Oracle AI Cloud Database Services 2025 Professional Practice Exam 2025: Latest Questions

You are designing an Oracle Cloud database deployment where the application must survive a database server failure with minimal downtime and without changing application connection strings. Which Oracle Cloud Database Service architecture best meets this requirement?

A data science team wants to train a model using database-resident data and minimize data movement. They also want to apply the model in SQL queries for scoring. Which approach best aligns with these requirements?

An administrator needs a managed way to create a new cloud database and ensure it is automatically backed up without building custom scripts. Which is the most appropriate action during provisioning?

A security team wants to reduce the risk of exposing database credentials in application configuration files. Which approach is most appropriate in Oracle Cloud deployments?

A retailer is building a search feature that must perform semantic similarity searches over product descriptions stored in an Oracle Cloud database. They want to store embeddings in the database and run similarity queries efficiently. What is the best design choice?

A company needs to migrate an on-premises Oracle database to Oracle Cloud with minimal downtime. They also need ongoing replication until cutover. Which approach best meets the requirement?

Your application has unpredictable workload spikes and the database occasionally experiences high CPU utilization. You want early warning and automated detection without constantly logging in to check metrics. Which combination is the most appropriate?

You need to design network access for a database in Oracle Cloud so that only application subnets can connect, while administrative access is controlled and auditable. Which design is most appropriate?

After enabling a vector similarity feature, query latency becomes inconsistent. The SQL uses a similarity function but frequently falls back to full scans. Which action is most likely to provide stable, predictable performance?

A regulated customer requires that database encryption keys be controlled under strict separation of duties, with the ability to audit key usage and rotate keys without re-architecting the application. Which solution best satisfies these requirements in Oracle Cloud?

You are designing a highly available Oracle Database deployment on OCI using a managed database service. The application requires automatic failover to a synchronized standby in a separate Availability Domain and wants the solution to be managed with minimal custom scripting. Which architecture best meets these requirements?

A data science team wants to run model training close to the data stored in Oracle Database to reduce data movement and apply SQL-based feature engineering. Which approach best aligns with this requirement?

An administrator needs to ensure that a newly provisioned database can be recovered to a specific point in time after a user accidentally drops a critical table. Which capability is most directly used to meet this requirement?

A team is integrating OCI Generative AI with Oracle Database to implement retrieval-augmented generation (RAG). They store document embeddings in the database and need efficient similarity search. Which database feature is most appropriate?

You need to provision a database for a multi-tenant SaaS application. Each tenant requires isolation for schema objects and resource controls, while sharing the same database infrastructure for operational efficiency. Which design best fits this goal on Oracle Database services?

A database workload experiences periodic CPU spikes and slower response times. You want to identify the top SQL statements contributing to DB time and determine whether the issue is CPU, I/O, or contention related. Which toolset is most appropriate?

A team deploys an application that uses a database in a private subnet. They need administrators to access the database for maintenance without exposing it to the public internet. Which is the recommended approach?

You are rolling out an ML scoring feature using in-database models. The application team wants scoring to be consistent across environments and deployments while minimizing privilege grants to application schemas. Which approach is a best practice?

A financial services customer must enforce separation of duties: DBAs can manage infrastructure and availability, but must not be able to read sensitive customer data. They also need centralized key management and the ability to rotate keys. Which combination best meets this requirement?

You have a production database that serves both OLTP and analytics. After enabling a vector similarity search feature for RAG, analytics queries begin to starve OLTP during peak hours. You must protect OLTP latency while still allowing analytics and vector search to run. Which solution is most appropriate?

You are designing an OCI database architecture for an application that requires an Oracle-managed service, fast scale-out read performance, and minimal application changes. The application uses JDBC and can tolerate eventual consistency on read replicas. Which approach best meets the requirement?

A data scientist wants to train a model using data stored in an Oracle Database on OCI without exporting data files to object storage. The goal is to minimize data movement and enforce database access controls. Which approach best satisfies this requirement?

You are provisioning an Autonomous Database for a development team. They want to connect from a CI/CD pipeline without embedding database passwords in build scripts. Which is the recommended approach to meet this requirement?

A production Oracle Database service shows intermittent spikes in query latency. AWR reports a sharp increase in 'db file sequential read' waits during the spikes. The workload is mostly OLTP with index lookups. Which action is the best next step to validate the root cause before making changes?

You are implementing an AI-powered application that uses an Oracle Database to store embeddings and perform similarity search. Users must only retrieve results from rows they are authorized to see, even when performing vector similarity queries. Which design best enforces this requirement?
