NEW QUESTION # 30
Which properties are mandatory on the HTTP Connector configuration in order to use the OAuth 2.0 Authorization Code grant type for authentication?
Answer: B
Explanation:
The OAuth 2.0 Authorization Code grant requires several endpoints and client credentials because the Mule application participates in both the user authorization stage and the subsequent authorization-code-to-token exchange.
For the HTTP Request Connector, MuleSoft identifies the principal required configuration fields as the external callback URL, local authorization URL, authorization URL, client ID, client secret, and token URL.
The option refers to the token endpoint as the access token URL, which represents the same OAuth server endpoint used to exchange the authorization code for an access token.
The authorization URL redirects the resource owner to the authorization server. The local authorization URL initiates Mule's authorization process. The external callback URL identifies the publicly reachable callback through which the OAuth server returns the authorization code. The client ID and client secret authenticate the registered client application, while the token URL is used for the token exchange.
By contrast, the local callback URL is configurable but not mandatory in the same manner, and fields such as Response Access Token and Response Refresh Token are expressions for extracting provider-specific values rather than fundamental mandatory authorization-code grant parameters.
Reference topics: HTTP Connector Authentication; OAuth 2.0 Authorization Code Grant; Callback URLs; Token Endpoint.

NEW QUESTION # 31
Which pattern should be used to invoke multiple HTTP APIs in parallel and roll back failed requests in sequence?
Answer: C
Explanation:
To invoke multiple HTTP APIs in parallel and roll back failed requests in sequence, the developer should use a Scatter-Gather router as a central Saga orchestrator for all API requests with compensating actions for failing routes. A Scatter-Gather router executes multiple routes concurrently and aggregates the results. A Saga orchestrator coordinates a series of actions across different services and handles failures by executing compensating actions. Therefore, using a Scatter-Gather router as a Saga orchestrator allows invoking multiple HTTP APIs in parallel and rolling back any failed requests in sequence.

NEW QUESTION # 32
Refer to the exhibit.
Based on the code snippet, schema,json file, and payload below, what is the outcome of the given code snippet when a request is sent with the payload?
Answer: D
Explanation:
Based on the code snippet, schema.json file, and payload below, the outcome of the given code snippet when a request is sent with the payload is that the Mule flow will throw the exception 'JSON:SCHEMA_NOT_HONOURED'. This is because the payload does not conform to the schema.json file, which specifies that age must be a number greater than or equal to zero. The payload has age as a string with a negative value, which violates the schema. Therefore, the validate-schema operation throws an error with type 'JSON:SCHEMA_NOT_HONOURED'. Reference: https://docs.mulesoft.com/json-module/1.1/json-validate-schema
NEW QUESTION # 33
A developer has created the first version of an API designed for business partners to work with commodity prices.
What should the developer do to allow more than one major version of the same API to be exposed by the implementation?
Answer: A
Explanation:
Major API versions should be distinguishable at the API's external URI rather than being encoded independently into every resource operation or into internal Mule flow names. MuleSoft recommends including the consumer-facing API version in the application URL, for example /v1/..., so clients can explicitly select the major API contract they intend to consume.
RAML supports this cleanly through the baseUri. A version variable can be included in the base URI, for example baseUri: https://api.example.com/v{version}, with the corresponding version or base URI parameter defined in the specification. This keeps the versioning concern at the API contract and endpoint-addressing level.
Changing every operation would unnecessarily duplicate version information. Modifying generated APIkit flow names affects Mule implementation internals but does not provide distinct public API addresses.
Similarly, manually changing generated HTTP listeners after scaffolding makes the implementation diverge from the API specification and weakens API-led lifecycle management.
MuleSoft's versioning guidance explicitly recommends exposing the major version in the API URL and using simple major identifiers such as v1, v2, and so forth.
Reference topics: API Versioning; RAML baseUri; Base URI Parameters; Major API Versions.

NEW QUESTION # 34
Refer to the exhibit.
What is the result of the Mule Maven Plugin configuration of the value of property tls.keystore.keyPassword in CloudHub 2.0?
Exhibit:
Answer: B
Explanation:
The Mule Maven Plugin's CloudHub 2.0 deployment configuration supports a top-level < secureProperties > element. Properties supplied through this element are treated differently from ordinary deployment properties:
CloudHub 2.0 encrypts their values before storing them.
MuleSoft's deployment documentation explicitly states that < secureProperties > is used to set application properties and instruct CloudHub 2.0 to encrypt the values before storing them. This is particularly appropriate for TLS credentials such as keystore passwords because these values should not be persisted as ordinary clear-text application configuration.
The important distinction is between encryption and UI masking. A masked field merely hides its visual representation; it does not by itself establish protected storage. In CloudHub 2.0, protected property values are stored securely and are not retrievable as plain values through Runtime Manager. Anypoint Studio is also not the component responsible for protecting a value supplied through the CloudHub deployment configuration, nor is this deferred to the Mule application's runtime flow.
Therefore, with the property placed under the Mule Maven Plugin's < secureProperties > configuration, CloudHub encrypts the value.
Reference topics: CloudHub 2.0 deployment; Mule Maven Plugin; secure properties; protected application configuration.
