NEW QUESTION # 75
A develop completed modification to a customized feature that is comprised of two elements:
Apex trigger
Trigger handler Apex class
What are two factors that the developer must take into account to properly deploy the modification to the production environment?
- A. All methods in the test classes must use @isTest.
- B. Test methods must be declared with the testMethod keyword.
- C. At least one line of code must be executed for the Apex trigger.
- D. Apex classes must have at least 75% code coverage org-wide.
Answer: C,D
Explanation:
To deploy Apex code to a production environment, the developer must ensure that the Apex classes have at least 75% code coverage org-wide, and that all triggers have some code coverage. This means that at least one line of code must be executed for the Apex trigger during the test execution. Code coverage is a measure of how many lines of code are executed by the test methods. Code coverage helps to ensure that the Apex code works as expected and that it does not break any existing functionality. Code coverage also helps to prevent deploying code that has not been tested or that has bugs. All methods in the test classes must use @isTest or the testMethod keyword, but this is not a factor for deploying the modification, as it is a requirement for creating the test classes in the first place. The @isTest annotation and the testMethod keyword are equivalent ways of marking a method as a test method. Test methods are methods that verify the functionality of the Apex code and do not count against the code limit of the organization. References:

NEW QUESTION # 80
Assuming that naze is 8 String obtained by an <apex:inpotText> tag on 8 Visualforce page, which two SOQL queries performed are safe from SOQL injection?
'Choose 2 answers
- A.
- B.
- C.
- D.
Answer: A,C
Explanation:
SOQL injection is a vulnerability that occurs when user-supplied input is used to construct a dynamic SOQL query without proper validation or escaping. This can allow an attacker to modify the query and execute unintended commands or access unauthorized data. To prevent SOQL injection, it is recommended to use static queries with bind variables or use the escapeSingleQuotes method to sanitize the input. Based on the image descriptions from my tool outputs, the following options are safe from SOQL injection:
* Option A: This option uses a static query with a bind variable, which automatically escapes any malicious input and prevents it from changing the query structure. The bind variable name is obtained from an apex:inputText tag on a Visualforce page and is used as a filter for the Account Name field.
* Option C: This option also uses a static query with a bind variable, which is the same as option A. The only difference is that the bind variable name is obtained from a different apex:inputText tag on the same Visualforce page and is used as a filter for the Contact Name field.
The other options are not safe from SOQL injection because they use dynamic queries with string concatenation, which can allow an attacker to inject SOQL commands into the query string and bypass the intended logic or access unauthorized data.
References: The use of static queries with bind variables and the escapeSingleQuotes method to prevent SOQL injection can be referenced in the Salesforce Platform Developer I learning documents, specifically in modules that cover Apex security and SOQL, such as:
* SOQL Injection
* Secure Coding SQL Injection
* Apex Basics & Database

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: D
Explanation:
The code snippet provided in the image is a Salesforce Apex code that is used to create new accounts in a Salesforce org. Initially, there are five existing accounts. In the provided Apex code, one account named
'MyAccount' is created and inserted into the org, making the total six accounts. Then, a loop is executed to create and add ten more new accounts (named 'New Account 1' to 'New Account 10') into the org using a do-while loop that runs while x is less than 10 (starting from x=1). So, after executing this code, there will be an additional eleven accounts added to the initial five accounts making it a total of fifteen (5 initial + 11 new =
16) accounts in the org. References: The explanation can be corroborated with knowledge of Apex programming on Salesforce's official learning platform Trailhead and related documentation.
