Salesforce Certified Platform Developer I Sample Questions (Q17-Q22):

NEW QUESTION # 17
A developer writes a trigger on the Account object on the before update event that increments a count field. A workflow rule also increments the count field every time that an Account is created or updated. The field update in the workflow rule is configured to not re-evaluate workflow rules.
What is the value of the count field if an Account is inserted with an initial value of zero, assuming no other automation logic is implemented on the Account?

  • A. 0
  • B. 1
  • C. 2
  • D. 3

Answer: A


NEW QUESTION # 18
How many Accounts will be inserted by the following block of code?

  • A. 0
  • B. 1
  • C. 2
  • D. 3

Answer: C

Explanation:
Execution Flow:
The loop runs 500 times (iranges from 0 to 499).
In each iteration, a newAccountrecord is created and inserted.
Governor Limits:
This code violates the governor limit of 150 DML statements per transaction because eachinsertis executed individually.
However, the code logically attempts to insert 500 accounts.
Key Consideration:
The code demonstrates inefficient handling of DML operations and would fail in a real-world scenario.
References:Governor Limits:https://developer.salesforce.com/docs/atlas.en-us.apexcode.meta/apexcode
/apex_gov_limits.htm


NEW QUESTION # 19
Consider the following code snippet:
public static List<Lead> obtainAllFields(Set<Id> leadIds) {
List<Lead> result = new List<Lead>();
for (Id leadId : leadIds) {
result.add([SELECT FIELDS(ALL) FROM Lead WHERE Id = :leadId]);
}
return result;
}
Given the multi-tenant architecture of the Salesforce platform, what is a best practice a developer should implement to ensure successful execution of the method?

  • A. Avoid returning an empty List of records.
  • B. Avoid using variables as query filters.
  • C. Avoid performing queries inside for loops.
  • D. Avoid executing queries without a limit clause.

Answer: C

Explanation:
Comprehensive and Detailed Explanation From Exact Extract:
The provided code runs a SOQL query inside a for loop, which violates Salesforce's governor limit of 100 SOQL queries per transaction. To avoid hitting these limits, the best practice is to perform queries outside of loops by using a single query that retrieves all required records at once.

NEW QUESTION # 20
A developer has an integer variable called maxAttempts. The developer needs to ensure that once maxAttempts is initialized, it preserves its value for the length of the Apex transaction; while being able to share the variable's state between trigger executions.
How should the developer declare maxAttempts to meet these requirements?

  • A. Declare maxattempts as a member variable on the trigger definition.
  • B. Declare maxattempts as a variable on a helper class.
  • C. Declare maxattempts as a constant using the static and final keywords.
  • D. Declare maxAttempts as a private static variable on a helper class.

Answer: D

Explanation:
To preserve the value ofmaxAttemptsfor the length of the Apex transaction and share its state between trigger executions:
Static Variable:
Static variables are initialized once per transaction and retain their value throughout the transaction.
They can be accessed without instantiating the class.
Private Scope:
Declaring it as private ensures encapsulation and prevents unintended external modification.
Helper Class:
Using a helper class ensures the separation of concerns, keeping trigger logic clean and adhering to best practices.
Example Code:public class HelperClass {
private static Integer maxAttempts = 5; // Default value
public static Integer getMaxAttempts() {
return maxAttempts;
}
public static void setMaxAttempts(Integer attempts) {
maxAttempts = attempts;
}
}
A:Constants (static + final) cannot be modified after initialization.
B:Trigger member variables cannot retain values across executions within the same transaction.
C:Declaring it as a non-static variable in a helper class would reset its value during each trigger execution.
Why Not the Other Options?


NEW QUESTION # 21
Which two are phases in the Aura application event propagation framework?
Choose 2 answers

  • A. Bubble
  • B. Control
  • C. Emit
  • D. Default

Answer: A,D

Explanation:
In the Aura framework, application events propagate through the component hierarchy in specific phases. The two main phases are:
Option A: Bubble
Correct Phase.
In the bubble phase, the event propagates upward from the source component to the root component.
Components can handle the event during this phase by registering an event handler with phase="bubble".
The default phase occurs after the capture and bubble phases.
It's used for default processing that occurs unless the event is stopped during the earlier phases.
Handlers registered without specifying a phase default to this phase.
There is no 'Control' phase in the Aura event propagation framework.
Option D: Emit
Not a Phase.
'Emit' refers to the action of firing or dispatching an event.
It is not a phase in the event propagation process.
Conclusion:
The two phases in the Aura application event propagation framework are Bubble (Option A) and Default (Option C).
Understanding these phases is essential for managing event handling in Aura components.
Reference:

Option C: Default
Correct Phase.

Options Not Accurate:
Option B: Control
