Actual Oracle 1Z0-1093-25 Exam Questions

Question 1

When provisioning an Exadata Database Service, which two networking components are mandatory?

Correct answer: C, E

C . Private subnet for client network:

Essential for secure access to the databases hosted on the Exadata Database Service instance.

Ensures that client connections are restricted and managed through private IPs.

E . Private subnet for database backups:

Used to securely connect to Oracle Cloud Infrastructure Object Storage for storing backups.

Enables data protection without exposing the backup traffic to the public internet.

Why the other options are incorrect:

A . Public subnet for monitoring: Not required; secure access can be configured through private subnets.

B . Service Gateway: Optional, used for connecting to Oracle services without using the public internet.

D . NAT Gateway: Not mandatory unless specific outbound connectivity is required.

Question 2

When provisioning a new BaseDB VM, which statement BEST describes the relationship between the available Database Versions and the selected Operating System image?

Correct answer: B

B . Only compatible Database Versions are presented:

The provisioning process filters out incompatible combinations, presenting only database versions that match the chosen OS image.

This ensures that the database software can run properly on the selected OS.

This compatibility check prevents deployment failures and ensures system stability.

Why the other options are incorrect:

A . All Database Versions are compatible: Incorrect; some versions are OS-specific.

C . Automatic OS upgrade: OCI does not automatically upgrade the OS for compatibility.

D . Database version determines OS image: The OS image is selected independently, with the system ensuring compatibility.

Question 3

Which statement accurately describes the function of the HeatWave service in relation to a standard MySQL database?

Correct answer: B

HeatWave as a Query Accelerator:

HeatWave enhances the MySQL Database Service by providing an in-memory, massively parallel query accelerator. It is specifically designed to speed up analytical (OLAP) queries, making them run significantly faster compared to using MySQL alone.

The system stores data in a columnar format and processes it in memory, utilizing distributed, parallel processing to achieve high performance.

Unlike traditional MySQL setups, HeatWave can execute complex analytical workloads efficiently.

Why the other options are incorrect:

A: HeatWave is not a standalone database but an extension of MySQL.

C: It is optimized for analytical workloads, not transactional.

D: It is more than just a caching layer; it actively processes queries.

E: HeatWave clusters do not split MySQL instances but enhance query processing.

Question 4

Which two statements are accurate regarding the lifecycle management of an Exadata VM Cluster?

Correct answer: A, E

A: Exadata VM Clusters can be managed independently from the Exadata Infrastructure. This means you can start or stop the cluster without affecting the infrastructure, which provides flexibility for maintenance and performance tuning.

E: The VM Cluster can be terminated without impacting the Exadata Infrastructure. This feature is useful when you want to reassign the infrastructure resources to a new or different cluster.

Why the other options are incorrect:

B: While some adjustments might not need a reboot, core count scaling often requires restarting.

C: Patching the infrastructure and the VM Cluster are separate processes.

D: Changing the infrastructure shape does not automatically adjust VM Cluster resources. Manual reconfiguration is needed.

Question 5

The concept of 'schema-less' in the context of NoSQL databases primarily refers to what?

Correct answer: A

Schema-less in NoSQL:

This means you don't need to define a rigid, fixed structure before data insertion. Each record can have its own structure, allowing flexibility for evolving data models. This is useful for unstructured or semi-structured data.

Why the other options are incorrect:

B: This describes relational databases.

C: This describes the structured nature of SQL databases.

D: While binary formats may be used, schema-less refers to the logical, not physical, structure.
