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

When installing a new instance of IBM Cloud Pak for Integration (CP4I) Operations Dashboard, several prerequisites must be met. The correct answers are B and D based on IBM Cloud Pak for Integration v2021.2 requirements.

B. A pull secret from IBM Entitled Registry must exist in the namespace containing an entitlement key.

The IBM Entitled Registry hosts the necessary container images required for CP4I components, including Operations Dashboard.

Before installation, you must create a pull secret in the namespace where CP4I is installed. This secret must include your IBM entitlement key to authenticate and pull images.

Command to create the pull secret:

Correct Answers:oc create secret docker-registry ibm-entitlement-key \

--docker-server=cp.icr.io \

--docker-username=cp \

--docker-password= \

--namespace=

D. The vm.max_map_count sysctl setting on worker nodes must be higher than the operating system default.

The Operations Dashboard relies on Elasticsearch, which requires an increased vm.max_map_count setting for better performance and stability.

The default Linux setting (65530) is too low. It needs to be at least 262144 to avoid indexing failures.

To update this setting permanently, run the following command on worker nodes:

sudo sysctl -w vm.max_map_count=262144

IBM Reference: Elasticsearch System Requirements

A. For shared data, a storage class that provides ReadWriteOnce (RWO) access mode of at least 100 MB is required. (Incorrect)

While persistent storage is required, the Operations Dashboard primarily uses Elasticsearch, which typically requires ReadWriteOnce (RWO) or ReadWriteMany (RWX) block storage. However, the 100 MB storage requirement is incorrect, as Elasticsearch generally requires gigabytes of storage, not just 100 MB.

IBM Recommendation: Typically, Elasticsearch requires at least 10 GB of persistent storage for logs and indexing.

C. If the OpenShift Container Platform Ingress Controller pod runs on the host network, the default namespace must be labeled with network.openshift.io/controller-group: ingress to allow traffic to the Operations Dashboard. (Incorrect)

While OpenShift’s Ingress Controller must be configured correctly, this specific label requirement applies to some specific OpenShift configurations but is not a mandatory prerequisite for Operations Dashboard installation.

Instead, route-based access and appropriate network policies are required to allow ingress traffic.

E. For storing tracing data, a block storage class that provides ReadWriteMany (RWX) access mode and 10 IOPS of at least 10 GB is required. (Incorrect)

Tracing data storage does require persistent storage, but block storage does not support RWX mode in most environments.

Instead, file-based storage with RWX access mode (e.g., NFS) is typically used for OpenShift deployments needing shared storage.

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

IBM Cloud Pak for Integration (CP4I) v2021.2 Administration References:

In IBM Cloud Pak for Integration (CP4I) v2021.2, profiles define the resource allocation and configuration settings for deployed services. When creating a second medium-size profile, the system will allocate the resources according to the medium-size specifications, without affecting the first profile.

IBM Cloud Pak for Integration supports multiple profiles, each with its own resource allocation.

When a second medium-size profile is created, it is independently assigned the medium-size configuration without modifying the existing profiles.

This allows multiple services to run with similar resource constraints but remain separately managed.

Why Option B is Correct:

A. The first profile will be replaced by the second profile. → ❌ Incorrect

Creating a new profile does not replace an existing profile; each profile is independent.

C. The first profile will be re-configured with a medium size. → ❌ Incorrect

The first profile remains unchanged. A second profile does not modify or reconfigure an existing one.

D. The second profile will be configured with a large size. → ❌ Incorrect

The second profile will retain the specified medium size and will not be automatically upgraded to a large size.
