sqlnet.ora
cwallet.ssoE. ojdbc.properties

Answer: B

5. What are three methods to load data into the Autonomous Database? (Choose three.)

Oracle GoldenGate
Transportable Tablespace
RMAN Restore
Oracle Data PumpE. SQL*Loader

Answer: ADE

Explanation:

6. In which way can a SQL Developer help you test your data loading scenario to AutonomousDatabase (ADB)?

In the TEST phase of the wizard, a subset of accepted records is displayed based on yourdefinition.
In the TEST phase of the wizard a list is generated containing the records that would berejected during import.
In the Column Definition Phase, the system cross-references with the file-contents andshows the conflicts with the definition.
In the TEST phase, a temporary table will be populated with the records before insertingthem in the destination table.

Answer: C

7. Which three statements are correct when the Autonomous Database is stopped? (Choosethree.)

User with DWROLE can still access the database.
Tools are no longer able to connect to a stopped instance.
CPU billing is halted based on full-hour cycles of usage.
In-flight transactions and queries are stopped.

Answer: BCD

Explanation:Reference: https://docs.oracle.com/en/cloud/paas/autonomous-data-warehouse-cloud/user/autonomousstop.html#GUID-9AF677F3-027A-43FD-B018-9F4A42D5CDE9

8. A customer wants to migrate to Autonomous Database (ADB) but only allows for a very smallwindow of downtime. Golden Gate was advised to be used during the migration. For maximumreassurance of their end-users, the customer also would like to use Golden Gate as a fall-backscenario for the first 6 months after the migration. If customers complain, the on-premise datacan be synchronised with the ADB Instance for a switch back.Which statement about the migration using Golden Gate is correct?

Migration to ADB is not possible using Golden Gate because the apply-process cannot beinstalled 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 existsfor this.
The fallback scenario is not possible using Golden Gate because the capture-process cannotbe installed on ADB.
The described scenario is correct, can be used for migration and fallback scenarios.

Answer: B

9. What is the predefined role that exists in Autonomous Database that includes common privileges that are used by a Data Warehouse developer?

ADBDEV
ADMIN
DWROLE
ADWC

Answer:C

Explanation:

10. What are two advantages of using Data Pump to migrate your Oracle Databases to Autonomous Database? (Choose two.)

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.
Data Pump creates the table spaces used by your Autonomous Database.

Answer: AC

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

The DBMS_CLOUD.PUT_OBJECT procedure copies a file from Cloud Object Storage to theAutonomous Data Warehouse.
The DBMS_CLOUD.CREATE_CREDENTIAL procedure stores Cloud Object Storagecredentials in the Autonomous Data Warehouse database.
The DBMS_CLOUD.VALIDATE_EXTERNAL_TABLE procedure validates the source files foran external table, generates log information, and stores the rows that do not match the formatoptions specified for the external table in a badfile table on Autonomous Data Warehouse.
The DBMS_CLOUD.DELETE_FILE procedure removes the credentials file from theAutonomous Data Warehouse database.
The DBMS_CLOUD.CREATE_EXTERNAL_TABLE procedure creates an external table onfiles in the cloud. You can run queries on external data from the Autonomous Data Warehouse.

14. While Autonomous Transaction Processing and Autonomous Data Warehouse use thesame Oracle database, which statement is true about the workloads?

Autonomous Transaction Processing memory usage optimizes workloads for parallel joinsand aggregations.
Autonomous Data Warehouse workloads are optimized for mixed workloads.
Autonomous Transaction Processing workloads are optimized for data warehouse, datamart, and data lake.
Data that is bulk loaded, by default, uses the row format in Autonomous TransactionProcessing where Autonomous Data Warehouse data format is columnar.

Answer: B
