PD1 Process Automation & Logic 3

Question 1

Which governor limit applies per synchronous Apex transaction regardless of how many triggers or classes are involved?

Accepted Answer

All of the above apply per transaction

Answer

All Apex governor limits—SOQL queries, DML statements, and SOQL rows—apply cumulatively across the entire synchronous transaction, not per class.

Question 2

A developer needs to call an external REST API from a trigger asynchronously. Which Apex feature is most appropriate?

Accepted Answer

Future method annotated with @future(callout=true)

Answer

Callouts from triggers must be asynchronous; a `@future(callout=true)` method runs after the transaction commits and allows HTTP callouts.

Question 3

What is the maximum number of records a single Apex Batch `execute()` method can process per batch chunk by default?

Accepted Answer

200

Answer

The default batch size for Apex Batch is 200 records per execute() call, though a custom size can be set in Database.executeBatch().

Question 4

A developer writes a SOQL query inside a for loop in a trigger. What problem does this cause?

Accepted Answer

Risk of hitting the 100 SOQL queries per transaction governor limit

Answer

Each loop iteration issues a new SOQL query, quickly consuming the 100-query limit in bulk operations—this is an anti-pattern to avoid.

Question 5

Which statement about Process Builder is TRUE as of Salesforce's recommended best practices?

Accepted Answer

Process Builder should be migrated to Flow Builder as it is being retired

Answer

Salesforce has announced Process Builder retirement; developers should build new automation in Flow Builder and migrate existing processes.
