Question 5

A developer created a new after insert trigger on the Lead object that creates Task records for each Lead.

After deploying to production, an existing outside integration that inserts Lead records in batches to Salesforce is occasionally reporting total batch failures being caused by the Task insert statement. This causes the integration process in the outside system to stop, requiring a manual restart.

Which change should the developer make to allow the integration to continue when some records in a batch cause failures due to the Task

insert statement, so that manual restarts are not needed?

AUse the Database method with allow one set to false.

BDeactivate the trigger before the integration runs.

CRemove the Apex class from the integration user's profile.

DUse a try-catch block after the insert statement.

Question 6

Which statement generates a list of Leads and Contacts that have a field with the phrase 'ACME'?

AOption A

BOption B

COption C

DOption D

Answer : B

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.
