質問 # 63
Oracle Data Safe is a unified control center for your Oracle databases which helps you understand the sensitivity of your data, evaluate risks to data, mask sensitive data, implement and monitor security controls, assess user security, monitor user activity, and address data security compliance requirements. Which statement is FALSE for Oracle Data Safe?
正解：C
解説：
Oracle Data Safe enhances database security across various Oracle environments. The false statement is:
Oracle Data Safe only supports Autonomous Database (D): This is incorrect. Oracle Data Safe supports a wide range of Oracle databases, not just Autonomous Database. It works with Autonomous Database (shared and dedicated), Oracle Database Cloud Service (VM and Bare Metal), Exadata DB Systems, on-premises Oracle Databases, and Oracle Database on OCI Compute. For example, a DBA could use Data Safe to mask sensitive data in an on-premises 19c database or assess security in an Exadata Cloud@Customer deployment, not just ADB. This broad compatibility makes it a unified security tool across Oracle’s ecosystem.
The true statements are:
Oracle Data Safe helps you find sensitive data in your database by inspecting the actual data in your database and its data dictionary (A): Data Safe’s Data Discovery feature scans tables and metadata to identify sensitive columns (e.g., SSNs, credit card numbers), using predefined and custom patterns.
Oracle Data Safe helps you assess the security of your cloud database configurations by analyzing database configurations (B): The Security Assessment feature evaluates settings like encryption, auditing, and privileges, providing risk scores and recommendations.
Oracle Data Safe evaluates user types, how users are authenticated, and the password policies assigned to each user (C): User Assessment analyzes user accounts, authentication methods (e.g., password, SSO), and policies, highlighting risks like weak passwords.
The misconception in D limits Data Safe’s scope, which extends beyond ADB to all supported Oracle databases.
質問 # 64
Your customer wants to permanently disable scheduled maintenance on Autonomous Dedicated Infrastructure to keep their current database version. How can they achieve this?
正解：D
解説：
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.
質問 # 65
Which two statements are true when running DBMS_CLOUD.COPY_DATA? (Choose two.)
正解：A、C
解説：
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.
質問 # 66
How do you change the tablespace quota for user MTHEO on an Autonomous Database on Shared Infrastructure?
正解：A
解説：
Full Detailed In-Depth Explanation:
In Autonomous Database on Shared Infrastructure, tablespace quotas are managed using standard SQL commands, as administrative packages like DBMS_CLOUD_ADMIN are restricted in this environment. The correct method is:
ALTER USER MTHEO QUOTA UNLIMITED ON TABLESPACE DATA: This command directly modifies the user’s quota on the DATA tablespace, which is the default tablespace in Autonomous Database. “UNLIMITED” removes any storage restrictions.
Analysis of options:
A: Incorrect. DBMS_CLOUD_ADMIN is used in dedicated infrastructure for advanced administrative tasks, not shared infrastructure for quota changes.
B: Correct. This is the standard SQL syntax supported in shared infrastructure.
C: Incorrect. ALTER TABLESPACE modifies tablespace properties, not user quotas, and isn’t applicable here.
D: Incorrect. ALTER DATABASE syntax is invalid for user quotas; it’s for database-wide settings.
質問 # 67
What two actions can you do when a refreshable clone passes the refresh time limit? (Choose two.)
正解：B、D
解説：
A refreshable clone in Autonomous Database is a read-only copy of a source database that syncs periodically, but it has a refresh time limit (typically 7 days). Once this limit is exceeded, specific actions are available. The two correct options are:
You can disconnect from the source to make the database a read/write database (B): After the refresh time limit passes, the clone can no longer sync with the source. You can “disconnect” it (via the OCI console or API, e.g., oci db autonomous-database update --is-refreshable-clone false), converting it into an independent, read/write Autonomous Database. This requires a new license and incurs full costs, but it allows modifications (e.g., INSERT or UPDATE) that were blocked in read-only mode. For example, a test clone might be disconnected to become a production instance after testing.
You can use the instance as a read-only database (C): Even after the refresh limit, the clone remains functional as a read-only database, retaining its last refreshed state. You can query it (e.g., SELECT * FROM sales) for analysis or reporting without further refreshes, though it won’t reflect source updates. This is useful if ongoing read-only access suffices without needing write capabilities.
The incorrect options are:
You can manually refresh the clone (A): False. Once the refresh time limit (e.g., 7 days) is exceeded, manual refreshes are not possible. The clone’s refresh capability expires, and it can’t sync again unless recreated. This is a fixed constraint to manage resource usage in ADB.
You can extend the refresh time limit (D): False. The refresh period (set during clone creation, max 7 days) cannot be extended after provisioning. You’d need to create a new clone with a longer limit if needed, but post-expiry, no extension is allowed.
These options provide flexibility post-expiry, balancing read-only continuity and full database conversion.
