Oracle Autonomous Database Cloud 2025 Professional Sample Questions (Q120-Q125):

NEW QUESTION # 120
Which statement is true when connecting an OCI Marketplace image to a shared Autonomous Database?

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

Answer: C

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 # 121
A new Python developer has joined your team and needs to access the Autonomous Database dat a. How does the developer connect to and interact with the Autonomous Database from Python?

A. By using JDBC Driver
B. By using Oracle Client and the cx_Oracle interface
C. By using Oracle Client and the DBD-oracle interface
D. By using SQL Developer

Answer: B

Explanation:
Python developers connect to Autonomous Database using a dedicated library:
Correct Answer (D): "By using Oracle Client and the cx_Oracle interface" (now renamed oracledb) is the recommended method. The Oracle Client provides the underlying connectivity, and cx_Oracle (or oracledb) is a Python module for database access, supporting wallet-based authentication to Autonomous Database.
Incorrect Options:
A: SQL Developer is a GUI tool, not a Python interface.
B: DBD-oracle is not a standard Python library for Oracle; it's likely a typo or confusion with Perl's DBI.
C: JDBC is for Java, not Python; it's incompatible without a bridge like JPype.
This method ensures efficient, secure Python integration.

NEW QUESTION # 122
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. 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.
C. Use a REST call to enable Auto Scaling.
D. Click Scale Up/Down and select the Auto Scaling checkbox.

Answer: C,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 # 123
When you are increasing the number of OCPUs in your Autonomous Database, what does its status show?

A. SCALING IN PROGRESS
B. UPLIFT IN PROGRESS
C. RESIZING IN PROGRESS
D. UPSCALE IN PROGRESS

Answer: A

Explanation:
Scaling OCPUs in an Autonomous Database triggers a specific status update. The correct answer is:
SCALING IN PROGRESS (D): When you increase (or decrease) the number of OCPUs, the database status in the OCI console changes to "SCALING IN PROGRESS." This indicates that the system is actively adjusting the compute resources, a process that typically completes in a few minutes with no downtime for active transactions.
The incorrect options are:
UPSCALE IN PROGRESS (A): "Upscale" is not an official status term used by Oracle for this operation.
RESIZING IN PROGRESS (B): While "resizing" might intuitively fit, Oracle specifically uses "SCALING IN PROGRESS" for CPU adjustments.
UPLIFT IN PROGRESS (C): "Uplift" is not a recognized status in the context of Autonomous Database scaling.
This status reflects Oracle's terminology for dynamic scaling.

NEW QUESTION # 124
During the provisioning of an Autonomous Database on dedicated hardware, what should the database administrator select to determine where the Autonomous Database is created on the dedicated infrastructure?

A. The Client Credentials wallet, which is used to connect to the Autonomous Database.
B. The compartment of the dedicated infrastructure because each compartment only runs one dedicated environment.
C. The container database in which the Autonomous instance should run.
D. The Listener endpoint where the Autonomous Database should register on.

Answer: C

Explanation:
Full Detailed In-Depth Explanation:
When provisioning an Autonomous Database (ADB) on dedicated infrastructure, the placement within the infrastructure is critical:
A . Listener endpoint: Incorrect. This is for connectivity, not placement.
B . Client Credentials wallet: Incorrect. This is for secure connections, not determining location.
C . The container database in which the Autonomous instance should run: Correct. On dedicated infrastructure, an Autonomous Container Database (ACD) hosts multiple ADB instances. Selecting the ACD during provisioning determines where the ADB resides, affecting resource allocation and isolation.
D . The compartment: Incorrect. Compartments organize resources in OCI, but multiple ACDs can exist within a compartment, so this doesn't pinpoint the exact location.
Choosing the ACD is a key provisioning step for dedicated deployments.
