IBM Certified Administrator - Cloud Pak for Integration V2021.2 C1000-130 Full Course Free

When installing a new instance of IBM Cloud Pak for Integration (CP4I) Operations Dashboard, several prerequisites must be met. The correct answers are B and D based on IBM Cloud Pak for Integration v2021.2 requirements.

B. A pull secret from IBM Entitled Registry must exist in the namespace containing an entitlement key.

The IBM Entitled Registry hosts the necessary container images required for CP4I components, including Operations Dashboard.

Before installation, you must create a pull secret in the namespace where CP4I is installed. This secret must include your IBM entitlement key to authenticate and pull images.

Command to create the pull secret:

Correct Answers:oc create secret docker-registry ibm-entitlement-key \

--docker-server=cp.icr.io \

--docker-username=cp \

--docker-password= \

--namespace=

D. The vm.max_map_count sysctl setting on worker nodes must be higher than the operating system default.

The Operations Dashboard relies on Elasticsearch, which requires an increased vm.max_map_count setting for better performance and stability.

The default Linux setting (65530) is too low. It needs to be at least 262144 to avoid indexing failures.

To update this setting permanently, run the following command on worker nodes:

sudo sysctl -w vm.max_map_count=262144

IBM Reference: Elasticsearch System Requirements

A. For shared data, a storage class that provides ReadWriteOnce (RWO) access mode of at least 100 MB is required. (Incorrect)

While persistent storage is required, the Operations Dashboard primarily uses Elasticsearch, which typically requires ReadWriteOnce (RWO) or ReadWriteMany (RWX) block storage. However, the 100 MB storage requirement is incorrect, as Elasticsearch generally requires gigabytes of storage, not just 100 MB.

IBM Recommendation: Typically, Elasticsearch requires at least 10 GB of persistent storage for logs and indexing.

C. If the OpenShift Container Platform Ingress Controller pod runs on the host network, the default namespace must be labeled with network.openshift.io/controller-group: ingress to allow traffic to the Operations Dashboard. (Incorrect)

While OpenShift’s Ingress Controller must be configured correctly, this specific label requirement applies to some specific OpenShift configurations but is not a mandatory prerequisite for Operations Dashboard installation.

Instead, route-based access and appropriate network policies are required to allow ingress traffic.

E. For storing tracing data, a block storage class that provides ReadWriteMany (RWX) access mode and 10 IOPS of at least 10 GB is required. (Incorrect)

Tracing data storage does require persistent storage, but block storage does not support RWX mode in most environments.

Instead, file-based storage with RWX access mode (e.g., NFS) is typically used for OpenShift deployments needing shared storage.

Correct Ordered Steps to Delete IBM MQ from IBM Cloud Pak for Integration (CP4I):

1️⃣ Log in to your OpenShift cluster's web console.

Access the OpenShift web console to manage resources and installed operators.

2️⃣ Select Operators from Installed Operators in a project containing Queue Managers.

Navigate to the Installed Operators section and locate the IBM MQ Operator in the project namespace where queue managers exist.

3️⃣ Delete Queue Managers.

Before uninstalling the operator, delete any existing IBM MQ Queue Managers to ensure a clean removal.

4️⃣ Uninstall the Operator.

Finally, uninstall the IBM MQ Operator from OpenShift to complete the deletion process.

To properly delete IBM MQ from IBM Cloud Pak for Integration (CP4I), the steps must be followed in the correct order:

Logging into OpenShift Web Console – This step provides access to the IBM MQ Operator and related resources.

Selecting the Installed Operator – Ensures the correct project namespace and MQ resources are identified.

Deleting Queue Managers – Queue Managers must be removed before uninstalling the operator; otherwise, orphaned resources may remain.

Uninstalling the Operator – Once all resources are removed, the MQ Operator can be uninstalled cleanly.

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.

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.

Why Option D is Correct:

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.

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

In IBM Cloud Pak for Integration (CP4I) v2021.2, profiles define the resource allocation and configuration settings for deployed services. When creating a second medium-size profile, the system will allocate the resources according to the medium-size specifications, without affecting the first profile.

IBM Cloud Pak for Integration supports multiple profiles, each with its own resource allocation.

When a second medium-size profile is created, it is independently assigned the medium-size configuration without modifying the existing profiles.

This allows multiple services to run with similar resource constraints but remain separately managed.

Why Option B is Correct:

A. The first profile will be replaced by the second profile. → ❌ Incorrect

Creating a new profile does not replace an existing profile; each profile is independent.

C. The first profile will be re-configured with a medium size. → ❌ Incorrect

The first profile remains unchanged. A second profile does not modify or reconfigure an existing one.

D. The second profile will be configured with a large size. → ❌ Incorrect

The second profile will retain the specified medium size and will not be automatically upgraded to a large size.
