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

IBM Cloud Pak for Integration (CP4I) v2021.2 relies on IBM Cloud Pak Foundational Services, which was previously known as IBM Common Services. Upgrading from the Extended Update Support (EUS) version (3.6.x) to a continuous delivery version (3.7.x or later) requires following IBM's recommended upgrade paths. The two valid options are:

Using IBM's provided script (Option D):

IBM provides a script specifically designed to upgrade Cloud Pak Foundational Services from an EUS version to a later continuous delivery (CD) version.

This script automates the necessary upgrade steps and ensures dependencies are properly handled.

IBM's official documentation includes the script download links and usage instructions.

Using the IBM Cloud Pak Foundational Services operator update button (Option E):

The IBM Cloud Pak Foundational Services operator in the OpenShift web console provides an update button that allows administrators to upgrade services.

This method is recommended by IBM for in-place upgrades, ensuring minimal disruption while moving from 3.6.x to a later version.

The upgrade process includes rolling updates to maintain high availability.

Option A (Click the Update button on the Details page of the common-services operand):

There is no direct update button at the operand level that facilitates the entire upgrade from EUS to CD versions.

The upgrade needs to be performed at the operator level, not just at the operand level.

Option B (Select the Update Common Services option from the Cloud Pak Administration Hub console):

The Cloud Pak Administration Hub does not provide a direct update option for Common Services.

Updates are handled via OpenShift or IBM’s provided scripts.

Option C (Use the OpenShift web console to change the operator channel from stable-v1 to v3):

Simply changing the operator channel does not automatically upgrade from an EUS version to a continuous delivery version.

IBM requires following specific upgrade steps, including running a script or using the update button in the operator.

The NamespaceScope operator is responsible for managing and automating permissions-based workload isolation in IBM Cloud Pak for Integration (CP4I) Foundational Services. It allows multiple namespaces to share common resources while maintaining controlled access, thereby enforcing isolation between workloads.

Enables namespace scoping, which helps define which namespaces have access to shared services.

Restricts access to specific components within an environment based on namespace policies.

Automates workload isolation by enforcing access permissions across multiple namespaces.

Ensures compliance with IBM Cloud security standards by providing a structured approach to multi-tenant deployments.

A. Operand Deployment Lifecycle Manager: Manages lifecycle and deployment of operands in IBM Cloud Paks but does not specifically handle workload isolation.

C. Node taints and pod tolerations: These are Kubernetes-level mechanisms to control scheduling of pods on nodes but do not directly automate permissions-based workload isolation.

In Red Hat OpenShift, installing OpenShift GitOps (based on ArgoCD) requires elevated cluster-wide permissions because the installation process:

Deploys Custom Resource Definitions (CRDs).

Creates Operators and associated resources.

Modifies cluster-scoped components like role-based access control (RBAC) policies.

Only a user with cluster-admin privileges can perform these actions, making cluster-admin the correct role for installing OpenShift GitOps.

Command to Install OpenShift GitOps:oc apply -f openshift-gitops-subscription.yaml

This operation requires cluster-wide permissions, which only the cluster-admin role provides.

Why the Other Options Are Incorrect?Option

Explanation

Correct?

A. cluster-operator

❌ Incorrect – No such default role exists in OpenShift. Operators are managed within namespaces but cannot install GitOps at the cluster level.

❌

C. admin

❌ Incorrect – The admin role provides namespace-level permissions, but GitOps requires cluster-wide access to install Operators and CRDs.

❌

D. operator

❌ Incorrect – This is not a valid OpenShift role. Operators are software components managed by OpenShift, but an operator role does not exist for installation purposes.

❌

Final Answer:✅ B. cluster-admin

In IBM Cloud Pak Foundational Services, the audit-syslog-service is responsible for receiving audit data and collecting application logs. This service ensures that security and compliance-related events are properly recorded and made available for analysis.

The audit-syslog-service is a key component of Cloud Pak's logging and monitoring framework, specifically designed to capture audit logs from various services.

It can forward logs to external SIEM (Security Information and Event Management) systems or centralized log collection tools for further analysis.

It helps organizations meet compliance and governance requirements by maintaining detailed audit trails.

Why is audit-syslog-service the correct answer?

A. logging service (Incorrect)

While Cloud Pak Foundational Services include a logging service, it is primarily for general application logging and does not specifically handle audit data collection.

C. systemd journal (Incorrect)

systemd journal is the default system log manager on Linux but is not the dedicated service for handling Cloud Pak audit logs.

D. fluentd service (Incorrect)

Fluentd is a log forwarding agent used for collecting and transporting logs, but it does not directly receive audit data in Cloud Pak Foundational Services. It can be used in combination with audit-syslog-service for log aggregation.

In IBM Cloud Pak for Integration (CP4I) v2021.2, which runs on Red Hat OpenShift, logging is handled using the OpenShift Logging Operator, which often utilizes Elasticsearch as the log storage backend.

For a highly available (HA) Elasticsearch cluster, the minimum number of nodes required is 3.

Elasticsearch uses a quorum-based system for cluster state management.

A minimum of three nodes ensures that the cluster can maintain a quorum in case one node fails.

HA requires at least two master-eligible nodes, and with three nodes, the system can elect a new master if the active one fails.

Replication across three nodes prevents data loss and improves fault tolerance.

Why Are 3 Elasticsearch Nodes Required for High Availability?Example Elasticsearch Deployment for HA:A standard HA Elasticsearch setup consists of:

3 master-eligible nodes (manage cluster state).

At least 2 data nodes (store logs and allow redundancy).

Optional client nodes (handle queries to offload work from data nodes).

Ensures HA by allowing Elasticsearch to withstand node failures without loss of cluster control.

Prevents split-brain scenarios, which occur when an even number of nodes (e.g., 2) cannot reach a quorum.

Recommended by IBM and Red Hat for OpenShift logging solutions.

Why Answer C (3) is Correct?

A. 1 → Incorrect

A single-node Elasticsearch deployment is not HA because if the node fails, all logs are lost.

B. 2 → Incorrect

Two nodes cannot form a quorum, meaning the cluster cannot elect a leader reliably.

This could lead to split-brain scenarios or a complete failure when one node goes down.

D. 7 → Incorrect

While a larger cluster (e.g., 7 nodes) improves scalability and performance, it is not the minimum requirement for HA.

Three nodes are sufficient for high availability.

In IBM Cloud Pak for Integration (CP4I) v2021.2, when new IBM MQ (Message Queue) containers are deployed, sensitive data such as passwords, credentials, and encryption keys must be securely injected into the container environment.

The correct Kubernetes object for storing and injecting sensitive data is a Secret.

Kubernetes Secrets securely store sensitive data

Secrets allow IBM MQ containers to retrieve authentication credentials (e.g., admin passwords, TLS certificates, and API keys) without exposing them in environment variables or config maps.

Unlike ConfigMaps, Secrets are encrypted and access-controlled, ensuring security compliance.

Used by IBM MQ Operator

When deploying IBM MQ in OpenShift/Kubernetes, the MQ operator references Secrets to inject necessary credentials into MQ containers.

Example:

Why is "Secret" the correct answer?apiVersion: v1

kind: Secret

metadata:

name: mq-secret

type: Opaque

data:

mq-password: bXlxYXNzd29yZA==

The MQ container can then access this mq-password securely.

Prevents hardcoding sensitive data

Instead of storing passwords directly in deployment files, using Secrets enhances security and compliance with enterprise security standards.

Why are the other options incorrect?❌ A. Replicator

The Replicator is responsible for synchronizing and replicating messages across MQ queues but does not store sensitive credentials.

❌ B. MQRegistry

The MQRegistry is used for tracking queue manager details but does not manage sensitive data injection.

It mainly helps with queue manager registration and configuration.

❌ C. DeploymentConfig

A DeploymentConfig in OpenShift defines how pods should be deployed but does not handle sensitive data injection.

Instead, DeploymentConfig can reference a Secret, but it does not store sensitive information itself.

When configuring OpenShift Logging with Kibana to retrieve logs for Cloud Pak for Integration (CP4I) applications, the correct index pattern to use is applications*.

Here’s why:

IBM Cloud Pak for Integration (CP4I) applications running on OpenShift generate logs that are stored in the Elasticsearch logging stack.

The standard OpenShift logging format organizes logs into different indices based on their source type.

The applications* index pattern is used to capture logs for applications deployed on OpenShift, including CP4I components.

Analysis of the options:

Option A (Incorrect – cp4i-*): There is no specific index pattern named cp4i-* for retrieving CP4I logs in OpenShift Logging.

*Option B (Correct – applications)**: This is the correct index pattern used in Kibana to retrieve logs from OpenShift applications, including CP4I components.

Option C (Incorrect – torn-*): This is not a valid OpenShift logging index pattern.

Option D (Incorrect – app-*): This index does not exist in OpenShift logging by default.
