A financial services company is modernizing its payment processing gateway using a microservices architecture on Oracle Kubernetes Engine (OKE). To comply with security policies, all inter-service communication within the cluster must be encrypted, and traffic routing rules for A/B testing must be centrally managed without altering application code. Which OCI service should be integrated with OKE to meet these specific requirements?
A development team is building an event-driven application where a producer service running on a VM needs to send messages to multiple independent consumer services. One consumer handles data archiving, another performs real-time analytics, and a third triggers alerts. Each consumer service must process every message independently and at its own pace. Which OCI serverless technology is best suited for this fan-out messaging pattern?
A developer is tasked with securing a containerized application deployed on OKE. The application requires access to a database password, an API key for a third-party service, and a TLS private key for its web server. According to OCI best practices for managing sensitive information, which TWO actions should be taken? (Select TWO)
A developer has deployed a critical microservice to an OKE cluster. They need to create an automated alert that triggers if the average CPU utilization across all pods in the deployment exceeds 80% for a continuous 5-minute period. Which OCI service should be used to configure this specific alerting rule?
True or False: The 12-Factor App methodology advocates for storing configuration, including credentials and environment-specific settings, directly in the application's codebase to ensure consistency across all deployments.
A developer is writing a Dockerfile for a Java application. To minimize the final image size and improve security, they want to build the application using a full JDK image and then copy only the resulting JAR file into a lightweight JRE-only image for production. Which Docker feature enables this process within a single Dockerfile?
A team is designing an OCI Function that will be triggered by an HTTP request via an API Gateway. The function needs to perform a long-running data processing task that can take up to 10 minutes. What is a critical consideration for this design?
A developer needs to create a CI/CD pipeline that automatically builds a Docker image from source code in a Git repository and pushes the new image to Oracle Cloud Infrastructure Registry (OCIR). Which command is used to upload the locally built and tagged image `my-app:v1.1` to a repository in the `us-ashburn-1` region for the tenancy `mytenancy`?
A retail company is building a serverless application to process new inventory updates. Whenever a JSON file is uploaded to a specific OCI Object Storage bucket, an OCI Function must be triggered to parse the file and update a database. What is the most direct and efficient way to configure this trigger mechanism?
A developer is troubleshooting a failing pod in an OKE cluster. The pod's status is `CrashLoopBackOff`. The developer has already checked the application configuration and resource limits, which appear correct. What is the most effective `kubectl` command to get detailed information about why the container inside the pod is failing to start?
