Why a try/catch block is required:
In Salesforce, DML operations such as insert, update, delete, and upsert can throw exceptions due to issues like validation rule violations, field constraints, or sharing rule restrictions.
Using a try/catch block ensures that these exceptions are caught and handled gracefully, preventing the entire transaction from failing.
How to modify the code:
The update statement in the code can be wrapped in a try/catch block to catch and handle any exceptions that occur. For example:
apex
Copy code
public static void insertAccounts(List<Account> theseAccounts) {
try {
for (Account thisAccount : theseAccounts) {
if (thisAccount.website == null) {
thisAccount.website = 'https://www.demo.com';
}
}
update theseAccounts;
} catch (DmlException e) {
System.debug('DML Exception: ' + e.getMessage());
}
}
Why not the other options?
A . Implement the upsert DML statement:
upsert is used to either insert or update records based on an external ID or primary key. It does not inherently handle exceptions.
B . Implement Change Data Capture:
Change Data Capture (CDC) is used for tracking changes to data in real time and is unrelated to handling DML exceptions.
D . Remove null items from the list of Accounts:
While cleaning the input data is a good practice, it does not address the need for exception handling during DML operations.

Correct Syntax for SOSL Query:
Option B uses SOSL (Salesforce Object Search Language) to find records where the phrase 'ACME' appears in any field across multiple objects (Contact and Lead).
Syntax used in Option B:
List<List<SObject>> searchList = [FIND 'ACME' IN ALL FIELDS RETURNING Contact, Lead]; This query retrieves a list of SObject lists, where each inner list contains the results for a specific object (e.g., Contact or Lead).
Why not the other options?
A . Option A:
This uses SOQL (Salesforce Object Query Language), not SOSL. SOQL cannot search across multiple objects or fields. The syntax provided is invalid because SOQL doesn't support "multi-object WHERE conditions." C . Option C:
The Map<SObject> syntax is incorrect for SOSL queries. SOSL queries return a List<List<SObject>>, not a Map<SObject>.
D . Option D:
The syntax List<SObject> for SOSL is incorrect. SOSL must return List<List<SObject>> since the results are grouped by object types.
