1. Question 1Process Automation and Logic

   A developer needs a class-level value that is set once and cannot be reassigned anywhere in the code. Which declaration meets this need?

   1. Astatic final Integer MAX_ROWS = 100;
   2. Bpublic Integer MAX_ROWS = 100;
   3. Cstatic Integer MAX_ROWS = 100;
   4. Dprivate const Integer MAX_ROWS = 100;

   Correct answer: A

   The static modifier ties the value to the class, and final stops it from being reassigned after it is set. The instance field and the plain static field can both be changed, and const is not an Apex keyword.

2. Question 2Developer Fundamentals

   A developer is modeling Project__c records that must always belong to an Account, must be deleted automatically when that Account is deleted, and should take their sharing access from the Account. Which relationship type should be created on Project__c?

   1. AA master-detail relationship to Account
   2. BA lookup relationship to Account that is optional
   3. CA hierarchical relationship to Account
   4. DAn external lookup relationship to Account
   Show answer and explanationHide answer

   Correct answer: A

   A master-detail relationship makes the child required, cascades deletes from the parent, and inherits sharing from it. A lookup is optional with no cascade delete, hierarchical relationships exist only on the User object, and external lookups point to external data rather than Account records.

3. Question 3User Interface

   A Visualforce page displays a comment that a user typed into an apex:outputText component. A tester enters a script tag, and the script must not run in the browser. What default behaviour protects the page?

   1. AVisualforce strips every character that is not a letter or number from the value before display
   2. BVisualforce escapes the output by default, so the characters display as text rather than running
   3. CVisualforce disables all JavaScript on any page that shows data entered by an end user
   4. DVisualforce stores user input in an encrypted form so that the browser cannot decode the script text
   Show answer and explanationHide answer

   Correct answer: B

   Visualforce output components escape special characters by default because the escape attribute is true, so the browser renders the script as plain text. Stripping characters, disabling all JavaScript, or encrypting the input are not how this default protection works.

4. Question 4Testing, Debugging, and Deployment

   Before a team deploys Apex to a production org, it asks what minimum share of Apex code must be covered by tests. Which answer is correct?

   1. ASeventy-five percent overall coverage of the lines in the org's Apex classes and triggers
   2. BFifty percent overall coverage of the lines in the org's Apex classes and triggers
   3. CNinety percent coverage of the lines in each individual Apex class and trigger in the org
   4. DOne hundred percent coverage of the lines in each individual Apex class and trigger in the org
   Show answer and explanationHide answer

   Correct answer: A

   Production deployments require at least 75 percent overall Apex code coverage across the org. Fifty percent falls below the required threshold, while the 90 and 100 percent options describe targets that are not the minimum requirement.

5. Question 5Process Automation and Logic

   A developer defines a global interface named Notifier with one method, send(). Which statement describes how a class must use this interface?

   1. AThe class uses extends and inherits the send() body from the interface
   2. BThe interface is instantiated with new, and the class calls send() on that instance
   3. CThe class uses implements and must provide its own body for send()
   4. DThe class receives send() automatically without code if it sits in the same namespace
   Show answer and explanationHide answer

   Correct answer: C

   A class uses implements and must write a body for every method the interface declares, because Apex interfaces contain only method signatures. extends is for classes, interfaces cannot be instantiated, and no implementation is supplied automatically.
