質問 # 104
Given the following Apex statement: Account myAccount = [SELECT Id, Name FROM Account]; What occurs when more than one Account is returned by the SOQL query?
正解：D
解説：
Answer A is 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.
質問 # 105
A developer is tasked to perform a security review of the ContactSearch Apex class that exists in the system.
Within the class, the developer identifies the following method as a security threat:
ist<Contact> performSearch (String lastName} [
return Database.query('SELECT Id, FirstName, LastName FROM Contact WHERE LastName Like s'+lastName+'s'")?; What are two ways the developer can update the method to prevent a SOQL injection attack?
Choose 2 answers
正解：B、C
解説：
Option A: Using variable binding eliminates the need for concatenating dynamic values in the query, which is the safest approach.
Option B: UsingString.escapeSingleQuotesensures special characters are handled safely, reducing the risk of SOQL injection.
Not Suitable:
Option C: Whilewith sharingensures sharing rules are applied, it does not prevent SOQL injection.
Option D: Regular expressions are not a reliable method for sanitizing input.
Preventing SOQL Injection
質問 # 106
A developer declared a class as follow.
public class wysiwyg { // Properties and methods including DML }
Which invocation of a class method will obey the organization-wide defaults and sharing settings for the running user in the Salesforce Organization?
正解：B
質問 # 107
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?
正解：D
解説：
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.
質問 # 108
What are two benefits of using declarative customizations over code?
Choose 2 answer
正解：B、D
解説：
Declarative customizations, such as workflows, process builder, validation rules, and flows, offer a no-code approach to customizing Salesforce. Below are the key benefits:
* Declarative customizations automatically update with each Salesforce release (A):Salesforce ensures that declarative tools are automatically updated during new releases, eliminating the need for manual intervention or code refactoring.
