IBM C1000-130 Exam With Confidence Using Practice Dumps

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.

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.

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

In an IBM Cloud Pak for Integration (CP4I) v2021.2 deployment, certain components require ReadWriteMany (RWX) storage to allow multiple pods to read and write data concurrently.

CouchDB is used as the Asset Repository in CP4I to store configuration and metadata for IBM Automation Assets.

It requires persistent storage that can be accessed by multiple instances simultaneously.

RWX storage is necessary because multiple pods may need concurrent access to the same database storage in a distributed deployment.

Common RWX storage options in OpenShift include NFS, Portworx, or CephFS.

Why Option B (CouchDB for Asset Repository) is Correct:

A. MQ multi-instance → Incorrect

IBM MQ multi-instance queue managers require ReadWriteOnce (RWO) storage because only one active instance at a time can write to the storage.

MQ HA deployments typically use Replicated Data Queue Manager (RDQM) or Persistent Volumes with RWO access mode.

C. API Connect → Incorrect

API Connect stores most of its configurations in databases like MongoDB but does not specifically require RWX storage for its primary operation.

It uses RWO or ReadOnlyMany (ROX) storage for its internal components.

D. Event Streams → Incorrect

Event Streams (based on Apache Kafka) uses RWO storage for high-performance message persistence.

Each Kafka broker typically writes to its own dedicated storage, meaning RWX is not required.
