Oracle Cloud Database Services 2025 Professional Sample Questions (Q65-Q70):

NEW QUESTION # 65
Which of the following DOES NOT directly contribute to the calculation of provisioned read capacity units (RCUs) required for a NoSQL Database Cloud Service table?

  • A. Complexity of the security roles defined on the table.
  • B. Average record size being read.
  • C. Data consistency requirements.
  • D. Number of reads expected per second.

Answer: A

Explanation:
RCU Calculation:
Read Capacity Units (RCUs) are determined based ondata size (average record size), read frequency (number of reads per second), and consistency level (eventual vs. strong consistency). Complex security roles do not impact the calculation because they do not directly influence the amount of data read or the frequency of access.
Why the other options are correct:
* A:Larger record sizes increase RCU requirements.
* B:Higher read frequency demands more RCUs.
* D:Strong consistency requires more read operations compared to eventual consistency.


NEW QUESTION # 66
Which two prerequisites are required before you can provision a MySQL HeatWave DB system?

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

Answer: B,C

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 # 67
Which BaseDB lifecycle management activity is MOST directly associated with ensuring the continued availability of a database instance during a planned maintenance window?

  • A. Using Oracle Data Guard for a switchover operation.
  • B. Resizing the block volume storage.
  • C. Applying a quarterly security patch.
  • D. Taking a full database backup using RMAN.
  • E. Performing an in-place upgrade of the database software.

Answer: A

Explanation:
C: Using Oracle Data Guard for a switchover operation:
* Aswitchoveris a planned role reversal between the primary and standby databases.
* Zero data loss:Since both databases are synchronized, it minimizes downtime.
* Ideal for planned maintenance:The primary database is switched to the standby, allowing maintenance on the original primary without downtime.
* Data Guard Switchover:
sql
CopyEdit
ALTER DATABASE SWITCHOVER TO standby_db;
Why the other options are incorrect:
* A. Full backup with RMAN:Backup does not ensure availability during maintenance.
* B. In-place upgrade:Typically involves downtime.
* D. Quarterly patch:Patching often requires database restarts, causing downtime.
* E. Resizing block volume:Does not maintain availability if the database requires restarting.


NEW QUESTION # 68
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. Physical Reads
  • C. Number of CPUs on the host
  • D. Database Version

Answer: A,B

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 # 69
Which of the following actions would typically require the highest level of IAM permissions on a NoSQL table within Oracle NoSQL Database Cloud Service?

  • A. Dropping the entire table.
  • B. Performing a simple read operation on a single row.
  • C. Inserting a new row into the table.
  • D. Updating an existing row in the table.

Answer: A

Explanation:
D: Dropping the entire table:
* Deleting a table is adestructive operationthat permanently removes the data.
* Requires the highest level of permissions due to the potential fordata lossand disruption.
* Usually restricted toadministrators or highly privileged users.
Why the other options are incorrect:
* A. Simple read operation:Basic permission, often granted to most users.
* B. Inserting a row:Requires write permissions, but not as critical as table deletion.
* C. Updating a row:Similar to insertion, modifies existing data but does not destroy the table.
