Question 40

An API has been updated in Anypoint exchange by its API producer from version 3.1.1 to 3.2.0 following accepted semantic versioning practices and the changes have been communicated via the APIs public portal. The API endpoint does NOT change in the new version. How should the developer of an API client respond to this change?

Options:

The API producer should be requested to run the old version in parallel with the new one

The API producer should be contacted to understand the change to existing functionality

The API client code only needs to be changed if it needs to take advantage of the new features

The API clients need to update the code on their side and need to do full regression

Question 41

Refer to the exhibit.

Questions 41

An organization uses one specific CloudHub (AWS) region for all CloudHub deployments.

How are CloudHub workers assigned to availability zones (AZs) when the organization's Mule applications are deployed to CloudHub in that region?

Options:

Workers belonging to a given environment are assigned to the same AZ within that region

AZs are selected as part of the Mule application's deployment configuration

Workers are randomly distributed across available AZs within that region

An AZ is randomly selected for a Mule application, and all the Mule application's CloudHub workers are assigned to that one AZ

Josephine

I want to ask about their study material and Customer support? Can anybody guide me?

Zayd Jul 29, 2025

Yes, the dumps or study material provided by them are authentic and up to date. They have a dedicated team to assist students and make sure they have a positive experience.

Ilyas

Definitely. I felt much more confident and prepared because of the Cramkey Dumps. I was able to answer most of the questions with ease and I think that helped me to score well on the exam.

Saoirse Jul 17, 2025

That's amazing. I'm glad you found something that worked for you. Maybe I should try them out for my next exam.

Pippa

I was so happy to see that almost all the questions on the exam were exactly what I found in their Dumps.

Anastasia Jul 11, 2025

You are right…It was amazing! The Cramkey Dumps were so comprehensive and well-organized, it made studying for the exam a breeze.

Lennie

I passed my exam and achieved wonderful score, I highly recommend it.

Emelia Jul 4, 2025

I think I'll give Cramkey a try next time I take a certification exam. Thanks for the recommendation!

Question 42

When designing an upstream API and its implementation, the development team has been advised to NOT set timeouts when invoking a downstream API, because that downstream API has no SLA that can be relied upon. This is the only downstream API dependency of that upstream API.

Assume the downstream API runs uninterrupted without crashing. What is the impact of this advice?

Options:

An SLA for the upstream API CANNOT be provided

The invocation of the downstream API will run to completion without timing out

A default timeout of 500 ms will automatically be applied by the Mule runtime in which the upstream API implementation executes

A toad-dependent timeout of less than 1000 ms will be applied by the Mule runtime in which the downstream API implementation executes

Discussion

Question 43

A system API has a guaranteed SLA of 100 ms per request. The system API is deployed to a primary environment as well as to a disaster recovery (DR) environment, with different DNS names in each environment. An upstream process API invokes the system API and the main goal of this process API is to respond to client requests in the least possible time. In what order should the system APIs be invoked, and what changes should be made in order to speed up the response time for requests from the process API?

Options:

In parallel, invoke the system API deployed to the primary environment and the system API deployed to the DR environment, and ONLY use the first response

In parallel, invoke the system API deployed to the primary environment and the system API deployed to the DR environment using a scatter-gather configured with a timeout, and then merge the responses

Invoke the system API deployed to the primary environment, and if it fails, invoke the system API deployed to the DR environment

Invoke ONLY the system API deployed to the primary environment, and add timeout and retry logic to avoid intermittent failures
