IBM C1000-130 Exam With Confidence Using Practice Dumps

The command executed is:

sh

oc get po

This command lists the pods running in an OpenShift (OCP) cluster where IBM API Connect is deployed.

Most API Connect management components (apic-dev-mgmt-xxx) are in a Running state, which indicates that the core API Connect system is operational.

The apic-dev-mgmt-turnstile pod is in a CrashLoopBackOff state, with 301 restarts, indicating that this component has repeatedly failed to start properly.

The Turnstile pod is a critical component of the IBM API Connect Developer Portal.

It manages authentication and access control for the Developer Portal, ensuring that API consumers can access the portal and manage API subscriptions.

When Turnstile is failing, the Developer Portal becomes unresponsive because authentication requests cannot be processed.

Key Observations from the Output:Understanding the Turnstile Component:

Since the Turnstile pod is failing, the Developer Portal will not function properly, preventing users from accessing API documentation and managing API subscriptions.

API providers and consumers will not be able to log in or interact with the Developer Portal.

Why Answer B is Correct?

A. The Analytics subsystem cannot retain historical data. → Incorrect

The Analytics-related pods (e.g., apic-dev-analytics-xxx) are in a Running state.

If the Analytics component were failing, metrics collection and historical API call data would be impacted, but this is not indicated in the output.

C. Automated API behavior testing has failed. → Incorrect

There is no evidence in the pod list that API testing-related components (such as test clients or monitoring tools) have failed.

D. New API calls will be rejected by the gateway service. → Incorrect

The gateway service is not shown as failing in the provided output.

API traffic flows through the Gateway pods (typically apic-gateway-xxx), and they appear to be running fine.

If gateway-related pods were failing, API call processing would be affected, but that is not the case here.

Open Tracing in IBM API Connect allows for distributed tracing of API calls across the system, helping administrators analyze performance bottlenecks and troubleshoot issues. However, this capability is specifically designed to work with APIs that utilize the API Gateway.

Option A (Correct Answer): IBM API Connect integrates with OpenTracing for API Gateway, allowing the tracing of API requests in the Operations Dashboard. This provides deep visibility into request flows and latencies.

Option B (Incorrect): API debug data is not directly made available in OpenShift cluster logging. Instead, API tracing data is captured using OpenTracing-compatible tools.

Option C (Incorrect): OpenTracing is available for all deployment profiles, including production, not just non-production environments.

Option D (Incorrect): Trace data is not directly visible in Analytics dashboards but rather in the Operations Dashboard where administrators can inspect API request traces.

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.
