OBI

Working knowledge of Oracle BI Enterprise Edition across its layers: the BI Server repository and data modeling, the presentation layer, analyses and dashboards, security, caching and performance, and integration/administration tasks. Expect questions framed around design decisions and their consequences rather than isolated feature definitions.

Yes, the format is multiple choice. Some items ask you to pick the single best answer, others may ask for more than one correct option, so read the stem carefully for wording like "choose all that apply" before committing to a selection.

Oracle publishes the current question count and time limit for each certification, and they change over time. Rather than relying on second-hand figures, check the official Oracle certification page for this exam for the authoritative numbers before you plan your sitting.

Passing scores and exam fees are set and published by Oracle, and they vary by region and delivery method. Consult the official Oracle certification site for the current passing threshold and pricing; do not budget based on figures quoted in forums or older study guides.

Moderately demanding. Candidates with real repository-building experience usually find it manageable; those who have only consumed existing dashboards struggle. The heaviest domain is data modeling, so weakness there is the most common cause of a narrow miss. Hands-on practice closes that gap faster than reading alone.

Start with architecture so the components fit together, then go deep on the BI Server repository and data modeling since that carries the most weight. Move to the presentation layer, then analyses and dashboards, then security, caching and tuning, and finish with integration and administration. Build a small working repository as you go.

Retake rules, waiting periods and any associated fees are governed by Oracle's certification policy and can change. Check your certification record and the official Oracle certification terms for the retake conditions that apply to your attempt rather than assuming a fixed waiting period.

Weak dimensional modeling and misunderstanding of how the BI Server generates and aggregates queries; confusing physical, business model and presentation layer responsibilities; and neglecting security and cache behaviour because they feel peripheral. Candidates who skip hands-on repository work often recognize terminology but cannot predict outcomes.

Strongly recommended. The repository sits on top of physical sources, and questions about join relationships, aggregation, dimensional hierarchies and query federation assume you understand the underlying relational and dimensional concepts. Without that foundation, memorizing tool behaviour will not carry you through.

Oracle certifications are generally aligned to product releases, and content is updated as the platform evolves. Confirm on the official Oracle certification page which version the current exam targets, and make sure your practice environment matches that release so the interface and features you study are the ones being tested.
