Question 2 of 160
What does to the attributes of a Mule event happen in a flow after an outbound HTTP Request is made?
Answer

Suggested Answer

The suggested answer is C.

When an outbound HTTP Request is made in a Mule flow, the attributes of the Mule event are replaced with new attributes from the HTTP Request response. These attributes include HTTP headers and other metadata related to the HTTP response. This ensures that the Mule event contains the latest information obtained from the outbound request response.

Question 3 of 160
The new RAML spec has been published to Anypoint Exchange with client credentials.
What is the next step to gain access to the API?
Answer

Suggested Answer

The suggested answer is D.

To gain access to the API published to Anypoint Exchange with client credentials, you need to request access to the API in Anypoint Exchange. This is because with client credential protection, an approval process is required, meaning the API owner needs to grant access permissions to the requesting client application.

Question 4 of 160
What is the difference between a subflow and a sync flow?
Answer

Suggested Answer

The suggested answer is A.

A sync flow has no error handling of its own and relies on the main flow or the parent flow to handle errors, whereas a subflow can have its own error handling. The key difference lies in how errors are managed between these two types of flows.

Question 5 of 160
What is not an asset?
Answer

Suggested Answer

The suggested answer is A.

An asset is typically a resource or item of value that can be utilized in some capacity. In the context of platforms like Mulesoft's Anypoint Exchange, assets include resources like templates, examples, and connectors because they provide distinct, usable content. An 'Exchange' itself, however, is a platform or repository where these assets are hosted and shared. Therefore, 'Exchange' is not considered an asset; it is the place where assets are stored and accessed.
