B. Custom object

Question # 2
Which statement is true regarding savepoints?
A. You can roll back to any savepoint variable created in any order.
B. Static variables are not reverted during a rollback.
C. Reference to savepoints can cross trigger invocations.
D. Savepoints are not limited by DML statement governor limits.


B. Static variables are not reverted during a rollback.


Question # 3
A developer is asked to develop a new AppFxchange application. A feature of the program creates Survey records when a Case reaches a certain stage and is of a certain Record Type. This feature needs to be configurable, as different Salesforce instances require Surveys at different times. Additionally, the out-of-the-box AppExchange app needs to come with a set of best practice settings that apply to most customers. What should the developer use to store and package the custom configuration settings for the app?
A. Custom objects
B. Custom settings
C. Custom metadata
D. Custom labels


C. Custom metadata


Question # 4
Universal Containers develops a Visualforce page that requires the inclusion of external JavaScript and C55 files. They want to ensure efficient loading and caching of the page. Which feature should be utilized to achieve this goal?
A. ActionFunction
B. PageBlockTable
C. Static resources
D. RemoteAction


C. Static resources


Question # 5
Consider the below trigger intended to assign the Account to the manager of the Account's region:
A. Option A
B. Option B
C. Option C
D. Option D


B. Option B
C. Option C

Explanation: The best practices for writing triggers in Salesforce include bulkifying your code to handle multiple records efficiently and reducing the number of SOQL queries, especially within loops, to avoid hitting governor limits.
Option B is correct because moving the SOQL query outside of the for loop is essential to bulkify the trigger. Performing a query within a loop can cause a SOQL governor limit to be reached if the trigger is processing many records. The best practice is to collect all necessary data before the loop starts and then process it within the loop.
Option C is correct as well, because using a Map to cache the results of a SOQL query by Id is another way to bulkify the code. This allows you to query all the necessary data once and then access it efficiently in memory, avoiding repeated queries.
Option A is incorrect because adding isExecuting before the update doesn't address any best practices related to bulkification or SOQL query optimization.
Option D is incorrect because the last line should not be removed if the developer intends to perform DML on the accountList. However, this line should be outside of the loop and is unnecessary if the trigger context is 'before insert' or 'before update', since in those contexts, changes to records in Trigger.new are implicitly saved without the need for explicit DML.

Question # 6
A Visuzlforce page loads slowly due to the large amount of data it displays. Which strategy can a developer use to improve the performance?
A. Use lazy loading to load the data on demand, instead of in the controller's constructor.
B. Use an
C. Use the transient keyword for the List variables used in the custom controller.
D. Use Javascript to move data processing to the browser instead of the controller.


A. Use lazy loading to load the data on demand, instead of in the controller's constructor.

Explanation: Lazy loading is a strategy to improve the performance of a Visualforce page that loads a large amount of data. By loading the data on demand, rather than in the controller's constructor, the initial page load is faster, and additional data is only loaded when necessary.

Question # 7
For compliance purposes, a company is required to track long-term product usage in their org. The information that they need to log will be collected from more than one object and, over time, they predict they will have hundreds of millions of records. What should a developer use to implement this?
A. Setup audit trail
B. Field audit trail
C. Big objects
D. Field history tracking


C. Big objects


Question # 8

The application must acknowledge and respect the user's locale context for dates, times, numbers, currency, and currency symbols. When using Aura components, which approach should the developer implement to ensure the Lightning application complies with the user's locale?
A. Use the $User global variable to retrieve the user preferences.
B. Use the $Label global value provider.
C. Use the $Lacale value provider to retrieve the user preferences.
D. Create a Hierarchical custom setting to store user preferences.


C. Use the $Lacale value provider to retrieve the user preferences.
