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

In IBM API Connect, which is part of IBM Cloud Pak for Integration (CP4I), the Management subsystem requires block storage with ReadWriteOnce (RWO) access mode.

The API Connect Management subsystem handles API lifecycle management, analytics, and policy enforcement.

It requires high-performance, low-latency storage, which is best provided by block storage.

The RWO (ReadWriteOnce) access mode ensures that each persistent volume (PV) is mounted by only one node at a time, preventing data corruption in a clustered environment.

Why "RWO Block Storage" is Required?Common Block Storage Options for API Connect on OpenShift:

Why the Other Options Are Incorrect?Option

Explanation

Correct?

A. NFS

❌ Incorrect – Network File System (NFS) is a shared file storage (RWX) and does not provide the low-latency performance needed for the Management subsystem.

❌

B. RWX block storage

❌ Incorrect – RWX (ReadWriteMany) block storage is not supported because it allows multiple nodes to mount the volume simultaneously, leading to data inconsistency for API Connect.

❌

D. GlusterFS

❌ Incorrect – GlusterFS is a distributed file system, which is not recommended for API Connect’s stateful, performance-sensitive components.

❌

Final Answer:✅ C. RWO block 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.

When installing IBM Cloud Pak for Integration (CP4I) operators via the CLI, the Operator Lifecycle Manager (OLM) requires an OperatorGroup resource before applying a Subscription.

OperatorGroup defines the scope (namespace) in which the operator will be deployed and managed.

It ensures that the operator has the necessary permissions to install and operate in the specified namespace.

Without an OperatorGroup, the subscription for ibm-cp-integration cannot be applied, and the installation will fail.

Create a new namespace (if not already created):

Why an OperatorGroup is Required:Steps for CLI Installation:oc create namespace cp4i-namespace

Create the OperatorGroup YAML (e.g., operatorgroup.yaml):

apiVersion: operators.coreos.com/v1

kind: OperatorGroup

metadata:

name: cp4i-operatorgroup

namespace: cp4i-namespace

spec:

targetNamespaces:

- cp4i-namespace

Apply it using:

oc apply -f operatorgroup.yaml

Apply the Subscription YAML for ibm-cp-integration once the OperatorGroup exists.

B. The ibm-foundational-services operator and subscription

While IBM Foundational Services is required for some Cloud Pak features, its absence does not prevent the creation of an operator subscription.

C. The platform-navigator operator and subscription

Platform Navigator is an optional component and is not required before installing the ibm-cp-integration subscription.

D. The ibm-common-services namespace

The IBM Common Services namespace is used for foundational services, but it is not required for defining an operator subscription in a new namespace.
