NEW QUESTION # 59
Which three statements are true about procedures in the DBMS_CLOUD package? (Choose three.)
- A. 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.
- B. The DBMS_CLOUD.DELETE_FILE procedure removes the credentials file from the Autonomous Data Warehouse database.
- C. 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.
- D. The DBMS_CLOUD.CREATE_CREDENTIAL procedure stores Cloud Object Storage credentials in the Autonomous Data Warehouse database.
- E. The DBMS_CLOUD.PUT_OBJECT procedure copies a file from Cloud Object Storage to the Autonomous Data Warehouse.
Answer: A,C,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.
NEW QUESTION # 60
What can you do with graphs? (Choose two)
- A. 3-D modeling
- B. Find patterns that are anomalous and use that to detect fraud.
- C. Facial recognition
- D. Product recommendations
Answer: B
Explanation:
Graphs are data structures that represent the connections and relationships between entities, such as people, products, places, etc. Graphs can be used to perform various types of analysis based on these connections, such as finding patterns that are anomalous and use that to detect fraud1 or generating product recommendations based on the preferences and behaviors of similar customers2. 3-D modeling and facial recognition are not applications of graphs, but rather of other types of data analysis techniques, such as computer graphics and machine learning34.
