NEW QUESTION # 91
A Developer Edition org has five existing accounts. A developer wants to add 10 more accounts for testing purposes.
The following code is executed in the Developer Console using the Execute Anonymous window:
How many total accounts will be in the org after this code is executed?
- A. 0
- B. 1
- C. 2
- D. 3
Answer: A
Explanation:
The code snippet in question creates and inserts an account namedMyAccountand then initializes a loop to add additional accounts.
The loop runs fromx = 1and continues adding accounts untilx < 10.
Since the conditionx++is post-increment, the loop runs exactly 10 times, creating and adding 10 new accounts to thenewAccountslist.
At the end, theinsertDML statement persists these 10 new accounts, along with the already existing account (MyAccount).
Total accounts in the org:
Existing accounts = 5
New accounts added = 10
Total = 15

NEW QUESTION # 92
Consider the following code snippet:
Given the multi-tenant architecture of the Salesforce platform, what Is a best practice a developer should Implement and ensure successful execution of the method?
- A. Avoid using variables as query filters.
- B. Avoid executing queries without a limit clause.
- C. Avoid performing queries inside for loops.
- D. Avoid returning an empty List of records.
Answer: C
Explanation:
Performing queries inside loops is a common mistake that can lead to reaching governor limits quickly, especially in a multi-tenant environment like Salesforce where resources are shared among multiple users. It's essential to optimize the code for efficiency and performance by reducing the total number of SOQL queries whenever possible. This can be achieved by moving queries outside of loops, using collections to hold data, and leveraging bulkified methods. References: The related learning material can be found in the "Apex Basics
& Database" module on Trailhead, specifically in the unit titled "Write SOQL Queries"(1(https://trailhead.salesforce.com/content/learn/modules/apex_database/apex_database_soql%29%29.
I also noticed that you sent me an image along with your question. It seems to be a snippet of code written in Apex, which is used for Salesforce development. It shows a public static method named obtainAllFields that takes a Set of Ids as an argument and returns a List of Lead objects. Inside this method, there's a for loop that iterates over each Id from the provided Set and performs a SOQL query to fetch all fields of the Lead record with that specific Id. Each queried Lead record is then added to the result list which is returned after all iterations are complete. This is an example of performing queries inside loops, which is not a best practice and can cause governor limit issues.

NEW QUESTION # 95
Cloud kicks has a muli-screen flow its call center agents use when handling inbound service desk calls.
At one of the steps in the flow, the agents should be presented with a list of order number and dates that are retrieved from an external odrer management system in real time and displayed on the screen.
What shuold a developer use to satisfy this requirement?
- A. An apex REST class
- B. An invocae method
- C. An Apex Controller
- D. An outbound message
Answer: A
Explanation:
A developer should use an Apex REST class to satisfy this requirement. An Apex REST class can expose a custom REST API that can be called from an external system, such as an order management system, to retrieve data in real time and return it in JSON or XML format1. The developer can then use the @InvocableMethod annotation on a method in the Apex REST class to make it available as an action in Flow Builder2. The developer can then use this action in the multi-screen flow to display the list of order number and dates on the screen for the call center agents. References:

However, when the administrator tries to upload a list of 179 accounts using Data Loader, It fails with system. Exception errors. Which two actions should the developer take to fix the code segment shown above? Choose 2 answers
- A. Use Database.query to query the opportunities.
- B. Move the DML that saves opportunities outside the for loop.
- C. Check if all the required fields for Opportunity are being added on creation.
- D. Query for existing opportunities outside the for loop.
Answer: B,D
NEW QUESTION # 97
A developer is creating a Lightning web component to show a list of sales records.
The Sales Representative user should be able to see the commission field on each record. The Sales Assistant user should be able to see all fields on the record except the commission field.
How should this be enforced so that the component works for both users without showing any errors?
- A. Use Security.stripInaccessible Le to remove fields inaccessible to the current user.
- B. Use Lightning Locker Service to enforce sharing rules and field-level security.
- C. Use WITH SECURITY_ENFORCED In the SOQL that fetches the data for the component,
- D. Use Lightning Data Service to get the collection of sales records.
Answer: A
Explanation:
UsingSecurity.stripInaccessibleensures compliance with field-level security (FLS) and prevents users from accessing fields they do not have permission to view. In this scenario:
The commission field is inaccessible to Sales Assistants, andSecurity.stripInaccessiblewill automatically remove this field from the result set.
It prevents runtime errors when a user without proper access attempts to retrieve restricted fields.
Reference:Apex Developer Guide: Security.stripInaccessible

- A. By using the Database class to handle DML transactions.
- B. By using Maps to hold data from query results.
- C. By using a helper class that can be invoked from multiple triggers.
- D. By performing DML transactions on lists of SObjects.
Answer: B,D
NEW QUESTION # 99
A developer created this Apex trigger that calls Myclass.myStaticMethod:
The developer creates a test class with a test method that calls MyClass.myStaticMethod directly, resulting in
81% overall code coverage.
What happens when the developer tries to deploy the trigger and two classes to production, assuming no other code exists?
- A. The deployment fails because the Apex trigger has no code coverage.
- B. The deployment fails because no assertions were made in the test method.
- C. The deployment passes because the Apex code has the required >75% code coverage.
- D. The deployment passes because both classes and the trigger were included in the deployment.
Answer: C
Explanation:
The deployment will pass because the Apex code has the required >75% code coverage. In Salesforce, one of the prerequisites for deployment is that the Apex code must have at least 75% test coverage. This means that at least 75% of your Apex script must be executed by your test classes. Since in this case, the overall code coverage is 81%, it exceeds the minimum requirement, allowing for successful deployment. However, it is not a best practice to rely on indirect code coverage from other classes or triggers. The developer should write a separate test class for the trigger that covers all the possible scenarios and outcomes. Additionally, the test method should include assertions to verify the expected behavior and results of the code. References:

NEW QUESTION # 103
A developer created this Apex trigger that calls MyClass.myStaticMsthod:
The developer creates a test class with a test method that calls Myclass.myStacicMethod directly, resulting in 81% overall code coverage.
What happens when the developer tries to deploy the trigger and two classes to production, assuming no other code exists?
What happens when the developer tries to deploy the trigger and two classes to production, assuming no other code exists?
- A. The deployment passes because the Apex code has the required =75% code coverage.
- B. The deployment fails because the Apex trigger has no code coverage.
- C. The deployment passes because both classes and the trigger were included in the deployment.
- D. The deployment falls because no assertions were made in the test method.
Answer: B
Explanation:
Understanding the Scenario:
Trigger Definition:
trigger myTrigger on Contact (before insert) {
MyClass.myStaticMethod(trigger.new);
}
Test Class:
The test method calls MyClass.myStaticMethod directly.
Achieves 81% overall code coverage.
The trigger is not invoked during the test.
Key Points:
Code Coverage Requirements:
Minimum 75% Coverage: To deploy Apex code to production, all Apex classes and triggers must have at least 75% overall code coverage.
Trigger Coverage Requirement: All triggers must have some code coverage, meaning they cannot have 0% coverage.
Conclusion: Incorrect.
Option C:
Statement: The deployment fails because the Apex trigger has no code coverage.
Conclusion: Incorrect.
Best Practices:
Always Test Triggers: Ensure that your test methods perform operations that fire the triggers.
Example:
@isTest
public class MyTriggerTest {
static testMethod void testMyTrigger() {
Contact testContact = new Contact(LastName = 'Test');
insert testContact;
// Additional assertions can be added here
}
}
Use Assertions: While not causing deployment failure due to code coverage, assertions help validate that the code behaves as expected.
Reference:
Apex Developer Guide - Code Coverage
Deployment Guidelines
Implications for the Scenario:
Trigger Coverage:
Since the test method does not perform any operations that would fire the trigger (e.g., inserting a Contact record), the trigger myTrigger has 0% code coverage.
Overall Coverage:
Even though the classes achieve 81% coverage, the trigger's lack of coverage affects the deployment.
Deployment Outcome:
Deployment Fails: Because the trigger has 0% coverage, the deployment fails regardless of the overall coverage percentage.
Option Analysis:
Option A:
Statement: The deployment fails because no assertions were made in the test method.
Conclusion: Incorrect.
Option B:
Statement: The deployment passes because both classes and the trigger were included in the deployment.
Conclusion: Correct.
Option D:
Statement: The deployment passes because the Apex code has the required 75% code coverage.

NEW QUESTION # 106
Universal Containers (UC) uses a custom object called Vendor. The Vendor custom object has a master-detail relationship with the standard Account object.
Based on some internal discussions, the UC administrator tried to change the master-detail relationship to a lookup relationship, but was not able to do so.
What is a possible reason that this change was not permitted?
- A. The organization wide default for the Vendor object is Public Read/Write.
- B. Some of the Vendor records have null for the Account field.
- C. The Account object does not allow changing a field type for a custom field.
- D. The Account object has a roll up summary field on the Vendor object.
Answer: D
Explanation:
Master-detail relationships allow roll-up summary fields to aggregate data from child records. If a roll-up summary field exists on the Account object, the relationship cannot be changed to a lookup because lookup relationships do not support roll-up fields.
Why not other options?
A: Null values in the Vendor records do not prevent the change.
C: Custom fields can have their types changed as long as dependencies like roll-up fields are not present.
D: Organization-wide defaults do not affect the ability to change relationships.
