IBM Updated C1000-130 Exam Questions and Answers by claire

IBM Cloud Pak for Integration (CP4I) is licensed based on Virtual Processor Cores (VPCs), and administrators must ensure that CP4I does not exceed the entitled number of VPCs when deployed on a shared OpenShift cluster.

One of the official methods to enforce license usage limits in CP4I is by setting the MaxLicenseDeployment environment variable in the CP4I Operator.

MaxLicenseDeployment is an environment variable that can be set in the CP4I operator.

This restricts the CP4I components to only consume the specified number of Virtual Processor Cores (VPCs), ensuring compliance with licensing terms.

The value assigned should be less than or equal to the entitled VPCs to prevent over-deployment.

How This Works:Configuration Example:To enforce a maximum VPC limit of 16, update the CP4I Operator's environment variables:

env:

- name: MaxLicenseDeployment

value: "16"

IBM officially recommends using MaxLicenseDeployment to enforce VPC limits.

It is a built-in mechanism for Cloud Pak licensing enforcement.

Ensures compliance without affecting other Cloud Paks running on the same OpenShift cluster.

Why Answer A is Correct?

B. VPCs are shared across all IBM Cloud Paks, so this is not necessary. → Incorrect

While VPCs are shared at the cluster level, IBM provides per-Pak license enforcement mechanisms like MaxLicenseDeployment.

Without setting limits, CP4I could consume more than its entitled VPCs.

C. Only deploy CP4I to a namespace enforced by Kubernetes CPU quota limits, where the limit is less than the VPCs of license entitlement. → Incorrect

Kubernetes CPU quotas control resource allocation but do not enforce IBM licensing.

This does not track VPC consumption for licensing compliance.

D. More information is required. → Incorrect

The IBM licensing model is well-documented, and IBM provides clear guidance on using MaxLicenseDeployment.

No additional information is needed to determine the best approach.

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.
