Oracle Autonomous Database Cloud 2025 Professional Sample Questions (Q88-Q93):

NEW QUESTION # 88
What are two advantages of using Data Pump to migrate your Oracle databases to Autonomous Database? (Choose two.)

  • A. Data Pump is faster to migrate database than using RMAN
  • B. Data Pump is platform-independent - it can migrate Oracle databases running on any platform
  • C. Data Pump can exclude migration of objects like indexes and materialized views that are not needed by Autonomous Database
  • D. Data Pump creates the tablespaces used by your Autonomous Database

Answer: B,C

Explanation:
Oracle Data Pump is a powerful tool for migrating databases to Autonomous Database (ADB). The two correct advantages are:
Data Pump can exclude migration of objects like indexes and materialized views that are not needed by Autonomous Database (C): True. Data Pump's EXCLUDE parameter allows skipping objects like indexes and materialized views during export (e.g., expdp ... EXCLUDE=INDEX,MATERIALIZED_VIEW). In ADB, these objects are often redundant because the database automatically creates and manages them based on workload (e.g., auto-indexing). For example, exporting a schema with EXCLUDE=INDEX from an on-premises database reduces migration overhead, as ADB recreates necessary indexes post-import, optimizing for its managed environment. This flexibility minimizes unnecessary data transfer and speeds up the process.
Data Pump is platform-independent - it can migrate Oracle databases running on any platform (D): True. Data Pump uses a platform-agnostic dump file format (.dmp), enabling migration from any Oracle Database (e.g., on Linux, Windows, or Solaris) to ADB in the cloud. For instance, you could export from an Oracle 12c database on AIX, upload the dump to OCI Object Storage, and import it into ADB using DBMS_CLOUD.COPY_DATA, regardless of endianness or OS differences (handled by Data Pump's conversion). This universality makes it ideal for heterogeneous migrations.
The incorrect options are:
Data Pump is faster to migrate database than using RMAN (A): False. Speed depends on context-RMAN (Recovery Manager) is faster for physical migrations (e.g., restoring backups) of entire databases, especially large ones, due to block-level copying. Data Pump, a logical migration tool, extracts and loads data row-by-row, which can be slower for massive datasets but offers more control (e.g., schema selection). No universal speed advantage exists; it's workload-specific.
Data Pump creates the tablespaces used by your Autonomous Database (B): False. In ADB, tablespaces are fully managed by Oracle (e.g., DATA tablespace), and Data Pump doesn't create them. It imports data into existing, pre-allocated storage, ignoring source tablespace definitions. E.g., a source tablespace USERS is mapped to ADB's default storage, not recreated.
These advantages make Data Pump a versatile, tailored migration solution for ADB.


NEW QUESTION # 89
Which predefined service connection should you use when running lots of high concurrent queries in an Autonomous Database?

  • A. DBNAME_CONCURRENT
  • B. DBNAME_LOW
  • C. DBNAME_HIGH
  • D. DBNAME_MEDIUM

Answer: B

Explanation:
Full Detailed In-Depth Explanation:
Service connections in Autonomous Database:
A . DBNAME_LOW: Optimized for high concurrency with minimal resources per query, ideal for many simultaneous queries.
B . DBNAME_MEDIUM: Balanced concurrency and performance.
C . DBNAME_HIGH: Prioritizes individual query performance, not concurrency.
D . DBNAME_CONCURRENT: Not a valid service name.


NEW QUESTION # 90
Where are the customer-managed encryption keys stored for Autonomous Database on Dedicated Infrastructure?

  • A. In a separate key vault external to the Exadata infrastructure
  • B. Inside the backup of the container database
  • C. Inside the Autonomous Database wallet
  • D. On the Exadata infrastructure where the Autonomous Database Dedicated is hosted

Answer: A

Explanation:
Customer-managed encryption keys enhance security control:
Correct Answer (A): "In a separate key vault external to the Exadata infrastructure" refers to OCI Vault (Key Management Service), where keys are securely stored and managed outside the database infrastructure.
Incorrect Options:
B: The wallet secures connections, not encryption keys.
C: Storing keys on Exadata compromises separation of duties.
D: Backups don't store keys; they're encrypted by keys from the vault.
This separation ensures robust key management.


NEW QUESTION # 91
Which three are use cases for Graph Studio? (Choose three.)

  • A. 3-D modelling
  • B. Facial recognition
  • C. Churn analysis
  • D. Clustering
  • E. Pattern matching

Answer: C,D,E


NEW QUESTION # 92
You are the admin of an Autonomous Database (ADB) instance, and a new developer has requested a new workspace in APEX. What statement describes the step to provide the developer a new workspace in APEX?

  • A. Access the APEX Administrator Services and create the workspace for the developer.
  • B. Create an IDCS user with the APEX role.
  • C. Create a database user with the APEX role.
  • D. Create a new developer account

Answer: A

Explanation:
Oracle APEX (Application Express) in Autonomous Database requires a workspace for development:
Correct Answer (A): "Access the APEX Administrator Services and create the workspace for the developer" is the correct step. As an admin, you log into the APEX Administration Services (via Database Actions or a direct URL), navigate to "Manage Workspaces," and create a new workspace, assigning it to the developer with a schema and credentials.
Incorrect Options:
B: Creating an IDCS (Identity Cloud Service) user with an APEX role manages authentication but doesn't create a workspace.
C: A database user with an APEX role lacks a workspace; it's a prerequisite step, not the solution.
D: "Create a new developer account" is vague and doesn't specify the APEX workspace creation process.
This ensures the developer has a dedicated environment for building applications.
