At ValidExamDumps, we consistently monitor updates to the IBM C1000-130 exam questions by IBM. Whenever our team identifies changes in the exam questions,exam objectives, exam focus areas or in exam requirements, We immediately update our exam questions for both PDF and online practice exams. This commitment ensures our customers always have access to the most current and accurate questions. By preparing with these actual questions, our customers can successfully pass the IBM Cloud Pak for Integration V2021.2 Administration exam on their first attempt without needing additional materials or study guides.
Other certification materials providers often include outdated or removed questions by IBM in their IBM C1000-130 exam. These outdated questions lead to customers failing their IBM Cloud Pak for Integration V2021.2 Administration exam. In contrast, we ensure our questions bank includes only precise and up-to-date questions, guaranteeing their presence in your actual exam. Our main priority is your success in the IBM C1000-130 exam, not profiting from selling obsolete exam questions in PDF or Online Practice Test.
An administrator is checking that all components and software in their estate are licensed. They have only purchased Cloud Pak for Integration (CP41) li-censes.
How are the OpenShift master nodes licensed?
In IBM Cloud Pak for Integration (CP4I) v2021.2, licensing is based on Virtual Processor Cores (VPCs), and it includes entitlement for OpenShift usage. However, OpenShift master nodes (control plane nodes) do not consume license entitlement, because:
OpenShift licensing only applies to worker nodes.
The master nodes (control plane nodes) manage cluster operations and scheduling, but they do not run user workloads.
IBM's Cloud Pak licensing model considers only the worker nodes for licensing purposes.
Master nodes are essential infrastructure and are excluded from entitlement calculations.
IBM and Red Hat do not charge for OpenShift master nodes in Cloud Pak deployments.
Explanation of Incorrect Answers:
A . CP4I licenses include entitlement for the entire OpenShift cluster that they run on, and the administrator can count against the master nodes. Incorrect
CP4I licenses do cover OpenShift, but only for worker nodes where workloads are deployed.
Master nodes are excluded from licensing calculations.
C . The administrator will need to purchase additional OpenShift licenses to cover the master nodes. Incorrect
No additional OpenShift licenses are required for master nodes.
OpenShift licensing only applies to worker nodes that run applications.
D . CP4I licenses include entitlement for 3 cores of OpenShift per core of CP4I. Incorrect
The standard IBM Cloud Pak licensing model provides 1 VPC of OpenShift for 1 VPC of CP4I, not a 3:1 ratio.
Additionally, this applies only to worker nodes, not master nodes.

Which option should an administrator choose if they need to run Cloud Pak for Integration (CP4I) on AWS but do not want to have to manage the OpenShift layer themselves?
When deploying IBM Cloud Pak for Integration (CP4I) v2021.2 on AWS, an administrator has multiple options for managing the OpenShift layer. However, if the goal is to avoid managing OpenShift manually, the best approach is to deploy CP4I onto AWS ROSA (Red Hat OpenShift Service on AWS).
Why is AWS ROSA the Best Choice?
Managed OpenShift: ROSA is a fully managed OpenShift service, meaning AWS and Red Hat handle the deployment, updates, patching, and infrastructure maintenance of OpenShift.
Simplified Deployment: Administrators can directly deploy CP4I on ROSA without worrying about installing and maintaining OpenShift on AWS manually.
IBM Support: IBM Cloud Pak solutions, including CP4I, are certified to run on ROSA, ensuring compatibility and optimized performance.
Integration with AWS Services: ROSA allows seamless integration with AWS-native services like S3, RDS, and IAM for authentication and storage.
Why Not the Other Options?
B . Installer-provisioned Infrastructure on EC2 -- This requires manual setup of OpenShift on AWS EC2 instances, increasing operational overhead.
C . CP4I Quick Start on AWS -- IBM provides a Quick Start guide for deploying CP4I, but it assumes you are managing OpenShift yourself. This does not eliminate OpenShift management.
D . Terraform scripts from IBM's GitHub -- These scripts help automate provisioning but still require the administrator to manage OpenShift themselves.
Thus, for a fully managed OpenShift solution on AWS, AWS ROSA is the best option.

What is one way to obtain the OAuth secret and register a workload to Identity and Access Management?
In IBM Cloud Pak for Integration (CP4I) v2021.2, workloads requiring authentication with Identity and Access Management (IAM) need an OAuth secret for secure access. One way to obtain this secret and register a workload is through the OperandConfig API file.
Why Option D is Correct:
OperandConfig API is used in Cloud Pak for Integration to configure operands (software components).
It provides a mechanism to retrieve secrets, including the OAuth secret necessary for authentication with IBM IAM.
The OAuth secret is stored in a Kubernetes secret, and OperandConfig API helps configure and retrieve it dynamically for a registered workload.
Explanation of Incorrect Answers:
A . Extracting the ibm-entitlement-key secret. Incorrect
The ibm-entitlement-key is used for entitlement verification when pulling IBM container images from IBM Container Registry.
It is not related to OAuth authentication or IAM registration.
B . Through the Red Hat Marketplace. Incorrect
The Red Hat Marketplace is for purchasing and deploying OpenShift-based applications but does not provide OAuth secrets for IAM authentication in Cloud Pak for Integration.
C . Using a Custom Resource Definition (CRD) file. Incorrect
CRDs define Kubernetes API extensions, but they do not directly handle OAuth secret retrieval for IAM registration.
The OperandConfig API is specifically designed for managing operand configurations, including authentication details.

Which CLI command will retrieve the logs from a pod?
In IBM Cloud Pak for Integration (CP4I) v2021.2, which runs on Red Hat OpenShift, administrators often need to retrieve logs from pods to diagnose issues or monitor application behavior. The correct OpenShift CLI (oc) command to retrieve logs from a specific pod is:
sh
CopyEdit
oc logs
This command fetches the logs of a running container within the specified pod. If a pod has multiple containers, the -c flag is used to specify the container name:
sh
CopyEdit
oc logs
Explanation of Other Options:
A . oc get logs Incorrect. The oc get command is used to list resources (such as pods, deployments, etc.), but it does not retrieve logs.
C . oc describe Incorrect. This command provides detailed information about a pod, including events and status, but not logs.
D . oc retrieve logs Incorrect. There is no such command in OpenShift CLI.

Which Kubernetes resource can be queried to determine if the API Connect op-erator installation has a status of 'succeeded?
In IBM Cloud Pak for Integration (CP4I) v2021.2, when installing the API Connect Operator, it is crucial to monitor its deployment status to ensure a successful installation. This is typically done using ClusterServiceVersion (CSV), which is a Kubernetes resource managed by the Operator Lifecycle Manager (OLM).
The ClusterServiceVersion (CSV) represents the state of an operator and provides details about its installation, upgrades, and available APIs. The status field within the CSV object contains the installation progress and indicates whether the installation was successful (Succeeded), is still in progress (Installing), or has failed (Failed).
To query the status of the API Connect operator installation, you can run the following command:
kubectl get csv -n <namespace>
or
kubectl describe csv
This command will return details about the CSV, including its 'Phase', which should be 'Succeeded' if the installation is complete.
Why Other Options Are Incorrect:
A . The API Connect InstallPlan -- While the InstallPlan is responsible for tracking the installation process of the operator, it does not explicitly indicate whether the installation was completed successfully.
C . The API Connect Operator Subscription -- The Subscription resource ensures that the operator is installed and updated, but it does not provide a direct success or failure status of the installation.
D . The API Connect Operator Pod -- Checking the Pod status only shows if the Operator is running but does not confirm whether the installation process itself was completed successfully.
