Salesforce Updated MuleSoft-Integration-Architect-I Exam Questions and Answers by elyas

Explanation

* Correct answer is To directly reference one shared and customized log4j2.xml file from multiple Mule applications. Key word  to note in the answer is directly.

* By default, CloudHub replaces a Mule application's log4j2.xml file with a CloudHub log4j2.xml file. This specifies the CloudHub appender to write logs to the CloudHub logging service.

* You cannot modify CloudHub log4j2.xml file to add any custom appender. But there is a process in order to achieve this. You need to raise a request on support portal to disable CloudHub provided Mule application log4j2 file.

* Once this is done , Mule application's log4j2.xml file is used which you can use to send/export application logs to other log4j2 appenders, such as a custom logging system MuleSoft does not own any responsibility for lost logging data due to misconfiguration of your own log4j appender if it happens by any chance.

* One more difference between customer-hosted Mule runtimes and CloudHub deployed mule instance is that

- CloudHub system log messages cannot be sent to external log management system without installing custom CH logging configuration through support

- where as Customer-hosted runtime can send system and application log to external log management system

A synchronous invocation of a RESTful API using HTTP to get an individual customer record from a single system exemplifies the request-reply interaction pattern. In this pattern, a client sends a request to a service and waits for a response. The interaction is synchronous because the client expects an immediate reply and is blocked until it receives the response.

This pattern is common in scenarios where the client needs to retrieve specific data or perform an action that requires immediate feedback from the server, such as retrieving a customer record from a database.

To monitor Mule applications deployed on customer-hosted Mule runtimes from Anypoint Platform, you need to enable monitoring for each application within the Runtime Manager's application settings. This step ensures that the Runtime Manager Agent, which is already part of the Mule runtime, will collect and send monitoring data to Anypoint Monitoring.

The Runtime Manager Agent acts as the intermediary, collecting metrics and operational data from the Mule applications and transmitting this data to Anypoint Monitoring for analysis and visualization. This setup provides real-time insights and allows for effective monitoring and management of Mule applications.

MuleSoft customers often favor a MuleSoft-hosted Anypoint Platform runtime plane over a customer-hosted runtime for the following reasons:

• Reduced time-to-market for the first application (C): Using a MuleSoft-hosted runtime plane accelerates the deployment process because MuleSoft manages the infrastructure, allowing customers to focus on developing and deploying their applications quickly. This leads to faster time-to-market for the initial application and subsequent updates.
• Reduced IT operations effort (E): By leveraging a MuleSoft-hosted environment, customers offload the operational responsibilities, such as infrastructure maintenance, updates, and scalability management, to MuleSoft. This reduces the IT operations workload and allows internal teams to focus on more strategic initiatives.

In contrast, other options like reduced application latency and increased application throughput are not directly influenced by whether the runtime plane is MuleSoft-hosted or customer-hosted.
