (ADB)?
Answer

  • In the TEST phase of the wizard a list is generated containing the records that would be rejected during import.
  • In the Column Definition Phase, the system cross-references with the file-contents and shows the conflicts with the definition
  • In the TEST phase, a temporary table will be populated with the records before inserting them in the destination table
