IBM C1000-138 IBM API Connect v10.0.3 Solution Implementation Exam Practice Test

Answer : A

To enable step debugging on a GatewayScript policy in IBM API Connect v10.0.3, a developer must add a debugger; statement within the GatewayScript code. This statement serves as a breakpoint that will pause execution, allowing the developer to step through the code to identify and resolve issues.

Other options are incorrect:

Option B and D ('Enable step debug in the Test tab' and 'Enable debug checkbox in Assemble') do not enable the step debugger in GatewayScript.

Option C ('Click the Trace in the Test tab') allows tracing but not step debugging.

Answer : B

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.

Answer : A, E

In IBM API Connect v10.0.3, OpenID Connect (OIDC) is a widely used authentication mechanism that allows clients to verify the identity of users based on the authentication performed by an authorization server. API Connect supports various OIDC providers for portal access to integrate with third-party identity providers. Out of the box, API Connect v10.0.3 comes with support for Azure Active Directory (Azure AD) and IBM Cloud as pre-configured OIDC providers.

Azure AD is one of the most commonly used OIDC providers, especially in enterprise environments using Microsoft's cloud services.

IBM Cloud Identity and Access Management (IAM) also provides built-in OIDC support within the IBM ecosystem, making it a natural integration point for users of IBM Cloud services.

These built-in integrations simplify the configuration and management of OIDC providers without requiring additional custom configuration.

Answer : C

API Properties: In IBM API Connect, API properties are configuration settings that can be used to customize the behavior of APIs. These properties can be defined at various levels, including the API, Product, and Catalog levels.

Catalog-Specific Values: A property can be assigned a specific value for each Catalog. This allows for different configurations and behaviors of the same API when deployed in different Catalogs. For example, an API might have different endpoint URLs or security settings in development, testing, and production environments.

Runtime Changes: While some properties can be modified at runtime, this is not a general rule for all API properties. The ability to change property values at runtime depends on the specific property and its configuration.

Pre-defined Properties: API properties can be both pre-defined and custom-defined. Pre-defined properties are provided by IBM API Connect, while custom properties can be created by API developers to suit specific needs.

Spaces and Properties: If Spaces are enabled, properties can indeed have Space-specific values. This allows for further granularity in configuration, enabling different settings within the same Catalog based on the Space.

Answer : C

Consumer Responsibility: In IBM API Connect, the consumer (or developer) who has subscribed to an API Product is responsible for managing the migration of their subscribed application to a new Product. This ensures that the consumer has control over their application's dependencies and can test the new Product before fully migrating.

Migration Process: When a new Product is introduced, consumers need to subscribe to the new Product and update their application configurations to use the new API endpoints and plans. This process involves:

Reviewing the new Product's documentation and capabilities.

Testing the new Product in a staging environment.

Updating application code and configurations to point to the new Product's endpoints.

Subscribing to the new Product through the Developer Portal.

Role of Admins and Community Managers:

Admins: While the admin of a Developer Portal can facilitate the migration process by providing necessary tools and support, they do not enforce the migration.

Community Managers: They manage the overall community and can provide guidance, but the actual migration task is performed by the consumer.

Product Plans: The plans of the new Product do not necessarily have to be the same or less restrictive than those of the original Product. The new Product may offer different plans with varying levels of access and features.

Answer : A

Product Publication: In IBM API Connect, a Product is a collection of APIs and Plans that can be published to a Developer Portal. When publishing a Product, you have the option to select specific communities to which the Product will be available.

Selected Communities: This feature allows API providers to control access to their APIs by making them available only to certain groups or communities. This is useful for managing access based on different criteria such as user roles, subscription levels, or organizational units.

Staging vs. Publishing:

Staging: When a Product is staged, it is deployed to a staging environment where it can be tested and validated before being made publicly available.

Publishing: After successful staging, the Product can be published to the Developer Portal, making it accessible to the selected communities.

Accessibility of APIs: APIs within a Product become accessible to developers when the Product is published to the Developer Portal, not just when it is staged.

Visibility: The visibility of a Product is controlled by the API provider. It can be restricted to specific communities or made available to all, depending on the publication settings.

Answer : C

API Endpoint Structure: In IBM API Connect, the structure of an API endpoint URL typically includes the base URL, followed by the catalog name, and then the API name.

Catalog Name: The segment of the URL immediately following the base URL (in this case, ''savings'') is generally the name of the catalog to which the API is deployed. This is a default setting in IBM API Connect.

API Name: The last segment of the URL (in this case, ''annual'') is usually the name of the API being called.

Default Catalog Settings: With default catalog settings, the catalog name is included in the URL to distinguish between different catalogs. This helps in organizing and managing APIs across different environments or stages (e.g., development, testing, production).
