C1000-130 Exam Dumps : IBM Cloud Pak for Integration V2021.2 Administration

Before installing IBM Cloud Pak for Integration (CP4I) on an OpenShift Cluster, an administrator needs to verify that the cluster meets the infrastructure prerequisites such as CPU, memory, and overall resource availability.

The most effective way to check real-time resource utilization and capacity is by using the oc adm top nodes command.

This command provides a summary of CPU and memory usage for all nodes in the cluster.

It is part of the OpenShift administrator CLI (oc adm), which is designed for cluster-wide management.

The information is fetched from Metrics Server or Prometheus, giving accurate real-time data.

It helps administrators assess whether the cluster has sufficient resources to support CP4I deployment.

Why is oc adm top nodes the correct answer?Example usage:oc adm top nodes

Example Output:scss

worker-node-1 1500m 30% 8Gi 40%

worker-node-2 1200m 25% 6Gi 30%

Why the Other Options Are Incorrect?Option

Explanation

Correct?

A. Use the oc cluster status command to dump the node capacity and utilization statistics for all the nodes.

❌ Incorrect – The oc cluster status command does not exist in OpenShift CLI. Instead, oc status gives a summary of the cluster but does not provide node resource utilization.

❌

B. Use the oc get nodes -o wide command to obtain the capacity and utilization statistics of memory and compute of the nodes.

❌ Incorrect – The oc get nodes -o wide command only shows basic node details like OS, internal/external IPs, and roles. It does not display CPU or memory utilization.

❌

C. Use the oc describe nodes command to dump the node capacity and utilization statistics for all the nodes.

❌ Incorrect – The oc describe nodes command provides detailed information about a node, but not real-time resource usage. It lists allocatable resources but does not give current utilization stats.

❌

Final Answer:✅ D. Use the oc adm top nodes command to obtain the capacity and utilization statistics of memory and compute of the nodes.

IBM Cloud Pak for Integration (CP4I) v2021.2 Administration References:

During the installation of IBM Cloud Pak for Integration (CP4I), an initial admin password is automatically generated and securely stored in a Kubernetes secret called platform-auth-idp-credentials.

This secret is located in the ibm-common-services namespace, which is a central namespace used by IBM Cloud Pak Foundational Services to manage authentication, identity providers, and security.

The stored credentials are required for initial login to the IBM Cloud Pak platform and can be retrieved using OpenShift CLI (oc).

Retrieving the Initial Admin Password:To view the stored credentials, administrators can run the following command:

sh

Copy

oc get secret platform-auth-idp-credentials -n ibm-common-services -o jsonpath='{.data.admin_password}' | base64 --decode

This will decode and display the initial admin password.

A. platform-auth-idp-credentials in the IAM service installation folder (Incorrect)

The IAM (Identity and Access Management) service does store authentication-related configurations, but the admin password is specifically stored in a Kubernetes secret, not in a local file.

C. platform-auth-idp-credentials in the /sbin folder (Incorrect)

The /sbin folder is a system directory on Linux-based OSes, and IBM Cloud Pak for Integration does not store authentication credentials there.

D. platform-auth-idp-credentials in the master-node root folder (Incorrect)

IBM Cloud Pak stores authentication credentials securely within Kubernetes secrets, not directly in the root folder of the master node.

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.

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.
