NEW QUESTION # 164
A developer created a Lightning web component that uses a lightning-record-edit-form to collect information about Leads. Users complain that they only see one error message at a time about their input when trying to save a Lead record.
What is the recommended approach to perform validations on more than one field, and display multiple error messages simultaneously with minimal JavaScript intervention?
Answer: D
Explanation:
The recommended approach to perform validations on more than one field, and display multiple error messages simultaneously with minimal JavaScript intervention is to use an external JavaScript library. An external JavaScript library is a collection of reusable code that can provide additional functionality and features to the Lightning web component. The developer can use an external JavaScript library that supports form validation, such as jQuery Validation or Parsley.js, and import it into the Lightning web component. The developer can then use the library's methods and options to define the validation rules and messages for each field, and to display the errors on the component. Using a try/catch/finally block will not help, as it is used to handle exceptions and errors in the code, but it does not perform validations on the fields or display error messages. Using validation rules will not help, as they are used to enforce data quality and integrity on the server side, but they do not perform validations on the client side or display error messages on the component. Using an Apex trigger will not help, as it is used to execute logic before or after a record is inserted, updated, deleted, or undeleted, but it does not perform validations on the client side or display error messages on the component.

NEW QUESTION # 165
A developer created an Apex class that updates an Account based on input from a Lightning web component that Is used to register an Account. The update to the Account should only be made if it has not already been registered.
What should the developer do to ensure that users do not overwrite each other's updates to the same Account if they make updates at the same time?




Answer: A
Explanation:
When multiple users are updating the same record at the same time, there is a risk of overwriting each other's changes. Salesforce provides a mechanism called 'record locking' to prevent this from happening.
Option D is correct because including FOR UPDATE in the SOQL query locks the retrieved records for the duration of the transaction. This prevents other transactions from updating the record until the current transaction is complete, which is essential for avoiding race conditions where two users might overwrite each other's updates.
Option A is incorrect because while adding a try/catch block around the update operation is good practice for handling exceptions, it does not prevent overwrites from concurrent updates.
Option B is incorrect because using upsert instead of update does not address the problem of concurrent updates. The upsert operation is used to either insert a new record or update an existing one based on whether a record with a matching ID or external ID already exists.
Option C is incorrect because FOR UPDATE should be used in the SOQL query to lock the records, not in the SELECT statement itself.

Answer: B
NEW QUESTION # 167
The use of the transient keyword in Visualforce page controllers helps with which common performance issue?
Answer: A
Explanation:
The transient keyword in Visualforce page controllers marks variables that should not be part of the view state, which can significantly reduce the size of the view state. This can help avoid view state limit errors and improve page performance because a smaller view state requires less time to send to the client.References:
