Oracle Cloud Infrastructure 2023 DevOps Professional Questions and Answers

Question 1

A DevOps engineer is asked to access an Oracle Cloud Infrastructure Container Engine for Kubernetes (OKE) cluster to deploy new applications and manage existing ones. Which three statements are true? (Setting Up Cluster Access). (Choose three.)

Options:

When a cluster's Kubernetes API endpoint has a public IP address, you can access the cluster in Cloud Shell by setting up a kubeconfig file

You cannot setup Cloud shell access to the cluster if the clusters Kubernetes API end-point has a private IP address.

Generating an API signing key pair is a mandatory step while setting up cluster access using local machine if the public key is not already uploaded in the console.

To access the cluster using kubectl you have to set up a Kubernetes configuration file for the cluster. The kubeconfig file by default is named config and stored in the $HOME/.kube directory.

To access the cluster using kubectl you have to set up a Kubernetes manifest file for the cluster. The kubeconfig file by default is named config and stored in the $HOME/.manifest directory

Question 8

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?

Options:

Resource Manager stacks are free but you are charged for the resources they create.

The cost depends on the number of lines of text in your Terraform configuration files.

The cost for each stack will be higher for a Pay As You Go subscription than for monthly flex billing.

The cost depends on the length of time it takes to build each resource using these Terraform stacks.

Question 9

How can customers rotate their master encryption keys in the Oracle Cloud Infra-structure (OCI) Vault service?

Options:

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.

If you import your own key, you cannot rotate the key. You will have to import a new key to rotate.

Customers can rotate their keys by creating a new Key Version.

Customers can only have OCI rotate their keys once a year.

Question 10

Which two are prerequisites for creating a secret in Oracle Cloud Infrastructure Vault service?

Options:

The user must create a compute instance to run the secret service.

When creating a new cluster, essential cluster add-ons are set to manually update.

When enabling a cluster add-on, you cannot configure the add-on by specifying one or more key/value pairs to pass as arguments to the cluster add-on.

Question 12

Which is a proper rule to follow when creating container repositories inside the Oracle Cloud Infrastructure (OCI) Registry?

Options:

When naming a container repository, you may use capital letters but not hyphens. For example, you may use BGdevops-storefront, but not bgdevops/storefront.

When creating a container repository, check the Immutable Artifacts box, as it keeps other developers from altering the files.

You must use a separate container repository for each image, but multiple versions of that image can be in a single repository.

You must use the OCI DevOps Managed Build stage to define artifacts in the artifact and container repositories and map the build pipeline outputs to them.

Question 13

						Question 22					
					
						As a DevOps engineer, you are tasked with patching a server application running on 100 web Servers. How can Ansible help you accomplish this task and which Ansible element should you leverage?
					
					
						Options:
						A. 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.
						B. 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.
						C. 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.
						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 soever and apply the same set of configurations.
						
						
						
					
					
						
						
							Answer:
							D

														Explanation:
							Explanation: To patch a server application running on 100 web servers, you can use Ansible and leverage a playbook. A playbook is a YAML file that defines the desired state of your infrastructure, such as packages, services, files, etc. You can use a playbook to specify the tasks that need to be performed on each server, such as updating the application, restarting the service, etc. You can also execute the playbook against a group of web servers, as defined in the inventory. The inventory is a file that lists the hosts and groups that Ansible can manage. By using a playbook and an inventory, you can automate the patching process and ensure consistency across all servers.

						Which TWO components are optional while creating Monitoring Query Language (MQL) expressions in Oracle Cloud Infrastructure Monitoring service? (Choose two.)
					
					
						Options:
						A. Dimensions
						B. Metric
						C. Grouping Function
						D. Statistic
						E. Interval
						
						
					
					
						
						
							Answer:
							A, C

														Explanation:
							Explanation: Explanation
When creating Monitoring Query Language (MQL) expressions in Oracle Cloud Infrastructure Monitoring service, the optional components are: Dimensions: Dimensions provide additional con-text or filters for the metrics being queried. They allow you to narrow down the scope of the query by specifying specific resources, regions, or other properties. Grouping Function: The grouping function is used to aggregate or group the data based on specified dimensions. It allows you to perform calculations or analysis on a subset of data and present the results in a summarized form. The components that are not optional when creating MQL expressions are: Statistic: The statistic component is mandatory and represents the specific metric or data point you want to retrieve or analyze. It can be a simple statistic like average, sum, count, etc., or a complex expression involving mathematical or logical operations. Metric: The metric component is also mandatory and refers to the specific metric you want to monitor or analyze. It represents the data being collected and reported by the monitoring service, such as CPU utilization, network traffic, or custom metrics. Interval is not a component of MQL expressions. It refers to the time range or period over which the query is executed and is not specified within the MQL expression itself.

						Question 24					
					
						What is the correct approach to upgrade an Oracle Container Engine for Kubernetes (OKE) Cluster to a newer version of Kubernetes?
					
					
						Options:
						A. Initiate the automated upgrade process using the OCI Console. CLI, or API.
						B. Upgrade the node pools one at a time, then once all node pools are upgraded, upgrade the control plane.
						C. Initiate the control plane and node pool upgrades simultaneously.
						D. Upgrade the control plane, then upgrade the node pools.
						
						
						
					
					
						
						
							Answer:
							C

														Explanation:
							Explanation: Explanation
The correct approach to upgrade an Oracle Container Engine for Kubernetes (OKE) cluster to a newer version of Kubernetes is to first upgrade the control plane and then upgrade the node pools. Here are the steps to follow: Upgrade the control plane: Initiate the upgrade process for the control plane using the OCI Console, CLI, or API. This upgrade will update the Kubernetes control plane components running in the master nodes of the cluster. Upgrade the node pools: After the control plane upgrade is completed, you can proceed to upgrade the node pools. A node pool is a set of worker nodes within the cluster. You can upgrade the node pools one at a time or simultaneously, depending on your requirements and cluster configuration. By following this approach, you ensure that the control plane is upgraded first, which ensures compatibility and stability with the new version of Kubernetes. Afterward, you can upgrade the node pools to ensure all worker nodes are running the latest version of Kubernetes. It is important to note that before performing any upgrades, it is recommended to review the release notes and upgrade documentation provided by Oracle for any specific instructions or considerations related to the version you are upgrading to.

						Question 25					
					
						You host your application on a stack in Oracle Cloud Infrastructure (OCI) Resource Manager. Due to recent growth in your user base, you decide to add a CIDR block to your VCN, add a subnet, and provision a compute instance in it. Which statement is true?
					
					
						Options:
						A. You need to provision a new stack because Terraform uses immutable infrastructure.
						B. You can provision the new resources in the OCI console and add them to the stack with Drift Detection.
						C. You cannot provision the new resources in the OCI console first, then later add them to the Terraform configuration and state.
						D. You can make the changes to the Terraform code, run an Apply job, and Resource Manager will provision the new resources.
						
						
						
					
					
						
						
							Answer:
							A

														Explanation:
							Explanation: Explanation
The correct statement is: You need to provision a new stack because Terraform uses immutable in-frastructure. In Oracle Cloud Infrastructure (OCI) Resource Manager, Terraform uses the concept of immutable infrastructure, which means that any changes to the infrastructure are managed through the Terraform code. In this scenario, if you want to add a CIDR block, subnet, and compute instance to your VCN, you would need to make the necessary changes to your Terraform code, create a new stack in Resource Manager, and deploy the updated code. This ensures that the infra-structure is created consistently and according to the desired state defined in the Terraform code. Simply provisioning the new resources in the OCI console and later adding them to the Terraform configuration and state would not be the recommended approach in this case.

													
					
				

							
					
						Question 26					
					
						How does the Oracle Cloud Infrastructure Container Engine for Kubernetes (OKE) Cluster Autoscaler determine when to create new nodes for an OKE cluster?
					
					
						Options:
						A. When the resource requests from pods exceed a configured threshold.
						B. When the rate of requests to the application crosses a configured threshold.
						C. When the custom metrics from the services exceed a configured threshold.
						D. When the CPU or memory utilization crosses a configured threshold.
						
						
						
					
					
						
						
							Answer:
							A

														Explanation:
							Explanation: Explanation
The Kubernetes Cluster Autoscaler increases or decreases the size of a node pool automatically based on resource requests, rather than on resource utilization of nodes in the node pool. Reference: https://docs.oracle.com/en-us/iaas/Content/ContEng/Tasks/contengusingclusterautoscaler.htm 

													
					
				

							
					
						Question 27					
					
						A developer is using the Oracle Cloud Infrastructure (OCI) DevOps service to build an application. They are currently in the process of setting up the required infrastructure using the available tools. In which two ways can you explain the difference between Ansible and Terraform? (Choose two.)
					
					
						Options:
						A. Ansible uses declarative approach: Terraform is procedural in nature.
						B. Ansible is an OCI provided service for CM; Terraform is a third-party tool for infra-structure as code.
						C. Ansible focuses on infrastructure configuration: Terraform specializes in infrastructure provisioning
						D. Ansible supports lifecycle management: Terraform lacks lifecycle management support.
						E. Ansible automates software installation and application deployment: Terraform man-ages infrastructure as code.
						
						
					
					
						
						
							Answer:
							C, E

														Explanation:
							Explanation: Explanation
The two correct explanations for the difference between Ansible and Terraform are: Ansible auto-mates software installation and application deployment, while Terraform manages infrastructure as code. This highlights the primary focus of each tool. Ansible is mainly used for automating tasks related to software installation, application deployment, and configuration management. It is well-suited for managing the software stack and ensuring consistency across systems. On the other hand, Terraform specializes in infrastructure provisioning and management, allowing users to define and manage their infrastructure resources using code. Ansible focuses on infrastructure configuration, while Terraform specializes in infrastructure provisioning. This highlights the different aspects of infrastructure management that each tool addresses. Ansible is designed to handle configuration management tasks, such as setting up software, managing files, and applying configuration changes across systems. It excels at ensuring the desired state of the infrastructure. In contrast, Terraform is focused on provisioning infrastructure resources, such as virtual machines, networks, and storage. It provides a way to define and manage these resources in a declarative manner, allowing for infra-structure as code. It's worth noting that while Ansible is supported and provided by OCI as a con-figuration management tool, Terraform is a third-party tool that has gained popularity for managing infrastructure across multiple cloud providers, including OCI.
													
					
				

							
					
						Question 28					
					
						Your customer has deployed their microservices based application on Oracle Container Engine for Kubernetes (OKE) and they are using Oracle Cloud Infrastructure Registry (OCIR) service as their Docker image repository. They have deployed the OKE cluster using the 'custom create' option, and their Virtual Cloud Network (VCN) has three public subnets with associated route tables, security lists, and an internet gateway. They are facing an issue where their application containers are falling to deploy. Upon investigation, they learn that the images are not getting pulled from the designated OCIR repository. The YAML configuration has the correct path to the images. What is a valid concern that needs to be further investigated?
					
					
						Options:
						A. The OKE cluster needs to have a secret with credentials of their OCIR repository and use that secret in the Kubernetes deployment manifest.
						B. They need to add IAM credentials for each user that deploys applications to the OKE cluster.
						C. The VCN hosting the OKE cluster worker nodes needs to have a NAT gateway to access OCIR repositories.
						D. They need to add a security list rule for TCP port 22 to connect to the OCIR service.
						
						
						
					
					
						
						
							Answer:
							A

														Explanation:
							Explanation: Explanation
A valid concern that needs to be further investigated in this scenario is whether the OKE cluster has a secret with credentials of the Oracle Cloud Infrastructure Registry (OCIR) repository and if that secret is being used in the Kubernetes deployment manifest. When deploying an application on OKE and pulling images from OCIR, the cluster needs to authenticate and authorize access to the OCIR repository. This is typically done by creating a Kubernetes secret that contains the credentials (authentication token or username/password) required to access the repository. The secret is then referenced in the Kubernetes deployment manifest to allow the cluster to pull the images. If the images are not getting pulled from the designated OCIR repository, it suggests that the OKE cluster might be missing the necessary secret with the OCIR credentials or the secret is not properly referenced in the deployment manifest. Further investigation should focus on ensuring the existence and correct configuration of the secret and its usage in the deployment process.
													
					
				

							
					
						Question 29					
					
						What is the DevOps lifecycle, and how does it help businesses succeed?
