70. Frage
Which of the following two statements regarding Data Transforms are correct? (Choose two.)
Antwort: A,B
Begründung:
Data Transforms is a feature in Autonomous Database for designing data transformations. The two correct statements are:
Data Transforms allows you to design data transformations in the form of data loads, data flows, and workflows (B): True. Data Transforms provides a graphical interface to create data loads (importing data), data flows (transforming data), and workflows (sequencing operations), simplifying ETL processes within ADB.
All capabilities to transform data in ODI Classic are available with ODI Web Edition (D): True. Oracle Data Integrator (ODI) Web Edition, which integrates with Data Transforms, retains the full transformation capabilities of ODI Classic, adapted for a web-based interface.
The incorrect statements are:
Data Transforms provides access to Oracle Data Integrator (ODI) Web Edition (A): False. Data Transforms is a distinct tool within ADB; while it leverages ODI under the hood, it does not directly provide access to ODI Web Edition as a standalone product.
Workflows for Data Transforms are only available on the ODI Web Edition (C): False. Workflows are part of Data Transforms itself, not exclusive to ODI Web Edition.
These features enhance data integration in ADB.
71. Frage
Which three advanced options can you enable or disable while creating a business model? (Choose three.)
Antwort: A,B,E
Begründung:
When creating a business model in Autonomous Database (e.g., via Data Modeler), advanced options enhance analytical capabilities:
Correct Answer (A): Autonomous Aggregate Cache uses dimensional metadata to manage caching, improving query performance.
Correct Answer (B): Analytic View Transparency View exposes analytic views as standard views for compatibility with existing tools.
Correct Answer (C): Analytic View Base Table Query Transformation enables seamless integration of analytic views into existing reports.
Incorrect Options:
D: "Display private tables" is not a recognized advanced option in this context.
E: "Business Object Security Feature" is unrelated to Autonomous Database business modeling.
These options optimize analytical workloads.
72. Frage
Your customer wants to permanently disable scheduled maintenance on Autonomous Dedicated Infrastructure to keep their current database version. How can they achieve this?
Antwort: A
Begründung:
Oracle Autonomous Database on Dedicated Infrastructure enforces automatic maintenance to ensure security, stability, and performance. The correct answer is:
You cannot permanently disable scheduled Automatic Maintenance (C): Oracle mandates periodic maintenance updates (e.g., patching) to keep the database secure and compliant with the latest fixes. Customers can influence the timing of these updates but cannot disable them permanently. This is a design principle of the Autonomous Database service to reduce administrative overhead while maintaining system integrity.
The incorrect options are:
Change the Automatic Maintenance Schedule to 'No Preference' (A): This setting allows Oracle to determine the maintenance window but does not disable maintenance. It still occurs as scheduled by Oracle.
Change the Automatic Maintenance Schedule to 'None' (B): There is no 'None' option in the maintenance scheduling settings for Autonomous Dedicated Infrastructure. This is not a valid configuration.
Change the Automatic Maintenance Schedule to 'Specify a Schedule' but do not select any month, week, or day (D): This is not a functional workaround. Specifying a schedule requires selecting a valid time window, and leaving it blank does not prevent maintenance; it simply reverts to Oracle's default scheduling.
Oracle's documentation confirms that while customers can reschedule or skip specific maintenance runs (up to two consecutive quarters), permanently disabling automatic maintenance is not permitted to ensure the system remains up-to-date and secure.
73. Frage
Which two statements are true when running DBMS_CLOUD.COPY_DATA? (Choose two.)
Antwort: D,E
Begründung:
DBMS_CLOUD.COPY_DATA loads data into Autonomous Database:
Correct Answer (B): "The source files can reside in Oracle Object Storage, Amazon S3 Object Storage, or Azure Blob Storage" is true. The procedure supports these cloud storage services with proper credentials.
Correct Answer (E): "A valid credential must be created prior to running the DBMS_CLOUD.COPY_DATA procedure" is true. Credentials (e.g., via DBMS_CLOUD.CREATE_CREDENTIAL) authenticate access to the source storage.
Incorrect Options:
A: Source files are not automatically removed; deletion requires separate action.
C: The target table must exist; COPY_DATA doesn't create it.
D: Archive Storage isn't supported; only Standard Storage is compatible.
This enables flexible data loading from cloud storage.
74. Frage
Which two are correct actions to take in order to download the Autonomous Database Credentials? (Choose two.)
Antwort: B,C
Begründung:
Downloading Autonomous Database credentials (client wallet) is necessary for secure connections. The two correct actions are:
Find the service console for your Autonomous Database, then pick administration, then download the credential wallet (B): In the OCI console, navigate to the Autonomous Database service console (e.g., via the "Database" section). Select your ADB instance, go to the "Administration" tab, and click "Download Client Credentials (Wallet)." You'll set a password and download a ZIP file containing files like tnsnames.ora and certificates. This method is straightforward for DBAs managing the instance directly from its service page.
Click on the Autonomous Database in the menu, click a database name, then choose DB Connection button, then download the wallet (D): From the OCI console's main navigation, go to "Autonomous Database," select your database by name, and click the "DB Connection" button on the details page. Then, select "Download Wallet," provide a password, and download the ZIP file. This is a common path for users accessing connectivity details directly from the database overview.
The incorrect options are:
Click the compute section of the menu, then choose instance configurations, then download wallet (A): The "Compute" section is for virtual machines, not databases. Credentials are tied to the ADB service, not compute instances.
Click on the Object Storage and find your Autonomous bucket and download the wallet credentials (C): Object Storage holds user data or backups, not the wallet credentials, which are generated and downloaded from the ADB service interface.
Both B and D provide secure access to the wallet for tools like SQL Developer.
