Oracle AI Database Administration Associate Practice Exam 2025: Latest Questions

An application team wants to run similarity search over product descriptions stored as vectors in Oracle Database. They want minimal schema changes and the ability to use SQL to filter by product category. Which approach best fits this requirement?

A developer wants to model customer orders as JSON documents but also needs strong relational consistency and the ability to query and join using SQL without complex ETL. Which Oracle feature is designed for this use case?

A DBA wants to ensure a newly created user can connect and create objects only within their own schema, following least privilege. Which is the best initial set of privileges/roles to grant?

You want to reduce the blast radius of a workload that may consume excessive CPU and I/O, affecting other applications on the same database. Which Oracle feature is most appropriate to manage this at the database level?

A team is implementing Retrieval-Augmented Generation (RAG) using vectors stored in Oracle Database. They notice that similarity search is slow as the table grows. Which action is most likely to improve vector search performance?

A developer updates data through a JSON Relational Duality view and expects the underlying relational tables to reflect the change immediately and consistently. What property of duality views enables this behavior?

A database is running slower than usual. You need to identify the SQL statements contributing most to DB time during a specific period. Which tool or view is best suited for this analysis?

You are designing a high-level architecture for separating operational workloads from reporting/ETL workloads within the same Oracle database environment. Which approach best aligns with Oracle best practices for workload isolation and manageability?

A RAG pipeline stores embeddings for millions of documents. Users frequently combine similarity search with restrictive filters (for example, tenant_id, region, and document_type). Queries are still slow even after adding a vector index. Which design change is most likely to improve end-to-end query performance?

A security audit requires that highly sensitive columns (for example, national identifiers) are protected so that even users with direct table access cannot view the raw values, while applications can still query using equality matches. Which Oracle approach best satisfies this requirement?

You are deploying an application that must connect to Oracle Database 23ai with the least-privilege model. The app only needs to read from a few tables and run a single stored procedure. Which approach is the best practice?

A developer stores documents as JSON and wants to enforce that each document must include a non-null string field named "customerId". Which is the most appropriate Oracle approach?

An analyst is comparing two vectors stored in the database and wants a similarity score where a higher score means the vectors are more similar. Which metric is most commonly used for this purpose in vector search?

Your team wants to build an application that reads and writes data as JSON documents but also needs relational constraints and SQL performance. Which feature is designed specifically to provide a unified view so that JSON and relational representations stay consistent?

A vector search query is slow. You suspect the database is performing an exhaustive scan over the vector column. What is the most likely missing database object/configuration to improve performance for approximate nearest neighbor search?

A new microservice must authenticate to the database without storing long-lived passwords and must rotate credentials automatically. Which is the most appropriate approach?

A SQL statement suddenly performs much worse after a data load. You need to confirm whether the execution plan changed and identify the new plan’s key operations. Which built-in capability is the most appropriate first step?

You are designing a consolidation strategy. Several teams need isolated environments (separate schemas and resource controls) while sharing the same database instance to reduce operational overhead. Which architecture best fits this requirement?

You must allow users to run ad-hoc analytics on sensitive tables, but data masking must be enforced consistently regardless of the client tool used. The solution must prevent privileged users from bypassing the masking in normal query access paths. Which feature best meets this requirement?

You are building a RAG-style (retrieval-augmented generation) workflow in the database. The requirement is: store embeddings, retrieve top-N semantically similar chunks, and then join those results back to relational metadata (document owner, retention class) for filtering and auditing. Which design best supports this end-to-end requirement with good maintainability?

A developer reports that a query using a SQL/JSON path expression sometimes throws an error when the JSON document has missing or differently-typed fields. The team wants the query to return NULL (or a default) instead of failing, without requiring application-side exception handling. Which approach is the best practice?

A security team requires that all inbound application connections to the database use encrypted network traffic and that user passwords are not sent in clear text over the network. Which configuration most directly addresses this requirement?

You are designing a vector search feature for product recommendations. The application needs both semantic similarity (vector distance) and traditional filtering (price range, availability, category). Which query pattern is the most appropriate in Oracle Database?

After enabling a new JSON Relational Duality view for an order system, users report occasional failures when two sessions update different parts of the same order document at nearly the same time. They want fewer conflicts while still preserving correct results. Which action is most likely to help?

A batch ETL job suddenly becomes much slower after a change. You suspect a plan regression. You need a database-resident way to confirm whether the optimizer plan changed and, if necessary, preserve a known good plan for future executions. What should you use?
