質問 2

An insurance provider is implementing Anypoint platform to manage its application infrastructure and is using the customer hosted runtime for its business due to certain financial requirements it must meet. It has built a number of synchronous API's and is currently hosting these on a mule runtime on one server These applications make use of a number of components including heavy use of object stores and VM queues.
Business has grown rapidly in the last year and the insurance provider is starting to receive reports of reliability issues from its applications.
The DevOps team indicates that the API's are currently handling too many requests and this is over loading the server. The team has also mentioned that there is a significant downtime when the server is down for maintenance.
As an integration architect, which option would you suggest to mitigate these issues?

（A）Add a load balancer and add additional servers in a server group configuration

（B）Add a load balancer and add additional servers in a cluster configuration

（C）Increase physical specifications of server CPU memory and network

（D）Change applications by use an event-driven model

質問 3

A Mule application is being designed To receive nightly a CSV file containing millions of records from an external vendor over SFTP, The records from the file need to be validated, transformed. And then written to a database. Records can be inserted into the database in any order.
In this use case, what combination of Mule components provides the most effective and performant way to write these records to the database?

（A）Use a Scatter-Gather to bulk insert records into the database

（B）Use a DataWeave map operation and an Async scope to insert records one by one into the database.

（C）Use a Batch job scope to bulk insert records into the database.

（D）Use a Parallel for Each scope to Insert records one by one into the database

質問 4

An API implementation is being developed to expose data from a production database via HTTP requests. The API implementation executes a database SELECT statement that is dynamically created based upon data received from each incoming HTTP request. The developers are planning to use various types of testing to make sure the Mule application works as expected, can handle specific workloads, and behaves correctly from an API consumer perspective. What type of testing would typically mock the results from each SELECT statement rather than actually execute it in the production database?

（A）Unit testing (white box)

（B）Performance testing

（C）Integration testing

（D）Functional testing (black box)

An organization has implemented the cluster with two customer hosted Mule runtimes is hosting an application.
This application has a flow with a JMS listener configured to consume messages from a queue destination. As an integration architect can you advise which JMS listener configuration must be used to receive messages in all the nodes of the cluster?

（A）Use the parameter primaryNodeOnly= "false" on the JMS listener with a shared subscription

（B）Use the parameter primaryNodeOnly= "false" on the JMS listener

（C）Use the parameter primaryNodeOnly= "true" on the JMS listener with a non*shared subscription

A leading bank implementing new mule API.
The purpose of API to fetch the customer account balances from the backend application and display them on the online platform the online banking platform. The online banking platform will send an array of accounts to Mule API get the account balances.
As a part of the processing the Mule API needs to insert the data into the database for auditing purposes and this process should not have any performance related implications on the account balance retrieval flow How should this requirement be implemented to achieve better throughput?

（A）Implement a try-catch scope to fetch the data from the back-end application and use the Async scope to insert records into the Audit database

（B）Implement parallel for each scope to fetch the data from the backend application and use Async scope to insert the records into the Audit database

（C）Implement the Async scope fetch the data from the backend application and to insert records in the Audit database

（D）Implement a for each scope to fetch the data from the back-end application and to insert records into the Audit database

An organization has decided on a cloud migration strategy to minimize the organization's own IT resources.
Currently the organization has all of its new applications running on its own premises and uses an on-premises load balancer that exposes all APIs under the base URL (https://api.rutujar.com).
As part of migration strategy, the organization is planning to migrate all of its new applications and load balancer CloudHub.
What is the most straightforward and cost-effective approach to Mule application deployment and load balancing that preserves the public URL's?

（A）For each migrated Mule application, deploy an API proxy application to Cloudhub with all traffic to the mule applications routed through a Cloud Hub Dedicated load balancer (DLB) Update a CNAME record for base URL ( https://api.rutujar.com) in the organization's DNS server to point to the A record of the CloudHub dedicated load balancer Apply mapping rules in DLB to map each API proxy application who is responding new application

（B）Deploy the Mule application to Cloudhub
Update a CNAME record for base URL ( https://api.rutujar.com) in the organization's DNS server to point to the A record of the CloudHub shared load balancer Apply mapping rules in SLB to map URLto their corresponding Mule applications

（C）Deploy the Mule application to Cloudhub
Create a CNAME record for base URL( httpsr://api.rutujar.com) in the Cloudhub shared load balancer that points to the A record of theon-premises load balancer Apply mapping rules in SLB to map URLto their corresponding Mule applications

（D）Deploy the Mule application to Cloudhub
Update a CNAME record for base URL ( https://api.rutujar.com) in the organization's DNS server to point to the A record of the Cloudhub dedicated load balancer Apply mapping rules in DLB to map URLto their corresponding Mule applications
