C1000-130 Exam Dumps : IBM Cloud Pak for Integration V2021.2 Administration

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 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.

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.
