NEW QUESTION # 180
Which two events need to happen when deploying to a production org?
Answer: B,C
Explanation:
Answers A, B are correct. Salesforce delivery depends on repeatable testing and controlled deployment. Apex tests create isolated data, validate behavior, and supply code coverage for production deployment. Salesforce CLI, scratch orgs, sandboxes, debug logs, trace flags, and Apex Jobs give developers the tooling needed to build, test, diagnose, and release changes across environments. The other options either use the wrong platform feature, apply at the wrong layer, or ignore a key Salesforce constraint. For Platform Developer I, the important point is not just syntax; it is choosing the feature that aligns with transaction behavior, security enforcement, maintainability, and supported metadata capabilities. Reference focus: Salesforce Apex Developer Guide, Salesforce CLI Developer Guide, Tooling API documentation, and Salesforce Help deployment guidance. This distinction is important in production orgs because small design mistakes can create deployment failures, runtime exceptions, data-quality defects, or user-visible security gaps once automation is executed in bulk or from multiple entry points.

NEW QUESTION # 182
A developer considers the following snippet of code:
Based an this code, what is the value of x?
Answer: C
Explanation:
* TheBoolean isOKvariable is declared but not initialized, meaning its value isnullby default in Apex.
* The code evaluates theif-elseconditions in sequence:
* Condition 1:isOK == false && theString == 'Hello'
* isOKisnull, so this evaluates tofalse.
* Condition 2:isOK == true && theString == 'Hello'
* Again,isOKisnull, so this evaluates tofalse.
* Condition 3:isOK != null && theString == 'Hello'
* isOKisnull, soisOK != nullevaluates tofalse.
* Else block: None of the above conditions are true, so the code enters theelseblock and setsx = 4.

NEW QUESTION # 183
A lead developer creates an Apex interface called Laptop. Consider the following code snippet:
public class SilverLaptop{
//code implementation
How can a developer use the Laptop interface within the silverLaptop class?
Answer: C
Explanation:
* To use an Apex interface within a class, the class must implement the interface using theimplementskeyword. This is the correct way to inherit behavior defined in an interface.
Example:
public class SilverLaptop implements Laptop {
// Implementation of the methods defined in the Laptop interface
}
Why not other options?
* B: Theextendskeyword is used for inheriting from a class, not implementing an interface.
* C: This syntax is incorrect and not supported in Apex.
* D: This syntax is also incorrect as interfaces are not referenced with an@Interfaceannotation in Apex.
