Question # 61

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?

Options:

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.

Question # 62

As a part of project , existing java implementation is being migrated to Mulesoft. Business is very tight on the budget and wish to complete the project in most economical way possible.

Canonical object model using java is already a part of existing implementation. Same object model is required by mule application for a business use case. What is the best way to achieve this?

Options:

A.  

Make use of Java module

B.  

Create similar model for Mule applications

C.  

Create a custom application to read Java code and make it available for Mule application

D.  

Use Anypoint exchange

Question # 64

A Mule application is synchronizing customer data between two different database systems.

What is the main benefit of using eXtended Architecture (XA) transactions over local transactions to synchronize these two different database systems?

Options:

A.  

An XA transaction synchronizes the database systems with the least amount of Mule configuration or coding

B.  

An XA transaction handles the largest number of requests in the shortest time

C.  

An XA transaction automatically rolls back operations against both database systems if any operation falls

D.  

An XA transaction writes to both database systems as fast as possible

Question # 65

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?

Options:

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 # 66

A retail company is implementing a MuleSoft API to get inventory details from two vendors by Invoking each vendor's online applications. Due to network issues, the invocations to the vendor applications are timing out intermittently, but the requests are successful after re-invoking each

vendor application.

What is the most performant way of implementing the API to invoke each vendor application and to retry invocations that generate timeout errors?

Options:

A.  

Use a For-Each scope to invoke the two vendor applications in series, one after the other.

Place the For-Each scope inside an Until-Successful scope to retry requests that raise timeout errors.

B.  

Use a Choice scope to Invoke each vendor application on a separate route.

Place the Choice scope inside an Until-Successful scope to retry requests that raise

timeout errors.

C.  

Use a Scatter-Gather scope to invoke each vendor application on a separate route.

Use an Until-Successful scope in each route to retry requests that raise timeout errors.

D.  

Use a Round-Robin scope to invoke each vendor application on a separate route.

Use a Try-Catch scope in each route to retry requests that raise timeout errors.

Question # 68

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?

Options:

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

Each Mule application is expected to be configured with two(2) Cloudhub workers.This is expected to result in several Mule application deployments per hour.

Options:

A.  

10.0.0.0/21(2048 IPs)

B.  

10.0.0.0/22(1024IPs)
