Question 1

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

ACloud Manager

BAPI Manager

CDeveloper Portal

DAPI Gateway

Answer : D

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.

Question 2

What is a vanity API endpoint?

AThe server URL on which the API is running.

BThe basepath as defined in the OpenAPI definition for the API.

CThe gateway endpoint at which the API is invoked.

DThe endpoint that is visible to the Consumer in the Developer Portal.

Answer : D

A vanity API endpoint is the endpoint that is visible to the Consumer in the Developer Portal. It is a user-friendly and memorable endpoint that masks the underlying gateway endpoint where the API is actually invoked. Vanity endpoints provide a more convenient and intuitive way for Consumers to interact with APIs.

Question 3

A developer would like to run the step debugger on the Gatewayscript policy that is part of the Assembly.

What would allow step debugging on the Gatewayscript?

AAdd a debugger; statement.

BEnable step debug in the Test tab.

CClick the Trace in the Test tab.

DEnable debug checkbox in Assemble.

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.

Question 4

Which statement describes a requirement for monetizing a Product?

AAn administrator must have both soft and hard rates limits set for the API product.

BA billing integration resource must first be configured for the Provider organization.

CAny existing free plans for the Product must be disabled.

DThe Payment Cloud method module must be enabled in the Developer Portal.

Answer : B

To monetize a Product in API Connect, you must first configure a billing integration resource for the Provider organization. This resource defines the payment gateway or other payment method that will be used to process payments for API subscriptions. Once a billing integration resource is configured, you can create paid plans for your Products and enable billing for those plans.

Question 5

A developer is working on an API which supports the v5c-gateway and wants to also support the datapower-api-gateway.

Which statement is true about selecting a gateway?

AOnly one gateway type is allowed per API.

BDisabling enforce will allow multiple gateways.

CSelecting multiple gateways is accomplished in the API Manager.

DNo changes are needed to switch gateways.

Answer : A

In IBM API Connect, each API is associated with a specific gateway type, and only one gateway type is allowed per API. The v5c-gateway and datapower-api-gateway are different gateway types, and a single API cannot simultaneously support both types. If a developer wants to support multiple gateways, they must create separate APIs for each gateway type.

Question 6

Which statement is correct about migration of a subscribed external application to a new Product?

AA Community Manager manages migration of a subscribed external application to a new Product.

BThe admin of a Developer Portal can enforce the migration to a new Product.

CThe Consumer manages migration of their subscribed application to a new Product.

DThe Plans of the new product should be the same or less restrictive than those of the original Product.

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.

Question 7

A User registry was created in the Cloud Manager.

In order for the registry to be used on the Developer Portal, what must be completed?

AOn the appropriate Catalog, configure the Onboarding setting.

BOn the API Manager resources page, make the User registry public.

COn the Portal settings page, choose the User registry.

DOn the appropriate Catalog, configure the resources settings.

Answer : A

After creating a User registry in the Cloud Manager, it must be configured on the appropriate Catalog's Onboarding settings to be used on the Developer Portal in IBM API Connect v10.0.3. This configuration allows the User registry to authenticate and manage users effectively when they interact with the Developer Portal.

Other options are incorrect:

Option B: Making the User registry public on the API Manager resources page does not apply.

Option C: Configuring the Portal settings page is not sufficient for enabling the registry.

Option D: Configuring resources settings on the Catalog does not directly involve user registry onboarding.
