Oracle Autonomous Database Cloud 2025 Professional Sample Questions (Q84-Q89):

NEW QUESTION # 84
Which two statements are true regarding active transactions when scaling OCPUs in an Autonomous Database? (Choose two.)

A. Scaling can happen while there are active transactions in the database
B. Active transactions continue running unaffected
C. Active transactions are paused
D. Active transactions are terminated and rolled back

Answer: A,B

Explanation:
Scaling OCPUs in Autonomous Database is designed to be seamless. The two true statements are:
Scaling can happen while there are active transactions in the database (B): ADB supports online scaling, meaning you can increase or decrease OCPUs (e.g., from 2 to 4) via the OCI console or CLI (e.g., oci db autonomous-database update --cpu-core-count 4) without stopping the database. Active transactions (e.g., INSERT INTO orders VALUES (...)) continue running during this process. Oracle's architecture ensures the database remains available, adjusting resources in the background. For example, a web app processing orders won't notice the scaling operation starting at 10:00 AM.
Active transactions continue running unaffected (C): During scaling, existing transactions are not interrupted, terminated, or paused. They complete normally, with Oracle managing resource allocation transparently (e.g., shifting CPU usage without killing sessions). For instance, a long-running UPDATE statement started before scaling finishes successfully, leveraging the database's high-availability design. The status shows "SCALING IN PROGRESS," but users experience no downtime.
The incorrect options are:
Active transactions are terminated and rolled back (A): False. Scaling is non-disruptive; transactions aren't killed or rolled back, preserving data integrity and user experience. Termination only occurs during explicit stops or failures, not scaling.
Active transactions are paused (D): False. There's no pausing mechanism during scaling; transactions run continuously, as pausing would disrupt OLTP or analytical workloads, countering ADB's autonomous promise.
This online scaling capability is a key benefit, ensuring uninterrupted service.

NEW QUESTION # 85
You created an Autonomous Database without auto scaling. Which two ways can you enable auto scaling? (Choose two.)

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

Answer: A,B

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 # 86
Which is NOT needed to manage Oracle Autonomous Database with REST APIs?

A. Tenancy's OCID
B. Fingerprint of the public key
C. Database ADMIN password
D. User's OCID

Answer: C

Explanation:
Managing Autonomous Database via REST APIs relies on OCI authentication:
Correct Answer (D): "Database ADMIN password" is not needed. REST API access uses OCI IAM credentials, not database-level credentials like the ADMIN password.
Required Items:
A: User's OCID identifies the API caller.
B: Tenancy's OCID specifies the cloud environment.
C: Fingerprint of the public key authenticates API requests with a private-public key pair.
This ensures secure, external management without exposing database credentials.

NEW QUESTION # 87
Which terminology is used to refer to a communication channel for sending messages to a subscription, such as email or SMS, in Oracle Cloud Infrastructure?

A. Notification
B. Subject
C. Topic
D. Event

Answer: C

Explanation:
In Oracle Cloud Infrastructure (OCI), the Notifications service is used to send messages (e.g., via email, SMS, or HTTP endpoints) to subscribers. The correct terminology for the communication channel is:
Topic (C): A "topic" in OCI Notifications is the named entity that acts as a communication channel. Publishers send messages to a topic, and subscribers (e.g., email addresses, SMS numbers, or custom endpoints) receive those messages based on their subscription to that topic. For example, you might create a topic called "DatabaseAlerts" to send notifications about database events. When a message is published to this topic, all subscribed endpoints (e.g., an email like user@example.com) receive it. This design follows a publish-subscribe (pub/sub) model, making "topic" the central concept for message distribution.
The incorrect options are:
Subject (A): The "subject" is a field within a message (e.g., the subject line of an email), not the channel itself. It describes the content of an individual notification but doesn't define the mechanism for sending it. For instance, an email notification might have a subject like "Database Maintenance Scheduled," but the topic is the channel delivering it.
Notification (B): A "notification" refers to the actual message being sent (the payload), not the channel through which it travels. It's the output of the process, not the infrastructure enabling it. For example, a notification might be "Database is down," but it's sent via a topic.
Event (D): An "event" is an occurrence or trigger (e.g., a database failover) that might generate a notification, but it's not the channel. Events are inputs that can be monitored by services like OCI Events, which then publish to a topic in Notifications.
The use of "topic" aligns with OCI's architecture for scalable, decoupled messaging. To illustrate, you'd create a topic in the OCI console under "Notifications," configure subscriptions (e.g., email or SMS), and then use APIs or triggers to publish messages to it. This abstraction ensures flexibility and reliability in message delivery across various protocols.

NEW QUESTION # 88
What are two differentiators of Oracle Autonomous Database on Dedicated Infrastructure? (Choose two.)

A. Users have SYS privileges in the database.
B. Users have OS access to the database machine.
C. Users can customize the OS stack and add additional packages.
D. Users are offered greater control and isolation starting at the Exadata Cloud Infrastructure level.
E. Users have more control over the maintenance schedule.

Answer: D,E

Explanation:
Autonomous Database on Dedicated Infrastructure offers unique features:
Correct Answer (A): "Users are offered greater control and isolation starting at the Exadata Cloud Infrastructure level" highlights dedicated hardware (compute, storage, network), ensuring isolation and performance not available in shared setups.
Correct Answer (E): "Users have more control over the maintenance schedule" allows scheduling maintenance windows, unlike shared infrastructure's fixed schedules.
Incorrect Options:
B: OS customization is not allowed; Oracle manages the stack fully.
C: No OS access is provided; it's a managed service.
D: SYS privileges are not unique to dedicated infrastructure; they depend on user roles, not deployment type.
These differentiators enhance control and isolation for enterprise needs.
