NEW QUESTION # 12
Which two best practices should the developer implement to optimize this code? Choose 2 answers
Answer: B,D
Explanation:
To optimize the code in question, it's important to follow best practices that reduce the number of SOQL queries and DML statements within loops, as these can quickly consume governor limits and lead to inefficiencies. Option C is correct because using a collection to hold records and performing a single DML operation outside of loops reduces the number of DML operations, which is a best practice for bulkifying code in Salesforce. Option D is also correct because querying records outside of a loop prevents hitting SOQL governor limits and makes the code more efficient. Options A and B are not correct in the context provided, as there isn't enough information to determine if changing the trigger context is necessary, and removing the DML statement altogether may not be feasible if the logic requires data to be persisted.

NEW QUESTION # 13
Consider the following code snippet:
A developer created the following test class to provide the proper code coverage for the snippet above:
However, when the test runs, no data is returned and the assertion fails. Which edit should the developer make to ensure the test class runs successfully?
Answer: D
Explanation:
To ensure that the test class for a search functionality in Salesforce runs successfully, the developer should use the Test.setFixedSearchResults() method. This allows the test to specify the records that are returned by the search, ensuring that the search behavior is predictable and that the assertion can be properly evaluated.
NEW QUESTION # 14
Universal Containers wants to use a Customer Community with Customer Community Plus licenses to allow their customers access to track how many containers they have rented and when they are due back. Universal Containers uses a Private sharing model for External users, Many of their customers are multi-national corporations with complex Account hierarchies. Each account on the hierarchy represents a department within the same business, One of the requirements is to allow certain community users within the same Account hierarchy to see several departments' containers, based on a custom junction object that relates the Contact to the various Account records that represent the departments.
Which solution solves these requirements?
Answer: B
Explanation:
For community users within the same Account hierarchy to see records based on a custom junction object, Apex managed sharing can be used. An Apex trigger can create sharing records based on the junction object relationships, allowing users to see records from different departments as required.
NEW QUESTION # 15
Which code snippet processes records in the most memory efficient manner, avoiding governor limits such as "Apex heap size too large"?
A)
B) C)
D)
Answer: B
Explanation:
Option D, which uses the Database.query() method in combination with a for loop, is the most memory-efficient way to process records. This is known as the Query Locator pattern, which allows you to work with a large number of records by querying them in batches. This approach helps to avoid hitting the governor limit for "Apex heap size too large" as it processes one record at a time from the database without storing the entire result set in memory.

B)
C)
D)
Answer: A
