Oracle Autonomous Database Cloud 2025 Professional Sample Questions (Q130-Q135):

NEW QUESTION # 130
You see a clock icon in the Status column on the SQL Monitoring tab of Performance Hub. What does it indicate?

A. The SQL statement did not complete either due to an error.
B. The SQL statement completed its execution.
C. The SQL statement is executing.
D. The SQL statement is queued.

Answer: D

Explanation:
The Performance Hub in Autonomous Database provides real-time SQL monitoring with status indicators:
Correct Answer (A): A clock icon in the Status column indicates "The SQL statement is queued." This means the statement is waiting in a queue (e.g., due to resource limits or consumer group settings) and has not yet started executing.
Incorrect Options:
B: An executing statement typically shows a green progress bar or running icon, not a clock.
C: An error would display a red icon or error symbol, often with details in the UI.
D: A completed statement shows a checkmark or similar success indicator.
This visual cue helps identify resource contention or scheduling delays.

NEW QUESTION # 131
Which Oracle package is used to load data to an Autonomous Database from object storage?

A. DBMS_LOAD
B. DBMS_MIGRATE
C. DBMS_RPC
D. DBMS_CLOUD

Answer: D

Explanation:
Loading data into Autonomous Database from object storage (e.g., OCI Object Storage) relies on a specific PL/SQL package. The correct answer is:
DBMS_CLOUD (D): The DBMS_CLOUD package is Oracle's cloud-native tool for interacting with external data sources, including object storage, in Autonomous Database. It provides procedures like DBMS_CLOUD.COPY_DATA to load data from files (e.g., CSV, JSON, Parquet) stored in OCI Object Storage buckets into ADB tables. For example, to load a CSV file sales.csv from a bucket, you'd:
BEGIN
DBMS_CLOUD.CREATE_CREDENTIAL(credential_name => 'OBJ_STORE_CRED', username => 'oci_user', password => 'auth_token'); DBMS_CLOUD.COPY_DATA(table_name => 'SALES', credential_name => 'OBJ_STORE_CRED', file_uri_list => 'https://objectstorage.region.oraclecloud.com/n/namespace/b/bucket/o/sales.csv', format => json_object('type' value 'csv')); END; This package handles authentication (via OCI credentials), file parsing, and data insertion, supporting formats like text, Avro, and ORC. It's integral to ADB's cloud integration, abstracting low-level operations and ensuring security (e.g., via IAM auth).
The incorrect options are:
DBMS_RPC (A): This package doesn't exist in Oracle Database. It might be a typo or confusion with remote procedure calls, unrelated to data loading.
DBMS_LOAD (B): No such package exists. It might confuse with SQL*Loader, but that's a separate utility, not a PL/SQL package, and isn't used directly in ADB for object storage.
DBMS_MIGRATE (C): This doesn't exist either. It might be a misnomer for DBMS_DATAPUMP (for Data Pump), but that's for database migration, not object storage loading.
DBMS_CLOUD is purpose-built for ADB's cloud-first architecture, making data ingestion seamless and efficient.

NEW QUESTION # 132
Which statement is FALSE about setting up compartment quotas?

A. You cannot manage quotas in a compartment unless you belong to a group that has the correct permissions.
B. Compartment quotas use policies that allow allocation of resources with a high level of flexibility.
C. Compartment quotas cannot be set on the root compartment.
D. Quotas set on a parent compartment override quotas set on child compartments.

Answer: C

Explanation:
Compartment quotas in Oracle Cloud Infrastructure (OCI) manage resource allocation:
Correct Answer (D): "Compartment quotas cannot be set on the root compartment" is false. Quotas can be applied to any compartment, including the root compartment, to limit resource usage tenancy-wide. While direct quotas on the root are less common (child compartment quotas are typically used), it's technically possible via OCI policies.
True Statements:
A: Quotas offer flexible resource limits (e.g., OCPUs, storage) via policy statements.
B: Parent compartment quotas take precedence over child quotas, enforcing hierarchical control.
C: Managing quotas requires appropriate IAM permissions (e.g., manage quotas), ensuring security.
This flexibility supports granular resource management across the tenancy.

NEW QUESTION # 133
An Autonomous Database user with an instance wallet has left the company. The user had shared a database user ID with other users when accessing the Autonomous Database. Other than changing the shared user password, what can an administrator do to protect the instance?

A. Rotate the instance wallet and share the new wallet with the remaining users
B. Trust the user who left not to access the database
C. Delete the user
D. Shutdown and restart the instance

Answer: A

Explanation:
Securing an Autonomous Database after a user departs involves:
Correct Answer (C): "Rotate the instance wallet and share the new wallet with the remaining users" invalidates the old wallet's credentials (e.g., certificates in ewallet.p12). Since the wallet secures client connections, rotating it ensures the departed user's access is revoked, even if they retained a copy.
Incorrect Options:
A: Trusting the user is a security risk, not a solution.
B: Deleting the database user ID doesn't address wallet-based access if credentials were shared externally.
D: Shutting down and restarting doesn't revoke wallet access; it's a temporary disruption.
This enhances security beyond password changes.

NEW QUESTION # 134
Which four levels of access can be defined in policies? (Choose four.)

A. Create
B. Read
C. Inspect
D. Use
E. Manage

Answer: B,C,D,E

Explanation:
Oracle Cloud Infrastructure (OCI) Identity and Access Management (IAM) defines four verb levels for policy permissions:
Read (B): Allows viewing resource details without modification (e.g., read autonomous-databases).
Manage (C): Permits full control, including creating, updating, and deleting resources (e.g., manage autonomous-databases).
Inspect (D): Enables listing resources and basic metadata without detailed access (e.g., inspect autonomous-databases).
Use (E): Allows interaction with resources (e.g., connecting to a database) without altering their configuration.
Incorrect Option:
Create (A): "Create" is not a standalone verb; it's part of the manage verb, which includes creation, update, and deletion actions.
These levels provide granular control over resource access in OCI.

NEW QUESTION # 135
