Full Detailed In-Depth Explanation:
Supported formats:

B: True. AVRO is supported for structured data.
C: True. Parquet is optimized for analytics.
D: False. DOC is not supported.
E: True. JSON is flexible for semi-structured data.
F: True. CSV is widely used for tabular data.

NEW QUESTION # 49
You created an Autonomous Database without auto scaling. Which two ways can you enable auto scaling? (Choose two.)

A. Shut down the instance, click Scale Up/Down and select the Auto Scaling checkbox, then restart the instance.
B. Click Scale Up/Down and select the Auto Scaling checkbox.
C. Use a REST call to shut down the instance, then a second REST call to enable Auto Scaling, and a REST call to restart the instance.
D. Use a REST call to enable Auto Scaling.

Answer: B,D

Explanation:
Enabling auto scaling on an existing Autonomous Database can be done without unnecessary complexity:
Correct Answer (A): "Click Scale Up/Down and select the Auto Scaling checkbox" is the simplest GUI method. In the OCI Console, navigate to the database, select "Scale Up/Down," and enable the auto scaling option, allowing up to 3x the base OCPUs dynamically.
Correct Answer (C): "Use a REST call to enable Auto Scaling" leverages the OCI REST API to update the database configuration with the isAutoScalingEnabled parameter set to true. This is ideal for programmatic control.
Incorrect Options:
B: Shutting down the instance is unnecessary; auto scaling can be enabled while the database is running.
D: Multiple REST calls, including shutdown and restart, overcomplicate the process when a single API call suffices.
These methods ensure minimal disruption and efficient resource management.

NEW QUESTION # 50
Which statement is true when connecting an OCI Marketplace image to a shared Autonomous Database?

A. ADB must be configured with NSG
B. Compute Image and Shared ADB must be in the same VCN and Subnet
C. ADB must be configured with Private endpoints
D. Cannot connect OCI Marketplace image to shared ADB

Answer: B

Explanation:
Connecting an OCI Marketplace image (e.g., a compute instance running a preconfigured application) to a shared Autonomous Database (ADB) involves network configuration. The correct statement is:
Compute Image and Shared ADB must be in the same VCN and Subnet (A): For a compute instance from the OCI Marketplace to communicate with a shared Autonomous Database, both must reside in the same Virtual Cloud Network (VCN) and subnet. This ensures direct network connectivity without requiring complex routing or public internet traversal. By default, shared ADB instances use private endpoints within a VCN, and placing the compute instance in the same subnet allows seamless access using the database's private IP address. For example, if the ADB is in subnet 10.0.1.0/24, the compute instance must also be in that subnet to connect via Oracle Net Services (e.g., using a wallet and tnsnames.ora).
The incorrect options are:
ADB must be configured with Private endpoints (B): While shared ADB instances are configured with private endpoints by default (not publicly accessible), this is not a configurable option you "must" set-it's inherent to shared infrastructure. Thus, it's not a requirement you actively enforce for this scenario; it's already true.
ADB must be configured with NSG (C): Network Security Groups (NSGs) are optional for controlling traffic to an ADB. You can use NSGs for finer-grained security, but they are not mandatory; Security Lists at the subnet level can suffice. Hence, this is not a universal requirement for connectivity.
Cannot connect OCI Marketplace image to shared ADB (D): This is false. OCI Marketplace images (e.g., a web server or analytics tool) can connect to a shared ADB, provided network and authentication prerequisites (like same VCN/subnet and client credentials) are met.
This requirement simplifies network setup and enhances security by keeping communication internal to the VCN. For instance, a Marketplace image like a web application could query an ADB in the same subnet using JDBC or ODBC, leveraging the private endpoint.

NEW QUESTION # 51
Which three are Oracle-recommended best practices for Autonomous Database alarms? (Choose three.)

A. Suppress alarms during investigations
B. Routinely tune your alarms
C. Select the correct alarm interval for your metric.
D. Create multiple alarm metrics

Answer: A,B,C

Explanation:
Oracle recommends best practices for effective alarm management:
Correct Answer (A): Suppress alarms during investigations prevents notification overload while troubleshooting, focusing attention on the issue.
Correct Answer (C): Select the correct alarm interval for your metric ensures timely alerts without excessive noise (e.g., 1-minute intervals for critical metrics).
Correct Answer (D): Routinely tune your alarms adjusts thresholds and settings to match workload changes, maintaining relevance.
Incorrect Option:
B: Creating multiple alarm metrics isn't explicitly recommended; quality and tuning of alarms matter more than quantity.
These practices optimize monitoring efficiency.

NEW QUESTION # 52
Which two statements are true when running DBMS_CLOUD.COPY_DATA? (Choose two.)

A. The source file will be automatically removed after the DBMS_CLOUD.COPY_DATA procedure finishes successfully.
B. The source files can reside in Oracle Object Storage, Amazon S3 Object Storage, or Azure Blob Storage.
C. The source file can be in either Oracle Standard Storage or Oracle Archive Storage bucket in the Object Store.
D. The target table will be created in Autonomous Database if it does not already exist.
E. A valid credential must be created prior to running the DBMS_CLOUD.COPY_DATA procedure.

Answer: B,E

Explanation:
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.
