NEW QUESTION # 21
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. Build the web app as one unit and use container technology for deployment
- B. Prefer Monolithic web app over microservices
- C. Use independent service which can be replaced or updated without any impact on the web app
- D. Avoid long duration commitment to a technology stack using microservice architecture
Answer: C,D
Explanation:
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 It also reduces the risk of being locked into a technology stack that may become outdated or less effective over time.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.

How do OCI DevOps deployment pipelines reduce risk and complexity of production applications?
- A. By eliminating downtime of production applications
- B. By reducing change-driven errors introduced by manual deployments
- C. By working with existing Git repositories and Cl systems
- D. By scaling builds with service-managed build runners
Answer: B
Explanation:
Explanation
One of the ways that OCI DevOps deployment pipelines reduce risk and complexity of production applications is by reducing change-driven errors introduced by manual deployments. A deployment pipeline is a sequence of stages that automates the delivery of software from source code to production. By using a deployment pipeline, you can eliminate human errors, enforce quality checks, and ensure consistency across different environments. A deployment pipeline also enables faster feedback loops, easier rollback, and improved traceability of changes. Verified References: [Deployment Pipelines - Oracle Cloud Infrastructure DevOps],

NEW QUESTION # 23
A company wants to implement CI/CD automation process on Oracle Cloud Infrastructure (OCI) DevOps. An automatic trigger is created in such a way that when someone pushes the code from a Git repository to the OCI Code Repository, it trigger builds all the way to the deployment pipeline. Which DevOps IAM policy statements are required for this automation?
- A. Build Pipeline: allow dynamic-group <BuildPipeline> to manage all-resources in compartment
<compartment names> - B. Code Repo: Allow dynamic-group <Code Repository> to manage all-resources in compartment
<compartment name>; Build Pipeline: Allow dynamic-group <BuildPipelines to manage all-resources in Compartment compartment name>; Deployment Pipeline: allow dynamic-group <Deployment Pipeline> to manage all resources in compartment scompartment name> - C. No DevOps IAM policy statements are required.
- D. Code Repo: Allow dynamic group <Code Repository> to manage all resources in compartment compartment name>; Build Pipeline: Allow dynamic-group <BuildPipeline> to manage all-resources in compartment compartment name>
Answer: B
Explanation:
Explanation
The correct DevOps IAM policy statements required for the CI/CD automation process are: Code Repo: Allow dynamic-group <Code Repository> to manage all resources in compartment <com-partment name> Build Pipeline: Allow dynamic-group <BuildPipeline> to manage all resources in compartment <compartment name> Deployment Pipeline: Allow dynamic-group <Deployment Pipeline> to manage all resources in compartment <compartment name> These policy statements ensure that the specified dynamic groups have the necessary permissions to manage all resources within the specified compartments. The Code Repository dynamic group should have permissions to manage resources in the Code Repository compartment, the BuildPipeline dynamic group should have permissions to manage resources in the Build Pipeline compartment, and the Deployment Pipe-line dynamic group should have permissions to manage resources in the Deployment Pipeline compartment. This allows for the automation process to trigger builds and deployments as code is pushed to the Code Repository.
NEW QUESTION # 24
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?
- 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 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.

NEW QUESTION # 25
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. There is no Identity and Access Management (IAM) policy allowing the Object Store service to use the Vault key.
- B. The resource bucket policy lacks the necessary Access Control List (ACL).
- C. The secret for the key was not created beforehand.
- D. The storage administrator forgot to select "Oracle Managed" while creating the bucket.
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:

Answer: A,E,F
Explanation:
Explanation
The three actions that the DevOps Engineer must perform to easily manage and troubleshoot applications on Oracle Cloud Infrastructure Container Engine for Kubernetes (OKE) are: Create a service account and the clusterrolebinding, obtain an authentication token for the service account using the kubectl command, and run a kubectl proxy command to enable the Kubernetes dashboard. This allows for easy access to the dashboard and management of deployed applications. Automatically deploy the Kubernetes dashboard during cluster creation, create the cluster using the API, and set the iskubernetesDashboardEnabled attribute to true. This ensures that the Kubernetes dashboard is automatically deployed and accessible. Manually deploy the Kubernetes dashboard on an existing cluster and access it using the appropriate URL. This involves deploying the dashboard manually and accessing it through the specified URL, which allows for management and troubleshooting of applications. Using these actions, the DevOps Engineer can effectively manage and troubleshoot applications deployed on OKE, leveraging the Kubernetes dashboard for enhanced visibility and control.
NEW QUESTION # 27
A small company is moving to a DevOps framework to better accommodate their intermittent workloads, which are dynamic and irregular. They want to adopt a consumption-based pricing model. Which Oracle Cloud Infrastructure service can be used as a target deployment environment?
- A. Oracle Kubernetes (OKE)
- B. Virtual machine compute instance
- C. Functions
- D. Bare metal compute instance
Answer: C
Explanation:
Explanation
The OCI service that can be used as a target deployment environment for intermittent workloads with a consumption-based pricing model is Functions. Functions is a fully managed, serverless platform that allows you to run your code without provisioning or managing any servers. You can use Functions to develop and deploy isolated web applications or RESTful APIs using Node.js, Python, Java, or Go. You only pay for the resources you consume when your code is executed, which is ideal for dynamic and irregular workloads.

NEW QUESTION # 29
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. They need to add a security list rule for TCP port 22 to connect to the OCIR service.
- 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. The OKE cluster needs to have a secret with credentials of their OCIR repository and use that secret in the Kubernetes deployment manifest.
Answer: D
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.
NEW QUESTION # 30

NEW QUESTION # 34
You are processing business transactions within applications deployed to Oracle Container Engine for Kubernetes (OKE). As each batch of 1000 transactions are processed, a status file is created and uploaded to an Oracle Cloud Infrastructure (OCI) Object Storage buck-et. Each time a new file is created, you need to send an email to the customer to indicate final processing status. The solution should require the least amount of development effort, while still providing for a best effort guaranteed delivery. Which approach should be used to trigger these emails?
- A. Deploy an Oracle Function that checks the bucket every 60 seconds, then sends an email when a new file is found.
- B. Create an alert in the OCI Monitoring service that triggers an email when the monitored bucket is updated.
- C. Create a rule in the OCI Events service that sends the bucket event to an OCI Notifications service topic configured with an email subscriber.
- D. Define and schedule a Cron job that monies the bucket, then sends an email when a new file is found.
Answer: C
Explanation:
Explanation
The approach that should be used to trigger emails when a new file is created in an OCI Object Storage bucket is to create a rule in the OCI Events service that sends the bucket event to an OCI Notifications service topic configured with an email subscriber. The OCI Events service is a service that allows you to react to changes in your OCI resources by creating rules that match events of interest and trigger actions based on those events.
The OCI Notifications service is a service that allows you to broadcast messages to distributed components through topics and subscriptions. By using these services together, you can achieve the following workflow:
* Create an OCI Notifications service topic and add an email subscriber with the customer's email address.
* Create an OCI Events service rule that matches the Object Storage bucket event type
"com.oraclecloud.objectstorage.createobject" and specifies the Notifications topic as the action.
* Whenever a new file is created in the Object Storage bucket, an event will be generated and matched by the rule, which will send a message to the Notifications topic.
* The Notifications topic will deliver the message to the email subscriber, which will trigger an email to the customer. Verified References: [Events - Oracle Cloud Infrastructure Developer Tools],

NEW QUESTION # 35
How can customers rotate their master encryption keys in the Oracle Cloud Infra-structure (OCI) Vault service?
- A. Customers can only have OCI rotate their keys once a year.
- B. Customers can rotate their keys by creating a new Key Version.
- C. 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.
- D. If you import your own key, you cannot rotate the key. You will have to import a new key to rotate.
Answer: B
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.

- B. Add a containers section that specifies the name and location of the images you want to pull from OCIR.
along with other deployment details. - C. Add an image section that specifies the name and location of the images you want to pull from OCIR along with other deployment details.
- D. Add an Auth section to the manifest file that specifies the name of the Docker secret you create using Auth Token to access OCIR.
- E. Use kubectl to create a Docker registry secret.
Answer: A,B,E
Explanation:
Explanation
The three statements that are true regarding managing an application deployed in Oracle Cloud Infrastructure Container Engine for Kubernetes (OKE) and pulling images from Oracle Cloud Infra-structure Registry (OCIR) are: Use kubectl to create a Docker registry secret: To access images from OCIR, you need to create a Docker registry secret in Kubernetes. This can be done using the ku-bectl create secret docker-registry command. Add a containers section that specifies the name and location of the images you want to pull from OCIR, along with other deployment details: In your deployment manifest (e.g., YAML file), you need to define a containers section that specifies the image names and locations from OCIR. This section includes other deployment details such as re-source limits and environment variables. Add an imagePullSecrets section to the manifest file that specifies the name of the Docker secret you created to access OCIR: To authenticate and pull images from OCIR, you need to specify the name of the Docker registry secret in the imagePullSecrets section of your manifest file. This ensures that the appropriate credentials are used to authenticate with OCIR and pull the required images. These steps enable your application deployed in OKE to pull the necessary container images from OCIR during deployment, ensuring smooth and secure deployment of your application. Reference:
