質問 # 17
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?
- A. The VCN hosting the OKE cluster worker nodes needs to have a NAT gateway to access OCIR repositories.
- B. They need to add a security list rule for TCP port 22 to connect to the OCIR service.
- C. They need to add IAM credentials for each user that deploys applications to the OKE cluster.
- D. The OKE cluster needs to have a secret with credentials of their OCIR repository and use that secret in the Kubernetes deployment manifest.
正解：D
解説：
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.
質問 # 18
Your organization needs to design and develop a containerized application that requires a connection to an Oracle Autonomous Transaction Processing (ATP) Database. As a DevOps engineer, you have decided to use Oracle Container Engine for Kubernetes (OKE) for the container app deployment and you need to consider options for connecting to ATP. Which connection option is NOT valid?
- A. Install the OCI Service Broker on the Kubernetes cluster and deploy serviceinstance and ServiceBinding resources for ATP. Then use the specified binding name as a volume in the application deployment manifest.
- B. Create a Kubernetes secret with contents from the ATP instance Wallet files. Use this secret to create a volume mounted to the appropriate path in the application deployment manifest.
- C. Use Kubernetes secrets to configure environment variables on the container with ATP instance OCID and OCI API credentials. Then use the CreateConnection API endpoint from the service runtime.
- D. Enable Oracle REST Data Services for the required schemas and connect via HTTPS.
正解：D
解説：
Explanation
The connection option that is NOT valid for connecting to an Oracle Autonomous Transaction Pro-cessing (ATP) Database from Oracle Container Engine for Kubernetes (OKE) is: Enable Oracle REST Data Services for the required schemas and connect via HTTPS. Enabling Oracle REST Data Services (ORDS) is not a valid method for connecting to an ATP Database from OKE. ORDS is a tool that allows you to create RESTful web services against Oracle databases. However, it is not the recommended method for establishing a connection between a containerized application in OKE and an ATP Database. The other three options mentioned are valid approaches: Creating a Kuber-netes secret with contents from the ATP instance Wallet files: This allows you to securely store and use the necessary credentials to connect to the ATP Database in your application's deployment man-ifest. Using Kubernetes secrets to configure environment variables on the container with ATP in-stance OCID and OCI API credentials: This approach allows you to set environment variables with-in your application container to provide the necessary connection details to the ATP Database. In-stalling the OCI Service Broker and deploying serviceinstance and ServiceBinding resources for ATP: The OCI Service Broker simplifies the process of provisioning and managing Oracle Cloud Infrastructure (OCI) services, including ATP, from within Kubernetes. This option allows you to create a service binding that provides the necessary connection information to your application as a volume in the deployment manifest. These options provide more direct and secure connections be-tween the containerized application in OKE and the ATP Database, ensuring proper integration and data access.
質問 # 19
As a DevOps Engineer, you need to develop a web app for a company. The web app should support users using mobile browsers and native mobile applications. You need to recommend an architecture which can be easily upgraded, deployed independently and resilient to failures. Which TWO recommendations should you consider? (Choose two.)
- A. Avoid long duration commitment to a technology stack using microservice architecture
- B. Build the web app as one unit and use container technology for deployment
- C. Prefer Monolithic web app over microservices
- D. Use independent service which can be replaced or updated without any impact on the web app
正解：A、D
解説：
Explanation
The two recommendations to consider for developing a web app that supports users on mobile browsers and native mobile applications, and is easily upgradable, independently deployable, and resilient to failures are:
Use independent services: By adopting a microservices architecture, you can break down the web app into smaller, loosely coupled services that can be developed, deployed, and upgraded independently. Each service can focus on a specific functionality or feature of the web app, allowing for easier maintenance, scalability, and resilience to failures. This approach enables you to replace or update individual services without impacting the entire web app. Avoid long duration commitment to a technology stack: By using a microservices architecture, you can avoid long-term commitments to a specific technology stack. Each microservice can be developed using the most suitable technology or programming language for its specific requirements. This flexibility allows you to leverage the latest technologies and frameworks, adapt to changing needs, and take advantage of advancements in the development ecosystem. It also reduces the risk of being locked into a technology stack that may become outdated or less effective over time. Building the web app as one monolithic unit would not provide the desired modularity, independent deployment, and upgradability.
Container technology, such as Docker, can be used in conjunction with the recommended microservices architecture to provide a consistent and portable deployment mechanism, but it is not a standalone recommendation in this case.

質問 # 21
In the DevOps lifecycle, what is the difference between continuous delivery and continuous deployment?
- A. Continuous delivery is a process that initiates deployment manually, while continuous deployment is based on automating the deployment process.
- 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 requires more automatic linting, while continuous deployment testing must be run manually.
正解：A
解説：
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.
質問 # 22
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. From the version 1 menu, select "Promote to Current".
- C. Create a new secret version 3 and set it to Pending. Copy the contents of Version 1 into version 3.
- D. Deprecate version 2 (latest). Create new Secret Version 3. Create soft link from version 3 to version 1.
正解：B
解説：
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]

You are creating stages for an Oracle Kubernetes Engine (OKE) deployment pipeline and would like to include as many actions as possible within the pipeline stages themselves. What are you able to include?
- A. Add a stage to deliver artifacts to an Oracle Cloud Infrastructure (OCI) Artifact Regis-try.
- B. Add a stage to apply the Kubernetes manifest to the Kubernetes cluster.
- C. Add a stage to deploy incrementally to multiple OKE target environments.
- D. Add a stage to apply the container image to the Kubernetes cluster.
正解：A
解説：
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.
質問 # 25
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. Configure the SSH file so that their SSH key is used when connecting to OCI Code Repositories
- B. Create a reference to a secret in the OCI Vault
- C. Set up a Kubernetes cluster as an environment for deployment
- D. Configure an OCI compartment for storing DevOps resources
正解：B
解説：
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.
質問 # 26
In OCI Secret management within a Vault, you have created a secret and rotated the secret one time. The current version state shows: Version Number Status 2 (latest) Current 1 Previous In order to rollback to version 1, what should the Administrator do?
- A. From the version 2 latest menu, sect Road and select version when given the option.
- B. Create a new secret version 3 Pending Copy the contents of Version 1 Into version 3.
- C. deprecate version 2 (latest), Create a new secret version 3, create soft link for version-3 to version 1.
- D. From the version menu, select "Promote to current.
(Correct)
正解：D
解説：
Explanation
The correct answer is: From the version menu, select "Promote to current." To rollback to a previous version in OCI Secret Management within a Vault, the administrator should select the desired version from the version menu and choose the option "Promote to current." In this scenario, the administrator wants to rollback to version 1, so they would select version 1 from the menu and promote it to the current version. This action will make version 1 the active and current version of the secret, replacing version 2. The "Promote to current" option allows administrators to switch between different versions of a secret and make a specific version the active one.

質問 # 29
You're using Oracle Cloud Infrastructure (OCI) DevOps to deploy your application on an Oracle Container Engine for Kubernetes (OKE) environment. You push your code to the OCI Code Repository, add a stage and configure the build pipeline. When you run the build, you see "unable to clone the repository" error. What could the configuration error be?
- A. More stages were added than required to the build pipeline.
- B. Artifacts and build spec are removed before running the build.
- C. Source files are connected directly to the build pipeline.
- D. Dynamic Groups access and OCI IAM policies to the code repository are not set.
正解：D
解説：
Explanation
The configuration error that could lead to the "unable to clone the repository" error is: Dynamic Groups access and OCI IAM policies to the code repository are not set: This error suggests that the necessary permissions and access controls have not been properly configured for the OCI Code Repository. Dynamic Groups and IAM policies control user access and permissions to various OCI re-sources, including code repositories.
Without the correct configuration, the build pipeline is unable to clone the repository and retrieve the source code. The other options mentioned are not directly related to the error mentioned: More stages were added than required to the build pipeline: Adding more stages to the build pipeline than necessary would not cause an error related to cloning the repository. It might impact the overall flow and logic of the pipeline, but it is not directly related to the repository cloning process. Source files connected directly to the build pipeline:
Connecting source files directly to the build pipeline is a typical setup and would not cause a "unable to clone the repository" error. Artifacts and build spec being removed before running the build: Removing artifacts and build specifications before running the build could impact the build process and result in other errors, but it would not specifically cause an error related to cloning the repository.

質問 # 30
You're using Oracle Cloud Infrastructure (OCI) DevOps service to automate your software releases to release features more frequently and with fewer errors. While deploying an update to production, one of your deployment stages failed. What action should you perform in your Deployment Pipeline?
- A. Use OCI DevOps Trigger and Rerun tool to avoid downtime.
- B. Rollback the failed stage in the pipeline to the previous successful released version.
- C. Add Rescue and Trigger stages to automatically trigger the failed deployment.
- D. Automate backup and use the rerelease stage in the Deployment Pipeline.
正解：B
解説：
Explanation
In the Deployment Pipeline, when a deployment stage fails during the deployment of an update to production, the recommended action is to: Rollback the failed stage in the pipeline to the previous successful released version. By rolling back the failed stage to the previous successful version, you can revert the deployment to a known stable state and prevent the failed changes from being re-leased to production. This helps to maintain the stability and integrity of the application. It allows you to address the issues encountered in the failed stage, make necessary fixes or adjustments, and then proceed with the deployment again once the issues are resolved.
The other options mentioned are not the most appropriate actions to perform in this scenario: Automating backup and using the rerelease stage: While backups are important for data protection, automating backup and using a rerelease stage would not directly address the failure in the deployment stage. It is more focused on data backup and recovery. Adding Rescue and Trigger stages: Adding Rescue and Trigger stages might help in certain situations, but they are not the primary solution for handling a failed deployment stage. They are more related to error recovery mechanisms or additional deployment steps, rather than specifically addressing the failed stage. Using OCI DevOps Trigger and Rerun tool: While OCI DevOps Trigger and Rerun tool can be useful for automating and managing deployments, it is not specifically designed to handle a failed deployment stage. It is more focused on triggering and rerunning pipelines or stages based on specific conditions or events.

The difference between continuous deployment and continuous delivery in the DevOps lifecycle is that continuous delivery involves initiating deployments manually, while continuous deployment focuses on automating the deployment process. Explanation: Continuous delivery and continuous deployment are both practices in the DevOps lifecycle that aim to streamline the software release process. However, there is a distinction between the two based on the level of automation involved in the deployment phase. Continuous delivery refers to the ability to deliver software changes to production in a reliable and efficient manner. It involves having a well-defined deployment process and a reliable pipeline that can be triggered manually to deploy the software changes. With continuous delivery, the deployment process can be initiated by a human decision, allowing for a final re-view or approval before releasing the software. On the other hand, continuous deployment takes the automation aspect further by automatically deploying software changes to production as soon as they pass through the entire delivery pipeline. In continuous deployment, the deployment process is fully automated, and there is no human intervention required to initiate the deployment. Once the changes are tested and validated, they are automatically deployed to the production environment. In summary, continuous delivery involves manual initiation of the deployment process, while continuous deployment focuses on automating the deployment process without the need for human intervention.

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 length of time it takes to build each resource using these Terraform stacks.
- B. Resource Manager stacks are free but you are charged for the resources they create.
- C. The cost for each stack will be higher for a Pay As You Go subscription than for monthly flex billing.
- D. The cost depends on the number of lines of text in your Terraform configuration files.
正解：B
解説：
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.

A company has an Oracle Cloud Infrastructure (OCI) DevOps deployment pipeline set up in US East (us-ashburn 1) region, but they want to deploy an application in Japan Central (ap-osaka-1). How can they deploy their application in the ap-osaka-1 region with the deployment pipeline set up in the us ashburn-1 region in the most efficient manner?
- A. Deploy directly in ap-osaka-1 from the us-ashburn-1 deployment pipeline.
- B. It is not possible to use the same deployment pipeline across regions.
- C. Create another deployment pipeline in ap-osaka-1 to connect to the deployment pipeline in us ashburn-1
- D. Deploy application in us-ashburn-1 and duplicate the same in ap-osaka-1.
正解：A
解説：
Explanation
OCI DevOps deployment pipelines can work across OCI regions. From a single deployment pipe-line, deployments can be executed into multiple regions, in parallel or sequentially. To efficiently deploy an application in the Japan Central (ap-osaka-1) region using an existing deployment pipeline set up in the US East (us-ashburn-1) region, the recommended approach is: Deploy directly in ap-osaka-1 from the us-ashburn-1 deployment pipeline. OCI DevOps allows you to deploy applications across regions, and you can leverage this capability to deploy your application in a different region than where the deployment pipeline is set up. You can configure the deployment stage in your deployment pipeline to target the ap-osaka-1 region, specifying the appropriate resources and settings for deployment in that region. This way, you can achieve efficient deployment to the desired region without the need to create a separate deployment pipeline. The other options mentioned are not the most efficient approaches: Creating another deployment pipeline in ap-osaka-1:
While it is possible to create another deployment pipeline in the ap-osaka-1 region, it would introduce additional complexity and management overhead. It is more efficient to leverage the existing deployment pipeline and configure it to deploy in the desired region. Deploying the application in us-ashburn-1 and duplicating it in ap-osaka-1: This approach would involve deploying the application separately in both regions, which can lead to duplication of efforts and increased maintenance complexity. It is more efficient to use a single deployment pipeline and configure it to deploy in the target region directly.
