NEW QUESTION # 34
A developer created an Opportunity trigger that updates the account rating when an associated opportunity is considered high value. Current criteria for an opportunity to be considered high value is an amount greater than or equal to $1,000,000. However, this criteria value can change over time.
There is a new requirement to also display high value opportunities in a Lightning web component.
Which two actions should the developer take to meet these business requirements, and also prevent the business logic that obtains the high value opportunities from being repeated in more than one place?
Choose 2 answers
Answer: A,D
Explanation:
Creating a helper class allows the logic to be centralized and reused in both the trigger and the Lightning Web Component (LWC), avoiding repetition. Using custom metadata to store the criteria value allows easy updates without code changes and can be referenced from both the helper class and the trigger.

NEW QUESTION # 35
A Visuzlforce page loads slowly due to the large amount of data it displays.
Which strategy can a developer use to improve the performance?
Answer: C
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.
NEW QUESTION # 36
A developer is building a complex commission calculation engine in Apex that is called from an Opportunity trigger. During QA it was reported that the calculations are incorrect.
The developer has representative test data and passing test methods in their developer sandbox.
Which three tools or techniques could the developer use to execute the code and pause it at key lines to visually inspect values of various Apex variables?
Choose 3 answers
Answer: C,D,E
Explanation:
To debug and troubleshoot the commission calculation engine, a developer can use several tools provided by Salesforce to inspect and pause the execution of Apex code.
Apex Interactive Debugger: It allows real-time debugging of Apex code execution. With this tool, a developer can set breakpoints, step through code, inspect variables, and evaluate expressions.
Developer Console: Although the Developer Console does not allow interactive debugging, it does provide the ability to view logs that capture the execution of code. Debug logs can be inspected to understand the flow of execution and values of variables at different points in time.
Apex Replay Debugger: This tool is part of Salesforce Extensions for Visual Studio Code. It allows a developer to replay a debug log as if they are stepping through the code line by line, which can be very useful to inspect the state of variables at specific points in the execution.

NEW QUESTION # 37
Consider the queries in the options below and the following Information:
* For these queries, assume that there are more than 200,000 Account records.
* These records Include soft-deleted records; that is, deleted records that are still in the Recycle Bin.
* There are two fields that are marked as External Id on the
Account. These fields are customer_Number_c and ERR_Key_ s.
Which two queries are optimized for large data volumes?
Choose 2 answers
Answer: B,C
Explanation:
For optimizing queries, especially on large data volumes, it's recommended to use indexed fields such as External ID fields, which will make the queries selective. Among the options given:
B) is optimized because it is using the Customer_Number__c field, which is an External ID and hence indexed.
D) is also optimized because it filters out deleted records with IsDeleted = false and uses Name != ' ', which is likely to be selective.
Using indexed fields and filtering out unnecessary records helps in faster query execution on large data volumes.

NEW QUESTION # 38
Consider the Apex controller below, that is called from an Aura component.
What is wrong with this code?
Answer: B
Explanation:
The method defined in the Apex class must be static to be used as an Aura-enabled method. Aura-enabled methods need to be static because they are called by the Lightning framework without instantiating the class.
