Oracle Cloud Database Services 2025 Professional Sample Questions (Q85-Q90):

NEW QUESTION # 85
During the provisioning of an Oracle Cloud Infrastructure (OCI) Base Database Service (BaseDB) virtual machine (VM), what is the PRIMARY purpose of specifying the database name (DB Name)?

  • A. To select the character set for the operating system.
  • B. To define the hostname for the database server.
  • C. To determine the operating system user account used for database administration.
  • D. To create the initial database instance and its associated files.

Answer: D

Explanation:
Database Name (DB Name):
When provisioning aBaseDB VM, thedatabase nameis used to create the initial instance. It specifies how the database will be identified and helps in creating associated system files, such ascontrol files, redo log files, and datafiles. This name is crucial fordatabase instance managementand connectivity within the OCI environment.
The DB name becomes part of theDB System resource identifierin OCI, which is used in automation and management tasks.
Why the other options are incorrect:
* A:The hostname is specified independently during network configuration.
* B:OS user accounts are configured separately.
* D:The character set is chosen during database configuration, not based on the DB name.


NEW QUESTION # 86
Which two of the following options are valid statements regarding the management of the operating system on a Base Database Service Virtual Machine DB System?

  • A. Customers are responsible for the security and maintenance of the operating system, including applying necessary patches and updates.
  • B. Oracle manages the underlying operating system patching and updates, ensuring the system remains secure and compliant.
  • C. Direct SSH access to the underlying VM is restricted, and all OS-level operations must be performed through the Web Console.
  • D. Customers are responsible for the initial OS installation, but then patching is controlled entirely by Oracle.
  • E. Customers have full root access to the underlying operating system of the Virtual Machine DB System, allowing for customization and installation of custom software.

Answer: A,E


NEW QUESTION # 87
If the provisioned read capacity units (RCUs) are consistently underutilized for a NoSQL Database Cloud Service table, what is the MOST direct consequence?

  • A. Unnecessary cost expenditure.
  • B. Reduced data durability.
  • C. Increased storage efficiency.
  • D. Improved query performance.

Answer: A

Explanation:
C: Unnecessary cost expenditure:
* In Oracle NoSQL Database Cloud Service, you pay for the provisioned RCUs regardless of actual usage.
* Consistently underutilized RCUs mean that you are incurring costs without fully utilizing the allocated resources.
* Proper capacity planning is crucial to optimize costs.
* To reduce expenses, monitor utilization and adjust RCUs accordingly.
Why the other options are incorrect:
* A. Improved query performance:While having adequate RCUs prevents throttling, over-provisioning does not inherently enhance performance.
* B. Increased storage efficiency:Storage is independent of RCUs, which relate to read throughput.
* D. Reduced data durability:Durability is not impacted by underutilized read capacity.


NEW QUESTION # 88
Which two metrics are available for monitoring within the Performance Hub's Real-Time SQL Monitoring feature in Database Management?

  • A. Average Active Sessions
  • B. Database Version
  • C. Physical Reads
  • D. Number of CPUs on the host

Answer: A,C

Explanation:
Performance Hub Real-Time SQL Monitoring:
ThePerformance Hubin Oracle Database Management provides detailed real-time monitoring of SQL queries, including:
* Physical Reads (A):Measures the number of physical I/O operations performed by a SQL statement.
* Average Active Sessions (B):Reflects the number of sessions actively performing database operations, giving insights into workload and bottlenecks.
These metrics help database administratorsanalyze query performanceand detect issues in real-time.
Why the other options are incorrect:
* C:Number of CPUs is a hardware metric, not part of SQL monitoring.
* D:Database version is static information, not a performance metric.


NEW QUESTION # 89
Which of the following is a proactive strategy to avoid encountering table rate limits in Oracle NoSQL Database Cloud Service?

  • A. Carefully designing the table schema and indexes to optimize query performance and minimize the number of read/write operations required.
  • B. Regularly increasing the table's storage capacity to accommodate future growth.
  • C. Consolidating all data into a single large table to simplify management.
  • D. Disabling data encryption to reduce the overhead of read/write operations.

Answer: A

Explanation:
B: Optimizing schema and indexes:
* Efficient schema design reduces the number of read/write operations.
* Proper indexing reduces the need to scan large data volumes, minimizing the number of read capacity units (RCUs) consumed.
* This proactive approach helps stay within the provisioned rate limits, avoiding throttling.
Why the other options are incorrect:
* A. Increasing storage capacity:Does not address the rate of operations, only storage volume.
* C. Disabling encryption:Unwise due to security risks and does not significantly impact rate limits.
* D. Consolidating data into one table:Likely increases the rate of operations, worsening the problem.
