Oracle Cloud Database Services 2025 Professional Sample Questions (Q87-Q92):

NEW QUESTION # 87
Oracle NoSQL Database Cloud Service supports operations on data based on keys. Which of the following best describes how data is primarily accessed and retrieved within this model?

A. Data is retrieved by traversing relationships between interconnected nodes in a graph structure.
B. Data is accessed through a predefined schema that dictates how data is organized and queried.
C. Data is accessed using structured query language (SQL) with joins and complex filtering conditions.
D. Data is primarily accessed using the unique key associated with the desired data item.
E. Data is searched based on the content of the values using full-text indexing and complex search queries.

Answer: D

Explanation:
C: Accessing data using the unique key:
* Oracle NoSQL Database Cloud Service follows akey-value data model.
* Data is accessed directly using aunique key, which is highly efficient for lookups.
* The value associated with the key can be simple or complex (e.g., JSON objects).
* Provides fast read and write operations.
Why the other options are incorrect:
* A. SQL with joins:Typical of relational databases, not NoSQL.
* B. Graph traversal:Relevant to graph databases, not key-value stores.
* D. Full-text indexing:Not the primary access method in key-value databases.
* E. Predefined schema:NoSQL databases generally supportschema-lessdata storage.

NEW QUESTION # 88
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 # 89
Which two metrics are available for monitoring within the Performance Hub's Real-Time SQL Monitoring feature in Database Management?

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

Answer: A,D

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 # 90
You need to implement a backup and recovery strategy for your MySQL HeatWave Database System. What is the recommended method for backing up and restoring your HeatWave cluster?

A. Using the OCI Object Storage service for storing manual database dumps.
B. Manually copying the data files from the HeatWave cluster's storage.
C. Using the MySQL Enterprise Backup tool directly on the HeatWave nodes.
D. Relying solely on MySQL replication to another MySQL instance.
E. Utilizing OCI Database backups, which include both the MySQL Database System and the HeatWave cluster.

Answer: E

Explanation:
C: Utilizing OCI Database backups:
* Integrated withOracle Cloud Infrastructure (OCI), providing consistent and complete backups.
* Supports both theMySQL Database System and the HeatWave cluster, ensuring data integrity.
* Automates backup scheduling and retention policies.
* Facilitates easy restoration in case of data loss or corruption.
Why the other options are incorrect:
* A. Manual copying:Prone to errors and lacks consistency.
* B. Manual dumps to Object Storage:Labor-intensive and not automated.
* D. MySQL replication:Suitable for high availability, but not a substitute for regular backups.
* E. MySQL Enterprise Backup on nodes:Complex and not designed for HeatWave's distributed environment.

NEW QUESTION # 91
You are managing an Exadata Database Service (ExaDB) and need to perform a full backup of the database to Oracle Cloud Infrastructure Object Storage using the bkup_api utility. The backup must include all datafiles and control files. Which bkup_api command will achieve this?

A. bkup_api bkup_start --full --dbname=dbname
B. bkup_api bkup_start --datafiles --controlfile --dbname=dbname
C. bkup_api bkup_start --all --dbname=dbname
D. bkup_api bkup_start --dbname=dbname

Answer: A

Explanation:
Full Backup with bkup_api:
The --full flag in thebkup_api commandensures that the backup includesall datafiles and control files. This command is essential for creating acomplete, consistent backupsuitable for recovery purposes.
* The backup is stored inOCI Object Storage, leveraging cloud scalability and redundancy.
* The --dbname parameter specifies which database to back up.
Why the other options are incorrect:
* A:This command may initiate a default backup, not a full one.
* B:Specifying files individually is less efficient than using --full.
* D:The --all option does not necessarily imply a full backup.
