NEW QUESTION # 21
Universal Containers has an Apex trigger on Account that creates an Account Plan record when an Account is marked as a Customer.
Recently a record-triggered flow was added so that whenever an Account is marked as a Customer, a
"Customer Since' date field is updated with today's date. Since the addition of the flow, two Account Plan records are created whenever the Account is marked as a Customer.
What might cause this to happen?
- A. The flow is configured to use an "Update Records' element.
- B. The Apex trigger is not bulk safe and calls insert inside of a for loop.
- C. The flow is configured to evaluate when a record is created and every time it is edited.
- D. The Apex trigger does not use a static variable to ensure it only fires once.
Answer: C
Explanation:
If a flow is configured to evaluate when a record is created and every time it's edited, and an Apex trigger also fires upon the same conditions, it could result in duplicate operations. In this case, two Account Plan records are created because both the flow and the trigger execute upon the Account being marked as a Customer.
NEW QUESTION # 22
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
- A. SELECT I4 FROM Account WHERE Name !- NULL
- B. SELECT 1d FROM Accounts WHERE Name != '°
AND Customer_Number_c- "ValueA' - C. SELECT Id FROM Account WHERE Name != ' 'AND IsDeleted = false
- D. SELECT ID FROM Account WHRE id IN :aListVariable
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 # 23
A company has a Lightning page with many Lightning Components, some that cache reference dat a. It is reported that the page does not always show the most current reference data.
What can a developer use to analyze and diagnose the problem in the Lightning page?
- A. Salesforce Lightning Inspector Actions tab
- B. Salesforce Lightning Inspector Transactions tab
- C. Salesforce Lightning Inspector Storage tab
- D. Salesforce Lightning Inspector Event Log tab
Answer: C
Explanation:
The Salesforce Lightning Inspector Storage tab is a tool that can be used to analyze and diagnose the problem of stale or outdated data in a Lightning page. The Storage tab shows the data that is stored in the browser cache by the Lightning components, such as reference data, metadata, and UI state. The developer can use the Storage tab to inspect the data, clear the cache, or disable the cache for debugging purposes. The developer can also use the Storage tab to monitor the cache performance and size, and identify any potential issues or bottlenecks.

NEW QUESTION # 25
A company has a custom component that allows users to search for records of a certain object type by invoking an Apex Controller that returns a list of results based on the user's input. When the search is completed, a searchComplete event is fired, with the results put in a results attribute of the event. The component is designed to be used within other components and may appear on a single page more than once.
What is the optimal code that should be added to fire the event when the search has completed?
- A.
- B.
- C.
- D.
Answer: B
Explanation:
The correct code to fire the event when the search has completed in a Lightning component is option B.
$A.get("e.c.searchComplete") is the syntax used to get the event, setParams is used to set the parameters, and fire is used to dispatch the event.References: Lightning Components Developer Guide - Firing Events
NEW QUESTION # 26
Consider the following code snippet:
The Apex method is executed in an environment with a large data volume count for Accounts, and the query is performing poorly.
Which technique should the developer implement to ensure the query performs optimally, while preserving the entire result set?
- A. Annotate the method w'th the @Future annotation.
- B. Break down the query into two individual queries and join the two result sets.
- C. Create a formula field to combine the CreateData and RecordType value, then Piter based on the formula.
- D. Use the Database, queryLocation method to retrieve the accounts.
Answer: B
NEW QUESTION # 27
A developer needs to implement a system audit feature that allows users, assigned to a custom profile named
"Auditors", to perform searches against the historical records in the Account object. The developer must ensure the search is able to return history records that are between 6 and 12 months old.
Given the code below, which select statement should be inserted below as a valid way to retrieve the Account History records ranging from 6 to 12 months old?
- A.
- B.
- C.
- D.
Answer: D
Explanation:
Given the code snippet, the correct query to retrieve Account History records between 6 and 12 months old would be the one that includes a WHERE clause filtering records where the CreatedDate is greater than or equal to initialDate and less than or equal to endDate. Option B's statement does this correctly by using the >
= and <= operators to define the range between initialDate (which is set to today's date minus 12 months) and endDate (set to today's date minus 6 months). Options A, C, and D either use incorrect comparison operators or compare against the wrong variables, resulting in an incorrect data set being returned.
