Why would an administrator run the apic apic-config: get Portal CLI command?

Correct Answer: A
Explanation

An administrator would run the apic apic-config: get Portal CLI command to view the configured user registries, payment methods, permissions, and TLS profiles for the Portal. This command provides a comprehensive overview of the Portal's configuration settings, allowing the administrator to verify and modify them as needed.

How can a user be added that was previously removed from a Provider organization that uses a Local User Registry (LUR)?

Correct Answer: C
Explanation

To add a user that was previously removed from a Provider organization that uses a Local User Registry (LUR), the user must re-register using the invitation link sent by the Provider organization owner or a user with the appropriate role. This ensures that the user is added back to the organization with the correct permissions and settings.

Using the API Manager Ul, which two pieces of information can be viewed from the subscriptions in a Product?

Correct Answer: A, B
Explanation

Using the API Manager UI, you can view the following two pieces of information from the subscriptions in a Product:

The Plan that the application is subscribed to: This information tells you which specific plan the application is using to access the APIs in the Product.

The Product that contains the Plan that the application is subscribed to: This information shows you the overall Product that the application is subscribed to, which includes the Plan and associated APIs.

While you cannot directly view the spaces or catalogs where the subscribing Product is published from the subscriptions list, you can find this information by navigating to the Product itself and examining its properties.

How can a Consumer see their API usage?

Correct Answer: B
Explanation

In IBM API Connect v10.0.3, consumers can see their API usage on their application page within the Developer Portal. This page provides details about the number of requests made by their application to different APIs, allowing consumers to monitor their API consumption directly. This feature helps consumers track their usage metrics without needing to keep track themselves or request reports from the API provider.

Other options are incorrect:

Option A: The calling application does not need to track API usage manually.

Option C: Consumers are not typically given access to the API Manager analytics directly.

Option D: API providers do not need to generate a separate report; usage details are automatically available to consumers.

The DevOps team would like to incorporate API unit testing into the build and deploy step.

What could the API Connect Test application create to allow unit testing of their APIs?

Correct Answer: C
Explanation

The API Connect Test application can create mock tests to allow unit testing of APIs. Mock tests simulate the behavior of real APIs, allowing developers to test their code in isolation without relying on external dependencies. This can help to improve the quality and reliability of APIs.

In which two places can the rate limit for an API be defined?

Correct Answer: A, C
Explanation

In IBM API Connect v10.0.3, rate limiting for APIs can be defined in two primary places: Plan and Catalog.

Plan: Rate limiting is typically defined at the Plan level. A Plan in API Connect specifies how an API or a group of APIs is exposed to consumers. It can include rate limits, quotas, and other restrictions. Defining rate limits at the plan level ensures that each application subscribed to the plan adheres to the specified API consumption limits, such as the number of API calls allowed within a given time period.

Catalog: The Catalog is another place where rate limits can be defined. A Catalog represents a collection of APIs and their configurations, including security and rate limiting policies. Rate limits defined at the Catalog level apply globally to all APIs and applications within that Catalog, providing an overarching control mechanism to enforce consumption limits across different APIs.

These two locations allow flexibility in controlling API usage, either by restricting usage per plan (at a more granular level) or globally across all APIs within a catalog.

Which component enforces runtime policies to secure and control API traffic?

Correct Answer: D
Explanation

The API Gateway is responsible for enforcing runtime policies to secure and control API traffic. It acts as a central point of control for API requests, intercepting and analyzing them to apply security measures, rate limits, quotas, and other policies. This ensures that APIs are accessed and used in a secure and controlled manner.
