Oracle Cloud Database Services 2025 Professional Sample Questions (Q50-Q55):

NEW QUESTION # 50
What are the two primary dimensions typically governed by table rate limits in Oracle NoSQL Database Cloud Service?

A. Storage capacity and network bandwidth.
B. Number of indexes and query complexity.
C. Read throughput and write throughput.
D. CPU utilization and memory consumption.

Answer: C

Explanation:
Rate Limiting in NoSQL:
In Oracle NoSQL Database Cloud Service, rate limiting primarily controlsread and write throughput. This means defining themaximum number of read and write operations per secondthat a table can handle.
The goal is toprevent a single table from consuming excessive resources, ensuringfair allocationand system stability.
Why the other options are incorrect:
* A:Storage capacity is managed via quotas, not rate limits.
* C:CPU and memory are related to system resources, not table operations.
* D:Indexing and query complexity are managed differently, often via query optimization.

NEW QUESTION # 51
What is the primary processing paradigm employed by the HeatWave query accelerator for analytical workloads?

A. Row-based processing
B. Columnar processing
C. Index-based processing
D. Key-value pair processing
E. Disk-based processing

Answer: B

Explanation:
HeatWave's Processing Model:
HeatWave usescolumnar in-memory processingto optimize analytical workloads. Storing data in columns rather than rows allows HeatWave toprocess large datasets efficiently, reducing the volume of data scanned and improving query performance. This is crucial for OLAP operations that involveaggregating and analyzing data.
Why the other options are incorrect:
* A:Row-based processing is typical for OLTP workloads, not analytical.
* B:HeatWave operates primarily in memory, not disk.
* D:Indexing enhances performance but is not the primary processing paradigm.
* E:Key-value processing is typical in NoSQL databases, not analytical systems.

NEW QUESTION # 52
Oracle NoSQL Database Cloud Service's key-value model is well-suited for certain types of applications.
Which of the following application scenarios would most directly benefit from the key-value data model's characteristics?

A. A financial system requiring strict transactional integrity and complex relationships between accounts and transactions.
B. A content management system needing to enforce a rigid schema for all documents and their metadata.
C. An application requiring complex analytical queries and joins across multiple related datasets.
D. An enterprise resource planning (ERP) system managing intricate relationships between various business entities.
E. A social media platform needing to store and retrieve individual user profiles and their associated data quickly.

Answer: E

Explanation:
B: Social Media Platform:
* Social media applications require quick retrieval of user profiles based on unique IDs.
* The key-value model supports fast lookups and simple data associations, ideal for user-centric data.
* The flexibility of storing user attributes in a single document enhances performance and scalability.
Why the other options are incorrect:
* A. Complex analytical queries:Relational or analytical databases are better suited.
* C. Financial systems:Require ACID compliance and complex joins, not suitable for key-value models.
* D. Content management:Typically requires a more structured approach, better handled by document databases.
* E. ERP systems:Need relational integrity and complex schema support.

NEW QUESTION # 53
What primary security mechanism within Oracle NoSQL Database Cloud Service governs access to individual tables, dictating which users or groups can perform specific actions?

A. Database Vault
B. Identity and Access Management (IAM) policies
C. Virtual Cloud Network (VCN) security lists
D. Transparent Data Encryption (TDE)

Answer: B

Explanation:
IAM Policies:
Oracle NoSQL Database Cloud Service usesOCI IAM policiesto control access to tables. These policies specify who (user or group) can perform what actions (read, write, delete) on specific database resources. This centralized approach allows for granular permission control, supporting the principle ofleast privilege.
IAM policies are configured at theOCI tenancy leveland can be customized to define access based onusers, groups, and dynamic groups. They are essential for maintaining secure data access, especially in multi- tenant environments.
Why the other options are incorrect:
* A:VCN security lists control network traffic, not table-level access.
* C:Database Vault is for fine-grained access control within traditional Oracle Databases, not NoSQL.
* D:TDE handles data encryption, not access management.

NEW QUESTION # 54
Which data formats are directly supported by the HeatWave Lakehouse feature for querying data in object storage?

A. Only JSON files.
B. Only Parquet files.
C. Only CSV (Comma Separated Values) files.
D. CSV, Parquet, and Avro files.
E. Only XML files.

Answer: D

Explanation:
C: CSV, Parquet, and Avro files:
* HeatWave Lakehousecan directly query data stored inOCI Object Storagewithout loading it into MySQL.
* Supports widely-used data formats:
* CSV (Comma Separated Values): Simple, text-based data format.
* Parquet: Columnar storage format optimized for analytical queries.
* Avro: Row-oriented format used for data serialization.
* This versatility allows integrating data from various sources and querying directly.
Why the other options are incorrect:
* A. Only CSV files:HeatWave supports more than just CSV.
* B. Only Parquet files:HeatWave also supports CSV and Avro.
* D. Only JSON files:JSON is not directly supported by HeatWave Lakehouse.
* E. Only XML files:XML is not directly supported.
