QUESTION 23
Which statement accurately describes the patching process for Oracle Grid Infrastructure (GI) and ASM components on a BaseDB VM system when using user-managed patching?

GI and ASM patching is fully automated by Oracle Cloud Infrastructure and requires no user intervention.

The DBA must manually download the GI and ASM patch bundles and apply them using the appropriate patching tools.

GI and ASM patching is integrated with the database patching process and is automatically handled when the database is patched.

Patching GI and ASM components is only required when the operating system of the VM is upgraded.

QUESTION 31
In comparing NoSQL databases with relational databases, what constitutes a fundamental difference in their approach to data relationships?

NoSQL databases universally lack the ability to represent relationships between data elements.

Relational databases primarily rely on foreign keys to define relationships, while NoSQL databases often embed related data within a single document or use application-level links.

NoSQL databases exclusively use foreign keys to establish relationships, similar to relational database models.

Relational databases offer no mechanism for defining relationships between different data sets.

QUESTION 32
Which characteristic is MOST indicative of an Oracle Cloud Infrastructure (OCI) Base Database Service (BaseDB) virtual machine (VM) deployment compared to using Autonomous Database?

Automated patching and upgrades handled by Oracle.

Shared Exadata infrastructure with other tenants for cost optimization.

Direct control over the operating system and database configuration.

Automatic scaling of compute and storage resources based on workload demands.

QUESTION 33
Which technology within the Exadata Database Service provides intelligent data offloading and processing capabilities directly within the storage tier?

Oracle Data Guard

Exadata Smart Scan

Oracle Active Data Guard

Exadata Smart Flash Cache

QUESTION 34
Which two actions must you undertake when configuring the networking to provide network connectivity for a MySQL HeatWave DB System instance?

Ensure the subnet used has a Service Gateway to Oracle Services, such as Object Storage, so that patching can be applied.

Deploy the MySQL HeatWave DB System to a public subnet to allow external connectivity for users.

Create ingress security rules in the VCN security list or Network Security Groups (NSGs) to allow traffic to the MySQL HeatWave DB System.

Configure a dynamic routing gateway for inter-VCN connectivity.

Create egress security rules in the VCN security list or Network Security Groups (NSGs) to block access from the MySQL HeatWave DB System to any outside network.

QUESTION 35
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?

An application requiring complex analytical queries and joins across multiple related datasets.
