In IBM Aspera High-Speed Transfer Server (HSTS), UDP ports are crucial for enabling high-speed data transfers. When multiple instances of Aspera HSTS exist in a cluster, each instance must be assigned a unique UDP port to avoid conflicts and ensure proper traffic routing.

Aspera HSTS relies on UDP for high-speed file transfers (as opposed to TCP, which is typically used for control and session management).

If multiple HSTS instances share the same UDP port, packet collisions and routing issues can occur.

Ensuring unique UDP ports across instances allows for proper load balancing and optimal performance.

B. UDP and TCP ports have to be the same.

Incorrect, because UDP and TCP serve different purposes in Aspera HSTS.

TCP is used for session initialization and control, while UDP is used for actual data transfer.

C. Each TCP port must be unique.

Incorrect, because TCP ports do not necessarily need to be unique across multiple instances, depending on the deployment.

TCP ports can be shared if proper load balancing and routing are configured.

D. UDP ports must be the same.

Incorrect, because using the same UDP port for multiple instances causes conflicts, leading to failed transfers or degraded performance.

IBM Aspera High-Speed Transfer Overview

In IBM Cloud Pak for Integration (CP4I) v2021.2, when App Connect Operator is deployed in a restricted network (air-gapped environment), access to external cloud-based services (such as AWS S3) is typically not available.

A restricted network means no direct internet access, so external storage services like Amazon S3 cannot be used to store Broker Archive (BAR) files.

BAR files contain packaged integration flows for IBM App Connect Enterprise (ACE).

In restricted environments, administrators must use internal storage options, such as:

Persistent Volume Claims (PVCs)

Ephemeral storage (temporary, in-memory storage)

Why Option A (S3 Cannot Be Used) is Correct:

B. Ephemeral storage cannot be used for BAR files. → Incorrect

Ephemeral storage is supported but is not recommended for production because data is lost when the pod restarts.

C. Only Ephemeral storage is supported for BAR files. → Incorrect

Both Ephemeral storage and Persistent Volume Claims (PVCs) are supported for storing BAR files.

Ephemeral storage is not the only option.

D. Persistent Claim storage cannot be used for BAR files. → Incorrect

Persistent Volume Claims (PVCs) are a supported and recommended method for storing BAR files in a restricted network.

This ensures that integration flows persist even if a pod is restarted or redeployed.

Before installing IBM Cloud Pak for Integration (CP4I) on an OpenShift Cluster, an administrator needs to verify that the cluster meets the infrastructure prerequisites such as CPU, memory, and overall resource availability.

The most effective way to check real-time resource utilization and capacity is by using the oc adm top nodes command.

This command provides a summary of CPU and memory usage for all nodes in the cluster.

It is part of the OpenShift administrator CLI (oc adm), which is designed for cluster-wide management.

The information is fetched from Metrics Server or Prometheus, giving accurate real-time data.

It helps administrators assess whether the cluster has sufficient resources to support CP4I deployment.

Why is oc adm top nodes the correct answer?Example usage:oc adm top nodes

Example Output:scss

Copy

NAME CPU(cores) CPU% MEMORY(bytes) MEMORY%

worker-node-1 1500m 30% 8Gi 40%

worker-node-2 1200m 25% 6Gi 30%

Why the Other Options Are Incorrect?Option

Explanation

Correct?

A. Use the oc cluster status command to dump the node capacity and utilization statistics for all the nodes.

❌ Incorrect – The oc cluster status command does not exist in OpenShift CLI. Instead, oc status gives a summary of the cluster but does not provide node resource utilization.

❌

B. Use the oc get nodes -o wide command to obtain the capacity and utilization statistics of memory and compute of the nodes.

❌ Incorrect – The oc get nodes -o wide command only shows basic node details like OS, internal/external IPs, and roles. It does not display CPU or memory utilization.

❌

C. Use the oc describe nodes command to dump the node capacity and utilization statistics for all the nodes.

❌ Incorrect – The oc describe nodes command provides detailed information about a node, but not real-time resource usage. It lists allocatable resources but does not give current utilization stats.

❌

Final Answer:✅ D. Use the oc adm top nodes command to obtain the capacity and utilization statistics of memory and compute of the nodes.

When installing IBM Cloud Pak for Integration (CP4I) on an OpenShift cluster that lacks internet access, an air-gapped installation is required. This process involves mirroring container images from an IBM container registry to a portable registry that can be accessed by the disconnected OpenShift cluster.

To authenticate and mirror images, the administrator must:

Use the cloudctl case command to configure credentials, including the IBM entitlement key, before initiating the mirroring process.

Authenticate with the IBM Container Registry using the entitlement key.

Mirror the required images from IBM’s registry to a local registry that the disconnected OpenShift cluster can access.

B. export ENTITLEMENTKEY and cloudPakOfflineInstaller -mirror-images

The command cloudPakOfflineInstaller -mirror-images is not a valid IBM Cloud Pak installation step.

IBM requires the use of cloudctl case commands for air-gapped installations.

C. Adding the entitlement key to .airgap/registries

There is no documented requirement to store the entitlement key in SHOME/.airgap/registries.

IBM Cloud Pak for Integration does not use this file for authentication.

D. Adding the ibm-entitlement-key as a Docker secret

While secrets are used in OpenShift for image pulling, they are not directly involved in mirroring images for air-gapped installations.

The entitlement key is required at the mirroring step, not when deploying the images.
