Salesforce Certified Platform Developer I Sample Questions (Q183-Q188):

NEW QUESTION # 183
Cloud Kicks Fitness, an ISV Salesforce partner, is developing a managed package application. One of the application modules allows the user to calculate body fat using the Apex class, BodyFat, and its method, calculateBodyFat (). The product owner wants to ensure this method is accessible by the consumer of the application when developing customizations outside the ISV's package namespace.
Which approach should a developer take to ensure calculateBodyFat () is accessible outside the package namespace?

A. Declare the class as global and use the public access modifier on the method.
B. Declare the class as public and use the global access modifier on the method.
C. Declare the class and method using the global access modifier.
D. Declare the class and method using the public access modifier.

Answer: C

Explanation:
ISV Package Development:
The ISV is developing a managed package.
They have an Apex class BodyFat with a method calculateBodyFat().
Requirement:
Ensure calculateBodyFat() is accessible by consumers outside the package namespace.
Solution:
To allow methods in a managed package to be accessible outside the package namespace, they must be declared as global.
Option B: Declare the class and method using the global access modifier.
Correct Approach.
Global Classes and Methods:
In managed packages, only classes and methods declared as global are accessible outside the package namespace.
Declaration:
global class BodyFat {
global void calculateBodyFat() {
// method implementation
}
}
Important Notes:
Public classes and methods in managed packages are accessible only within the namespace.
Global is required to expose the functionality to subscribers.
The method must also be declared as global to be accessible outside the namespace.
Using public on the method limits its accessibility to within the namespace.
Option C: Declare the class and method using the public access modifier.
Incorrect.
Public classes and methods in a managed package are only accessible within the package's namespace.
They are not accessible to subscribers.
Option D: Declare the class as public and use the global access modifier on the method.
Incorrect.
The class must be declared as global to be accessible outside the namespace.
A public class cannot contain global methods.
Conclusion:
To ensure calculateBodyFat() is accessible outside the package namespace, both the class and method must be declared as global.
Therefore, Option B is the correct choice.
Reference:
Apex Class Access Modifiers
Developing Packages with Apex
Why Other Options are Not Suitable:
Option A: Declare the class as global and use the public access modifier on the method.
Incorrect.

NEW QUESTION # 187
Which salesforce org has a complete duplicate copy of the production org including data and configuration?

A. Partial Copy Sandbox
B. Production
C. Full Sandbox
D. Developer Pro Sandbox

Answer: C

Explanation:
A Full Sandbox is a type of sandbox that has a complete duplicate copy of the production org, including all the data and configuration. A Full Sandbox is useful for testing and development purposes, as it allows the developer to perform any changes or operations without affecting the production org. A Full Sandbox also supports performance testing, load testing, and staging1.
The other options are not correct because:
* A Developer Pro Sandbox is a type of sandbox that has a copy of the production org's configuration (metadata) and some data. A Developer Pro Sandbox is limited by storage space and can only hold up to
1 GB of data1.
* A Partial Copy Sandbox is a type of sandbox that has a copy of the production org's configuration and a sample of the data. A Partial Copy Sandbox is limited by storage space and can only hold up to 5 GB of data. The data is selected based on a sandbox template that defines the objects and records to include1.
* A Production org is not a duplicate copy of itself, but the original org where the live data and processes are stored. A Production org is not meant for testing or development purposes, as any changes or operations can affect the users and the business2.
