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 : B

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.

Explanation of Incorrect Answers:

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.

In IBM Cloud Pak for Integration (CP4I) v2021.2, ensuring high availability (HA) requires certain components to maintain a quorum. A quorum is a mechanism where a majority of nodes or instances must agree on a state to prevent split-brain scenarios and ensure consistency.

Why 'Multi-instance Queue Manager' (A) Requires a Quorum?

IBM MQ Multi-instance Queue Manager is designed for high availability.

It runs in an active-standby configuration where a shared storage is required, and a quorum ensures that failover occurs correctly.

If the primary queue manager fails, quorum logic ensures that another instance assumes control without data corruption.

Why 'API Management (API Connect)' (B) Requires a Quorum?

API Connect operates in a distributed cluster architecture where multiple components (such as the API Manager, Analytics, and Gateway) work together.

A quorum is required to ensure consistency and avoid conflicts in API configurations across multiple instances.

API Connect uses MongoDB as its backend database, and MongoDB requires a replica set quorum for high availability and failover.

Why Not the Other Options?

Option

Reason for Exclusion

C . Application Integration (App Connect)

While App Connect can be deployed in HA mode, it does not require a quorum. It uses Kubernetes scaling and load balancing instead.

D . Event Gateway Service

Event Gateway is stateless and relies on horizontal scaling rather than quorum-based HA.

E . Automation Assets

This component stores automation-related assets but does not require quorum for HA. It typically relies on persistent storage replication.

Thus, Multi-instance Queue Manager (IBM MQ) and API Management (API Connect) require quorum to ensure high availability in Cloud Pak for Integration.

Answer : B

IBM provides a publicly available document that lists the known issues, limitations, and restrictions for each release of IBM Cloud Pak for Integration (CP4I). This document is called 'IBM Cloud Pak for Integration - Known Limitations.'

It details any functional restrictions, unresolved issues, and workarounds applicable to the current and previous versions of CP4I.

This document helps administrators and developers understand current limitations before deploying or upgrading CP4I components.

It is updated regularly as IBM identifies new issues or resolves existing ones.

Analysis of Incorrect Options:

A . IBM Cloud Pak for Integration - Q&A (Incorrect)

A Q&A section typically contains frequently asked questions (FAQs) but does not specifically focus on known issues or limitations.

C . IBM Cloud Pak for Integration - Known Problems (Incorrect)

IBM does not maintain a document explicitly titled 'Known Problems.' Instead, known issues are included under 'Known Limitations.'

D . IBM Cloud Pak for Integration - Latest News (Incorrect)

The 'Latest News' section typically covers new features, updates, and release announcements, but it does not provide a dedicated list of limitations or unresolved issues.

Answer : D

In IBM Cloud Pak for Integration (CP4I) v2021.2, BAR (Broker Archive) files are used to package message flows, message models, and other resources for IBM App Connect Enterprise (ACE) deployments. These BAR files must be stored in a persistent storage volume to ensure they remain available across pod restarts and upgrades.

When setting up the ACE Dashboard, the storage type must be defined during the initial configuration. Once the Dashboard is created, the selected storage type cannot be changed without recreating the Dashboard. This is because the storage configuration is tied to the deployment and affects how BAR files are managed and accessed.

Option A (Persistent-claim storage is required): Incorrect, because while persistent storage is commonly used, the requirement depends on the deployment configuration. ACE supports ephemeral storage as well.

Option B (The storage type can be changed after the Dashboard is created): Incorrect, as the storage type is fixed after creation.

Option C (The BAR files must be stored in a volume in the container's file system): Incorrect, as ACE supports different storage options, including persistent volumes.

Option D (The storage type cannot be changed after Dashboard is created): Correct, because the storage configuration is immutable after creation.
