MuleSoft Certified Developer - Level 1: All You Need to Know

The MuleSoft Certified Developer (MCD) certification demonstrates your skills in using Mule 4 to connect enterprise data and applications to the cloud.

This shows your understanding of Mule 4 concepts, including application networks, API design, and consumption, Mule events, data transformations, event flow control, error handling, batch processing, etc.

As a certified MuleSoft developer, you will become one of an organization's most sought-after and highly-paid professionals.

But how do you prepare for the certification MCD-level-1 exam? Need help finding the right platform to take the exam? Don't worry; we've got you covered.

In this post, we will let you know what to expect from the exam, including the format, content, duration, passing score, and much more.

What is Mulesoft?

MuleSoft Anypoint is a platform that enables event-driven architecture (EDA) and Mule Enterprise Service Bus (ESB). MuleSoft helps organizations innovate and transform faster by connecting applications, data, and devices with APIs. It allows capturing the demand and mapping the customer’s needs to a solution in the design phase. Customer feedback can be incorporated at this stage.

MuleSoft and Salesforce help businesses to unlock data across systems, create adaptive integration networks, and ultimately deliver them. The integration possibilities are endless with the various portfolio patterns, Salesforce components, and external systems.

Build connected apps with the Heroku and Lightning platforms and engage individual customers across the sales and service cloud. Sync and enrich data across Salesforce 360 with the MuleSoft connector.

Salesforce bought MuleSoft in 2018, mainly to speed up the digital transformation of its customers. With MuleSoft, data can be accessed across legacy systems, applications, and cloud devices, making decision-making more efficient and effective.

It provides a highly connected MuleSoft Anypoint platform (now part of the Salesforce Integration Cloud). MuleSoft also has an integration connector in Salesforce for seamless integration.

How does Mulesoft work?

MuleSoft offers many predefined APIs for all kinds of applications and systems. By pre-adding the API to the legacy system, you can instantly have a modern way of interacting with the system without knowing how it works. Each cloud system has an intermediate API called the system API, which modern system languages understand. Also, each MuleSoft API has a different function and is networked.

Using the API, the extracted data is processed in a more complex manner. Execute some logic, and the interactive API processes the data format to be presented on various multimedia devices (such as desktops, mobile phones, applications, etc.) and the development and execution of the API.

Customers want a connected experience. They don’t want to see the seams where their systems and departments meet. By simplifying the connection of applications, devices, and data, MuleSoft helps companies transform and innovate faster. APIs: Application Programming Interfaces: APIs accept requests and tell system users what they want. The messenger then sends back the response to the user.

The MuleSoft platform makes data unification easy, providing automated business processes, a single customer view, and creating connected customer experiences.

Through API-based integrations, each integration becomes a reusable building block. By simplifying a reusable process, businesses can accelerate IT adoption, increase organizational agility, and drive innovation at scale.

The results speak for organizations. Forrester found that MuleSoft customers achieved a 445% return on investment in just three years and saved up to 90% of development time by maintaining APIs and integrations.

What is the MuleSoft Certified Developer - Level 1 certification?

The MuleSoft Certified Developer - Level 1 should be capable of working on basic Mule 4 projects under guidance and supervision.
