Oracle Cloud Infrastructure 2025 DevOps Professional (1Z0-1109-25)

What you will practice:

Understand the OCI DevOps Service resource model and CI/CD reference flows; map commits to builds, artifacts, and deployments.

• DevOps Service fundamentals and OCI DevOps resource model
• DevOps Project as the logical container for DevOps resources
• DevOps resources: artifacts, build pipelines, deployment pipelines, external connections, triggers, environments
• CI/CD reference flows: commit-driven build and deploy
• Separation of concerns: CI steps vs CD steps (build vs deployment pipelines)
• Environment targeting concepts in OCI DevOps
• Environment targets: Functions application, group of Compute instances, OKE cluster

Tip: After topic practice, do mixed sets under time pressure and review missed questions immediately.

What you will practice:

Work with OCI DevOps Code Repositories and connect external Git providers for integrated CI triggers and traceability.

• OCI DevOps Code Repositories: creating and managing private repositories
• Repository permissions and access patterns (principles and typical tasks)
• External repository integration via external connections
• Connecting GitHub, GitLab, Bitbucket Cloud, and other supported systems
• Operational Git practices for scenario questions
• Branching strategies and protections (main vs feature branches)
• Code review and merge controls (policy intent)
• Commit identification and traceability into CI builds (commit IDs feeding builds)

Tip: After topic practice, do mixed sets under time pressure and review missed questions immediately.

What you will practice:

Design and troubleshoot build pipelines using build stages and build spec files; understand managed build execution.

• Build pipelines define stages for compile, test, and producing deployable outputs
• Build pipeline consumes a commit ID and executes instructions from a build spec file
• Pipeline stages: meaning, ordering, and dependencies
• Managed Build stage concept and common usage
• Interpreting why a pipeline design fails (ordering, prerequisites, artifact mapping)
• Interpreting build outputs, delivery destinations, and triggers to deployment

Tip: After topic practice, do mixed sets under time pressure and review missed questions immediately.

What you will practice:

Version and store build outputs using OCI DevOps artifacts backed by OCIR or Artifact Registry with strong traceability.

• DevOps artifact fundamentals: referencing artifacts in pipeline stages
• Artifact storage backends: OCI Container Registry (OCIR) and Artifact Registry
• Artifact repository organization and access considerations
• Versioning strategy for releases (semantic versioning or build numbers)
• Linking artifacts to build runs and commit IDs (auditability)

Tip: After topic practice, do mixed sets under time pressure and review missed questions immediately.

What you will practice:

Use the Deliver Artifacts stage to map build outputs to DevOps artifacts; apply ordering constraints and multi-output patterns.

• Deliver Artifacts stage purpose and what it produces
• Mapping outputs from Managed Build to DevOps artifact resources
• Stage ordering constraints (Managed Build must precede Deliver Artifacts)
• Mapping multiple build outputs to multiple artifacts (multi-module builds)
• Promoting artifacts across environments (dev to test to prod) while preserving integrity

Tip: After topic practice, do mixed sets under time pressure and review missed questions immediately.

What you will practice:

Build deployment pipelines targeting Compute, OKE, or Functions; design staged rollouts with approvals and rollback logic.

• Environment definitions and targets in OCI DevOps
• Environment targets: Functions, Compute, OKE
• Deployment pipeline architecture and common stage patterns
• Staged deployment patterns (dev to staging to production)
• Approval gates, phased rollout patterns, rollback decision logic
• Artifact-to-environment compatibility checks
• Infrastructure prerequisites: network access, IAM permissions, cluster access

Tip: After topic practice, do mixed sets under time pressure and review missed questions immediately.

What you will practice:

Operate securely on OKE: secrets encryption, Vault-managed keys, and supply chain controls like signed images.

• OKE security and operational fundamentals (cluster security posture)
• Secure cluster design awareness and hardening themes
• Secrets management in OKE (Kubernetes secrets and etcd)
• Encrypting secrets at rest in etcd
• Using OCI Vault master encryption keys for secrets encryption (customer-managed vs Oracle-managed keys)
• Supply chain integrity: enforcing signed images from OCI Registry
• Image source and integrity verification practices

Tip: After topic practice, do mixed sets under time pressure and review missed questions immediately.

What you will practice:

Automate provisioning with OCI Resource Manager using Terraform stacks and jobs; manage variables, state, and drift concepts.

• OCI Resource Manager fundamentals: stacks and jobs
• Terraform configuration and state handling within Resource Manager
• Running jobs: plan, apply, destroy workflows (conceptual)
• Managing variables and outputs for repeatable environments
• Schema documents for easier variable entry and environment reuse
• Dev–staging–prod reuse pattern with consistent IaC
• Operational reliability: drift awareness and drift detection concepts

Tip: After topic practice, do mixed sets under time pressure and review missed questions immediately.

What you will practice:

Apply least privilege for DevOps pipelines and targets; manage keys and secrets with Vault; enforce artifact integrity guardrails.

• DevOps IAM permissions for projects, repos, pipelines, artifacts, and deployments
• Policy patterns to grant minimal required access
• Key management and encryption choices (Vault keys for OKE secrets encryption)
• Assigning master encryption keys to OKE clusters
• Secure artifact and deployment practices
• Enforcing signed container images and integrity verification
• Least-privilege access patterns for pipelines, registries, and deployment targets

Tip: After topic practice, do mixed sets under time pressure and review missed questions immediately.

What you will practice:

Instrument DevOps pipelines with logs, monitoring, and notifications; troubleshoot build, delivery, and deployment failures.

• CI/CD observability in OCI DevOps projects
• Enabling logging, monitoring, and notifications for DevOps resources
• Troubleshooting build failures: stage ordering, build spec, repository configuration
• Troubleshooting delivery failures: incorrect artifact mapping, dependency configuration
• Troubleshooting deployment failures: environment targeting, IAM policy gaps
• Operational runbooks: alerting and notification routing for CI/CD events
• Post-deploy validation: health checks, smoke tests, rollback readiness

Tip: After topic practice, do mixed sets under time pressure and review missed questions immediately.
