Question 26

When the mule application using VM is deployed to a customer-hosted cluster or multiple cloudhub workers, how are messages consumed by the Mule engine?

A.the primary only in order to avoid duplicate processing
B.in non-deterministic way
C.by starting an XA transaction for each new message
D.in a deterministic way

Question 27

An external REST client periodically sends an array of records in a single POST request to a Mule application API endpoint.
The Mule application must validate each record of the request against a JSON schema before sending it to a downstream system in the same order that it was received in the array Record processing will take place inside a router or scope that calls a child flow. The child flow has its own error handling defined. Any validation or communication failures should not prevent further processing of the remaining records.
To best address these requirements what is the most idiomatic(used for it intended purpose) router or scope to used in the parent flow, and what type of error handler should be used in the child flow?

A.First Successful router in the parent flow
On Error Continue error handler in the child flow
B.For Each scope in the parent flow
On Error Continue error handler in the child flow
C.Parallel For Each scope in the parent flow
On Error Propagate error handler in the child flow
D.Until Successful router in the parent flow
On Error Propagate error handler in the child flow

Question 28

A global, high-volume shopping Mule application is being built and will be deployed to CloudHub. To improve performance, the Mule application uses a Cache scope that maintains cache state in a CloudHub object store. Web clients will access the Mule application over HTTP from all around the world, with peak volume coinciding with business hours in the web client's geographic location. To achieve optimal performance, what Anypoint Platform region should be chosen for the CloudHub object store?

A.Choose the same region as to where the Mule application is deployed
B.Choose the US-West region, the only supported region for CloudHub object stores
C.Choose the geographically closest available region for each web client
D.Choose a region that is the traffic-weighted geographic center of all web clients

Correct Answer: A

*Explanation:
CloudHub object store should be in same region where the Mule application is deployed. This will give optimal performance.
Before learning about Cache scope and object store in Mule 4 we understand what is in general Caching is and other related things.
WHAT DOES "CACHING" MEAN?
Caching is the process of storing frequently used data in memory, file system or database which saves processing time and load if it would have to be accessed from original source location every time.
In computing, a cache is a high-speed data storage layer which stores a subset of data, so that future requests for that data are served up faster than is possible by accessing the data's primary storage location. Caching allows you to efficiently reuse previously retrieved or computed data.
How does Caching work?
The data in a cache is generally stored in fast access hardware such as RAM (Random-access memory) and may also be used in correlation with a software component. A cache's primary purpose is to increase data retrieval performance by reducing the need to access the underlying slower storage layer.
Caching in MULE 4
In Mule 4 caching can be achieved in mule using cache scope and/or object-store. Cache scope internally uses Object Store to store the data.
What is Object Store
Object Store lets applications store data and states across batch processes, Mule components, and applications, from within an application. If used on cloud hub, the object store is shared between applications deployed on Cluster.
Cache Scope is used in below-mentioned cases:
* Need to store the whole response from the outbound processor
* Data returned from the outbound processor does not change very frequently
* As Cache scope internally handle the cache hit and cache miss scenarios it is more readable Object Store is used in below-mentioned cases:
* Need to store custom/intermediary data
* To store watermarks
* Sharing the data/stage across applications, schedulers, batch.
If CloudHub object store is in same region where the Mule application is deployed it will aid in fast access of data and give optimal performance.

Question 29

What API policy would LEAST likely be applied to a Process API?

A.Custom circuit breaker
B.Client ID enforcement

D.JSON threat protection

Question 30

What aspects of a CI/CD pipeline for Mute applications can be automated using MuleSoft-provided Maven plugins?

A.Compile, package, unit test, deploy, integration test
B.Compile, package, unit test, validate unit test coverage, deploy
C.Compile, package, unit test, deploy, create associated API instances in API Manager B Import from API designer, compile, package, unit test, deploy, publish to Am/point Exchange
