An API implementation is being designed that must invoke an Order API which is known to repeatedly experience downtime. For this reason a fallback API is to be called when the Order API is unavailable.
What approach to designing invocation of the fallback API provides the best resilience?
- A . Redirect client requests through an HTTP 303 temporary redirect status code to the fallback API whenever the Order API is unavailable
- B . Set an option in the HTTP Requester component that invokes the order API to instead invoke a fallback API whenever an HTTP 4XX or 5XX response status code is received from Order API
- C . Create a separate entry for the order API in API manager and then invoke this API as a fallback API if the primary Order API is unavailable
- D . Search Anypoint Exchange for a suitable existing fallback API and them implement invocations to their fallback API in addition to the Order API
A
Explanation:
* Resilience testing is a type of software testing that observes how applications act under stress. It’s meant to ensure the product’s ability to perform in chaotic conditions without a loss of core functions or data; it ensures a quick recovery after unforeseen, uncontrollable events.
* In case an API invocation fails ― even after a certain number of retries ― it might be adequate to invoke a different API as a fallback. A fallback API, by definition, will never be ideal for the purpose of the API client, otherwise it would be the primary API.
* Here are some examples for fallback APIs:
– An old, deprecated version of the same API.
– An alternative endpoint of the same API and version (e.g. API in another CloudHub region).
– An API doing more than required, and therefore not as performant as the primary API.
– An API doing less than required and therefore forcing the API Client to offer a degraded service, which is still better than no service at all.
* API clients implemented as Mule applications offer the ‘Until Successful Scope and Exception’ strategies at their disposal, which together allow configuring fallback actions such as a fallback API invocation.
* All HTTP response status codes within the 3xx category are considered redirection messages. These codes indicate to the user agent (i.e. your web browser) that an additional action is required in order to complete the request and access the desired resource

Hence correct answer is Redirect client requests through an HTTP 303 temporary redirect status code to the fallback API whenever the Order API is unavailable
An organization has an HTTPS-enabled Mule application named Orders API that receives requests from another Mule application named Process Orders.
The communication between these two Mule applications must be secured by TLS mutual authentication (two-way TLS).
At a minimum, what must be stored in each truststore and keystore of these two Mule applications to properly support two-way TLS between the two Mule applications while properly protecting each Mule application’s keys?
- A . Orders API truststore: The Orders API public key
Process Orders keystore: The Process Orders private key and public key - B . Orders API truststore: The Orders API private key and public key
Process Orders keystore: The Process Orders private key public key - C . Orders API truststore: The Process Orders public key
Orders API keystore: The Orders API private key and public key
Process Orders truststore: The Orders API public key
Process Orders keystore: The Process Orders private key and public key - D . Orders API truststore: The Process Orders public key
Orders API keystore: The Orders API private key
Process Orders truststore: The Orders API public key
Process Orders keystore: The Process Orders private key
C

As an enterprise architect, what are the two reasons for which you would use a canonical data model in the new integration project using Mulesoft Anypoint platform (choose two answers )
- A . To have consistent data structure aligned in processes
- B . To isolate areas within a bounded context
- C . To incorporate industry standard data formats
- D . There are multiple canonical definitions of each data type
- E . Because the model isolates the back and systems and support mule applications from change
Insurance organization is planning to deploy Mule application in MuleSoft Hosted runtime plane. As a part of requirement, application should be scalable. highly available. It also has regulatory requirement which demands logs to be retained for at least 2 years. As an Integration Architect what step you will recommend in order to achieve this?
- A . It is not possible to store logs for 2 years in CloudHub deployment. External log management system is required.
- B . When deploying an application to CloudHub, logs retention period should be selected as 2 years
- C . When deploying an application to CloudHub, worker size should be sufficient to store 2 years data
- D . Logging strategy should be configured accordingly in log4j file deployed with the application.
A
Explanation:
Correct answer is It is not possible to store logs for 2 years in CloudHub deployment. External log management system is required. CloudHub has a specific log retention policy, as described in the documentation: the platform stores logs of up to 100 MB per app & per worker or for up to 30 days, whichever limit is hit first. Once this limit has been reached, the oldest log information is deleted in chunks and is irretrievably lost. The recommended approach is to persist your logs to a external logging system of your choice (such as Splunk, for instance) using a log appender. Please note that this solution results in the logs no longer being stored on our platform, so any support cases you lodge will require for you to provide the appropriate logs for review and case resolution
A project uses Jenkins to implement CI/CD process. It was observed that each Mule package contains some of the Jenkins files and folders for configurations of CI/CD jobs.
As these files and folders are not part of the actual package, expectation is that these should not be part of deployed archive.
Which file can be used to exclude these files and folders from the deployed archive?
- A . muleignore
- B . _unTrackMule
- C . mulelnclude
- D . _muleExclude
As part of a growth strategy, a supplier signs a trading agreement with a large customer. The customer sends purchase orders to the supplier according to the ANSI X12 EDI standard, and the supplier creates the orders in its ERP system using the information in the EDI document.
The agreement also requires that the supplier provide a new RESTful API to process request from the customer for current product inventory level from the supplier’ s ERP system.
Which two fundamental integration use cases does the supplier need to deliver to provide an end-to-end solution for this business scenario? (Choose two.)
- A . Synchronized data transfer
- B . Sharing data with external partners
- C . User interface integration
- D . Streaming data ingestion
- E . Data mashups
A MuteSoft developer must implement an API as a Mule application, run the application locally, and execute unit tests against the Running application.
Which Anypoint Platform component can the developer use to full all of these requirements?
- A . API Manager
- B . API Designer
- C . Anypoint CLI
- D . Anypoint Studio
A global organization operates datacenters in many countries. There are private network links between these datacenters because all business data (but NOT metadata) must be exchanged over these private network connections.
The organization does not currently use AWS in any way.
The strategic decision has Just been made to rigorously minimize IT operations effort and investment going forward.
What combination of deployment options of the Anypoint Platform control plane and runtime plane(s) best serves this organization at the start of this strategic journey?
- A . MuleSoft-hosted Anypoint Platform control plane CloudHub Shared Worker Cloud in multiple AWS regions
- B . Anypoint Platform – Private Cloud Edition Customer-hosted runtime plane in each datacenter
- C . MuleSoft-hosted Anypoint Platform control plane Customer-hosted runtime plane in multiple AWS regions
- D . MuleSoft-hosted Anypoint Platform control plane Customer-hosted runtime plane in each datacenter
D
Explanation:
Correct answer is MuleSoft-hosted Anypoint Platform control plane Customer-hosted runtime plane in each datacenter There are two things to note about the question which can help us figure out correct answer.
* Business data must be exchanged over these private network connections which means we can not use MuleSoft provided Cloudhub option. So we are left with either customer hosted runtime in external cloud provider or customer hosted runtime in their own premises. As customer does not use AWS at the moment. Hence that don’t have the immediate option of using Customer-hosted runtime plane in multiple AWS regions. hence the most suitable option for runtime plane is Customer-hosted runtime plane in each datacenter
* Metadata has no limitation to reside in organization premises. Hence for control plane MuleSoft hosted Anypoint platform can be used as a strategic solution.
Hybrid is the best choice to start. Mule hosted Control plane and Customer hosted Runtime to start with.Once they mature in cloud migration, everything can be in Mule hosted.
A key Cl/CD capability of any enterprise solution is a testing framework to write and run repeatable tests.
