Oracle Cloud Infrastructure 2025 DevOps Professional Advanced Practice Exam: Hard Questions 2025

You are designing an OCI DevOps architecture for a regulated enterprise. Repositories must be private, builds must run in a restricted network without public egress, and artifacts must be scanned and retained with immutable history. Developers authenticate with OCI IAM and must not manage long-lived tokens. Which design best satisfies these constraints while keeping the DevOps workflow native to OCI?

A platform team must deploy the same microservice to three OCI regions with independent failure domains. They require (1) a single source of truth for deployment definitions, (2) region-specific overrides (for example, OCIDs, subnet IDs), (3) safe progressive delivery (canary) in each region, and (4) the ability to stop only the failing region without impacting the others. Which OCI DevOps approach best meets these requirements?

A Build Pipeline intermittently fails when pulling dependencies from a private endpoint in the same VCN. Failures occur only when the build is triggered by a DevOps repository commit; manual reruns from the console often succeed. Logs show sporadic DNS resolution timeouts. The build uses a private runner in a private subnet with custom DNS. What is the MOST likely root cause and best corrective action?

Your team is implementing CI for a monorepo containing 40 services. Requirements: (1) only rebuild services impacted by a commit, (2) enforce that any service’s unit tests must pass before merging, (3) produce reproducible builds, and (4) keep pipeline execution time low under high commit frequency. Which design is MOST appropriate using OCI DevOps Build Pipelines?

A CD pipeline deploys to an OKE cluster using a rolling update. During peak traffic, a deployment occasionally succeeds from the pipeline perspective but results in elevated error rates and later auto-scaling thrash. You need the pipeline to automatically detect unhealthy rollouts and abort/rollback before full impact, using signals from the cluster and application. Which solution best fits OCI-native practices?

A Build Pipeline must access secrets for signing artifacts and also pull from a private container registry. Security requires: no secrets in buildspec, rotation without pipeline edits, and least privilege so only this pipeline can read the secrets. What is the MOST secure OCI design?

Your organization standardizes on Terraform for IaC. A team uses OCI DevOps to run Terraform plan/apply. They experience occasional state corruption and locking conflicts when multiple pipeline runs are triggered close together (for example, two merges). They need strong state consistency, lock enforcement, and auditability, without introducing a third-party SaaS. What is the BEST approach?

A Terraform-based pipeline provisions networking and OKE resources. The team wants to guarantee idempotency and prevent partial infrastructure changes when a mid-run failure happens (for example, transient API errors). They also need to support safe rollbacks to the last known-good configuration in a controlled way. Which strategy is MOST appropriate?

A production deployment pipeline uses multiple compartments (network, security, app) with separate admin teams. The pipeline must provision resources across compartments using Terraform and then deploy the application. Security policy forbids granting broad tenancy-wide permissions to the pipeline. Which IAM design best enables cross-compartment automation with least privilege?

After enabling additional observability, an application’s latency improves, but the on-call team is overwhelmed by noisy alerts. Many alerts trigger during deployments and auto-scaling events and resolve quickly. You need to reduce noise while still catching real regressions and deployment-induced incidents. What is the BEST solution using OCI monitoring/logging best practices?
