Oracle Cloud Database Services 2025 Professional Sample Questions (Q56-Q61):

NEW QUESTION # 56
Which two requirements must be met before you can create an Exadata Database Service VM Cluster?

A. A Virtual Cloud Network (VCN) with necessary subnets for client access and backups.
B. An Exadata Infrastructure resource must be created first.
C. A configured Exadata Cloud@Customer infrastructure.
D. A valid support identifier (SI) associated with the OCI account.
E. A configured Oracle Cloud Infrastructure (OCI) Vault and Key.

Answer: A,B

Explanation:
* B. VCN and Subnets:Exadata Database Service VM Clusters require a VCN to provide network connectivity for database instances, client access, and backups. Proper subnets are essential for this network setup.
* E. Exadata Infrastructure Resource:Before creating a VM Cluster, an Exadata Infrastructure resource must be provisioned. The VM Cluster resides within this infrastructure.
Why the other options are incorrect:
* A:OCI Vault and Key are used for encryption but not mandatory for VM Cluster creation.
* C:A valid SI is needed for support but not a technical requirement for VM cluster creation.
* D:Exadata Cloud@Customer is a separate service from Exadata Database Service.

NEW QUESTION # 57
What is the MOST appropriate method for patching an Exadata Database Service infrastructure, including both database and storage servers, to maintain the latest security updates and bug fixes?

A. Utilizing the automated patching capabilities provided by the Oracle Cloud Infrastructure (OCI) console or API.
B. Relying on the default OS auto-update features to handle all necessary patching.
C. Manually downloading and applying patches to each individual component.
D. Only patching the database nodes and ignoring the storage servers unless a specific issue arises.

Answer: A

Explanation:
B: Automated Patching via OCI Console/API:
* Oracle Cloud Infrastructure offers automated patching tools specifically designed for Exadata Database Service.
* These tools coordinate patching across database and storage servers, ensuring consistency.
* Features include rolling patching to minimize downtime.
* Automation significantly reduces human error and ensures that both database and storage servers are patched efficiently.
Why the other options are incorrect:
* A. Manual patching:Prone to errors and time-consuming, especially for complex Exadata environments.
* C. Default OS auto-update:Insufficient for comprehensive patching of Exadata components.
* D. Ignoring storage servers:Unsafe and could lead to security vulnerabilities.

NEW QUESTION # 58
Within the context of Exadata Database Service, what does scaling out primarily refer to?

A. Expanding the amount of RAM available to a single database instance.
B. Increasing the CPU core count of a single database server VM.
C. Adding additional database server VMs and storage servers to the Exadata system.
D. Upgrading the version of the Oracle Database software.

Answer: C

Explanation:
Scaling Out:
Scaling out in Exadata means increasing thenumber of database server VMs and storage serversto handle a larger workload. This is achieved byadding more compute nodesand storage cells, allowing the system to distribute database processingacross multiple nodes.
This horizontal scalability is ideal for environments with fluctuating workloads or growing data volumes. It improvesquery performance and fault tolerancesince data and workload are distributed across more hardware resources.
Why the other options are incorrect:
* A:Increasing CPU cores within a single VM is consideredscaling up.
* C:Upgrading the database software version is unrelated to scaling.
* D:Increasing RAM is also a form of scaling up, not scaling out.

NEW QUESTION # 59
Which of the following characteristics is most indicative of a NoSQL database's focus on scalability and availability over strict consistency?

A. Support for complex joins and transactions across multiple tables.
B. Partitioning and replication of data across multiple nodes.
C. Enforcement of strict referential integrity constraints.
D. Reliance on a centralized, single-instance architecture.

Answer: B

Explanation:
C: Partitioning and replication of data across multiple nodes:
* NoSQL databases typically prioritizehorizontal scalabilityby distributing data across multiple nodes.
* Replicationensures data availability even if one node fails.
* This approach leads toeventual consistencyrather than strict ACID compliance.
* The system can continue to operate despite some nodes being offline, maintaining high availability.
Why the other options are incorrect:
* A. Complex joins and transactions:Typical of relational databases prioritizing consistency.
* B. Strict referential integrity:More common in SQL databases requiring ACID transactions.
* D. Centralized architecture:Opposite of scalable, distributed NoSQL models.

NEW QUESTION # 60
When deploying Exadata Database Service, what is the PRIMARY benefit of using the "Cloud Tooling" deployment option versus manually configuring an on-premises Exadata system?

A. "Cloud Tooling" automates the provisioning, patching, and lifecycle management of the Exadata infrastructure.
B. "Cloud Tooling" allows using older versions of Oracle Database that are no longer supported on- premises.
C. "Cloud Tooling" completely eliminates the need for any database administrator intervention.
D. "Cloud Tooling" offers significantly more granular control over the underlying hardware configuration.

Answer: A

Explanation:
B: Automation of provisioning and management:
* Cloud Tooling automates key tasks such asprovisioning, patching, scaling, and maintenance.
* Reduces manual configuration errors and saves time.
* Ensures consistency in setup and updates, minimizing downtime.
* Greatly simplifies lifecycle management, making cloud deployments more efficient than on-premises.
Why the other options are incorrect:
* A. More granular hardware control:Cloud tooling abstracts low-level hardware management.
* C. No DBA intervention:While reduced, DBAs still handle application-specific configurations and performance tuning.
* D. Using older database versions:Exadata Cloud Service supportsonly supported versions, not deprecated ones.
