Answer : B, C

IBM Cloud Pak for Integration (CP4I) v2021.2 is designed to run on containerized environments that support Red Hat OpenShift, which can be deployed on various public clouds and on-premises environments. The two correct options that support CP4I deployments are:

Correct Answers:

Amazon Web Services (AWS) (Option B)

AWS supports IBM Cloud Pak for Integration via Red Hat OpenShift on AWS (ROSA) or self-managed OpenShift clusters running on AWS EC2 instances.

CP4I components such as API Connect, App Connect, MQ, and Event Streams can be deployed on OpenShift running on AWS.

Microsoft Azure (Option C)

Azure supports CP4I through Azure Red Hat OpenShift (ARO) or self-managed OpenShift clusters.

CP4I workloads can run efficiently on Azure's Kubernetes Service (AKS) when integrated with OpenShift.

Incorrect Answers:

Option

Explanation

Correct?

A . IBM Cloud Code Engine

Incorrect -- IBM Cloud Code Engine is a serverless platform designed for containerized applications and functions, but it does not support full-fledged OpenShift-based CP4I deployments.

D . IBM Cloud Foundry

Incorrect -- IBM Cloud Foundry is a Platform-as-a-Service (PaaS) that does not support OpenShift-based deployments, making it incompatible with CP4I.

E . Docker

Incorrect -- While CP4I components use containerized workloads, they require OpenShift or Kubernetes for orchestration, not just standalone Docker.

Final Answer:

B. Amazon Web Services C. Microsoft Azure

Answer : B

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 -c <container_name>

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.

Answer : A

In IBM Cloud Pak for Integration (CP4I) v2021.2, when deploying a highly available single-resilient queue manager, storage considerations are crucial to ensuring fault tolerance and failover capability.

A single-resilient queue manager uses a shared file system that allows different queue manager instances to access the same data, enabling failover to another node in the event of failure. The key requirement is data write integrity, ensuring that only one instance has access at a time and that locks are properly released in case of a node failure.

Option A is correct: A shared file system must support data consistency and failover mechanisms to ensure that only one instance writes to the queue manager logs and data at any time. If the active instance fails, another instance can take over using the same storage.

Option B is incorrect: While cloud storage replication across availability zones is useful, it does not replace the need for a proper shared file system with write integrity.

Option C is incorrect: Persistent volumes are supported for resilient queue managers when deployed in Kubernetes environments like OpenShift, as long as they meet the required file system properties.

Option D is incorrect: A single resilient queue manager can recover quickly by failing over to a standby node, often faster than a multi-instance queue manager, which requires additional failover processes.

Answer : A

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.

Why Option A (Unencrypted Private Key) is Correct:

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.

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.

Explanation of Incorrect Answers:

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.

Answer : B

OpenShift Pipelines, which are based on Tekton, use various components to define and execute CI/CD workflows. The fundamental building block for creating a Pipeline in OpenShift Pipelines is a Task.

Key Tekton Components:

Task ( Correct Answer)

A Task is the basic unit of work in Tekton.

Each Task defines a set of steps (commands) that are executed in containers.

Multiple Tasks are combined into a Pipeline to form a CI/CD workflow.

Pipeline (uses multiple Tasks)

A Pipeline is a collection of Tasks that define the entire CI/CD workflow.

Each Task in the Pipeline runs in sequence or in parallel as specified.

Why the Other Options Are Incorrect?

Option

Explanation

Correct?

A .TaskRun

Incorrect -- A TaskRun is an execution instance of a Task, but it does not define the Pipeline itself.

C . TPipe

Incorrect -- No such Tekton component called TPipe exists.

D . Pipe

Incorrect -- The correct term is Pipeline, not 'Pipe'. OpenShift Pipelines do not use this term.

Final Answer:

B . Task

Answer : A

In IBM Cloud Pak for Integration (CP4I), the Integration Runtimes page in the Platform Navigator provides an overview of available and deployable runtime components, such as IBM MQ, DataPower, API Connect, and Aspera.

When users see the message:

'Some runtimes cannot be created yet'

It typically indicates that one or more required operators have not been deployed. Each integration runtime requires its respective operator to be installed and running in order to create and manage instances of that runtime.

Key Reasons for This Issue:

If the Aspera, DataPower, or MQ operators are missing, then their corresponding runtimes will not be available in the Platform Navigator.

The Platform Navigator relies on these operators to manage the lifecycle of integration components.

Even if users have the necessary permissions, without the required operators, the integration runtimes cannot be provisioned.

Why Other Options Are Incorrect:

B . The platform navigator operator has not been installed cluster-wide

The Platform Navigator does not need to be installed cluster-wide for runtimes to be available.

If the Platform Navigator was missing, users would not even be able to access the Integration Runtimes page.

C . The ibm-entitlement-key has not been added in the same namespace as the platform navigator

The IBM entitlement key is required for pulling images from IBM's container registry but does not affect the visibility of Integration Runtimes.

If the entitlement key were missing, installation of operators might fail, but this does not directly cause the displayed message.

D . The API Connect operator has not been deployed

While API Connect is a component of CP4I, its operator is not required for all integration runtimes.

The error message suggests multiple runtimes are unavailable, which means the issue is more likely related to multiple missing operators, such as Aspera, DataPower, or MQ.

Answer : A

When installing IBM Cloud Pak for Integration (CP4I) on an OpenShift cluster that lacks internet access, an air-gapped installation is required. This process involves mirroring container images from an IBM container registry to a portable registry that can be accessed by the disconnected OpenShift cluster.

To authenticate and mirror images, the administrator must:

Use the cloudctl case command to configure credentials, including the IBM entitlement key, before initiating the mirroring process.

Authenticate with the IBM Container Registry using the entitlement key.

Mirror the required images from IBM's registry to a local registry that the disconnected OpenShift cluster can access.

Why Other Options Are Incorrect:

B . export ENTITLEMENTKEY and cloudPakOfflineInstaller -mirror-images

The command cloudPakOfflineInstaller -mirror-images is not a valid IBM Cloud Pak installation step.

IBM requires the use of cloudctl case commands for air-gapped installations.

C . Adding the entitlement key to .airgap/registries

There is no documented requirement to store the entitlement key in SHOME/.airgap/registries.

IBM Cloud Pak for Integration does not use this file for authentication.

D . Adding the ibm-entitlement-key as a Docker secret

While secrets are used in OpenShift for image pulling, they are not directly involved in mirroring images for air-gapped installations.

The entitlement key is required at the mirroring step, not when deploying the images.
