Salesforce Updated PDI Exam Questions and Answers by zaviyar

When multiple triggers are associated with the same object and event, Salesforce does not guarantee the order of execution. This is why it is a best practice to consolidate all logic into a single trigger per object and control execution order using helper classes.

sObject:SOQL queries can return single or multiple records assObjectinstances.

List:SOQL queries often return results as aListofsObject.

Double:SOQL aggregate queries can return numeric data types likeDouble(e.g., COUNT, SUM).

The code snippet in question creates and inserts an account namedMyAccountand then initializes a loop to add additional accounts.

The loop runs fromx = 1and continues adding accounts untilx < 10.

Since the conditionx++is post-increment, the loop runs exactly 10 times, creating and adding 10 new accounts to thenewAccountslist.

At the end, theinsertDML statement persists these 10 new accounts, along with the already existing account (MyAccount).

Total accounts in the org:

Existing accounts = 5

New accounts added = 10

Total = 15
