If the App Connect Operator is installed in a restricted network, which statement is true?

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.
