Oracle Autonomous Database Cloud 2025 Professional Sample Questions (Q148-Q153):

NEW QUESTION # 148
A customer wants to increase the throughput of their inserts. They have discovered that the bottleneck is in the storage I/Os of their environment. What should they do to remove this bottleneck?

A. Remove any non-JSON data from the database.
B. Increase the number of OCPUs allocated to the database.
C. Run the DBMS_CLOUD.INCREASE_THROUGHPUT procedure.
D. Ask Support to migrate their setup to a node without noisy neighbors.

Answer: B

Explanation:
Addressing a storage I/O bottleneck for insert throughput in Autonomous Database involves resource adjustments:
Correct Answer (C): "Increase the number of OCPUs allocated to the database" boosts processing power, which directly improves I/O performance. In Autonomous Database, OCPUs handle both compute and I/O operations; more OCPUs increase the I/O bandwidth, reducing the bottleneck for insert-heavy workloads.
Incorrect Options:
A: Removing non-JSON data may optimize storage use but doesn't directly address I/O throughput for inserts.
B: "Noisy neighbors" is a shared infrastructure concern, but migration isn't a standard solution for I/O bottlenecks and requires Oracle intervention, not user control.
D: There is no DBMS_CLOUD.INCREASE_THROUGHPUT procedure; this is a fabricated option.
Scaling OCPUs is the most effective user-controlled solution.

NEW QUESTION # 149
For someone that is not a service administrator to use SQL Developer Web, what package would you need to use to give them access?

A. SQLDEV_ADMIN.GRANT_SCHEMA
B. ORDS_ADMIN.GRANT_SCHEMA
C. ORDS_PRIV.ENABLE_SCHEMA
D. ORDS_ADMIN.ENABLE_SCHEMA

Answer: D

Explanation:
SQL Developer Web in Autonomous Database relies on Oracle REST Data Services (ORDS) for access. The correct package is:
ORDS_ADMIN.ENABLE_SCHEMA (B): To allow a non-admin user (e.g., ANALYST1) to use SQL Developer Web, the ADMIN user executes ORDS_ADMIN.ENABLE_SCHEMA to enable the schema for ORDS access. This procedure activates the schema for RESTful services, granting privileges like CONNECT and SELECT implicitly for web-based SQL execution. Example:
BEGIN
ORDS_ADMIN.ENABLE_SCHEMA(p_schema => 'ANALYST1');
END;
After this, the user accesses SQL Developer Web via a URL (e.g., https://<adb-host>/ords/analyst1/_sdw), logging in with their database credentials. This is necessary because SQL Developer Web runs on ORDS, and only enabled schemas can interact with it. For instance, an analyst might query SELECT * FROM sales in the web interface post-enablement, without needing full admin rights.
The incorrect options are:
ORDS_ADMIN.GRANT_SCHEMA (A): No such procedure exists in ORDS_ADMIN. Granting is handled via database roles/privileges (e.g., GRANT CONNECT), not a specific ORDS grant function.
ORDS_PRIV.ENABLE_SCHEMA (C): There's no ORDS_PRIV package; this might confuse with ORDS_ADMIN. The correct package is ORDS_ADMIN for schema enablement.
SQLDEV_ADMIN.GRANT_SCHEMA (D): No SQLDEV_ADMIN package exists. SQL Developer Web access is managed through ORDS, not a separate SQL Developer-specific package.
ORDS_ADMIN.ENABLE_SCHEMA is the standard, secure way to enable non-admin access to this tool in ADB.

NEW QUESTION # 150
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. Event
B. Topic
C. Notification
D. Subject

Answer: B

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 # 151
Which three event types are supported for Autonomous Database?

A. Change Compartment Begin
B. Terminate End
C. Update IORM Begin
D. Maintenance Begin
E. Change Autoscaling Configuration Compartment

Answer: A,B,D

Explanation:
Full Detailed In-Depth Explanation:
Supported events:
A: True. Marks the start of maintenance.
B: False. Not a recognized event type.
C: True. Indicates compartment change start.
D: False. IORM updates are internal, not event-tracked.
E: True. Signals termination completion.

NEW QUESTION # 152
Which set of options can be specified when defining the preferred maintenance schedule of the Exadata Infrastructure for Autonomous Database Dedicated?

A. Month of the Year, Week of the Month, Day of the Week, Start Hour
B. Quarter of the Year, Month of the Quarter, Date of the Month, Start Hour
C. Week of the Quarter, Day of the Week, Start Hour
D. Month of the Quarter, Week of the Month, Day of the Week, Start Hour

Answer: D

Explanation:
Defining a maintenance schedule for Dedicated Exadata Infrastructure allows customization:
Correct Answer (B): "Month of the Quarter, Week of the Month, Day of the Week, Start Hour" is the correct set. For example, you can specify "Month 2 of Q1, Week 3, Wednesday, 02:00 AM," aligning with quarterly planning while offering weekly and daily precision.
Incorrect Options:
A: "Quarter of the Year" and "Date of the Month" are less flexible than week-based options and not the standard format.
C: "Month of the Year" skips the quarterly structure used in dedicated maintenance.
D: Omits "Month of the Quarter," reducing granularity.
This flexibility minimizes disruption for dedicated deployments.
