Question No. 1

The GraphQL developer incorporated a field that should not be available for introspection or validation by the client.

How would the API developer obfuscate the field so clients will not view them?

Show Answer Hide Answer
Correct Answer: B

To obfuscate a field in a GraphQL schema so that it is not available for introspection or validation by the client, the API developer can apply the @hide directive to the field. This directive tells the GraphQL engine to exclude the field from the schema introspection and validation process, making it invisible to clients.

Other options are incorrect:

Option B: Linking the same Product and version inside different APIs does not apply.

Option C: Plans are linked to Products, not directly to APIs.

Question No. 5

Which statement is correct regarding the creation of a SOAP proxy API from an existing SOAP service?

Show Answer Hide Answer
Correct Answer: B

When creating a SOAP proxy API from an existing SOAP service in IBM API Connect, a key step is to upload a single .zip file that contains the WSDL (Web Services Description Language) file and any associated dependent documents. This enables IBM API Connect to understand the service definition and its dependencies, allowing it to create the proxy API correctly. This method is necessary to ensure all components required for the SOAP API are packaged together and recognized during the import process.
