NEW QUESTION 35
Which statement is true regarding database client credentials file required to connect to your Autonomous Database?
- A. Store credential files in a secure location and share the files only with authorized users to prevent unauthorized access to the database.
- B. When you share the credential files with authorized users, mail the wallet password and the file in the same email.
- C. Place the credential files on a share drive that all users can use to connect to the database.
- D. The Transparent Data Encryption (TDE) wallet can be used for your client credentials to connect to your database.
Answer: A
Explanation:
Connection to Autonomous DB uses certificate authentication and Secure Sockets Layer (SSL). This ensures that there is no unauthorized access to Autonomous DB and that communications between the client and server are fully encrypted and cannot be intercepted or altered.
Certification authentication uses an encrypted key stored in a wallet on both the client (where the application is running) and the server (where your database service on the Autonomous DB is running). The key on the client must match the key on the server to make a connection There's credentials zip file available for download once ADB is created, the zip file contains a collection of files, that needed to connect to your Autonomous DB. All communications between the client and the server are encrypted Wallet files, along with the Database user ID and password provide access to data in your Autonomous Transaction Processing database. Store wallet files in a secure location. Share wallet files only with authorized users. If wallet files are transmitted in a way that might be accessed by unauthorized users (for example, over public email), transmit the wallet password separately and securely.
For better security, Oracle recommends using restricted permissions on wallet files. This means setting the file permissions to 600 on Linux/Unix.
Similar restrictions can be achieved on Windows by letting the file owner have Read and Write permissions while all other users have no permissions.

NEW QUESTION 39
Which three statements are true about procedures in the DBMS_CLOUD package? (Choose three.)
- A. The DBMS_CLOUD.CREATE_EXTERNAL_TABLE procedure creates an external table on files in the cloud. You can run queries on external data from the Autonomous Data Warehouse.
- B. The DBMS_CLOUD.VALIDATE_EXTERNAL_TABLE procedure validates the source files for an external table, generates log information, and stores the rows that do not match the format options specified for the external table in a badfile table on Autonomous Data Warehouse.
- C. The DBMS_CLOUD.PUT_OBJECT procedure copies a file from Cloud Object Storage to the Autonomous Data Warehouse.
- D. The DBMS_CLOUD.CREATE_CREDENTIAL procedure stores Cloud Object Storage credentials in the Autonomous Data Warehouse database.
- E. The DBMS_CLOUD.DELETE_FILE procedure removes the credentials file from the Autonomous Data Warehouse database.
Answer: A,B,D
Explanation:
DELETE_FILE Procedure
This procedure removes the specified file from the specified directory on Autonomous Data Warehouse.
CREATE_CREDENTIAL Procedure
This procedure stores Cloud Object Storage credentials in the Autonomous Data Warehouse database.
Use stored credentials for data loading or for querying external data residing in the Cloud.
PUTJDBJECT Procedure
This procedure copies a file from Autonomous Data Warehouse to the Cloud Object Storage. The maximum file size allowed in this procedure is 5 gigabytes (GB).
VALIDATE EXTERNAL TABLE Procedure
This procedure validates the source files for an external table, generates log information, and stores the rows that do not match the format options specified for the external table in a badfile table on Autonomous Data Warehouse.
CREATE_EXTERNAL_TABLE Procedure
This procedure creates an external table on files in the Cloud. This allows you to run queries on external data from Autonomous Data Warehouse.
To use Data Pump from ADB, a credential identifying the Object Storage bucket to use must be defined with a DBMS_CLOUD.CREATE_CREDENTIAL function. This will allow ADB to access objects that are stored in the object store , including dump files. To export an existing database to prepare for import into ADB, use the XTP command and add the ex elude option for database functionality that is not recommended or supported in ADB. This will prevent errors during the imp oil process.
This process is not automatic. And if the logs are not moved, you will receive a warning when running the MDB that the logs are not there. In this example, we're moving the log import.log to object store with a DBMS_CLOUD.PUT_OBJECT command.
VALIDATE_EXTERNAL_TABLE Procedure
This procedure validates the source files for an external table, generates log information, and stores the rows that do not match the format options specified for the external table in a badfile table on Autonomous Database. The overloaded form enables you to use the operation_id parameter.
PUT_OBJECT Procedure
This procedure copies a file from Autonomous Database to the Cloud Object Storage. The maximum file size allowed in this procedure is 5 gigabytes (GB) DELETE FILE Procedure This procedure removes the specified file from the specified directory on Autonomous Database.
CREATE_EXTERNAL_TABLE Procedure
This procedure creates an external table on files in the Cloud. This allows you to run queries on external data from Autonomous Database.
