A reasonable expectation for Configuration Management (CM) as it pertains to applications in the Oracle Cloud Infrastructure (OCI) DevOps process is consistency in performance, function, design, and implementation. Configuration Management ensures that the application's configuration, set-tings, and dependencies are managed consistently across different environments and deployments. It helps maintain the desired state of the application and ensures that it behaves consistently in terms of performance, functionality, design, and implementation. By using CM practices, develop-ers can ensure that the application's configurations and dependencies are accurately managed and deployed, minimizing variations and inconsistencies that could lead to unexpected behavior or per-formance issues. This helps maintain a consistent experience for users and facilitates smooth and reliable operation of the application.
NEW QUESTION # 50
How can customers rotate their master encryption keys in the Oracle Cloud Infra-structure (OCI) Vault service?
- A. Customers can rotate their keys every 30 days. They may enter a service request (SR) to request a rotation sooner than 30 days since the last rotation.
- B. If you import your own key, you cannot rotate the key. You will have to import a new key to rotate.
- C. Customers can rotate their keys by creating a new Key Version.
- D. Customers can only have OCI rotate their keys once a year.
Answer: C
Explanation:
Explanation
The way that customers can rotate their master encryption keys in the OCI Vault service is by creating a new Key Version. A Key Version is an instance of a Vault managed key that has its own unique OCID and metadata. Customers can create a new Key Version for their Vault managed key at any time, which will generate a new encryption key material for that key. Customers can also specify which Key Version they want to use as the current Key Version for encrypting and decrypting secrets.

Your on-premises private cloud environment consists of virtual machines hosting a set of ap-plication servers.
These VMs are currently monitored using a 3rd party monitoring tool for resource metrics such as CPU and Memory utilization and Disk-Write IOPS. You have created a DevOps Project that includes a workflow to migrate these application servers into Oracle Cloud Infrastructure (OCI) compute instances with a few requirements: - Ensure continuous monitoring is enabled, so the current monitored resource metrics are continuously collected and reported. - Monitor the end-to-end deployment pipeline during the migration workflow and notify with email on each execution. - Notify with email for any new OCI Object Storage buckets created after the migration workflow. What should be your recommended solution to achieve these requirements?
- A. Configure OCI Compute agent on on-premises VMs to collect required resource met-rics. Lise OCI Events service to track all deployments (com.oraclecloud.devopsdeploy.createdeployment) with OC!
Notifications service to track and report all changes occurring the target environment. - B. 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.
- 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 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.
Answer: D
Explanation:
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.

- A. Ansible Collection
- B. Compute Jenkins Plug-in
- C. Terraform
- D. Chef Knife Plug-in
- E. OCI Resource Manager
Answer: A,C
Explanation:
Explanation
To use a Kubernetes cluster in your deployment architecture on Oracle Cloud Infrastructure (OCI) with OCI DevOps service, the two recommended tools or services are: Terraform: Terraform is a widely used Infrastructure-as-Code (IaC) tool that allows you to define and manage your infra-structure resources in a declarative way. You can use Terraform to define and provision your Ku-bernetes cluster on OCI, including the necessary networking, compute resources, and container services. Ansible Collection: Ansible is an open-source automation tool that helps with configuration management, application deployment, and orchestration. The Ansible Collection for OCI provides modules and playbooks specifically designed to manage and interact with OCI resources, including Kubernetes clusters. You can use Ansible Collection to automate the deployment and management of your Kubernetes cluster on OCI. The other options mentioned are not directly related to managing Kubernetes clusters on OCI: Compute Jenkins Plug-in: Jenkins is a popular open-source automation server used for Continuous Integration/Continuous Deployment (CI/CD) processes. The Compute Jenkins Plug-in is specific to managing OCI compute resources using Jenkins but does not directly address Kubernetes cluster deployment. Chef Knife Plug-in: Chef is a configuration management tool that helps with managing infrastructure as code. The Chef Knife Plug-in is used to interact with the Chef tool, but it does not directly address Kubernetes cluster deployment on OCI. OCI Resource Manager: OCI Resource Manager is a service that helps you automate the process of deploying infrastructure resources on OCI. While it can be used to manage various OCI resources, including compute instances, it does not specifically focus on Kubernetes cluster deployment.
NEW QUESTION # 58
A developer is managing a collection of servers and wants to update to the newest version of Apache on all of the defined web servers. Which Ansible AdHoc command can you use to achieve this?
- A. $ ansible webservers -m yum -a "name=httpd state=latest"
- B. $ ansible webservers -m service -a "name=httpd state=started"
- C. $ ansible webservers -m service -a "name=httpd state=install"
- D. $ ansible webservers -m yum -a "name=httpd state=new"
Answer: A
Explanation:
Explanation
The correct Ansible AdHoc command to update to the newest version of Apache on all defined web servers is:
$ ansible webservers -m yum -a "name=httpd state=latest" In this command: "ansi-ble" is the command to execute Ansible. "webservers" is the name of the group defined in the inven-tory file that includes all the web servers. "-m yum" specifies the module to use, which in this case is "yum" for package management. "-a" is used to pass arguments to the module. "name=httpd" speci-fies the name of the package to update, in this case,
"httpd" (Apache). "state=latest" instructs Ansi-ble to update the package to the latest version available. By running this command, Ansible will connect to each server in the "webservers" group and use the "yum" module to update the "httpd" package to the latest version.
NEW QUESTION # 59
A company wants to automate the infrastructure and configure OCI resources on OCI DevOps. Which tool should the company use? (Choose the best answer.)
- A. Terraform
- B. Jenkins
- C. Ansible
- D. Chef
Answer: C
Explanation:
Explanation
The company should use Ansible to automate infrastructure and configure OCI resources on OCI DevOps.
Ansible is a popular open-source automation tool that provides a simple and powerful way to automate infrastructure provisioning, configuration management, and application deployments. It uses a declarative language and follows an agentless architecture, making it easy to use and suitable for automating tasks across different environments, including OCI. While Jenkins is a widely used continuous integration and continuous delivery (CI/CD) tool, it is primarily focused on the software development and deployment process rather than infrastructure automation and resource configuration. Terraform is another popular infrastructure-as-code tool that enables the provisioning and man-agement of infrastructure resources. It is well-suited for creating and managing infrastructure re-sources in OCI and other cloud providers. However, in the context of the question, Ansible is specifically mentioned as the tool to use. Chef is a configuration management tool that helps automate the configuration and management of systems and applications. It can be used for infrastructure automation and configuration, but it is not as commonly used for provisioning and managing cloud resources as Ansible or Terraform. Therefore, the best answer for the given scenario is Ansible.

NEW QUESTION # 61
Which two changes to infrastructure with the Oracle Cloud Infrastructure (OCI) Provider for Terraform will NOT result in any resources being destroyed or provisioned? (Choose two.)
- A. changing the image OCID of a compute instance
- B. adding a CIDR block to a VCN
- C. changing the shape of a compute instance
- D. adding a subnet to a VCN
- E. changing the Display Name of a compute instance
Answer: B,D
Explanation:
Explanation
The two changes to infrastructure with the Oracle Cloud Infrastructure (OCI) Provider for Terraform that will not result in any resources being destroyed or provisioned are: Adding a CIDR block to a VCN: This change does not affect any existing resources. It simply expands the IP ad-dress range of the VCN, allowing for the creation of additional subnets within the VCN. Adding a subnet to a VCN: Similar to adding a CIDR block, adding a subnet to a VCN does not affect any existing resources. It defines a new subnet within the VCN's IP address range, allowing for the al-location of resources to that subnet. Changing the image OCID of a compute instance, changing the shape of a compute instance, and changing the Display Name of a compute instance can potentially result in resource destruction and provisioning. These changes may require the creation of new in-stances, reconfiguration of existing instances, or termination of existing instances, depending on the specifics of the changes.
NEW QUESTION # 62
(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. A deployment Dynamic Group was assigned an incorrect OCID for its compartment.
- C. An administrator created the code repository policy in the parent compartment rather than the main working compartment.
- D. A vault secret has an incorrect OCID assigned to it.
Answer: D
Explanation:
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.

- B. Add a stage to apply the Kubernetes manifest to the Kubernetes cluster.
- C. Add a stage to apply the container image to the Kubernetes cluster.
- D. Add a stage to deliver artifacts to an Oracle Cloud Infrastructure (OCI) Artifact Regis-try.
Answer: D
Explanation:
Explanation
When creating stages for an Oracle Kubernetes Engine (OKE) deployment pipeline, you are able to include the following actions within the pipeline stages themselves: Add a stage to apply the Kubernetes manifest to the Kubernetes cluster: This stage allows you to apply the desired Kubernetes manifest files that define the deployment configuration of your application to the OKE cluster. It ensures that the desired state of your application is reflected in the cluster. Add a stage to apply the container image to the Kubernetes cluster: This stage involves deploying the container image of your application to the OKE cluster. It ensures that the latest version of your application's container image is deployed and running in the cluster. Add a stage to deploy incrementally to multiple OKE target environments: This stage allows you to deploy your application incrementally to multiple OKE target environments, such as staging and production. It enables you to control the deployment process and ensure that the application is rolled out smoothly across different environments.
Add a stage to deliver artifacts to an Oracle Cloud Infrastructure (OCI) Artifact Registry: This stage involves delivering the artifacts generated during the build process, such as container images or other artifacts, to the OCI Artifact Registry. The Artifact Registry provides a centralized location for storing and managing artifacts, making them easily accessible for deployment to OKE or other environments. Including these actions within the pipeline stages themselves helps streamline the deployment process and ensures that all necessary steps are included within the automated pipeline, minimizing the need for manual intervention or external processes.
