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

When replacing the default ingress certificate in IBM Cloud Pak for Integration (CP4I) v2021.2, one critical requirement is that the private key associated with the new certificate must be unencrypted.

OpenShift’s Ingress Controller (which CP4I uses) requires an unencrypted private key to properly load and use the custom TLS certificate.

Encrypted private keys would require manual decryption each time the ingress controller starts, which is not supported for automation.

The custom certificate and its key are stored in a Kubernetes secret, which already provides encryption at rest, making additional encryption unnecessary.

Why Option A (Unencrypted Private Key) is Correct:To apply a new custom certificate for ingress, the process typically involves:

Creating a Kubernetes secret containing the unencrypted private key and certificate:

sh

CopyEdit

oc create secret tls custom-ingress-cert \

--cert=custom.crt \

--key=custom.key -n openshift-ingress

Updating the OpenShift Ingress Controller configuration to use the new secret.

B. The certificate file must have only a single certificate. → ❌ Incorrect

The certificate file can contain a certificate chain, including intermediate and root certificates, to ensure proper validation by clients.

It is not limited to a single certificate.

C. The new certificate private key must be encrypted. → ❌ Incorrect

If the private key is encrypted, OpenShift cannot automatically use it without requiring a decryption passphrase, which is not supported for automated deployments.

D. The new certificate must be a self-signed certificate. → ❌ Incorrect

While self-signed certificates can be used, they are not mandatory.

Administrators typically use certificates from trusted Certificate Authorities (CAs) to avoid browser security warnings.

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.

IBM Common Services and Foundational Services Overview

In IBM Cloud Pak for Integration (CP4I), IBM MQ Native High Availability (NativeHA) is a feature that enables automated failover and redundancy by maintaining multiple replicas of an MQ queue manager.

When using NativeHA, licensing in CP4I is calculated based on the total number of VPCs (Virtual Processor Cores) consumed by all MQ instances, including both active and standby replicas.

IBM MQ NativeHA uses a multi-replica setup, meaning there are multiple queue manager instances running simultaneously for redundancy.

Licensing in CP4I is based on the total CPU consumption of all running MQ replicas, not just the active instance.

Therefore, the administrator must ensure that all HA replicas are accounted for in their license entitlement.

Why Option B is Correct:

A. No licenses, because only RDQM is supported on CP4I. (Incorrect)

IBM MQ NativeHA is fully supported on CP4I alongside RDQM (Replicated Data Queue Manager). NativeHA is actually preferred over RDQM in containerized OpenShift environments.

C. A different license from the standard CP4I license must be purchased from IBM to use the NativeHA feature. (Incorrect)

No separate license is required for NativeHA – it is covered under the CP4I licensing model.

D. The administrator can use their pool of CP4I licenses. (Incorrect)

Partially correct but incomplete – while the administrator can use their CP4I licenses, they must ensure that all HA replicas are included in the license calculation, not just the active instance.
