Enhanced clusters in Oracle Container Engine for Kubernetes (OKE) provide advanced features such as granular control over cluster add-ons, workload identity, and improved worker node management. They also offer strong security measures and come with a financially-backed service level agreement (SLA) for Kubernetes API server uptime, ensuring higher reliability and support for production workloads.

A deployment pipeline in OCI DevOps is used to automate the deployment of application artifacts to a target environment. It is a sequence of stages that includes steps such as approvals, traffic shifts, manual interventions, and the actual deployment of the artifacts to environments like Kubernetes clusters or compute instances.

By implementing each module as anindependent service/process(which is a core feature ofmicroservices architecture), you can replace, update, or delete services without affecting the rest of the application. This ensuresdeployment independenceand makes it easier to adapt toarchitecture changesor technology upgrades without major disruptions.

Microservices architectureallows each service to be built with the best-suited technology stack for its specific function. Thisflexibilityensures that you are not tied to a single technology for the entire application, making future technology upgrades easier and eliminatinglong-term technology commitments.

The Kubernetes Master nodeis thecentral control planeresponsible for managing the cluster’s resources and orchestrating workload deployment. Its primary responsibilities include:

Scheduling: Deciding which workloads (pods) should run on which worker nodes, based on resource availability and scheduling constraints.

ResourceAllocation: Allocating resources to workloads to ensure optimal utilization across nodes.

Cluster Management: Maintaining the desired state of applications, managing cluster events, and ensuring that all the components of the cluster are functioning properly.

Terraform variables are used to define input values for Terraform configurations. They allow users to customize infrastructure deployments by providing different values without modifying the configuration files themselves. Variables help in creating reusable infrastructure code, making it easy to maintain and adjust the infrastructure setup according to different environments or needs.

Build pipelines in OCI DevOps are responsible for defining the stages involved in compiling, testing, and running software applications. These pipelines automate the process of building the code, running unit tests, scanning for vulnerabilities, and packaging the software, all of which occur before deploying the application.

To authenticate with the Oracle Cloud Infrastructure Registry (Container Registry) when using the Docker CLI, you need to use an Auth Token. The Auth Token is created in the OCI console and acts as a password for the Docker login command, providing secure access to the container registry.

Oracle Cloud Infrastructure (OCI) Events Serviceallows you to createrulesto automatically respond to changes in your OCI environment. To create a rule, you need the following items:

Rule Conditions:Conditions define theeventsthat will trigger the rule. This specifies what event (e.g., instance creation, object storage bucket modification) will trigger an action.

Actions:Actions define what should happen when aconditionis met. For example, the action might be to trigger anOCI Functionorsend a notification.

When a deployment stage fails in a OCI DevOps Deployment Pipeline, the recommended approach is to roll back to the previous successful version to ensure that the production environment remains in a stable state. This approach minimizes disruption and ensures that your system continues to function properly while the issue with the failed deployment is investigated and fixed.

In Kubernetes clusters created by Oracle Container Engine for Kubernetes (OKE), data in etcd (the key-value store that holds cluster state and configuration data) is encrypted at rest by default using encryption keys managed by Oracle. Oracle manages the encryption using a master encryption key to protect sensitive data.

This statement is false because Container Engine for Kubernetes (OKE) can utilize existing network resources such as Virtual Cloud Networks (VCNs), subnets, security lists, and route tables for the creation of a new cluster. You can either use pre-existing network resources or let OKE create new network resources automatically.

Oracle Cloud Infrastructure Functions is a serverless compute service that supports a consumption-based pricing model. This means that you are only charged for the compute resources when your function is invoked. This is ideal for intermittent, dynamic, and irregular workloads since the company does not need to provision infrastructure in advance, and costs are directly tied to usage.

ansh81vru1zp is the . In Oracle Cloud Infrastructure Registry (OCIR), the tenancy namespace uniquely identifies the tenancy and is used as part of the image path.

iad is the . The region key is the shorthand identifier for the OCI region (iad represents Ashburn region), and it is used in the fully qualified path for images stored in the Oracle Cloud Infrastructure Registry (OCIR).

The Oracle Cloud Infrastructure Logging service has several log categories that users can utilize:

Custom Logs: Users can create their own logs to collect application-specific data.

Audit Logs: These logs contain audit records that provide information about activities performed on resources, generated by OCI Audit service.

Service Logs: These are logs generated by OCI services, providing information about the functioning and performance of the services.

Execution Logs is not a valid log category in OCI Logging. There are no "execution logs" as a defined category for the Logging service.
