How can you scale a deployment named nodejs-deployment to have two replicas?

kubectl set replicas deployment nodejs-deployment –replicas=2

kubectl resize deployment nodejs-deployment –replicas=2

kubectl adjust deployment nodejs-deployment –replicas=2

kubectl scale deployment nodejs-deployment –replicas=2

The kubectl scale command is used to scale the number of replicas in a deployment. By specifying the –replicas flag, you define the desired number of replicas for the deployment.
(kubectl set replicas) is not the correct syntax for scaling a deployment.
(kubectl resize) is not a valid command for scaling a deployment.
(kubectl adjust) is also not a valid Kubernetes command.

FRAGE 29
You’re using Oracle Cloud Infrastructure (OCI) DevOps to automate your application deployment for frequent releases. In one of your automation steps, you’ll create a deployment pipeline.
What does this deployment pipeline do in OCI DevOps?

It takes a commit ID from your source code repositories and uses that source code to run your build instructions.

It is a sequence of steps for delivering and deploying your artifacts to a target environment.

It is used to store, manage, develop source code with OCI DevOps Code Repositories.

It is a set of stages for your build process for building, testing and compiling software artifacts.

A deployment pipeline in OCI DevOps is used to automate the deployment of application artifacts to a target environment. It is a sequence of stages that includes steps such as approvals, traffic shifts, manual interventions, and the actual deployment of the artifacts to environments like Kubernetes clusters or compute instances.

FRAGE 30
An operations team wants to leverage the advanced features of Container Engine for Kubernetes (OKE) and requires granular control over cluster add-ons, workload identity, and improved worker node management. They also prioritize strong security measures and require a financially-backed service level agreement (SLA) for Kubernetes API server uptime.
Which type of cluster should they choose to meet their requirements?

Enhanced clusters

Federated clusters

Virtual clusters

Specialized clusters

Enhanced clusters in Oracle Container Engine for Kubernetes (OKE) provide advanced features such as granular control over cluster add-ons, workload identity, and improved worker node management. They also offer strong security measures and come with a financially-backed service level agreement (SLA) for Kubernetes API server uptime, ensuring higher reliability and support for production workloads.

FRAGE 31
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?

Virtual machine compute instance

Oracle Kubernetes (OKE)

Bare metal compute instance

Functions

Oracle Cloud Infrastructure Functions is a serverless compute service that supports a consumption-based pricing model. This means that you are only charged for the compute resources when your function is invoked. This is ideal for intermittent, dynamic, and irregular workloads since the company does not need to provision infrastructure in advance, and costs are directly tied to usage.

FRAGE 32
You are a developer and have been asked to develop an e-commerce website for your organization. It must support a variety of clients including desktop browsers, mobile browsers and native mobile applications.
Which two approaches can you use to build the application to achieve deployment independence, easier technology upgrades, and resiliency to architecture changes? (Choose two.)

Use monolithic approach, as it allows you to easily redeploy your applications to perform frequent updates.

Implement each module as an independent service/process which can be replaced, updated, or deleted without disrupting the rest of the application.

Use monolithic approach to as it makes it easier to incrementally adapt to newer technology.

Choose monolithic approach over microservices as it has better fault isolation capability.

Use microservices architecture as it eliminates any long-term commitment to a technology stack.

By implementing each module as an independent service/process (which is a core feature of microservices architecture), you can replace, update, or delete services without affecting the rest of the application. This ensures deployment independence and makes it easier to adapt to architecture changes or technology upgrades without major disruptions.
Microservices architecture allows each service to be built with the best-suited technology stack for its specific function. This flexibility ensures that you are not tied to a single technology for the entire application, making future technology upgrades easier and eliminating long-term technology commitments.

FRAGE 33
Which command creates the docker registry secret required in the application manifests for OKE to pull images from Oracle Cloud Infrastructure Registry?

To create a Docker registry secret to pull images from the Oracle Cloud Infrastructure Registry (OCIR), you need to specify the correct parameters such as the region key, namespace, OCI username, and OCI authentication token.
Chosen command is correct because:
The kubectl create secret docker-registry command creates a Docker registry secret.
The –docker-server=<region-key>.ocir.io specifies the correct endpoint for OCIR.
The –docker-username=<tenancy-namespace>/<oci-username> provides both the tenancy namespace and the OCI username, which is the required format for authentication with OCIR.
The –docker-password='<oci-auth-token>’ specifies the OCI auth token, which acts as a password for authentication.
The –docker-email=<email-address> is also included.
The other commands have errors, such as missing tenancy namespace or using incorrect flags (passwd instead of secret).

FRAGE 34
While adding variables to your build_spec.yaml file, you made a mistake that resulted in a failed build pipeline.
What is the error you could have made?

Defined parameters such as the ${VARIABLE_NAME} file and later assigned their values in the Parameters tab of the build pipeline

Defined variables as exportedVariables to make them available in subsequent stages of the same pipeline

Defined a field such as type: DOCKER_IMAGE in the outputArtifacts: section to specify the docker image produced by the Build stage

Used vaultVariable to hold the content of the vault secrets in Base64 format

In build_spec.yaml for OCI DevOps, variables must be correctly defined and used according to the specification. If you defined parameters using ${VARIABLE_NAME} and then attempted to assign their values through the Parameters tab in the build pipeline, you may have introduced an error. The syntax and usage of parameters must be properly defined in both the build_spec.yaml and the build pipeline interface.

FRAGE 35
As a DevOps engineer working with OCI DevOps, you are managing artifacts for a microservices application.
Based on your understanding of working with DevOps projects and artifacts, which statement is true?

Artifacts can be used directly by OCI DevOps without the need for them to be located or mirrored in an OCI Artifact or Container registry.

In the build pipeline, to store the Managed Build stage outputArtifacts. you need an OCI Object storage.

It is recommended to make artifacts immutable to prevent any modifications after they are uploaded.

Once created, the artifact’s name. type, and source cannot be modified.

Making artifacts immutable ensures that the build artifacts are not altered after being published. This is a best practice to maintain the integrity and consistency of the artifacts used in deployments, preventing unintentional changes that could introduce issues during subsequent deployment stages.

FRAGE 36
As a developer working on a software project to be deployed on OKE, you have created a Helm chart for your application. You want to deploy the chart using OCI DevOps service.
Which statement is true about deploying a Helm Chart using OCI DevOps service?

A single chart can be installed only once into the same cluster, and create single release.

The Helm charts must be located in the OCI Container Registry repository for deployment.

The values.yaml file is a generic file located in the OCI Container Registry. You must create a reference to this file.

Oracle Cloud Infrastructure (OCI) DevOps service supports deployment of Helm charts to Container Instances.

OCI DevOps service can be used to deploy Helm charts for Kubernetes-based applications running on Oracle Kubernetes Engine (OKE). For deploying the Helm chart through the OCI DevOps service, the Helm chart must be stored in the OCI Container Registry. This allows the OCI DevOps service to easily access the Helm chart during the deployment process.

FRAGE 37
A DevOps team is deploying a new version of their application to their production environment using the Canary deployment strategy in the OCI DevOps service. They want to ensure that the production environment is not affected by any potential issues caused by the new version.
Which statement is true in regards to the Canary deployment strategy?

The Production stage in the Canary deployment strategy deploys the new version to the production environment without any manual approval.

The Canary deployment strategy only supports pipeline redeployment for OKE and not for instance group deployments.

The Invoke Function stage is an optional stage that can be used to validate the new version before moving to the production environment.

The Shift Traffic stage in the Canary deployment strategy shifts the entire 100% of the production traffic to the Canary environment.

In a Canary deployment strategy, a new version of an application is rolled out to a small subset of the production environment (the canary) first, while the majority of the production environment still runs the current stable version. This approach helps to detect potential issues before the new version is fully deployed.
The Invoke Function stage can be used as an optional step in the deployment pipeline to run additional validation (e.g., automated tests or other checks) on the new version before gradually shifting more traffic to it or moving to full production deployment.

FRAGE 38
Which OCI DevOps project resource is responsible for defining the stages for compiling, testing, and running software applications before deployment?

Deployment pipelines

Build pipelines

Development pipelines

Integration pipelines

Build pipelines in OCI DevOps are responsible for defining the stages involved in compiling, testing, and running software applications. These pipelines automate the process of building the code, running unit tests, scanning for vulnerabilities, and packaging the software, all of which occur before deploying the application.

FRAGE 39
A fully qualified path to a particular image in an OCIR repository is given as iad.ocir.io/ansh81vru1zp/project01/acme-web-app:version2.0.test.
Identify the two options with correct terms and their associated values. (Choose two.)

version2.0.test represents <tenancy-namespace>

ansh81vru1zp/project01/acme-web-app:version2.0.test represents <repo-name>

ansh81vru1zp represents <tenancy-namespace>

iad.ocir.io/ansh81vru1zp represents <region-key>

iad represents <region-key>

ansh81vru1zp is the <tenancy-namespace>. In Oracle Cloud Infrastructure Registry (OCIR), the tenancy namespace uniquely identifies the tenancy and is used as part of the image path.
iad is the <region-key>. The region key is the shorthand identifier for the OCI region (iad represents Ashburn region), and it is used in the fully qualified path for images stored in the Oracle Cloud Infrastructure Registry (OCIR).

FRAGE 40
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 all the required stage and configure the build and deployment pipeline. When you run the build, you see “unable to clone the repository” error.
What could the configuration error be?

The Docker image used in the pipeline is incompatible with the OKE environment.

Dynamic Groups and OCI IAM policies to access the code repository are missing.

The OKE cluster is not configured to allow external access to the code repository.

CA bundle for Transport Layer Security (TLS) verification to download the build source during the build run is missing.

The error “unable to clone the repository” typically indicates that there is an authentication or authorization issue preventing access to the OCI Code Repository. In OCI DevOps, the build pipeline must have the appropriate permissions to access the code repository.
To allow the build pipeline to clone the repository, you need to set up Dynamic Groups and OCI IAM policies that provide the necessary permissions for the build runner to access the code repository.

FRAGE 41
What are the two items required to create a rule for the Oracle Cloud Infrastructure Events Service? (Choose two.)

Rule Conditions

Management Agent Cloud Service

Service Connector

Actions

Auth Token

FRAGE 42
As an engineer building and deploying applications using an OCI DevOps project, which two capabilities can help ensure the security and reliability of the code in the build and deployment pipelines? (Choose two.)

Using third-party tools like Ansible, Terraform, or OverOps to analyze code for security defects or bugs in code quality

Using Application Dependency Management (ADM) to identify security weaknesses in software applications by checking their dependencies

Using JIRA to track user stories and bug fixes in the development process

Using version control tools like Git or SVN to track and manage changes in the codebase

Using third-party tools like Sonatype, SonarQube, or OverOps to analyze code for security defects or bugs in code quality

Application Dependency Management (ADM) is a tool used to identify security weaknesses in software applications by analyzing their dependencies. Dependencies can often introduce vulnerabilities, and managing them properly is a critical part of ensuring application security.
Third-party tools like Sonatype and SonarQube can be used to analyze code for security defects or bugs in code quality. These tools help in identifying vulnerabilities, code smells, and other issues, which can improve the overall security and reliability of the code during the build process.

FRAGE 43
Which of the following is NOT considered a DevOps resource in the context of the OCI DevOps project service?

Environments

API integrations

Build pipelines

Code repositories

In the context of OCI DevOps project service, the key DevOps resources include:
Environments: These are used to represent deployment targets, such as Kubernetes clusters, compute instances, or functions.
Build pipelines: These automate the building, testing, and packaging of software.
Code repositories: These store source code for the application being built, providing version control and collaboration.
API integrations are not directly considered a DevOps resource in OCI DevOps projects. Instead, they facilitate communication and integration with other tools or services but do not represent a core component of DevOps projects like environments, build pipelines, or code repositories.
