Explanation

The necessary configuration to provide access to a private repository in OCI Registry (OCIR) from OCI Container Engine for Kubernetes (OKE) is to create a docker-registry secret for OCIR with an identity Auth Token on the cluster and specify the imagePullSecret property in the application deployment manifest. Here ' s the breakdown of the steps: Create a docker-registry secret for OCIR with an identity Auth Token: In order to authenticate with the private repository in OCIR, you need to create a secret in your OKE cluster that contains the necessary credentials. This can be done by generating an identity Auth Token from the OCI Console and creating a secret in the cluster using the kubectl command. Specify the imagePullSecret property in the application deployment manifest: In your application ' s deployment manifest (such as a Kubernetes Deployment or StatefulSet YAML file), you need to include the imagePullSecret property and specify the name of the secret you created in the previous step. This allows the OKE cluster to use the credentials from the secret to pull the docker image from the private repository in OCIR during deployment. By following these steps, you can ensure that your OKE cluster has the necessary access to the private repository in OCIR, and your application can successfully pull the required docker image during deployment.

Explanation

Oracle Cloud Infrastructure (OCI) API Gateway supports various backend-types to handle incoming requests and route them to the appropriate backend service. However, " ORACLE_STREAMS_BACKEND " is not a valid backend-type in OCI API Gateway. " STOCK_RESPONSE_BACKEND " is a valid backend-type that allows you to configure static responses directly in the API Gateway without routing requests to any specific backend service. This can be useful for handling simple requests or returning predefined responses. " HTTP BACKEND " is another valid backend-type that enables routing requests to an HTTP backend service. " ORACLE_FUNCTIONS_BACKEND " is a valid backend-type that allows you to route requests to Oracle Functions, which are serverless functions that can be used to execute specific logic or operations. However, " ORACLE_STREAMS_BACKEND " is not a valid backend-type in OCI API Gateway. The API Gateway does not have native support for Oracle Streams as a backend service. Oracle Streams is a feature of Oracle Database that provides a publish-subscribe mechanism for data replication and distribution within an Oracle Database environment. It is not directly integrated as a backend service in OCI API Gateway.

Oracle provides a dedicated logging-search OCI CLI command group for querying indexed log content. The documented syntax is oci logging-search search-logs, with --search-query, --time-start, and --time-end as the principal parameters required to define the Logging Query Language expression and search interval. The ordinary oci logging command group is used for administration of logs and log groups rather than searching their contents. logging-query is not a valid top-level OCI CLI service group, and --query-string is not the documented search parameter. Therefore, option B exactly matches Oracle ' s current CLI command reference for submitting a programmatic log search across custom or service logs.

OCI Events invokes configured action resources as a managed service rather than by assuming the identity of the human user who created the rule. Oracle ' s Events material documents the service principal cloudEvents and the policy pattern allowing that service to use functions-family. Scoping that permission to the compartment containing the target Function provides the required compartment isolation. A dynamic group is inappropriate because an Events rule is not a Compute instance or workload principal. Granting permissions to oraclefunctions reverses the invocation relationship, while granting a user group broad function-management rights does not authorize the Events runtime itself. Current Oracle documentation additionally represents cross-tenancy delivery using an eventrule principal and FN_INVOCATION; within the source scenario, B is the intended service authorization model.

Explanation

The two true statements for serverless computing and serverless architectures are: Applications running on a FaaS (Functions as a Service) platform: Serverless architectures typically involve running code in the form of functions on a serverless platform. These functions are event-driven and executed in response to specific triggers or events. Serverless function execution is fully managed by a third party: In serverless computing, the cloud provider takes care of the infrastructure management and resource provisioning. The execution of serverless functions is handled automatically by the platform, relieving developers from the responsibility of managing servers or infrastructure. It ' s important to note that long running tasks are not typically suited for serverless architectures due to the event-driven nature of serverless functions. Also, while serverless functions may have state, it is recommended to avoid external storage dependencies and instead leverage stateless functions whenever possible. Additionally, scaling in serverless architectures is typically handled automatically by the platform, rather than being the responsibility of the application DevOps team.

Statement C is invalid because Oracle permits custom metrics to be postedas frequently as every second. The one-minute value applies to the minimum aggregation interval when metric data is subsequently queried, not to the ingestion frequency. Oracle also verifies the remaining statements. PostMetricData requires timestamps to be less than two hours in the past and less than ten minutes in the future. Custom namespaces must not use reserved prefixes such as oci_ or oracle_. The API additionally allows a maximum of 20 dimensions per metric group in a single posting operation. Therefore, interpreting one minute as the minimum interval between raw metric submissions incorrectly confuses ingestion frequency with Monitoring ' s aggregation/query interval. Option C is consequently the NOT valid statement.

DevOps principles directly address automation across the software delivery lifecycle. Oracle describes DevOps as collaboration between development and operations teams aimed at continuous delivery, with automation applied throughout planning, coding, building, testing, releasing, deploying, operating, and monitoring. OCI specifically identifies CI/CD tooling for automating build, test, release, and deployment activities. Containerization provides consistent application packaging, microservices define an architectural decomposition model, and serverless computing removes much of the underlying infrastructure-management responsibility. None of those technologies by itself defines the automated delivery lifecycle requested in the question. Continuous Integration and Continuous Delivery are core DevOps practices that make software changes repeatable, testable, and deployable at high frequency while reducing manual intervention and release risk. Therefore, the correct cloud-native pillar is DevOps Principles.

Oracle Container Registry requires an OCI Auth Token when Docker prompts for the password during docker login. Oracle explicitly documents that the user first generates an auth token under the OCI user profile, then supplies the tenancy namespace and username as the Docker username and the auth token as the password. A Console password is intended for interactive OCI Console authentication and is not the Docker Registry credential. API signing keys authenticate signed OCI API requests used by the CLI, SDKs, and related tools, while Customer Secret Keys are associated with Object Storage compatibility APIs. Consequently, the programmatic credential designed specifically to serve as the Docker Registry password is the OCI Auth Token.

Idle-timeout is the parameter that is used to configure the time period during which an idle function will remain in memory before Oracle Functions removes its container image from memory2. The idle-timeout parameter is specified in seconds and can be set when creating or updating a function2. The default value for idle-timeout is 30 seconds and the maximum value is 900 seconds (15 minutes)2. If a function has the --provisioned-concurrency option enabled, the idle-timeout parameter is ignored and the function instances are always kept in memory3.Verified References: Creating Functions, Provisioned Concurrency

Explanation

The smallest unit of Kubernetes architecture is a Pod. A Pod is a logical grouping of one or more containers that are deployed together on the same host and share the same network namespace, storage, and other resources. It represents the smallest deployable unit in Kubernetes and is used to encapsulate and manage one or more closely related containers. Containers within a Pod are scheduled and deployed together, allowing them to communicate and share resources efficiently.
