Oracle Cloud Infrastructure 2026 Data Science Professional (1Z0-1110-26) – Complete Exam Information

Who Should Take This Exam?

This certification is built for hands-on professionals who work with machine learning and cloud data platforms. Here’s who gets the most out of it:

• Data Scientists with 1–3 years of experience who want to prove their OCI skills to employers. If you’re building, training, and evaluating ML models on Oracle Cloud, this is your credential.
• Machine Learning Engineers responsible for deploying and monitoring models in production. This exam validates your MLOps knowledge inside OCI’s ecosystem.
• Cloud Engineers expanding into data science workloads. If you already manage OCI infrastructure and want to move into ML pipelines and Data Science services, this certification bridges that gap.
• Data Engineers working with OCI Data Flow, Spark applications, and data labeling pipelines. Several exam domains map directly to what data engineers do every day.
• AI/ML Architects designing end-to-end machine learning solutions. This cert shows you can translate business problems into OCI-native ML architectures.
• IT Professionals transitioning into cloud data science roles who need a recognized credential to back their skills.

Most candidates have at least one year of hands-on experience with Oracle Cloud Infrastructure before sitting this exam.

Exam Structure

You’ll have 90 minutes to answer 50 questions. That works out to about 1 minute 48 seconds per question: tight but manageable if you’ve done proper practice. Questions are all multiple-choice, but Oracle often includes multi-select items where you must pick two or more correct answers.

Exam Domains and Topic Weights

The following domains and weights come directly from Oracle’s official exam blueprint for the 1Z0-1110-26 exam. You can verify these on the official Oracle exam objectives page.

Domain 1: OCI Data Science – Introduction & Configuration (10%)

This section tests your foundational understanding of the OCI Data Science service and how to set it up correctly.

• Understand OCI Data Science core concepts, architecture, and service overview
• Explain the capabilities of the Accelerated Data Science (ADS) SDK
• Configure a tenancy to support OCI Data Science, including IAM policies and networking

This domain carries a smaller weight, but candidates who skip it often get tripped up on configuration questions elsewhere.

Domain 2: Design and Set Up Data Science Workspace (15%)

Here, you’re expected to know how to build and manage a working Data Science environment inside OCI.

• Create and manage Projects and Notebook Sessions in OCI Data Science
• Create, publish, and manage Conda environments for reproducible workflows
• Use OCI Vault to securely store credentials and API keys
• Configure and manage source code using Code Repositories (Git integration)

This is a practical domain: questions often describe a setup scenario and ask what the right action is.

Domain 3: Implement End-to-End Machine Learning Lifecycle (45%)

This is the largest domain by far, making up nearly half the exam. Spend most of your study time here.

• Describe the full ML Lifecycle from data acquisition to model deployment
• Use different data sources (Object Storage, ADW, MySQL, etc.) to fetch and prepare data
• Explore, clean, visualize, and profile datasets within OCI notebooks
• Train models using OCI Data Science tools and open-source libraries (scikit-learn, TensorFlow, PyTorch)
• Use Oracle AutoML for automated model selection and hyperparameter tuning
• Evaluate model performance and obtain Global & Local Model Explanations using SHAP and related tools
• Manage trained models using the OCI Model Catalog
• Deploy and invoke a cataloged model via OCI Model Deployment
• Integrate OCI Data Science with OCI Generative AI services
• Deploy LangChain applications within OCI Data Science
• Understand Operators (optional advanced topic) and AI Quick Actions

If you’re short on time, this domain is where your study hours give the highest return.

Domain 4: Apply MLOps Practices (20%)

MLOps is increasingly important for production-grade machine learning, and this domain reflects that.

• Understand OCI MLOps architecture patterns and best practices
• Create and manage Jobs for custom training and inference tasks
• Scale Data Science workloads using OCI compute resources
• Configure Autoscaling for Model Deployment inference endpoints
• Monitor models and log predictions using OCI MLOps tools
• Build and automate ML workflows using OCI Data Science Pipelines

Candidates from traditional ML backgrounds who haven’t worked with MLOps tooling tend to find this domain harder than expected.

Domain 5: Use Related OCI Services (10%)

This final domain tests your ability to work with OCI services that feed into data science workflows.

• Create and manage Spark applications using OCI Data Flow within OCI Data Science
• Describe OCI Open Data Service and its available datasets
• Create and export annotated datasets using OCI Data Labeling

Questions here often appear as service-selection scenarios: given a requirement, which OCI service should you use?

Cost and Eligibility

The exam costs $245 USD. Prices may vary by country due to local tax rules. Oracle does not have strict formal prerequisites for this exam, but they recommend hands-on experience with OCI Data Science and completion of the official learning path: Become an OCI Data Science Professional (2026) on MyLearn Oracle.

There are no mandatory training requirements, but candidates without OCI lab experience tend to struggle with the scenario-based questions. Oracle’s retake policy requires a 14-day waiting period after a failed attempt. There are no limits on the number of retakes, but each attempt costs the full exam fee.

Why 1Z0-1110-26 Certification Matters in 2026

The demand for cloud-native machine learning skills has grown faster than most IT certifications can keep up with. Oracle Cloud Infrastructure is now a genuine alternative to AWS and Azure for enterprise ML workloads, and organizations running Oracle databases and enterprise applications are actively migrating their data science pipelines to OCI.

That creates a real skills gap, and certifications like the 1Z0-1110-26 are how companies identify candidates who know OCI Data Science beyond the basics.

In terms of salary, Oracle-certified data science professionals command competitive pay. According to data from Glassdoor and PayScale, data scientists specializing in cloud platforms typically earn between $110,000 and $160,000 per year in the United States, with OCI-specific expertise adding a premium in industries like finance, healthcare, and telecommunications.

Job roles that specifically list OCI Data Science or Oracle Cloud ML experience include:

• Senior Data Scientist (OCI) – $125,000–$150,000 average
• ML Engineer – Oracle Cloud – $120,000–$145,000 average
• Cloud AI/ML Architect – $140,000–$170,000 average

The 2026 version of this exam has also expanded its focus on Generative AI integration and LangChain deployments within OCI: skills that are in high demand as organizations look to build GenAI-powered applications on top of their existing Oracle infrastructure.

If you’re already working with OCI and building ML models, this certification turns your experience into a credential employers recognize. And if you’re transitioning into data science, having an Oracle professional-level cert sets you apart from candidates who only hold associate-level credentials.

Proven Study Strategies for 1Z0-1110-26 Success

1. Start with Domain 3: spend 40% of your total prep time here. With 45% of the exam focused on the ML Lifecycle, this is where the exam is won or lost. Make sure you’re comfortable with the full pipeline: data fetching, preparation, model training, AutoML, evaluation, explanations, catalog, deployment, and GenAI integration.
2. Build a 5-week study plan: Week 1: Domains 1 and 2 (workspace setup, ADS SDK, tenancy config). Weeks 2 and 3: Domain 3 in full depth. Week 4: Domain 4 (MLOps, pipelines, autoscaling). Week 5: Domain 5 and full practice tests.
3. Use PassITExams practice questions as your daily benchmark: After each study session, do 10–15 practice questions from that topic. If you’re scoring below 75% in any domain, go back before moving on.
4. Get hands-on with OCI: Oracle’s free-tier account gives you access to real OCI Data Science resources. Spin up a Notebook Session, train a model, deploy it: even a small project builds the muscle memory that scenario questions test.
5. Review the ADS SDK documentation: The Accelerated Data Science SDK shows up across multiple domains. Knowing what it can and can’t do is worth a few guaranteed correct answers.
6. Pay attention to multi-select questions: Oracle regularly uses “choose TWO” or “choose THREE” formats. Practice recognizing when a scenario needs more than one answer.
7. Time yourself: Run your practice tests with a 90-minute clock. PassITExams includes a built-in timer so you can get comfortable with the real pacing before test day.
8. Don’t ignore Domain 5: Candidates often skip the OCI Open Data Service and Data Labeling topics because they seem straightforward. But 10% is 5 questions, and those can be the difference between passing and retaking.
