Refer to the exhibit. A Mule 4 application has a parent flow that breaks up a JSON array payload into 200 separate items, then sends each item one at a time inside an Async scope to a VM queue. A second flow to process orders has a VM Listener on the same VM queue. The rest of this flow processes each received item by writing the item to a database. This Mule application is deployed to four CloudHub workers with persistent queues enabled. What message processing guarantees are provided by the VM queue and the CloudHub workers, and how are VM messages routed among the CloudHub workers for each invocation of the parent flow under normal operating conditions where all the CloudHub workers remain online?
An ABC Farms project team is planning to build a new API that is required to work with data from different domains across the organization. The organization has a policy that all project teams should leverage existing investments by reusing existing APIs and related resources and documentation that other project teams have already developed and deployed. To support reuse, where on Anypoint Platform should the project team go to discover and read existing APIs, discover related resources and documentation, and interact with mocked versions of those APIs?
A Mule application uses the Database connector. What condition can the Mule application automatically adjust to or recover from without needing to restart or redeploy the Mule application?
A new Mule application under development must implement extensive data transformation logic. Some of the data transformation functionality is already available as external transformation services that are mature and widely used across the organization; the rest is highly specific to the new Mule application. The organization follows a rigorous testing approach, where every service and application must be extensively acceptance tested before it is allowed to go into production. What is the best way to implement the data transformation logic for this new Mule application while minimizing the overall testing effort?

A Mule application is deployed to a cluster of two(2) cusomter-hosted Mule runtimes. Currently the node name Alice is the primary node and node named bob is the secondary node. The mule application has a flow that polls a directory on a file system for new files. The primary node Alice fails for an hour and then restarted. After the Alice node completely restarts, from what node are the files polled, and what node is now the primary node for the cluster?
A banking company is developing a new set of APIs for its online business. One of the critical API's is a master lookup API which is a system API. This master lookup API uses persistent object store. This API will be used by all other APIs to provide master lookup data. Master lookup API is deployed on two cloudhub workers of 0.1 vCore each because there is a lot of master data to be cached. Master lookup data is stored as a key value pair. The cache gets refreshed if they key is not found in the cache. Doing performance testing it was observed that the Master lookup API has a higher response time due to database queries execution to fetch the master lookup data. Due to this performance issue, go-live of the online business is on hold which could cause potential financial loss to Bank. As an integration architect, which of the below option you would suggest to resolve performance issue?
