NEW QUESTION # 53
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 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.
- 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 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.
- D. 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.
Answer: B
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.
NEW QUESTION # 54
You are a security administrator for your company's Oracle Cloud Infrastructure (OCI) ten-ancy. Your storage administrator tells you that they cannot associate an encryption key from OCI Vault to an Object Storage bucket in a new compartment, what is the reason?
- A. The storage administrator forgot to select "Oracle Managed" while creating the bucket.
- B. There is no Identity and Access Management (IAM) policy allowing the Object Store service to use the Vault key.
- C. The secret for the key was not created beforehand.
- D. The resource bucket policy lacks the necessary Access Control List (ACL).
Answer: C
Explanation:
Explanation
The reason why the storage administrator cannot associate an encryption key from OCI Vault to an Object Storage bucket in a new compartment could be: There is no Identity and Access Management (IAM) policy allowing the Object Store service to use the Vault key. This is because an IAM policy is required to authorize the Object Storage service to use the encryption key from OCI Vault. The IAM policy should allow the service to use the key and also give permission to access the Vault resource. Without the appropriate IAM policy in place, the storage administrator will not be able to associate the encryption key with the Object Storage bucket.
Here is the link to the official documentation on associating an Oracle-managed encryption key from OCI Vault with an Object Storage bucket: Reference:

NEW QUESTION # 55
ABC Inc. is a software development firm that uses DevOps practices. They want to minimize the risk of security breaches by incorporating security into their development process from the start. To accomplish this, they are concentrating on incorporating DevSecOps best practices into their DevOps process. Which three are best practices that ABC Inc. should im-plement?
- A. Have a flat network with no segmentation or isolation, where all devices and resources are interconnected and accessible to anyone on the network.
- B. Implement role-based access control and define roles and responsibilities for everyone involved in the development process.
- C. Manually execute DevOps security processes and tools to reduce the risk of errors and security incidents.
- D. Perform regular scans for vulnerabilities and prioritize fixing them based on their se-verity
- E. Follow established security guidelines, such as the OWASP DevSecOps guideline, during the development and testing process.
Answer: B,D,E
Explanation:
Explanation
The best practices that ABC Inc. should implement to incorporate DevSecOps into their DevOps process are:
* Follow established security guidelines, such as the OWASP DevSecOps guideline, during the development and testing process. The OWASP DevSecOps guideline is a set of recommendations and tools that help developers and testers integrate security into every stage of the software development lifecycle (SDLC). The guideline covers topics such as threat modeling, secure coding, code analysis, security testing, vulnerability management, etc.
* Perform regular scans for vulnerabilities and prioritize fixing them based on their severity. Vulnerability scanning is a process of identifying and assessing the security risks in your code, dependencies, images, containers, or infrastructure. You can use tools such as SonarQube, Sonatype Nexus IQ Server, or
* Twistlock to perform vulnerability scanning and generate reports with detailed information and remediation suggestions. You should also prioritize fixing the vulnerabilities based on their severity level and potential impact.
* Implement role-based access control and define roles and responsibilities for everyone involved in the development process. Role-based access control (RBAC) is a method of restricting access to resources based on the roles of the users or groups. You can use RBAC to enforce the principle of least privilege, which means granting only the minimum level of access required for each user or group to perform their tasks. You should also define clear roles and responsibilities for everyone involved in the development process, such as developers, testers, operations staff, security staff, etc., and assign them appropriate permissions and policies.

NEW QUESTION # 56
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?
- A. You can provision the new resources in the OCI console and add them to the stack with Drift Detection.
- B. You cannot provision the new resources in the OCI console first, then later add them to the Terraform configuration and state.
- C. You need to provision a new stack because Terraform uses immutable infrastructure.
- D. You can make the changes to the Terraform code, run an Apply job, and Resource Manager will provision the new resources.
Answer: C
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.
NEW QUESTION # 57
You are a DevOps project administrator. You are creating Oracle Cloud Infrastruc-ture (OCI) Identity and Access Management (IAM) policies that will be used in a DevOps CI/CD pipeline for deployment to an Oracle Container Engine for Kubernetes (OKE) environment. Which OCI IAM policy can be used?
- A. Allow group <deployment pipeline> to manage devops-family in compartment <com-partment name>
- B. Allow dynamic-group <deployment pipeline to manage all-resources in compartment <compartment name>
- C. Allow group <build pipeline> to manage all-resources in compartment <compartment name>
- D. Allow dynamic-group <code repository> to manage devops-family in compartment <compartment name>
Answer: B
Explanation:
Explanation
To create an OCI IAM policy that will be used in a DevOps CI/CD pipeline for deployment to an OKE environment, you need to use a dynamic group and grant it the permission to manage all-resources in the target compartment. A dynamic group is a group of OCI resources that match a set of rules defined by the administrator. You can use a dynamic group to assign IAM policies to resources such as build pipelines and deployment pipelines. By granting the dynamic group the permission to manage all-resources, you allow it to perform any action on any resource type in the compartment, including OKE clusters, node pools, and Kubernetes resources.

NEW QUESTION # 58
Using the Oracle Cloud Infrastructure (OCI) Vault service, you created a secret and rotated. one time. The current version state shows: Version Number : 2 (latest) | Status: Cur-rent Version Number: 1 | Status:
Previous In order to rollback to version 1, what should you do?
- A. From the version 2 (latest) menu, select "Rollback..." and select version 1 when given the option.
- B. Deprecate version 2 (latest). Create new Secret Version 3. Create soft link from version 3 to version 1.
- C. Create a new secret version 3 and set it to Pending. Copy the contents of Version 1 into version 3.
- D. From the version 1 menu, select "Promote to Current".
Answer: D
Explanation:
Explanation
To rollback to version 1 of a secret that has been rotated once, you need to do the following:
* From the version 1 menu, select "Promote to Current". This will change the status of version 1 from Previous to Current, and change the status of version 2 from Current to Previous. This means that version 1 will be used as the current key version for encrypting and decrypting secrets.
* Optionally, you can also delete version 2 if you no longer need it. From the version 2 menu, select
"Delete". This will change the status of version 2 from Previous to Deleted. You can also restore or destroy deleted versions if needed. Verified References: [Rotating Secrets - Oracle Cloud Infrastructure Vault], [Managing Secret Versions - Oracle Cloud Infrastructure Vault]
NEW QUESTION # 59
How can customers rotate their master encryption keys in the Oracle Cloud Infra-structure (OCI) Vault service?
- A. If you import your own key, you cannot rotate the key. You will have to import a new key to rotate.
- B. 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.
- 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.

- C. You must have an auth token to encrypt the secret.
- D. The user must create a compute instance to run the secret service.
- E. You must have the required permissions to create and manage secrets in the Vault service.
Answer: A,E
Explanation:
Explanation
To create a secret in OCI Vault service, you need to have the following prerequisites:
* You must have a Vault managed key to encrypt the secret. A Vault managed key is a symmetric encryption key that is generated and managed by the Vault service. You can use a Vault managed key to encrypt and decrypt secrets, such as passwords, API keys, certificates, etc.
* You must have the required permissions to create and manage secrets in the Vault service. You need to have the IAM policies that allow you to access the Vault compartment, the Vault itself, and the Vault managed key. You also need to have the secret management policies that allow you to create, read, update, delete, or restore secrets.

NEW QUESTION # 61
Which is a proper rule to follow when creating container repositories inside the Oracle Cloud Infrastructure (OCI) Registry?
- A. When creating a container repository, check the Immutable Artifacts box, as it keeps other developers from altering the files.
- B. You must use a separate container repository for each image, but multiple versions of that image can be in a single repository.
- C. When naming a container repository, you may use capital letters but not hyphens. For example, you may use BGdevops-storefront, but not bgdevops/storefront.
- D. 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.
Answer: B
Explanation:
Explanation
The proper rule to follow when creating container repositories inside the Oracle Cloud Infrastructure (OCI) Registry is: You must use a separate container repository for each image, but multiple versions of that image can be in a single repository. This means that each distinct image should have its own repository, but different versions of the same image can be stored within that repository. This allows for better organization and management of container images. The other options mentioned are not correct: Checking the "Immutable Artifacts" box does not exist as a requirement when creating a container repository. Immutable artifacts refer to the immutability of the container images themselves, not a setting in the repository. There are no restrictions on using capital letters or hyphens in the naming of container repositories. Both capital letters and hyphens are allowed in the repository name. The OCI DevOps Managed Build stage is not directly related to defining artifacts in the artifact and container repositories. The Managed Build stage is responsible for building and packaging application artifacts, but it does not define the repositories themselves.

OCI DevOps provides capabilities to automate and streamline the entire software development process, including building, testing, deploying, and managing applications and infrastructure. It enables developers to implement CI/CD practices and deliver software more efficiently and reliably.
NEW QUESTION # 64
In the DevOps lifecycle, what is the difference between continuous delivery and continuous deployment?
- A. Continuous delivery requires more automatic linting, while continuous deployment testing must be run manually.
- B. Continuous delivery involves automation of developer tasks, while continuous deployment involves manual operational tasks.
- C. Continuous delivery utilizes automatic deployment to a development environment, while continuous deployment involves automatic deployment to a production environment.
- D. Continuous delivery is a process that initiates deployment manually, while continuous deployment is based on automating the deployment process.
Answer: D
Explanation:
Explanation
The correct answer is: Continuous delivery is a process that initiates deployment manually, while continuous deployment is based on automating the deployment process. In the DevOps lifecycle, continuous delivery and continuous deployment are both approaches to software release and deployment, but they differ in the level of automation and manual intervention involved. Continuous delivery refers to the practice of continuously preparing software releases in a way that they could be deployed to production at any time. It focuses on automating the build, test, and deployment processes, ensuring that software is always in a deployable state.
However, the decision to actually deploy the software to production is made manually, typically by a human operator or team. On the other hand, continuous deployment takes the automation one step further. With continuous deployment, the software is automatically deployed to production as soon as it passes all the necessary tests and checks. There is no manual intervention in the deployment process, and it is fully automat-ed. This approach allows for faster and more frequent deployments, reducing the time between developing new features and making them available to users. So, the main difference is that continuous delivery requires a manual trigger for deployment to production, while continuous deployment automates the deployment process without the need for manual intervention.
NEW QUESTION # 65
You host a microservices based application on the Oracle Cloud Infrastructure Con-tainer Engine for Kubernetes (OKE). Due to increased popularity of your application, you need to provision more resources to meet the growing demand. Which three statements are true for the given scenario?
- A. Scale a cluster up and down by changing the number of node pools in the cluster.
- B. Enable cluster autoscaling by autoscaling node pools by deploying Kubernetes Metrics Server and using the Kubernetes Vertical Pod Autoscaler to adjust the resource re-quests and limits.
- C. Scale a node pool up and down to change the number of worker nodes in the node pool, and the availability domains and subnets in which to place them.
- D. Enable cluster autoscaling by autoscaling node pools by deploying the Kubernetes Autoscaler to automatically resize a cluster's node pools based on application workload demands.
- E. Enable autoscaling by autoscaling Pods by deploying Kubernetes Autoscaler to collect resource metrics from each worker node in the cluster.
Answer: C,D,E
Explanation:
Explanation
The statements that are true for scaling an OKE cluster to meet growing demand are:
* Enable autoscaling by autoscaling Pods by deploying Kubernetes Autoscaler to collect resource metrics from each worker node in the cluster. Pod autoscaling is a feature that allows you to adjust the number of pods in a deployment or replica set based on the CPU or memory utilization of the pods. You can use Kubernetes Autoscaler, which is an add-on component that you can install on your OKE cluster, to collect resource metrics from each worker node and scale the pods up or down accordingly.
* Enable cluster autoscaling by autoscaling node pools by deploying the Kubernetes Autoscaler to automatically resize a cluster's node pools based on application workload demands. Cluster autoscaling is a feature that allows you to adjust the number of nodes in a node pool based on the pod requests and limits of the pods running on the nodes. You can use Kubernetes Autoscaler, which is an add-on component that you can install on your OKE cluster, to monitor the pod requests and limits and scale the node pools up or down accordingly.
* Scale a node pool up and down to change the number of worker nodes in the node pool, and the availability domains and subnets in which to place them. A node pool is a group of worker nodes within an OKE cluster that share the same configuration, such as shape, image, subnet, etc. You can use OCI Console, CLI, or API to scale a node pool up and down by adding or removing worker nodes from it.
You can also change the availability domains and subnets for your node pool to distribute your nodes across different fault domains. Scaling a node pool allows you to adjust your cluster capacity according to your application workload demands.

NEW QUESTION # 66
Your application development team has an existing GitHub repository for their code. Your application development team has an existing GitHub repository for their code. You would like to mirror it on Oracle Cloud Infrastructure (OCI) in order to deploy an application to an Oracle Container Engine for Kubernetes (OKE) environment using the OCI DevOps service. Which action can be done AFTER you trigger a Build Pipeline?
- A. Set up a Kubernetes cluster as an environment for deployment
- B. Configure an OCI compartment for storing DevOps resources
- C. Create a reference to a secret in the OCI Vault
- D. Configure the SSH file so that their SSH key is used when connecting to OCI Code Repositories
Answer: C
Explanation:
Explanation
After triggering a Build Pipeline in the OCI DevOps service, you can perform the following action: Create a reference to a secret in the OCI Vault: This allows you to securely store and manage secrets, such as API keys or passwords, that are required for the deployment process. By referencing the secret in the OCI Vault, you can ensure that sensitive information is protected and easily accessible during the deployment. The other options mentioned are not directly related to actions that can be performed after triggering a Build Pipeline:
Setting up a Kubernetes cluster as an environment for deployment is typically done before triggering the Build Pipeline. It involves provisioning the necessary infrastructure to support the deployment of containerized applications. Configuring an OCI compartment for storing DevOps resources is a configuration step that is done independently of the Build Pipeline. Compartments are used to organize and manage resources in OCI, but they are not directly related to the Build Pipeline process. Configuring the SSH file for OCI Code Repositories is not an action that is performed after triggering the Build Pipeline. SSH keys are typically configured before interacting with code repositories, and they are not specific to the Build Pipe-line process.

- B. You can add a Wait stage that adds a specified duration of delay in the pipeline.
- C. Using deployment pipeline, you can deploy artifacts to Kubernetes cluster, Instance Group, and OCI Compute Instances.
- D. You can add an Approval stage that pauses the deployment for a specified duration for manual decision from the approver
Answer: B
Explanation:
Explanation
The statement that is false about deployment pipeline in OCI DevOps is that you can add a Wait stage that adds a specified duration of delay in the pipeline. This is not a valid type of stage that you can add to your deployment pipeline. The types of stages that you can add to your deployment pipeline are:
* Deploy stage: A stage that deploys an artifact to a target environment, such as Kubernetes, Instance Group, or Compute Instance.
* Control stage approval: A stage that pauses the pipeline execution and requires manual approval before proceeding to the next stage.
* Traffic shift stage: A stage that routes the traffic between two sets of backend IPs using a preconfigured load balancer and listener.
* Invoke function stage: A stage that invokes an Oracle Function with specified parameters and payload.

NEW QUESTION # 69
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. 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.
- B. 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.
- C. Storing build artifacts in registries helps the deployment pipeline differentiate output artifacts created by the build pipeline from artifacts copied from a Git repository.
- D. 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.
Answer: B
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.
