Preparing for the CRT-450 Exam: Key Questions and Answers
Permalink   
 

The Salesforce Certified Platform Developer I (CRT-450) exam is a critical step for developers looking to validate their skills in building custom applications on the Salesforce platform. Here are some essential questions and answers to help you prepare:

1. What is Apex? Apex is a strongly-typed, object-oriented programming language that allows developers to execute flow and transaction control statements on Salesforce servers. It is syntactically similar to Java and acts as a backend language for Salesforce.

2. How do you declare a list in Apex? To declare a list in Apex, you use the List keyword followed by the data type of the elements. For example:

3. What is a trigger in Salesforce? A trigger is a piece of Apex code that executes before or after specific database events, such as insert, update, delete, or undelete. Triggers are used to perform custom actions based on these events.

4. Explain the difference between SOQL and SOSL. SOQL (Salesforce Object Query Language) is used to query records from a single object or multiple related objects. SOSL (Salesforce Object Search Language) is used to search for records across multiple objects.

5. What are governor limits in Salesforce? Governor limits are runtime limits enforced by the Salesforce platform to ensure efficient use of shared resources. These include limits on the number of SOQL queries, DML operations, and CPU time per transaction.
