Free IBM C1000-130 Practice Exam with Questions & Answers | Set: 4

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 IBM Cloud Pak for Integration (CP4I) v2021.2, when instantiating a new capability via the Platform Navigator, distributed tracing data is not automatically available. To enable tracing and observability for a capability, it must be registered with the Operations Dashboard.

The Operations Dashboard in CP4I provides centralized observability, logging, and distributed tracing across integration components.

Capabilities such as IBM API Connect, App Connect, IBM MQ, and Event Streams need to be explicitly registered with the Operations Dashboard to collect and display tracing data.

Registration links the capability with the distributed tracing service, allowing telemetry data to be captured.

Why "Register the capability with the Operations Dashboard" is the correct answer?

Why the Other Options Are Incorrect?Option

Explanation

Correct?

A. Press the 'enable' button in the Operations Dashboard.

❌ Incorrect – There is no single 'enable' button that automatically registers capabilities. Manual registration is required.

❌

B. Add 'operationsDashboard: true' to the deployment YAML.

❌ Incorrect – This setting alone does not enable distributed tracing. The capability still needs to be registered with the Operations Dashboard.

❌

C. Run the oc register command against the capability.

❌ Incorrect – There is no oc register command in OpenShift or CP4I for registering capabilities with the Operations Dashboard.

❌

Final Answer:✅ D. Register the capability with the Operations Dashboard

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.
