Previous attributes are passed unchanged.

New attributes may be added from the HTTP response headers, but no headers are ever removed.

Correct Answer: C

Request access to the API in Anypoint Exchange.

Correct Answer: 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.

Question 4 of 155

What is the difference between a subflow and a sync flow?

A.

Sync flow has no error handling of its own and subflow does.

B.

Subflow has no error handling of its own and sync flow does.

C.

Subflow is synchronous and sync flow is asynchronous.

D.

No difference.

Correct Answer: 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 155

What is not an asset?

A.

Exchange

B.

Template

C.

Example

D.

Connector

Correct Answer: 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.
