Oracle Cloud Database Services 2025 Professional Sample Questions (Q30-Q35):

NEW QUESTION # 30
When migrating a MySQL instance to MySQL HeatWave, which method generally provides the MINIMAL downtime for large databases?

  • A. Using a third-party ETL tool to extract, transform, and load the data into the HeatWave instance.
  • B. Utilizing MySQL replication to replicate data to the HeatWave instance and then performing a switchover.
  • C. Using mysqldump to create a logical backup and restoring it to the HeatWave instance.
  • D. Copying the data files directly from the source instance to the HeatWave instance.
  • E. Creating a physical backup using MySQL Enterprise Backup and restoring it to the HeatWave instance.

Answer: B

Explanation:
Using MySQL Replication for Minimal Downtime:
Replication allows forreal-time synchronizationbetween the source MySQL instance and theHeatWave instance. Once the replication catches up, performing aswitchoverto the HeatWave instance ensures minimal disruption.
* This method is especially effective forlarge databases, as data is continuouslysynchronized during the migration process.
* The switchover itself incurs minimal downtime as the applications are redirected to the new instance.
Why the other options are incorrect:
* A:mysqldump and restore are time-consuming for large datasets.
* B:Physical backup and restore are faster than logical, but still involve significant downtime.
* D:Direct data file copying is risky and may cause data corruption.
* E:ETL processes are typically slow and prone to data consistency issues.


NEW QUESTION # 31
Which statement best describes the principle of least privilege as it applies to table security management in Oracle NoSQL Database Cloud Service?

  • A. Granting all users full administrative access to all tables to simplify management.
  • B. Encrypting all tables with the highest level of encryption, regardless of the sensitivity of the data.
  • C. Regularly backing up all tables and storing the backups in a publicly accessible location.
  • D. Granting users only the minimum set of permissions required to perform their assigned tasks on specific tables.

Answer: D

Explanation:
Principle of Least Privilege:
The principle of least privilege states that users should only be granted the minimum permissions necessary to perform their tasks. This reduces the risk of accidental or malicious actions that could compromise data integrity or security.
In the context ofOracle NoSQL Database Cloud Service, implementing this principle involves configuring Identity and Access Management (IAM) policiesto precisely define which users or groups can perform specific actions (such as read, write, delete) on particular tables. By limiting access, the system minimizes potential attack vectors and the impact of compromised accounts.
Why the other options are incorrect:
* A:Granting full administrative access violates the least privilege principle and increases security risks.
* C:Encryption is important, but it addresses data confidentiality, not access control.
* D:Backing up data is good practice, but storing backups in a publicly accessible location is insecure.


NEW QUESTION # 32
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 all "list status"
  • C. dcli -g cell_group "list cell attributes name, status, metriccurrent"
  • D. dcli -g dbnodes "list dbnodes"

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 # 33
When enabling Database Management Service for a cloud database, which of the following is typically NOT a configurable parameter specific to the Database Management Service itself?

  • A. The specific metrics that are collected from the database.
  • B. The database version.
  • C. The maximum amount of storage space allocated for collected metrics.
  • D. The frequency at which performance metrics are collected.

Answer: B

Explanation:
D: The database version:
* Thedatabase versionis not configurable through the Database Management Service.
* The version is determined during the database instance provisioning and is independent of the management service.
* The management service can monitor and manage databases of various versions, but it does not control or alter the version itself.
Why the other options are configurable:
* A. Frequency of metric collection:Can be adjusted to balance performance and data granularity.
* B. Specific metrics collected:Can be customized based on monitoring requirements.
* C. Storage space for metrics:Some configurations allow defining the retention and storage capacity for collected data.


NEW QUESTION # 34
When considering autoscaling for provisioned throughput in NoSQL Database Cloud Service, which metric is LEAST relevant for determining when to scale up the capacity units?

  • A. CPU utilization of the compute instances hosting the database.
  • B. Latency of read and write operations.
  • C. Number of rejected read requests due to insufficient RCUs.
  • D. Number of rejected write requests due to insufficient WCUs.

Answer: A

Explanation:
A: CPU utilization of the compute instances hosting the database:
* Autoscaling in NoSQL Database Cloud Service primarily focuses onRCUs (Read Capacity Units)and WCUs (Write Capacity Units).
* The objective is to dynamically adjust capacity based onquery workload, not onCPU utilization.
* Even if CPU usage is high, it might not necessarily indicate that the capacity units are inadequate.
Why the other options are more relevant:
* B. Rejected read requests (RCUs):Direct indicator that read capacity is insufficient, requiring scaling.
* C. Rejected write requests (WCUs):Indicates that the write throughput is inadequate, necessitating scaling.
* D. Latency of read and write operations:Increased latency often points to under-provisioned throughput.
