IBM Aspera High-Speed Transfer Server (HSTS) is a core component of IBM Cloud Pak for Integration (CP4I) that enables secure, high-speed file transfers over networks, regardless of file size, distance, or network conditions.

HSTS does not impose a file size limit, meaning users can transfer files of any size efficiently.

It uses IBM Aspera’s FASP (Fast and Secure Protocol) to achieve transfer speeds significantly faster than traditional TCP-based transfers, even over long distances or unreliable networks.

HSTS allows an unlimited number of concurrent users to transfer files using an Aspera client.

It ensures secure, encrypted, and efficient file transfers with features like bandwidth control and automatic retry in case of network failures.

A. HSTS allows an unlimited number of concurrent users to transfer files of up to 500GB at high speed using an Aspera client. (Incorrect)

Incorrect file size limit – HSTS supports files of any size without restrictions.

B. HSTS allows an unlimited number of concurrent users to transfer files of up to 100GB at high speed using an Aspera client. (Incorrect)

Incorrect file size limit – There is no 100GB limit in HSTS.

C. HSTS allows an unlimited number of concurrent users to transfer files of up to 1TB at high speed using an Aspera client. (Incorrect)

Incorrect file size limit – There is no 1TB limit in HSTS.

D. HSTS allows an unlimited number of concurrent users to transfer files of any size at high speed using an Aspera client. (Correct)

Correct answer – HSTS does not impose a file size limit, making it the best choice.

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.

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.

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.

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
