Salesforce MuleSoft-Integration-Architect-I - Salesforce Certified MuleSoft Platform Integration Architect (Mule-Arch-202)

To monitor Mule applications deployed to different customer-hosted Mule runtimes using Anypoint Monitoring, follow these steps:

Install Anypoint Monitoring Agent: Install an Anypoint Monitoring agent on each Mule runtime. This agent is responsible for collecting monitoring data from the Mule applications running on that runtime.

Data Transmission: Each Anypoint Monitoring agent sends the collected monitoring data directly to Anypoint Monitoring. This ensures that performance metrics, logs, and other relevant data are available for analysis and monitoring within the Anypoint Platform.

By using the Anypoint Monitoring agent, organizations can effectively monitor their Mule applications across various environments, ensuring visibility and operational efficiency.

Explanation

Correct answer is Untill Successful scope can be implemented while calling backend API's The Until Successful scope repeatedly triggers the scope's components (including flow references) until they all succeed or until a maximum number of retries is exceeded The scope provides option to control the max number of retries and the interval between retries The scope can execute any sequence of processors that may fail for whatever reason and may succeed upon retry

Explanation

* XA transaction add tremendous latency so "Reduce Latency" is incorrect option XA transactions define "All or No" commit protocol.

* Each local XA resource manager supports the A.C.I.D properties (Atomicity, Consistency, Isolation, and Durability).

---------------------------------------------------------------------------------------------------------------------

So correct choice is "Ensure consistency"

Explanation

Correct answer is Consistency as XA transactions are implemented to achieve this. XA transactions are added in the implementation to achieve goal of ACID properties. In the context of transaction processing, the acronym ACID refers to the four key properties of a transaction: atomicity, consistency, isolation, and durability. Atomicity : All changes to data are performed as if they are a single operation. That is, all the changes are performed, or none of them are. For example, in an application that transfers funds from one account to another, the atomicity property ensures that, if a debit is made successfully from one account, the corresponding credit is made to the other account. Consistency : Data is in a consistent state when a transaction starts and when it ends.For example, in an application that transfers funds from one account to another, the consistency property ensures that the total value of funds in both the accounts is the same at the start and end of each transaction. Isolation : The intermediate state of a transaction is invisible to other transactions. As a result, transactions that run concurrently appear to be serialized. For example, in an application that transfers funds from one account to another, the isolation property ensures that another transaction sees the transferred funds in one account or the other, but not in both, nor in neither. Durability : After a transaction successfully completes, changes to data persist and are not undone, even in the event of a system failure. For example, in an application that transfers funds from one account to another, the durability property ensures that the changes made to each account will not be reversed.

Explanation

* An X.509 certificate is a vital safeguard against malicious network impersonators. Without x.509 server authentication, man-in-the-middle attacks can be initiated by malicious access points, compromised routers, etc.

* X.509 is most used for SSL/TLS connections to ensure that the client (e.g., a web browser) is not fooled by a malicious impersonator pretending to be a known, trustworthy website.

* Coming to the question , we can not use SLB here as SLB does not allow to define vanity domain names. * Hence we need to use DLB and add certificate in there

---------------------------------------------------------------------------------------------------------------------

Hence correct answer is Add the X 509 certificate to the cloudhub Dedicated Load Balancer (DLB), not the Mule application. Create the CNAME for api.acme.com pointing to the DLB’s record

A major distinguishing characteristic of an application network, according to MuleSoft, is that it is built for change and self-service. An application network connects applications, data, and devices with APIs, enabling self-service access and reuse of assets. This architecture allows organizations to rapidly adapt to changing business needs, fosters innovation, and reduces time to market by empowering different teams to access and integrate systems independently without waiting for centralized IT.

Explanation

* Any change in the application will require a restart except when the issue outside the app. For below situations , you would need to redeploy the code after doing necessary changes

-- One of the stored procedures being called by the Mule application has been renamed. In this case, in the Mule application you will have to do changes to accommodate the new stored procedure name.

-- Required redesign of Mule applications to follow microservice architecture principles. As code is changed, deployment is must

-- If the credentials changed and you need to update the connector or the properties.

-- The credentials for accessing the database have been updated and the previous credentials are no longer valid. In this situation you need to restart or redeploy depending on how credentials are configured in Mule application.

* So Correct answer is The database server was unavailable for four hours due to a major outage but is now fully operational again as this is the only external issue to application.

Anypoint Exchange is the Anypoint Platform component that helps integration developers discover and share reusable APIs, connectors, and templates. It acts as a central repository where developers can publish and access various assets, facilitating reuse and collaboration within the organization. By using Anypoint Exchange, developers can reduce duplication of effort, speed up development processes, and ensure consistency across integrations.

Other components like API Manager, Anypoint Studio, and Design Center serve different purposes, such as managing APIs, developing Mule applications, and designing API specifications, but they are not specifically focused on discovering and sharing reusable assets.
