The best way to declare maxAttempts to meet the requirements is to declare it as a private static variable on a helper class. This will ensure that the variable is initialized only once per Apex transaction, and that its value is preserved and shared across trigger executions. A private static variable is a variable that belongs to a class and not an instance, and that can only be accessed within the class. A helper class is a class that contains common methods or variables that can be used by other classes or triggers.
References: The use of private static variables and helper classes can be referenced in the Salesforce Platform Developer I learning documents, specifically in modules that cover Apex basics and triggers, such as:
* Apex Basics & Database
* Apex Triggers
* Apex Testing
