A) To schedule jobs to run at a later time
B) To handle complex asynchronous processing with chaining
C) To trigger workflow rules
D) To validate data before insertion
Answer: B) To handle complex asynchronous processing with chaining
Explanation: Queueable Apex provides more flexibility than future methods, including job chaining and handling complex objects.
3.
Which method in a batch Apex class is used to process each batch of records?
A) start()
B) execute()
C) finish()
D) process()
Answer: B) execute()
Explanation: The execute method is called for each batch of records to process them in chunks.
4.
What is a key difference between with sharing and without sharing keywords in Apex?
