Key/value pairs in the ObjectStore
Key/value pairs in the ObjectStore
Properties of the Mule runtime flow object
Properties of the Mule runtime flow object
properties of the Mule runtime app object
properties of the Mule runtime app object
session variables
session variables
Suggested answer: A

Explanation:

An object store is a facility for storing objects in or across Mule applications. Mule runtime engine (Mule) uses object stores to persist data for eventual retrieval. Internally, Mule uses object stores in various filters, routers, and other message processors that need to store states between messages.

Object stores are available in all deployment targets. If you deploy your application to CloudHub, you can also use Object Store V2.

Correct answer is Key/value pair in Object store
