Question 34
An environment has two Apex triggers: an after-update trigger on Account and an after-update trigger on Contact.
The Account after-update trigger fires whenever an Account's address is updated, and it updates every associated Contact with that address. The Contact after-update trigger fires on every edit, and it updates every Campaign Member record related to the Contact with the Contact's state.
Consider the following: A mass update of 200 Account records' addresses, where each Account has 50 Contacts. Each Contact has one Campaign Member. This means there are 10,000 Contact records across the Accounts and 10,000 Campaign Member records across the contacts.
What will happen when the mass update occurs?
