Oracle Cloud Database Services 2025 Professional Sample Questions (Q26-Q31):

NEW QUESTION # 26
What role does the Exadata Storage Server Software play within the Exadata Database Service architecture?

A. It manages the virtual machines hosting the database instances.
B. It acts as a load balancer distributing connections across the database instances.
C. It provides the operating system and management software for the database servers.
D. It provides intelligent storage capabilities, including data filtering, compression, and encryption.

Answer: D

Explanation:
C: Intelligent Storage Capabilities:
* The Exadata Storage Server Software enhances data processing at the storage layer.
* Key features include:
* Smart Scan:Offloads SQL processing to storage.
* Compression:Reduces data size and improves I/O efficiency.
* Encryption:Protects data at rest.
* This software significantly boosts database performance by reducing data transfer to the compute nodes.
Why the other options are incorrect:
* A. VM management:Handled by OCI infrastructure.
* B. OS and management software:Not related to Exadata Storage Server Software.
* D. Load balancing:Handled by Oracle RAC or OCI load balancers.

NEW QUESTION # 27
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. Number of rejected write requests due to insufficient WCUs.
B. Number of rejected read requests due to insufficient RCUs.
C. CPU utilization of the compute instances hosting the database.
D. Latency of read and write operations.

Answer: C

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.

NEW QUESTION # 28
When provisioning an Oracle Cloud Infrastructure (OCI) Base Database Service (BaseDB) on a virtual machine (VM), what is a primary factor that distinguishes it from using a Bare Metal database service?

A. The database software binaries are always pre-installed.
B. The underlying hardware is dedicated solely to your instance.
C. The ability to choose your own hypervisor for virtualization.
D. The ability to create multiple database homes on a single server.

Answer: B

Explanation:
Primary Distinction:
The primary difference betweenBaseDB on a VMandBare Metalis how the underlying hardware is allocated:
* BaseDB on VM:The infrastructure issharedamong multiple tenants, using virtualization to isolate instances.
* Bare Metal Database Service:The server'sphysical hardware is dedicatedexclusively to a single tenant, offeringmaximum performance and isolation.
* This exclusive access to hardware in Bare Metal allows forbetter performanceand control compared to VM-based instances.
Why the other options are incorrect:
* A:Binaries are not always pre-installed in both cases; it depends on the configuration.
* B:Oracle handles hypervisor configuration, not the user.
* D:Both VM and Bare Metal allow multiple database homes if configured properly.

NEW QUESTION # 29
Oracle NoSQL Database Cloud Service utilizes a key-value data model. Which of the following statements accurately describes the fundamental structure of data within this model?

A. Each data item is uniquely identified by a key, and the associated value can be any data type or structure.
B. Relationships between data items are explicitly defined through foreign keys and joins.
C. Data is structured in a graph format, representing entities as nodes and relationships as edges.
D. Data is stored as JSON documents with flexible structures, allowing for nested elements.
E. Data is organized into tables with predefined schemas, similar to relational databases.

Answer: A

Explanation:
C: Each data item is uniquely identified by a key, and the associated value can be any data type or structure.
Key-Value Data Model:
* The key-value model is fundamentally based on a simple association between a unique key and its corresponding value.
* The value can be a simple data type (string, number) or a complex structure (like JSON).
* Oracle NoSQL Database Cloud Service uses this model to ensure efficient, scalable data access.
Why the other options are incorrect:
* A. Organized into tables with schemas:This represents a relational database model.
* B. Stored as JSON documents:Although NoSQL can store JSON, the fundamental model is still key- value.
* D. Relationships defined through foreign keys and joins:This is typical of relational databases.
* E. Graph format with nodes and edges:Represents a graph database model, not key-value.

NEW QUESTION # 30
Which two options correctly describe methods for accessing and managing the Exadata Infrastructure?

A. Direct SSH access to the Exadata Infrastructure compute nodes is permitted for customers with root privileges.
B. Exadata Infrastructure management is solely managed by Oracle and is not directly accessible to customers.
C. Customers have direct access to the Exadata storage cells, allowing them to modify storage configurations.
D. The dbcli utility, used for database administration on VM DB Systems, can also be used to manage the Exadata Infrastructure.
E. Management of the Exadata Infrastructure is primarily performed through the Oracle Cloud Infrastructure (OCI) console and APIs.

Answer: B,E

Explanation:
Managing Exadata Infrastructure:
* OCI Console and APIs (B):The primary method for managing Exadata Infrastructure is through the Oracle Cloud Infrastructure Consoleand associated APIs. This includes provisioning, scaling, patching, and monitoring the Exadata environment.
* Oracle-Managed Infrastructure (E):Exadata Infrastructure management is fully handled by Oracle, which means customers do not have direct access to the underlying hardware. This managed approach ensureshigh availability and security.
Why the other options are incorrect:
* A:Customers do not have root access to Exadata compute nodes to ensure security and system integrity.
* C:Thedbcli utilityis designed for VM DB Systems, not Exadata Infrastructure management.
* D:Exadata storage cells are managed by Oracle, and customers cannot directly modify storage configurations.
