The Salesforce Platform Developer I exam is an essential credential for aspiring developers looking to build and customize applications on the Salesforce platform. Whether you’re new to Salesforce or have some experience under your belt, you might be wondering – how hard is this exam to crack? This blog post dives deep into the Platform Developer I exam structure, explores the factors that impact its difficulty, and equips you with valuable tips and resources to conquer it with confidence.
Salesforce Platform Developer I Exam Structure
The Salesforce Platform Developer I Credential is designed for those with expertise in creating custom applications on the Lightning Platform. This certification covers the essential programming skills needed to develop custom business logic and interfaces on Salesforce using Apex, Visualforce, and Lightning components. Candidates must pass the Salesforce Platform Developer I exam to earn this credential, which also serves as a prerequisite for the Salesforce Platform Developer II multiple-choice exam.
The Salesforce Platform Developer I exam has 60 multiple-choice/multiple-select questions at you, testing your knowledge across various aspects of the platform. You’ll have 105 minutes to demonstrate your understanding, and a passing score of 68% (41 correct answers) is required to earn the Platform Developer I certification.
The exam delves into two core development approaches on Salesforce: declarative automation and programmatic development. Declarative automation utilizes tools like workflows, process builders, and Lightning Flow to automate business processes without writing code. Programmatic development, on the other hand, involves leveraging the power of Apex, a powerful object-oriented programming language, to create custom applications and functionalities. However, get a detailed breakdown of the key areas the Platform Developer I exam focuses on:
- Understanding the Divide: Declarative vs. Programmatic: The exam assesses your ability to distinguish between scenarios where declarative automation is sufficient and situations that necessitate programmatic development.
- Apex Programming Fundamentals: Get ready to be grilled on the fundamentals of Apex programming, including variables, data types, control flow statements (loops, conditional statements), and data manipulation techniques (CRUD operations – Create, Read, Update, and Delete).
- Querying the Platform: SOQL, SOSL, and DML: Mastering Salesforce Object Query Language (SOQL) and Salesforce Object Search Language (SOSL) is crucial. You’ll be tested on your ability to craft queries to retrieve and search data effectively. Additionally, expect questions on Data Manipulation Language (DML) statements used to modify data within the Salesforce platform.
- Visualforce Basics: Building user interfaces is an essential skill for Salesforce developers. The exam will assess your grasp of Visualforce concepts like building pages, using components, and interacting with Apex controllers using the controller binding syntax.
- Security Considerations: Developing secure applications is paramount in Salesforce. The exam might touch upon security best practices like data security, user permissions, and code access controls.
Factors Affecting Salesforce Platform Developer I Exam Difficulty
Passing the Salesforce Platform Developer I exam depends on a variety of factors. Here are the key elements that can influence the perceived difficulty of the Platform Developer I exam:
1. Prior Programming Experience:
Having a solid foundation in programming languages can significantly smoothen your path to Platform Developer I success. The Salesforce Platform Developer I Exam targets individuals with experience in developing and deploying basic business logic and user interfaces using the Lightning Platform’s programmatic capabilities. This includes the practical application of skills and concepts detailed in the exam objectives. Typically, candidates have one to two years of development experience, including at least six months working with the Lightning Platform, and have studied the recommended resources listed in the exam guide.
Furthermore, the Salesforce Platform Developer I candidate should have the following experience, skills, and knowledge:
- Experience with data-driven applications and relational databases
- Proficiency in object-oriented languages like Apex, JavaScript, Java, C#, and Ruby
- Familiarity with governor limits and their effects
- Understanding of Model View Controller (MVC) and component-based architectures
- Knowledge of the core objects in the Salesforce schema
- Understanding of the capabilities and use cases for formula fields and roll-up summary fields
- Ability to determine when to use declarative vs. programmatic methods to meet business requirements
- Ability to utilize the platform’s relevant declarative features when appropriate
- Proficiency in the Apex programming language and best practices for customizing Salesforce
- Ability to extend the Lightning Platform using Apex, basic Lightning components, and Visualforce
- Capability to use fundamental programmatic features of the Lightning Platform to develop custom interfaces and business logic
- Familiarity with testing, debugging, and deploying code, and understanding of the available environments
2. Hands-on Practice:
Theoretical knowledge is valuable, but true mastery comes from practical application. Actively engage in hands-on exercises and projects to solidify your understanding of Apex syntax, SOQL queries, and Visualforce concepts. Salesforce’s Trailhead platform offers a plethora of modules, playgrounds, and Superbadges specifically designed to provide hands-on learning experiences. The more you code and experiment, the more comfortable you’ll feel tackling exam challenges.
3. Time Management is Crucial:
The Platform Developer I exam has 60 questions your way within a time limit of 105 minutes. Effective time management becomes paramount to ensure you attempt all questions and have sufficient time for review. Here are some strategies to ace your time management:
- Practice with timed tests: Utilize practice tests available online or through Salesforce resources to simulate the actual exam environment. This will help you gauge your reading speed and question-solving pace.
- Prioritize effectively: Not all questions carry equal weight. Learn to identify questions that can be solved quickly and allocate more time to complex ones. Don’t get bogged down on a single question; flag it for review and move on.
- Review strategically: After completing the initial rounds, dedicate the remaining time to reviewing flagged questions and any areas where you might have doubts. Don’t rush through the review process – a second glance can make all the difference.
