An API instance of type API endpoint with API proxy is created in API manager using an API specification from Anypoint Exchange. The API instance is also configured with an API proxy that is deployed and running in CloudHub.
An SLA- based policy is enabled in API manager for this API instance.
Where can an external API consumer obtain a valid client ID and client secret to successfully send requests to the API proxy?

A. In the organization's public API portal in Anypoint Exchange, from an approved client application for the API proxy

B. In Anypoint Studio, from components generated by APIkit for the API specification

C. In Anypoint Studio, from components generated by Rest Connect for API specification

D. In Runtime Manager, from the properties tab of the deployed approved API proxy

A. In the organization's public API portal in Anypoint Exchange, from an approved client application for the API proxy

Explanation:
* When a client application is registered in Anypoint Platform, a pair of credentials consisting of a client ID and client secret is generated.
* When the client application requests access to an API, a contract is created between the application and that API.
* An API that is protected with a Client ID Enforcement policy is accessible only to applications that have an approved contract.

All three of the conditions for the Choice router are true. What messages are written in the application log?

A. Route1

B. Route2

C. Route1,Route2

D. Route1,Route2,Default

A. Route1

Only one of the routes in the Choice router executes, meaning that the first expression that evaluates to true triggers that route1 execution and the others are not checked. If none of the expressions are true, then the default route executes. Hence only Route1 will be executed as it is the first expression. hence output of logger is Route1.
MuleSoft Doc Ref : https://docs.mulesoft.com/mule-runtime/4.3/choice-router-concept The Choice router dynamically routes messages through a flow according to a set of DataWeave expressions that evaluate message content. Each expression is associated with a different routing option. The effect is to add conditional processing to a flow, similar to an if/then/else code block in most programming languages.
Only one of the routes in the Choice router executes, meaning that the first expression that evaluates to true triggers that route’s execution and the others are not checked. If none of the expressions are true, then the default route executes.
