NEW QUESTION # 47
Which two cloud services allow you to import Data Pump files to an Autonomous Database on Dedicated Infrastructure? (Choose two.)
Answer: C,D
Explanation:
Importing Data Pump files into an Autonomous Database on Dedicated Infrastructure requires compatibility with Oracle-managed cloud storage services:
Correct Answer (C): Oracle Cloud Infrastructure Object Storage Classic is an older OCI storage service that supports Data Pump imports. Users can upload dump files to a Classic bucket and use the DBMS_CLOUD package to import them into the database.
Correct Answer (E): Oracle Cloud Infrastructure Object Storage (the modern OCI Object Storage) is fully supported for Data Pump imports, offering scalability and integration with Autonomous Database via DBMS_CLOUD.
Incorrect Options:
A: Amazon S3 is not natively supported for direct Data Pump imports into Autonomous Database on Dedicated Infrastructure without additional integration steps.
B: Azure Blob Storage is similarly unsupported natively; Autonomous Database prioritizes OCI storage.
D: Google Cloud Storage is not integrated for this purpose.
These OCI services ensure seamless and secure data migration.
NEW QUESTION # 48
Which statement is FALSE about Autonomous Database maintenance on Dedicated Infrastructure?
Answer: C
Explanation:
Full Detailed In-Depth Explanation:
Maintenance on dedicated infrastructure:
A: True. You can adjust maintenance windows for container databases.
B: False. Exadata Infrastructure maintenance (e.g., OS, grid patching) is separate from container database patching, which occurs independently.
C: True. Oracle reschedules missed maintenance to the next quarter.
D: True. Infrastructure maintenance occurs quarterly.
NEW QUESTION # 49
What is the difference between Autonomous Data Warehouse (ADW) and Autonomous Transaction Processing (ATP) databases?
Answer: B
Explanation:
ADW and ATP are tailored for different workloads:
Correct Answer (C): “Only ADW uses columnar compression by default” is true. ADW employs Hybrid Columnar Compression (HCC) for analytics, optimizing storage and query performance, while ATP uses row-based storage for transactional workloads (though HCC can be enabled manually).
Incorrect Options:
A: Both ADW and ATP manage optimizer statistics automatically.
B: Autoscaling is supported by both ADW and ATP.
D: Automatic backups are standard for both.
This reflects their design focus: ADW for analytics, ATP for transactions.
NEW QUESTION # 50
Your customer wants to permanently disable scheduled maintenance on Autonomous Dedicated Infrastructure to keep their current database version. How can they achieve this?
Answer: D
Explanation:
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.
NEW QUESTION # 51
Which two actions can you perform with Autonomous Data Guard enabled on Autonomous Database on Shared Infrastructure? (Choose two.)
Answer: A,D
Explanation:
Autonomous Data Guard on Shared Infrastructure enhances ADB availability with standby databases. The two correct actions are:
Switchover (C): A switchover swaps roles between the primary and standby databases in a planned manner, with no data loss (RPO = 0). You initiate this via the OCI console (e.g., “Switchover” button on the primary ADB’s Data Guard section) or API (e.g., oci db autonomous-database switchover). For example, before maintenance on the primary, you switch to the standby in another region (e.g., from us-ashburn-1 to us-phoenix-1), taking ~2 minutes (RTO ≈ 2 min). This ensures continuity without downtime, as the standby becomes primary seamlessly.
Failover (D): A failover promotes the standby to primary during an unplanned outage (e.g., primary region failure), also with RPO = 0 due to synchronous replication. Trigger it via the OCI console (e.g., “Failover” on the standby) or API (e.g., oci db autonomous-database failover). For instance, if us-ashburn-1 crashes, the standby in us-phoenix-1 takes over in ~2 minutes, preserving all committed transactions. It’s automatic in some cases (e.g., severe failure), but manual initiation is supported too.
The incorrect options are:
View Apply Lag (A): While relevant in traditional Data Guard (measuring replication delay), Autonomous Data Guard on shared ADB uses synchronous replication (zero lag), and apply lag isn’t a user-actionable metric exposed in the UI—monitoring focuses on role status, not lag.
Reinstate (B): Reinstatement (restoring a failed primary as a standby) isn’t a user action in shared infrastructure. Oracle manages post-failover recovery, and users can’t manually reinstate; a new standby might be provisioned instead.
Change Protection Mode (E): Traditional Data Guard offers modes (e.g., Maximum Availability), but in Autonomous Data Guard on shared infrastructure, the mode is fixed (synchronous, akin to Maximum Availability), and users can’t modify it—control is limited to switchover/failover.
These actions ensure high availability with user-initiated role changes.
