Oracle Autonomous Database Cloud 2025 Professional Sample Questions (Q41-Q46):NEW QUESTION # 41
Which two statements are correct about Autonomous Data Warehouse on Shared Exadata Infrastructure?
  • A. Oracle Database Result Cache is enabled by default for all SQL statements.
  • B. You have direct access to the database node.
  • C. Compression is enabled by default. Autonomous Data Warehouse uses Hybrid Columnar Compression for all tables by default.
  • D. Parallelism is not enabled by default.
Answer: A,C
Explanation:
Let's evaluate each statement about Autonomous Data Warehouse (ADW) on Shared Exadata Infrastructure:
A . Oracle Database Result Cache is enabled by default for all SQL statements: True. ADW enables the Result Cache by default to improve query performance by storing frequently accessed results in memory.
B . You have direct access to the database node: False. ADW is a fully managed service; users do not have direct access to underlying nodes, which Oracle manages for patching, scaling, and security.
C . Parallelism is not enabled by default: False. Parallelism is enabled by default in ADW to optimize large analytical queries across multiple CPUs.
D . Compression is enabled by default. Autonomous Data Warehouse uses Hybrid Columnar Compression for all tables by default: True. Hybrid Columnar Compression (HCC) is applied automatically to reduce storage and enhance query performance.
Thus, A and D are correct, reflecting ADW's default performance optimizations.

NEW QUESTION # 42
Which predefined role that exists in Autonomous Database includes common privileges that are used by a Data Warehouse developer? (Choose the best answer.)
  • A. ADWC
  • B. ADBDEV
  • C. ADMIN
  • D. DWROLE
Answer: D
Explanation:
Autonomous Database provides predefined roles tailored to specific use cases. The correct answer is:
DWROLE (B): The DWROLE predefined role is designed for Data Warehouse developers. It includes privileges commonly needed for data warehousing tasks, such as creating tables, views, and materialized views, as well as executing analytical queries. This role is optimized for Autonomous Data Warehouse (ADW) workloads.
The incorrect options are:
ADBDEV (A): There is no predefined ADBDEV role in Autonomous Database; this appears to be a fictional or misinterpreted role.
ADMIN (C): The ADMIN role is a superuser role with full database privileges, far exceeding the needs of a typical Data Warehouse developer and not tailored to that specific use case.
ADWC (D): This is not a predefined role; it might be a typo or confusion with ADW (Autonomous Data Warehouse), but no such role exists.
DWROLE is the best fit for a Data Warehouse developer's needs.

NEW QUESTION # 43
What is the correct way to list all files in the default data pump directory?
  • A. Log onto ADW server and issue ls -al on the command line
  • B. By executing SELECT * FROM DBMS_CLOUD.LIST_FILES('DATA_PUMP_DIR');
  • C. By executing SELECT * FROM UTL_FILE.LIST('DATA_PUMP_DIR');
  • D. You cannot list files in the default data pump directory from Autonomous Data Warehouse (ADW)
Answer: B
Explanation:
In Oracle Autonomous Database, the DBMS_CLOUD package provides tools to interact with cloud storage and directory operations, including listing files in the default Data Pump directory (DATA_PUMP_DIR).
Correct Answer (A): The statement SELECT * FROM DBMS_CLOUD.LIST_FILES('DATA_PUMP_DIR'); is the officially supported method to list files in the DATA_PUMP_DIR. This function returns a result set with details about files in the specified directory, tailored for the managed environment of Autonomous Database.
Incorrect Options:
B: This is false; you can list files in DATA_PUMP_DIR using DBMS_CLOUD.LIST_FILES, as it is designed for this purpose in ADW.
C: The UTL_FILE package is not recommended for Autonomous Database due to its limitations in a cloud-managed environment. DBMS_CLOUD is the preferred utility for such operations. Additionally, the syntax UTL_FILE.LIST is incorrect; the proper procedure would be UTL_FILE.FGETATTR or similar, but it's still not applicable here.
D: Autonomous Database is a fully managed service, and users do not have direct command-line access to the underlying server. Commands like ls -al are unavailable as there's no shell access.
This approach ensures secure and efficient file management within the constraints of a serverless cloud database.

NEW QUESTION # 44
Which statement is FALSE about Autonomous Database maintenance on Dedicated Infrastructure?
  • A. Autonomous Exadata Infrastructure maintenance runs are for infrastructure patching (including patching of the Exadata grid infrastructure code and operating systems updates) and includes container database patching.
  • B. Autonomous Exadata Infrastructure maintenance takes place at least once each quarter.
  • C. If a scheduled container database maintenance run cannot take place, Oracle automatically reschedules the container database maintenance for the following quarter.
  • D. You can change your container database maintenance window or reschedule a single container database maintenance run to ensure that your container database maintenance runs follow.
Answer: A
Explanation:
Full Detailed In-Depth Explanation:
Maintenance on dedicated infrastructure:
A: True. You can adjust maintenance windows for container databases.
B: False. Exadata Infrastructure maintenance (e.g., OS, grid patching) is separate from container database patching, which occurs independently.
C: True. Oracle reschedules missed maintenance to the next quarter.
D: True. Infrastructure maintenance occurs quarterly.

NEW QUESTION # 45
Which is NOT needed to manage Oracle Autonomous Database with REST APIs?
  • A. Database ADMIN password
  • B. User's OCID
  • C. Tenancy's OCID
  • D. Fingerprint of the public key
Answer: A
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.
