A development team leveraging the Oracle Cloud Infrastructure DevOps service is having trouble getting their build pipeline to complete successfully. Which two situations might be the problem? (Choose two.)
- A. They did not export a vault variable in the vaultVariables section of the build_spec.yaml file.
- B. Their build specification file is available in a different directory of their Git repository, and there is no reference to its location.
- C. The build spec.yaml file is in the root directory of their Git repository, and they didn't specify a path to it.
- D. They forgot to export a required variable in the build_spec.yaml file.
- E. Their source code and Kubernetes manifest are in different Git repositories.
正解：A、B
解説：
Explanation
The two situations that might be causing the problem with the build pipeline in the Oracle Cloud Infrastructure DevOps service are: They did not export a vault variable in the vaultVariables section of the build_spec.yaml file. When using vault variables in the build specification file (build_spec.yaml), it is necessary to export the vault variables in the vaultVariables section of the file. If this step is missed, the pipeline may fail due to missing or inaccessible vault variables. Their build specification file is available in a different directory of their Git repository, and there is no reference to its location. The build specification file (build_spec.yaml) should be properly referenced in the pipeline configuration. If the file is located in a different directory than the default location or if its location is not specified correctly in the pipeline configuration, the pipeline may fail to find and execute the build specification, leading to a failure. To resolve these issues, the development team should ensure that they export the required vault variables in the build specification file and correct-ly reference the location of the build specification file in the pipeline configuration.

解説：
Explanation
The two tools that should be used for leveraging OCI DevOps service and including a Kubernetes cluster in the deployment architecture are: Ansible Collection: Ansible is an open-source automation tool that can be used for configuration management, application deployment, and orchestration. The Ansible Collection for OCI provides pre-built Ansible modules specifically designed for managing resources in Oracle Cloud Infrastructure. It enables automation of provisioning and managing OCI resources, including the setup and configuration of a Kubernetes cluster. Terraform Provider: Terraform is an infrastructure as code tool that allows you to define and provision infrastructure re-sources using declarative configuration files. The Terraform Provider for OCI enables you to define and manage OCI resources, including the creation and configuration of a Kubernetes cluster. It pro-vides a consistent and repeatable way to provision and manage infrastructure components. Chef Knife Plug-in and Compute Jenkins Plug-in are not specifically related to managing resources in OCI or deploying a Kubernetes cluster, so they are not the appropriate tools in this scenario.
質問 # 37
As a startup planning to set up your infrastructure on Oracle Cloud Infrastructure (OCI), you must understand the key concepts of OCI Resource Manager. Which best describes a stack in Resource Manager that will assist you to manage infrastructure using the infrastructure-as-code model?
- A. It represents a request to take a Terraform action on a state. It performs the actions that are defined in the configuration file.
- B. It represents a collection of OCI resources created in the Compartment and includes a collection of Terraform files that specify the resources you want to manage with the Resource Manager
- C. It is a group of related resources used to create lightweight and reusable abstractions, so that you can describe your infrastructure in terms of its architecture.
- D. It is the difference between the real-world state of your infrastructure and the last executed Terraform configuration.
正解：B
解説：
Explanation
A stack in Resource Manager is a collection of OCI resources that are created and managed as a single unit in a compartment. A stack includes a collection of Terraform files that specify the resources you want to manage with the Resource Manager, such as compute instances, networks, storage, etc. You can use a stack to apply the infrastructure-as-code model, which allows you to define, provision, and update your infrastructure using configuration files instead of manual processes.

質問 # 38
Why is it important to extract output artifacts from the Oracle Cloud Infrastructure (OCI) DevOps build pipeline and store them in an Artifact Registry repository?
- A. All artifacts are permanently stored in the build pipeline. Extracting just the ones re-quired for deployment tells the deployment pipeline which artifacts to use.
- B. Storing build artifacts in registries helps the deployment pipeline differentiate output artifacts created by the build pipeline from artifacts copied from a Git repository.
- C. Output artifacts aren't permanent. If they are to be used in the Deliver Artifacts stage, they need to be exported as output artifacts to a registry.
- D. Deliver Artifacts is a required stage of the build pipeline, and the entire pipeline won't work if it is not included in order to extract artifacts after the Managed Build stage.
正解：D
解説：
Explanation
This is because output artifacts are temporary files generated by the build process that are needed to deploy an application. Since these artifacts are not permanent, they need to be extracted from the build pipeline and stored in an Artifact Registry repository for easy distribution, versioning, and management. The Deliver Artifacts stage in the build pipeline is responsible for this task, which en-sures that the correct artifacts are used for each deployment. Here is the reference link for more in-formation on Oracle Cloud Infrastructure (OCI) DevOps build pipeline and Artifact Registry: Ref-erence:

- B. The Helm charts must be located in the OCI Container Registry repository for deployment.
- C. The Helm Upgrade options cannot be used to change the configuration of the Helm re-lease.
- D. The values.yaml file is a generic file located in the OCI Container Registry. You must create a reference to this file.
正解：B
解説：
Explanation
The statement that is false about deployment pipeline in OCI DevOps is that using deployment pipeline, you can deploy artifacts to Kubernetes cluster, Instance Group, and OCI Compute Instances. This statement is false because using deployment pipeline, you can deploy artifacts to Kubernetes cluster and Instance Group, but not to OCI Compute Instances. A deployment pipeline is a component of OCI DevOps service that allows you to automate the deployment of your artifacts to various target environments. A target environment is a destination where you want to deploy your artifact, such as a Kubernetes cluster or an Instance Group. An Instance Group is a group of compute instances that share the same configuration and are managed as a single unit. However, OCI DevOps service does not support deploying artifacts directly to individual OCI Compute Instances.

Notifications service to track and report all changes occurring the target environment. - B. Configure OCI Compute agent on OCI compute instances to collect required resource metrics. Use OCI Events and Functions services to track the end-to-end deployment pipeline (com.oraclecloud.devopsdeploy.createdeployment) and creation of new buckets (com.oraclecloud.objectatorage.createbucker Use OCI Notifications and Events services to notify these changes.
- C. Configure both 3rd party monitoring tool and OCI Compute Agent on OCI compute instances to collect required resource metrics. Use OCI Events service (com.oraclecloud.devopsdeploy.createdeployment) with Notifications service to track and notify all changes occurring in the target OCI environment.
- D. Configure OCI Compute agent on on-premises VMs and OCI compute instances to collect required resource metrics. Use OCI Events service to track the end-to-end deployment process (com.oraclecloud.devopsdeploy.createdeployment) and creation of new bucket (com.oraclecloud.objectstorage.createbucket Use OCI Notifications and Events services to notify these changes.
正解：B
解説：
Explanation
The recommended solution to achieve the requirements mentioned would be: Configure OCI Com-pute agent on OCI compute instances to collect the required resource metrics. Use OCI Events and Functions services to track the end-to-end deployment pipeline (com.oraclecloud.devopsdeploy.createdeployment) and the creation of new OCI Object Storage buckets (com.oraclecloud.objectstorage.createbucket). Finally, utilize OCI Notifications and Events services to notify these changes. Explanation: Continuous monitoring with resource metrics: Install and configure the OCI Compute agent on the OCI compute instances to collect the required re-source metrics such as CPU utilization, memory utilization, and disk IOPS. This ensures continuous monitoring of the VMs as they are migrated to OCI. Monitoring the deployment pipeline: Utilize the OCI Events service to track the end-to-end deployment pipeline. Specifically, use the event type
"com.oraclecloud.devopsdeploy.createdeployment" to monitor the deployment process. This allows you to track the progress and status of the migration workflow. Notification for new OCI Object Storage buckets:
Leverage the OCI Notifications service in conjunction with the OCI Events ser-vice. Set up a notification rule to trigger an email notification whenever a new OCI Object Storage bucket is created. Use the event type
"com.oraclecloud.objectstorage.createbucket" to identify the creation of new buckets. By combining the OCI Compute agent, OCI Events service, Functions service, and Notifications service, you can ensure continuous monitoring of resource metrics, track the deployment pipeline, and receive email notifications for any new OCI Object Storage bucket creations during the migration workflow.
質問 # 41
(OPT_MISS) You have just run the managed build stage of an Oracle Cloud Infrastructure (OCI) DevOps Build Pipeline. The pipeline failed, because the code repository could not be accessed. What might the problem be?
- A. More than one code repository was assigned to the DevOps project
- B. An administrator created the code repository policy in the parent compartment rather than the main working compartment.
- C. A vault secret has an incorrect OCID assigned to it.
- D. A deployment Dynamic Group was assigned an incorrect OCID for its compartment.
正解：C
解説：
Explanation
The possible problem that caused the failure of the managed build stage in an Oracle Cloud Infra-structure (OCI) DevOps Build Pipeline could be that a vault secret has an incorrect OCID assigned to it. In the context of the question, the issue is related to the code repository not being accessible. This suggests that there might be a problem with the authentication or credentials used to access the code repository. One possible cause is that a vault secret, which typically stores sensitive information such as credentials or access tokens, has an incorrect OCID (Oracle Cloud Identifier) as-signed to it. If the secret's OCID is incorrect or doesn't match the expected value, it can result in authentication failures and the inability to access the code repository, leading to a pipeline failure. To resolve this issue, the administrator or developer should verify the OCID assigned to the vault secret and ensure it is correct. They should also check the code repository configuration and ensure that the correct credentials are being used to access the repository.

500 GB in total, in every enabled region of your tenancy. - D. When intending to push images to the root compartment, creating an empty repository in advance is not strictly necessary.
- E. Container Registry can be used as a public docker registry, allowing any internet user with the appropriate URL knowledge to pull images from public repositories.
正解：B、C、E
解説：
Explanation
The statements that accurately describe OCIR capabilities are:
* You can create up to 500 repositories in OCI Registry, consuming a maximum of 500 GB in total, in every enabled region of your tenancy. A repository is a collection of related Docker images that share the same name and have different tags. You can use OCI Registry to store and manage your repositories in OCI. You can also use OCI Registry quotas to monitor and control your repository usage.
* Container Registry can be used as a public docker registry, allowing any internet user with the appropriate URL knowledge to pull images from public repositories. A public repository is a repository that does not require authentication to access. You can use OCI Registry to create and manage public repositories by setting the repository visibility to public. You can also use OCI Registry policies to control who can push images to public repositories.
* Docker images and manifest lists (also known as multi-architecture images) can be stored in OCI Registry as long as they adhere to Open Container Initiative specifications. Helm charts aren't included.
A Docker image is a file that contains the executable code and dependencies for a containerized application. A manifest list is a file that contains references to multiple Docker images for different architectures or platforms. OCI Registry supports storing and managing both Docker images and manifest lists that comply with the Open Container Initiative (OCI) specifications. However, OCI Registry does not support storing and managing Helm charts, which are packages of pre-configured Kubernetes resources.

- B. Implement each module as an independent service/process which can be replaced, up-dated, or deleted without disrupting the rest of the application:
- C. Use monolithic approach to as it makes it easier to incrementally adapt to newer technology.
- D. Use monolithic approach, as it allows you to easily redeploy your applications to per-form frequent updates.
- E. Build the application as a single unit and use container technology to deploy it.
- F. Use microservices architecture as it eliminates any long term commitment to a technology stack.
正解：B、F
解説：
Explanation
The two approaches that can be used to build the e-commerce website and achieve deployment in-dependence, easier technology upgrades, and resiliency to architecture changes are: Implement each module as an independent service/process: This approach is aligned with the microservices architecture, where each module or functionality is developed and deployed as a separate service. This al-lows for independent updates, replacements, or deletions of specific modules without disrupting the rest of the application. It provides flexibility, scalability, and easier technology upgrades by enabling the use of different technologies and frameworks for different services. Use microservices architec-ture: Microservices architecture involves breaking down the application into smaller, loosely coupled services that communicate with each other through APIs. This architecture promotes independent deployment of services, making it easier to update or modify specific services without affecting the entire application. It allows for better scalability, fault isolation, and resiliency to architecture changes. The monolithic approach, where the entire application is built as a single unit, is not suitable for achieving the mentioned goals. It can lead to challenges in deployment independence, technology upgrades, and adaptability to newer technologies.
