Question # 6

The AnyAirline organization's passenger reservations center is designing an integration solution that combines invocations of three different System APIs (bookFlight, bookHotel, and bookCar) in a business transaction. Each System API makes calls to a single database.

The entire business transaction must be rolled back when at least one of the APIs fails.

A.

Implement eXtended Architecture (XA) transactions between the API implementations

Coordinate between the API implementations using a Saga pattern

Implement caching in each API implementation to improve performance

B.

Implement local transactions within each API implementation

Configure each API implementation to also participate in the same eXtended Architecture (XA) transaction

Implement caching in each API implementation to improve performance

C.

Implement local transactions in each API implementation

Coordinate between the API implementations using a Saga pattern

Apply various compensating actions depending on where a failure occurs

D.

Implement an eXtended Architecture (XA) transaction manager in a Mule application using a Saga pattern

Connect each API implementation with the Mule application using XA transactions

Apply various compensating actions depending on where a failure occurs

Question # 7

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

Question # 8

A company is building an application network and has deployed four Mule APIs: one experience API, one process API, and two system APIs. The logs from all the APIs are aggregated in an external log aggregation tool. The company wants to trace messages that are exchanged between multiple API implementations. What is the most idiomatic (based on its intended use) identifier that should be used to implement Mule event tracing across the multiple API implementations?

A.

Mule event ID

B.

Mule correlation ID

C.

Client's IP address

D.

DataWeave UUID

Question # 9

An organization is implementing a Quote of the Day API that caches today's quote. What scenario can use the CloudHub Object Store connector to persist the cache's state?

A.

When there is one deployment of the API implementation to CloudHub and another one to customer hosted mule runtime that must share the cache state.

B.

When there are two CloudHub deployments of the API implementation by two Anypoint Platform business groups to the same CloudHub region that must share the cache state.

C.

When there is one CloudHub deployment of the API implementation to three workers that must share the cache state.

D.

When there are three CloudHub deployments of the API implementation to three separate CloudHub regions that must share the cache state.

Question # 10

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

Question # 11

Mule application is deployed to Customer Hosted Runtime. Asynchronous logging was implemented to improved throughput of the system. But it was observed over the period of time that few of the important exception log messages which were used to rollback transactions are not working as expected causing huge loss to the Organization. Organization wants to avoid these losses. Application also has constraints due to which they cant compromise on throughput much. What is the possible option in this case?

A.

Logging needs to be changed from asynchronous to synchronous

B.

External log appender needs to be used in this case

C.

Persistent memory storage should be used in such scenarios

D.

Mixed configuration of asynchronous or synchronous loggers should be used to log exceptions via synchronous way

Question # 12

As a part of project requirement, client will send a stream of data to mule application. Payload size can vary between 10mb to 5GB. Mule application is required to transform the data and send across multiple sftp servers. Due to the cost cuttings in the organization, mule application can only be allocated one worker with size of 0.2 vCore.

As an integration architect , which streaming strategy you would suggest to handle this scenario?

A.

In-memory non repeatable stream

B.

File based non-repeatable stream

C.

In-memory repeatable stream

D.

File based repeatable storage

Question # 13

An organization has strict unit test requirement that mandate every mule application must have an MUnit test suit with a test case defined for each flow and a minimum test coverage of 80%.

A developer is building Munit test suit for a newly developed mule application that sends API request toanexternal rest API.

What is the effective approach for successfully executing the Munit tests of this new application while still achieving the required test coverage for the Munit tests?

A.

Invoke the external endpoint of the rest API from the mule floors

B.

Mark the rest API invocations in the Munits and then call the mocking service flow that simulates standard responses from the REST API

C.

Mock the rest API invocation in the Munits and return a mock response for those invocations

D.

Create a mocking service flow to simulate standard responses from the rest API and then configure the mule flows to call the marking service flow

Question # 14

A mule application uses an HTTP request operation to involve an external API.

The external API follows the HTTP specification for proper status code usage.

What is possible cause when a 3xx status code is returned to the HTTP Request operation from the external API?

A.

The request was not accepted by the external API

B.

The request was Redirected to a different URL by the external API

Question # 15

A finance giant is planning to migrate all its Mule applications to Runtime fabric (RTF). Currently all Mule applications are deployed cloud hub using automated CI/CD scripts.

As an integration architect, which of the below step would you suggest to ensure that the applications from cloudhub are migrated properly to Runtime Fabric (RTF) with an assumption that organization is keen on keeping the same deployment strategy.

A.

No changes need to be made to POM.xml file and CI/CD script should be modified as per the RTF configurations

B.

runtimeFabric dependency should be added as a mule plug-in to POM.xml file and CI/CD script should be modified as per the RTF configurations

C.

runtimeFabric deployment should be added to POM.xml file in all

the mule applications and CI/CD script should be modified as per the RTF configurations

D.

runtimeFabric profile should be added mule configuration files in the mule applications and CI/CD script should be modified as per the RTF configurations
