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. Chef
- C. Ansible
- D. Jenkins
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.

- B. Resource Manager. In OCI, the "Resource Manager" automates infrastructure provisioning and configuring of OCI resources, such as Compute, Load Balancing, and Database services.
- C. Jenkins. In OCI, Jenkins is an automation tool for configuration management that focuses on automating delivery and management of entire IT infrastructure stacks.
- D. OCI OKE. In OCI, Container Engine for Kubernetes is a configuration management tool that manages enterprise-scale server infrastructure with minimal human intervention using Infrastructure as Code (IaC).
Answer: B
NEW QUESTION # 61
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. 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.
- D. 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.
Answer: C
Explanation:
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:

NEW QUESTION # 62
Your team is responsible for deploying a new version of an application that is being used by your company's finance department. The application is critical to the department's operations, and any downtime could have serious consequences. What is the recommended approach in OCI for creating identical blue-green environments for this scenario?
- A. Use a single Kubernetes cluster with two node pools, one for the blue environment and one for the green environment.
- B. Use two separate Oracle Container Engine for Kubernetes (OKE) clusters to ensure complete separation between environments.
- C. Deploy the application to two separate OCI tenancies to ensure complete isolation be-tween environments.
- D. Use a single OCI region and create two separate Virtual Cloud Networks (VCNs), one for the blue environment and one for the green environment.
Answer: B
Explanation:
Explanation
The recommended approach in OCI for creating identical blue-green environments for deploying a critical application is to use two separate OKE clusters to ensure complete separation between environments. A blue-green environment is a deployment technique that involves creating two identical environments (blue and green) and switching traffic between them after testing. This technique allows you to reduce downtime, minimize risk, and improve user experience. To create blue-green environments in OCI, you can use two separate OKE clusters, one for the blue environment and one for the green environment. Each cluster will have its own set of resources, such as node pools, pods, services, deployments, etc., that are isolated from each other. You can also use OCI Load Balancing service to route traffic between the clusters based on your criteria.

NEW QUESTION # 69
You are a DevOps engineer who has recently joined a new department. You have created 10 Terraform stacks using Oracle Cloud Infrastructure (OCI) Resource Manager. Each stack creates a different set of resources in OCI for your development team. What determines the cost of these Terraform stacks?
- A. The cost depends on the number of lines of text in your Terraform configuration files.
- B. The cost for each stack will be higher for a Pay As You Go subscription than for monthly flex billing.
- C. The cost depends on the length of time it takes to build each resource using these Terraform stacks.
- D. Resource Manager stacks are free but you are charged for the resources they create.
Answer: D
Explanation:
Explanation
The correct answer is: The cost for each stack will be higher for a Pay As You Go subscription than for monthly flex billing. When it comes to the cost of using Terraform stacks created with Oracle Cloud Infrastructure (OCI) Resource Manager, it's important to note that Resource Manager stacks are free to use.
However, you will be charged for the resources that are provisioned by these stacks. The cost of these resources will depend on factors such as the types of resources created, their con-figurations, usage duration, and the pricing model associated with your subscription. The pricing model you choose, such as Pay As You Go or monthly flex billing, will affect the cost of the re-sources provisioned by your Terraform stacks. Pay As You Go typically incurs usage-based charges, where you pay for the actual consumption of resources. Monthly flex billing, on the other hand, provides predictable costs based on fixed monthly commitments. The number of lines of text in your Terraform configuration files or the time it takes to build resources does not directly determine the cost. It's the actual usage and configuration of provisioned resources that impact the cost.

NEW QUESTION # 71
Pods running in your Oracle Container Engine for Kubernetes (OKE) cluster often need to communicate with other pods in the cluster or with services outside the cluster. As the OKE cluster administrator, you have been tasked with configuring permissions to restrict pod-to-pod communications except as explicitly allowed.
Where can you define these permissions?
- A. Network Policies
- B. IAM Policies
- C. RBAC Roles
- D. Security Lists
Answer: A
Explanation:
Explanation
As the OKE cluster administrator, you can define permissions to restrict pod-to-pod communications except as explicitly allowed by using Network Policies. Network Policies are a Kubernetes feature that allows you to define rules for network traffic within the cluster. They provide fine-grained control over ingress (incoming) and egress (outgoing) traffic between pods. By creating Network Policies, you can specify the allowed communication paths between pods based on various criteria such as source and destination pods, namespaces, IP addresses, ports, and protocols. This allows you to enforce security and isolation within your OKE cluster, ensuring that pods can only communicate with authorized pods or services. RBAC Roles and IAM Policies are used to manage access control and permissions for managing and interacting with the cluster itself, but they do not directly control pod-to-pod communications. Security Lists, on the other hand, are associated with VCN (Virtual Cloud Network) resources and control traffic at the subnet level, not at the pod level within the OKE cluster.

NEW QUESTION # 72
A DevOps team has 50 web servers under their preview and they want to patch a server application. Which element of Ansible can be leveraged for this task and how would it help?
- A. A playbook could be leveraged to explain the series of plays and tasks that need to be run per server.
Then, Ansible would connect with and configure each server's infra-structure automatically using YAML. - B. A playbook could be leveraged and executed against the group of web servers, as de-fined in the task list. Then. Ansible would connect to each server and apply the same set of commands.
- C. A playbook could be leveraged to perform ad hoc commands per server. Then. Ansible will automatically communicate with the servers and execute the ad hoc commands in the order defined.
- D. A playbook could be leveraged and executed against the group of web servers, as de-fined in the Inventory. Then, Ansible would connect to each server and apply the same set of configurations.
Answer: D
Explanation:
Explanation
The correct option is: A playbook could be leveraged and executed against the group of web servers, as defined in the Inventory. Then, Ansible would connect to each server and apply the same set of configurations.
In Ansible, a playbook is a YAML file that describes a series of plays and tasks to be executed against a group of hosts. The inventory file defines the group of web servers that need to be patched. By leveraging a playbook, the DevOps team can define the desired configuration or patching tasks once and apply them consistently across all the web servers in the group. An-sible will connect to each server in the inventory and execute the tasks defined in the playbook, ensuring that the desired configurations or patches are applied uniformly. This approach simplifies the management of multiple servers as the same playbook can be executed against the entire group, eliminating the need to manually configure each server individually. It also allows for automation and repeatability, ensuring that the desired changes are applied consistently and efficiently.
NEW QUESTION # 73
You are tasked with creating and managing a microservices-based application using Oracle Cloud Infrastructure Registry (OCIR). Which three statements accurately describe OCIR capabilities?
- A. Docker images and manifest lists (also known as multi-architecture images) can be stored in Oracle Cloud Infrastructure Registry as long as they adhere to Open Container Initiative specifications. Helm charts aren't included.
- B. In each region that is enabled for your tenancy, you are charged for stored images and managed OCIR services.
- C. When intending to push images to the root compartment, creating an empty repository in advance is not strictly necessary.
- D. You can create up to 500 repositories in Oracle Cloud Infrastructure Registry, consuming a maximum of
500 GB in total, in every enabled region of your tenancy. - 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.
Answer: A,D,E
Explanation:
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.

Which cluster option is the best fit for your requirement?
- A. Creating and managing worker nodes using OCI compute instances.
- B. Using Kubernetes cluster add-ons to automate worker node management.
- C. Using OCI OKE managed nodes with cluster autoscalers to eliminate worker node infrastructure management.
- D. Using OCI OKE virtual nodes to eliminate worker node infrastructure management.
Answer: D
Explanation:
Explanation
The cluster option that is the best fit for ensuring reliable operations of Kubernetes at scale while minimizing the operational overhead of managing the worker node infrastructure is using OCI OKE virtual nodes to eliminate worker node infrastructure management. OKE is a fully managed service that allows you to run and manage your Kubernetes cluster on OCI. A Kubernetes cluster consists of a control plane and a set of worker nodes that run your containerized applications. OKE provides a highly available and secure control plane that is managed by Oracle, while you are responsible for managing the worker node infrastructure. However, OKE also supports virtual nodes, which are serverless compute resources that are automatically provisioned and scaled by OCI based on your application workload demands. Virtual nodes eliminate the need for managing worker node infrastructure, such as security patches, updates, scaling, etc. Virtual nodes also offer a serverless Kubernetes experience, where you can focus on developing and deploying your applications without worrying about the underlying infrastructure.
