Oracle Cloud Database Services 2025 Professional Sample Questions (Q66-Q71):

NEW QUESTION # 66
You are tasked with checking the status of the Exadata Database Service (ExaDB) components using the dcli utility. You need to gather information about the health and status of the database servers and storage cells across the ExaDB infrastructure. Which dcli command, combined with appropriate commands run across the nodes, will provide the most comprehensive overview?

  • A. dcli -g cell_group "list cell attributes name, status" combined with dcli -g dbnodes "srvctl status database -d dbname"
  • B. dcli -g dbnodes "list dbnodes"
  • C. dcli -g cell_group "list cell attributes name, status, metriccurrent"
  • D. dcli -g all "list status"

Answer: A

Explanation:
A: dcli -g cell_group "list cell attributes name, status" combined with dcli -g dbnodes "srvctl status database -d dbname" dcli Utility:
* dcli(Distributed Command Line Interface) allows you to run commands on multiple nodes simultaneously.
* cell_group: A group configuration file listing all storage cells.
* dbnodes: A group configuration file listing all database nodes.
Commands Explanation:
* dcli -g cell_group "list cell attributes name, status":
* Retrieves the name and current status of each storage cell.
* dcli -g dbnodes "srvctl status database -d dbname":
* Checks the status of the database instances on the compute nodes.
* Combining these commands provides a complete picture of both storage and compute components.
Why the other options are incorrect:
* B. Including metriccurrent:Produces excessive output, not suitable for a quick health check.
* C. Listing dbnodes only:Insufficient as it lacks storage cell status.
* D. dcli -g all "list status":Invalid syntax and lacks specificity.


NEW QUESTION # 67
Which two prerequisites are required before you can provision a MySQL HeatWave DB system?

  • A. A MySQL Enterprise Edition license.
  • B. An OCI Compute instance to act as a client for the MySQL DB system.
  • C. A configured OCI Vault with encryption keys for database security.
  • D. A pre-configured MySQL database dump for initial data loading.
  • E. A Virtual Cloud Network (VCN) with appropriately configured subnets.

Answer: A,E

Explanation:
VCN Requirement (B):
AVirtual Cloud Network (VCN)with appropriate subnets is essential to providenetwork connectivity and isolationfor the HeatWave DB system. It ensures secure data flow within the Oracle Cloud Infrastructure.
License Requirement (E):
Since HeatWave is anenterprise feature, it requires aMySQL Enterprise Edition license.Without this license, the HeatWave functionalities cannot be utilized.
Why the other options are incorrect:
* A:Data loading can be performed post-provisioning.
* C:While encryption can be configured, it is not a prerequisite.
* D:An OCI Compute instance may be used as a client but is not mandatory for provisioning.


NEW QUESTION # 68

  • A. MySQL Enterprise Monitor
  • B. Oracle SQL Developer
  • C. MySQL Shell Upgrade Checker Utility
  • D. Oracle Cloud Advisor
  • E. MySQL Workbench

Answer: C

Explanation:
C: MySQL Shell Upgrade Checker Utility:
* The utility analyzes MySQL instances for compatibility with newer versions, such as MySQL 8.0 used by HeatWave.
* It checks for:
* Syntax differences
* Data type mismatches
* Deprecated features
* The tool outputs a report highlighting issues that may impact migration to HeatWave.
Why the other options are incorrect:
* A. MySQL Enterprise Monitor:Focuses on monitoring performance, not compatibility.
* B. Oracle SQL Developer:Primarily used for database development, not upgrade checks.
* D. Oracle Cloud Advisor:Provides cloud optimization recommendations, not MySQL compatibility checks.
* E. MySQL Workbench:A visual tool for database design and administration, not specifically for upgrade assessment.

* Performance Hub allows users to analyze performance data collected over time.
* ADDM analysis provides insights into performance bottlenecks and recommendations for tuning.
C: Identify blocking sessions that are impacting database performance:
* Performance Hub helps identify active blocking sessions, enabling quick resolution of performance issues.
* It provides real-time and historical data for better troubleshooting.
Why the other options are incorrect:
* B. Modify database parameters:Performance Hub does not have the ability to change database configurations directly.
* D. Upgrade the database:Upgrades are managed through other tools, such as Database Upgrade Assistant (DBUA).


NEW QUESTION # 70
Which two functionalities are provided by the SQL Performance Analyzer (SPA) within Database Management, aiding in cloud database tuning?

Answer: A,D

Explanation:
B: Compare SQL performance before and after changes:
* SPA evaluates the effect of configuration changes, upgrades, or patches on SQL performance.
* Provides insights into whether a change improves or degrades query performance.
C: Generate performance impact reports:
* SPA generates reports summarizing the effects of specific changes on SQL workload performance.
* Helps DBAs make informed decisions before implementing changes in production.
Why the other options are incorrect:
* A. Automatically rewriting SQL:SPA does not modify queries; it only analyzes and compares performance.
* D. Suggesting indexing strategies:SPA evaluates performance impacts, but indexing recommendations are made by the SQL Tuning Advisor.
